Next. 541 00:29:16,440 --> 00:29:20,520 Moving on to Recommendation 2, this is set at priority 4 542 00:29:20,520 --> 00:29:22,920 with a focus over the next five to seven years, 543 00:29:22,920 --> 00:29:25,240 addressing the needs for improving our understanding 544 00:29:25,240 --> 00:29:26,680 of the benefits, burdens, 545 00:29:26,680 --> 00:29:29,040 and harms of screening for cognitive impairment. 546 00:29:29,040 --> 00:29:31,200 Specifically, in the absence of a patient 547 00:29:31,200 --> 00:29:32,760 care partner or clinician report 548 00:29:32,760 --> 00:29:35,800 of cognitive, behavioral, or functional changes. 549 00:29:35,800 --> 00:29:38,200 A strong emphasis is yet again placed on the importance 550 00:29:38,200 --> 00:29:40,600 of having any early detection strategy 551 00:29:40,600 --> 00:29:43,800 linked to diagnostic services and quality care. 552 00:29:43,800 --> 00:29:46,320 In addition, research studies should be able to determine 553 00:29:46,320 --> 00:29:48,800 whether certain populations are more likely to benefit 554 00:29:48,800 --> 00:29:51,840 from screening as well as whether other populations 555 00:29:51,840 --> 00:29:54,800 may be more likely to be harmed. Next. 556 00:29:57,440 --> 00:30:00,000 The justification for Recommendation 2 flows directly 557 00:30:00,000 --> 00:30:02,760 From the US Preventive Services Task Force 558 00:30:02,760 --> 00:30:06,080 continued I or insufficient evidence recommendation 559 00:30:06,080 --> 00:30:07,800 made as recently as February 2020, 560 00:30:07,800 --> 00:30:10,800 with regard to cognitive screening. Next. 561 00:30:13,400 --> 00:30:15,000 The primary reason was that, in fact, 562 00:30:15,000 --> 00:30:16,920 there continues to be very limited data 563 00:30:16,920 --> 00:30:20,040 investigating benefits and harms of cognitive screening. 564 00:30:20,040 --> 00:30:21,480 One trial by Fowler and colleagues 565 00:30:21,480 --> 00:30:22,840 was recently conducted, 566 00:30:22,840 --> 00:30:24,920 finding no differences in quality of life 567 00:30:24,920 --> 00:30:27,640 among those who did or did not receive screening. 568 00:30:27,640 --> 00:30:29,120 Prior to the Fowler study, 569 00:30:29,120 --> 00:30:30,680 scant evidence has been available 570 00:30:30,680 --> 00:30:33,560 to further inform the Task Force. 571 00:30:33,560 --> 00:30:37,160 Other justifications for the lack of endorsement of cognitive 572 00:30:37,160 --> 00:30:40,200 screening includes the lack of accurate well-tested instruments 573 00:30:40,200 --> 00:30:41,880 for assessing cognitive impairment 574 00:30:41,880 --> 00:30:44,040 that would work in primary care settings 575 00:30:44,040 --> 00:30:45,560 and that there also is little evidence 576 00:30:45,560 --> 00:30:47,200 supporting any benefit from screening 577 00:30:47,200 --> 00:30:49,800 or any earlier diagnosis on decision-making. 578 00:30:49,800 --> 00:30:51,920 Yet there's also mixed evidence on potential harms 579 00:30:51,920 --> 00:30:55,880 due to false positives derived from diagnostic inaccuracies. 580 00:30:55,880 --> 00:30:58,960 Next. 581 00:30:58,960 --> 00:31:01,160 Interestingly, we do have a natural experiment 582 00:31:01,160 --> 00:31:03,400 brewing with the Medicare annual wellness visit. 583 00:31:03,400 --> 00:31:05,360 These covered primary care encounters have been around 584 00:31:05,360 --> 00:31:08,400 since 2011 and require a cognitive assessment. 585 00:31:08,400 --> 00:31:09,920 So, in essence, despite the US 586 00:31:09,920 --> 00:31:12,200 Preventive Services Task Force recommendations, 587 00:31:12,200 --> 00:31:14,240 there is a cognitive screening mandate. 588 00:31:14,240 --> 00:31:15,680 However, Medicare wellness visits 589 00:31:15,680 --> 00:31:18,240 are often not performed for a myriad of reasons. 590 00:31:18,240 --> 00:31:20,840 And, when they are performed, as many as half may not include 591 00:31:20,840 --> 00:31:22,800 the required cognitive assessment. 592 00:31:22,800 --> 00:31:24,520 A prior Alzheimer's Association survey 593 00:31:24,520 --> 00:31:26,280 found one in five primary care doctors 594 00:31:26,280 --> 00:31:28,440 were unaware that such a Medicare visit 595 00:31:28,440 --> 00:31:30,120 required a cognitive screening, 596 00:31:30,120 --> 00:31:32,400 this after several years of Medicare annual wellness 597 00:31:32,400 --> 00:31:35,400 visit being in place next. 598 00:31:37,680 --> 00:31:39,400 Finally, as we move forward, 599 00:31:39,400 --> 00:31:41,400 an important take-home to reiterate 600 00:31:41,400 --> 00:31:42,960 is the need to develop strategies 601 00:31:42,960 --> 00:31:44,600 for early detection of cognitive impairment 602 00:31:44,600 --> 00:31:46,600 that will not widen existing disparities 603 00:31:46,600 --> 00:31:49,160 by not having adequate linkages to quality care 604 00:31:49,160 --> 00:31:50,560 and clear recommendations 605 00:31:50,560 --> 00:31:53,240 for ongoing follow-up and care management. 606 00:31:53,240 --> 00:31:54,960 Partnerships, partnerships with CMS 607 00:31:54,960 --> 00:31:56,560 and other large health systems 608 00:31:56,560 --> 00:31:59,200 might also expedite answers for Recommendation 2 609 00:31:59,200 --> 00:32:02,440 by examining the Medicare annual wellness visit data. 610 00:32:02,440 --> 00:32:04,000 Thank you. 611 00:32:07,800 --> 00:32:09,400 -Alright. Great. 612 00:32:09,400 --> 00:32:13,000 So how I'm Jeff Burns, thanks Mike. 613 00:32:13,000 --> 00:32:16,000 I am going to discuss recommendation 614 00:32:16,000 --> 00:32:18,960 three in this focus area about detecting 615 00:32:18,960 --> 00:32:21,280 and diagnosing cognitive impairment 616 00:32:21,280 --> 00:32:24,520 in multi-etiology dementia. I do have a couple disclosures, 617 00:32:24,520 --> 00:32:27,200 I've done some consultation for a couple of companies 618 00:32:27,200 --> 00:32:29,960 and I lead some clinical trials 619 00:32:29,960 --> 00:32:34,720 as site PI for a number of different companies. 620 00:32:34,720 --> 00:32:37,520 Next. 621 00:32:37,520 --> 00:32:40,200 So this recommendation, recommendation three, 622 00:32:40,200 --> 00:32:42,600 is about moving forward, 623 00:32:42,600 --> 00:32:44,400 clinical and translational research 624 00:32:44,400 --> 00:32:47,800 as opposed to basic science which we'll hear about next. 625 00:32:47,800 --> 00:32:49,520 But clinical and translational research 626 00:32:49,520 --> 00:32:54,640 focused on identifying the multi-etiologies of dementia 627 00:32:54,640 --> 00:32:59,120 in diverse populations. Next slide. 628 00:32:59,120 --> 00:33:03,720 So, we know and we're, I believe the field is really beginning 629 00:33:03,720 --> 00:33:06,320 to embrace this idea of heterogeneity 630 00:33:06,320 --> 00:33:09,640 of Alzheimer's and dementia, as a multi-etiology dementia 631 00:33:09,640 --> 00:33:11,800 which heard about it today and yesterday. 632 00:33:11,800 --> 00:33:13,360 But we know there's multiple interacting 633 00:33:13,360 --> 00:33:15,360 and co-occurring pathologies. 634 00:33:15,360 --> 00:33:19,960 These are the classic ones we look at. Next. 635 00:33:19,960 --> 00:33:24,400 This study here from the Rush Group from 2013 636 00:33:24,400 --> 00:33:27,080 reminds us that we can't really see 637 00:33:27,080 --> 00:33:28,880 and count everything that's related 638 00:33:28,880 --> 00:33:32,240 to the common neurodegenerative pathology, 639 00:33:32,240 --> 00:33:35,360 or actually late life cognitive decline. 640 00:33:35,360 --> 00:33:38,960 So this study identified about 41% of the variants 641 00:33:38,960 --> 00:33:40,600 that explains the late life 642 00:33:40,600 --> 00:33:44,000 cognitive decline through pathology. 643 00:33:44,000 --> 00:33:49,280 But, what remains is about 60% of the variants of late life 644 00:33:49,280 --> 00:33:52,160 cognitive decline that's unexplained by these, 645 00:33:52,160 --> 00:33:54,440 you know, more common neurodegenerative pathologies. 646 00:33:54,440 --> 00:33:56,200 It reminds us we really can't see 647 00:33:56,200 --> 00:33:58,200 and count everything that's related 648 00:33:58,200 --> 00:34:01,240 to these late life dementia's. 649 00:34:01,240 --> 00:34:05,760 Next slide. And go ahead again. 650 00:34:05,760 --> 00:34:11,000 And another study from the same group in 2019 on individuals 651 00:34:11,000 --> 00:34:13,840 who are diagnosed with Alzheimer's Disease 652 00:34:13,840 --> 00:34:16,200 clinically found that really the, 653 00:34:16,200 --> 00:34:18,600 from a neuropathological perspective, 654 00:34:18,600 --> 00:34:20,280 these dementia's can be attributed 655 00:34:20,280 --> 00:34:25,000 to a variety of common neuropathologies. 656 00:34:25,000 --> 00:34:28,400 So, reminding us that when we think it's Alzheimer's, 657 00:34:28,400 --> 00:34:30,760 that the things that we can count are multiple 658 00:34:30,760 --> 00:34:32,240 and overlapping. 659 00:34:32,240 --> 00:34:35,480 And hence the need for thinking about dementia 660 00:34:35,480 --> 00:34:40,680 in these broader terms in multi-etiologies. Next. 661 00:34:40,680 --> 00:34:44,120 So, back to the recommendation of, you know, 662 00:34:44,120 --> 00:34:46,920 how do we identify these multi-etiologies of dementia 663 00:34:46,920 --> 00:34:48,400 in diverse populations? 664 00:34:48,400 --> 00:34:50,320 My recommendation is to really promote 665 00:34:50,320 --> 00:34:52,560 and grow the observational studies 666 00:34:52,560 --> 00:34:56,920 that include multi-modal, deep phenotyping. 667 00:34:56,920 --> 00:34:58,600 So that we can begin to understand, 668 00:34:58,600 --> 00:35:02,960 better understand clinical phenotypes and biomarkers 669 00:35:02,960 --> 00:35:07,560 and how those predict and relate to the neuropathologies 670 00:35:07,560 --> 00:35:10,240 and combinations of neuropathologies. 671 00:35:10,240 --> 00:35:14,480 We need to identify risk factors for these pathologies, 672 00:35:14,480 --> 00:35:19,040 prevalence estimates and how sex and genetic factors relate. 673 00:35:19,040 --> 00:35:22,320 And importantly we need to understand the life course. 674 00:35:22,320 --> 00:35:25,800 Including social determinants of health, 675 00:35:25,800 --> 00:35:27,200 and I'll talk about that more in a second, 676 00:35:27,200 --> 00:35:30,600 but, we need to focus also on populations 677 00:35:30,600 --> 00:35:33,440 most at risk for Alzheimer's Disease and related dementia's, 678 00:35:33,440 --> 00:35:36,000 including as we've heard already this morning racial 679 00:35:36,000 --> 00:35:39,680 and ethnic minorities that appear to be more at risk. 680 00:35:39,680 --> 00:35:42,560 And groups such as Downs Syndrome. 681 00:35:42,560 --> 00:35:45,000 Next slide. 682 00:35:45,000 --> 00:35:49,000 So, we need to, we need to build this idea out more as well, 683 00:35:49,000 --> 00:35:51,200 this life course model of dementia. 684 00:35:51,200 --> 00:35:53,440 So this came from the Lancet Commissions 685 00:35:53,440 --> 00:35:56,200 Report in 2020 on dementia prevention, 686 00:35:56,200 --> 00:35:57,600 intervention and care. 687 00:35:57,600 --> 00:35:59,560 And focused on the 12 risk factors, 688 00:35:59,560 --> 00:36:02,920 12 strongest risk factors. 689 00:36:02,920 --> 00:36:07,560 And how they influence dementia risks across the life course. 690 00:36:07,560 --> 00:36:13,200 So that backwards s is a figure that shows the risk factors 691 00:36:13,200 --> 00:36:16,000 and their apparent roles in dementia 692 00:36:16,000 --> 00:36:17,520 risks across the life course. 693 00:36:17,520 --> 00:36:19,920 And we need to build this idea out more, 694 00:36:19,920 --> 00:36:23,080 really begin to understand better how the environment, 695 00:36:23,080 --> 00:36:24,920 how social determinants of health, 696 00:36:24,920 --> 00:36:27,600 and other factors across the lifespan 697 00:36:27,600 --> 00:36:30,120 interact with genetics and influence 698 00:36:30,120 --> 00:36:33,080 an individuals risk of developing dementia 699 00:36:33,080 --> 00:36:37,160 late in life. Next slide. 700 00:36:37,160 --> 00:36:39,800 And a reminder that it's not to early 701 00:36:39,800 --> 00:36:42,920 to begin to move these ideas into primary care, 702 00:36:42,920 --> 00:36:45,520 we just heard about that from Mike as well. 703 00:36:45,520 --> 00:36:48,760 But, and this is beginning to happen already, 704 00:36:48,760 --> 00:36:51,760 this scientific statement from the American Heart Association 705 00:36:51,760 --> 00:36:54,600 from last year was recommendations 706 00:36:54,600 --> 00:36:57,400 for how to move many of these ideas 707 00:36:57,400 --> 00:36:59,400 into primary care practice. 708 00:36:59,400 --> 00:37:02,000 And so, primary care physicians are interested 709 00:37:02,000 --> 00:37:04,320 and beginning to use these ideas in practice, 710 00:37:04,320 --> 00:37:06,000 we need to accelerate that. 711 00:37:06,000 --> 00:37:09,120 Next slide. So how do we do that? 712 00:37:09,120 --> 00:37:11,120 Well we need to continue to validate 713 00:37:11,120 --> 00:37:13,600 these multi biomarker approaches, 714 00:37:13,600 --> 00:37:16,600 really understand and validate how they predict 715 00:37:16,600 --> 00:37:19,440 and relate to these neuropathologies. 716 00:37:19,440 --> 00:37:23,400 And importantly we need to do research to understand 717 00:37:23,400 --> 00:37:25,960 how they influence clinical practice. 718 00:37:25,960 --> 00:37:29,720 What signs and symptoms best identify these etiologies. 719 00:37:29,720 --> 00:37:32,680 And are they clinically actionable? 720 00:37:32,680 --> 00:37:34,920 Can we identify and stratify, 721 00:37:34,920 --> 00:37:38,200 can we identify these factors or stratify individuals 722 00:37:38,200 --> 00:37:44,200 into risk groups to target them with disease specific therapies? 723 00:37:44,200 --> 00:37:47,880 And lastly, we need to think hard about access 724 00:37:47,880 --> 00:37:51,360 to these new diagnostics and new therapies. 725 00:37:51,360 --> 00:37:53,600 And then how do we scale them to the population 726 00:37:53,600 --> 00:37:56,200 so they reach everybody who needs them? 727 00:37:56,200 --> 00:37:59,320 We need to do this through more pragmatic trials 728 00:37:59,320 --> 00:38:03,240 and community-based trials. And we need to focus again 729 00:38:03,240 --> 00:38:05,200 as we've heard yesterday and today, 730 00:38:05,200 --> 00:38:10,000 on reducing inequities and reducing poor access 731 00:38:10,000 --> 00:38:12,960 to these new therapies and new diagnostics. 732 00:38:12,960 --> 00:38:15,520 And next slide. 733 00:38:15,520 --> 00:38:19,800 And this headline is a reminder of why we need to do that. 734 00:38:19,800 --> 00:38:22,600 We can't develop new diagnostics and new treatments 735 00:38:22,600 --> 00:38:26,480 that deepen these inequities of care. 736 00:38:26,480 --> 00:38:32,440 And last slide, just to bring it back to the big picture. 737 00:38:32,440 --> 00:38:35,440 The recommendation three, set at a priority three 738 00:38:35,440 --> 00:38:38,680 is to conduct multi-modal clinical 739 00:38:38,680 --> 00:38:41,200 and translational research that supports the identification 740 00:38:41,200 --> 00:38:45,000 of these multiple ideologies in diverse populations. 741 00:38:45,000 --> 00:38:50,120 And so now I'll turn it over to Malu Gamez Tansey 742 00:38:50,120 --> 00:38:52,800 who's going to talk about basic research in MED. 743 00:38:55,120 --> 00:38:57,120 -Thank you Jeff. 744 00:38:57,120 --> 00:39:00,320 Thank you for your time everybody. 745 00:39:00,320 --> 00:39:03,840 The focus area two for basic research in MED, 746 00:39:03,840 --> 00:39:05,400 recommendation four, 747 00:39:05,400 --> 00:39:07,720 priority two to advance basic research on a common 748 00:39:07,720 --> 00:39:11,400 and interacting risk factors and mechanisms of multiple etiology 749 00:39:11,400 --> 00:39:15,160 cognitive impairment in dementia in diverse populations. 750 00:39:15,160 --> 00:39:17,840 Was put together by contributions 751 00:39:17,840 --> 00:39:21,320 from Dr. Brad Hyman and Lea Grinberg. 752 00:39:21,320 --> 00:39:22,880 Next slide. 753 00:39:22,880 --> 00:39:25,160 You see our disclosures and there are several. 754 00:39:25,160 --> 00:39:27,720 So I won't read through them. 755 00:39:27,720 --> 00:39:30,600 We will go to the next slide and start the recommendation. 756 00:39:30,600 --> 00:39:32,840 Again, under that main recommendation 757 00:39:32,840 --> 00:39:34,840 we have four sub-recommendations. 758 00:39:34,840 --> 00:39:36,600 And they are to define the interactions 759 00:39:36,600 --> 00:39:39,240 at the molecular and cellular level of the common 760 00:39:39,240 --> 00:39:42,200 and newly identify pathobiologies of MED. 761 00:39:42,200 --> 00:39:44,000 To define the molecular signatures 762 00:39:44,000 --> 00:39:47,640 of vulnerable versus resilient neuronal populations. 763 00:39:47,640 --> 00:39:51,400 To incentivize innovation, to address technological gaps 764 00:39:51,400 --> 00:39:54,280 and to incentivize creation of multidisciplinary, 765 00:39:54,280 --> 00:39:58,000 multi-sector, multi-career stage teams 766 00:39:58,000 --> 00:39:59,920 to address both the heterogeneity 767 00:39:59,920 --> 00:40:02,360 and the common mechanism questions of MED. 768 00:40:02,360 --> 00:40:04,960 And in the next few slides I'm going to show you 769 00:40:04,960 --> 00:40:08,640 the progress towards these four sub-recommendations 770 00:40:08,640 --> 00:40:10,880 and where we still need to do more. 771 00:40:10,880 --> 00:40:14,160 So, the first thing you see is that research efforts 772 00:40:14,160 --> 00:40:17,400 to advance basic science since the 2019 summit 773 00:40:17,400 --> 00:40:21,000 have involved of course the four main proteins. 774 00:40:21,000 --> 00:40:25,080 Tau, alpha-synuclein, TDP43 and amyloid beta. 775 00:40:25,080 --> 00:40:29,120 And we know that the mechanisms of toxicity of these proteins 776 00:40:29,120 --> 00:40:32,040 involve the organization, their propagation 777 00:40:32,040 --> 00:40:34,440 and there's an, if there's an imbalance 778 00:40:34,440 --> 00:40:37,240 in the synthesis aggregation or clearance of these proteins 779 00:40:37,240 --> 00:40:39,800 in can result in chronic accumulation 780 00:40:39,800 --> 00:40:42,840 that leads to further aggregation, and propagation 781 00:40:42,840 --> 00:40:45,800 and potentially interactions with inflammation, 782 00:40:45,800 --> 00:40:47,280 eventually neurodegeneration. 783 00:40:47,280 --> 00:40:49,880 That's the model that everybody's testing. 784 00:40:49,880 --> 00:40:52,040 However, in the next slide you will see 785 00:40:52,040 --> 00:40:55,280 that it gets very complex because we see 786 00:40:55,280 --> 00:40:58,600 that they are different strains of these seeds. 787 00:40:58,600 --> 00:41:00,360 And so, in the seminal work 788 00:41:00,360 --> 00:41:03,760 by John Trojanwoski and Virginia Lee, 789 00:41:03,760 --> 00:41:05,840 where they showed that there were unique pathological 790 00:41:05,840 --> 00:41:07,800 tau conformers from brain 791 00:41:07,800 --> 00:41:10,480 that could transmit in non-transgenic mice. 792 00:41:10,480 --> 00:41:13,200 We now know from work of Michelle Goddard 793 00:41:13,200 --> 00:41:16,760 and other investigators including a review 794 00:41:16,760 --> 00:41:18,400 from Kejal Ashul 795 00:41:18,400 --> 00:41:21,360 that the complexity of these amyloid strains 796 00:41:21,360 --> 00:41:23,640 is very very high. 797 00:41:23,640 --> 00:41:26,040 And interestingly enough from the work 798 00:41:26,040 --> 00:41:30,120 of Brad Hyman and Safar's group, 799 00:41:30,120 --> 00:41:32,280 we see that this molecular diversity 800 00:41:32,280 --> 00:41:35,880 may contribute to clinical heterogeneity in AD 801 00:41:35,880 --> 00:41:39,560 and may be associated with rapidly progressing Alzheimer's. 802 00:41:39,560 --> 00:41:43,200 And so, and on the next slide what you will see is this idea 803 00:41:43,200 --> 00:41:46,040 that we may not be able to get away with 804 00:41:46,040 --> 00:41:47,640 just targeting one of these, 805 00:41:47,640 --> 00:41:50,920 we may have to think about combination immunotherapy 806 00:41:50,920 --> 00:41:53,560 and as well as targeting the inflammation 807 00:41:53,560 --> 00:41:56,480 that comes from these interactions. 808 00:41:56,480 --> 00:42:01,240 And finally there's a new kid in town and that's TM106B, 809 00:42:01,240 --> 00:42:04,760 which was recently reported by Michelle Goddard's group. 810 00:42:04,760 --> 00:42:07,920 That forms AIDS dependent amyloid filaments 811 00:42:07,920 --> 00:42:09,440 in human brain. 812 00:42:09,440 --> 00:42:12,720 And then the next slide what you will see 813 00:42:12,720 --> 00:42:14,680 and I'd like to highlight is that, 814 00:42:14,680 --> 00:42:17,960 targeting tau is not just about immunotherapy, 815 00:42:17,960 --> 00:42:20,000 there are other non-immunotherapy approaches 816 00:42:20,000 --> 00:42:24,600 such as anti-sense oligose from Tim Muller's group back in 2017 817 00:42:24,600 --> 00:42:29,120 and also from Brad Hyman's group the, a way to repress tau 818 00:42:29,120 --> 00:42:32,000 is by using zinc-finger protein nucleases 819 00:42:32,000 --> 00:42:33,480 that will, you know, 820 00:42:33,480 --> 00:42:37,640 repress the transcription and formation of tau. 821 00:42:37,640 --> 00:42:40,440 And in the next slide I'd like to highlight 822 00:42:40,440 --> 00:42:42,960 basically that one of the seminal discoveries 823 00:42:42,960 --> 00:42:46,680 since the last summit and expanded upon is, 824 00:42:46,680 --> 00:42:49,960 linking tau to immunity and lipid biology. 825 00:42:49,960 --> 00:42:53,720 Much of this work has come from the lab of David Holtzman. 826 00:42:53,720 --> 00:42:57,680 Where they tied ApoE4 to exacerbation 827 00:42:57,680 --> 00:43:01,360 of tomigated neurodegeneration in mouse models. 828 00:43:01,360 --> 00:43:04,120 Followed by linking it to interactions 829 00:43:04,120 --> 00:43:08,800 between APOE and TRIM2. And finally a very recent report 830 00:43:08,800 --> 00:43:11,160 that implicates the glymphatic system 831 00:43:11,160 --> 00:43:13,360 and that clearance of extracellular tau 832 00:43:13,360 --> 00:43:16,120 and protection again Tau aggregation. 833 00:43:16,120 --> 00:43:18,160 And then in the next slide 834 00:43:18,160 --> 00:43:21,320 I would like to highlight the fact that we know 835 00:43:21,320 --> 00:43:24,800 as well that in addition to these protein apathies 836 00:43:24,800 --> 00:43:27,680 there are incidental copathologies 837 00:43:27,680 --> 00:43:30,200 that co-occur with neurodegeneration. 838 00:43:30,200 --> 00:43:32,320 But the consequences are unknown. 839 00:43:32,320 --> 00:43:35,160 Some of these may impact cognition 840 00:43:35,160 --> 00:43:37,480 and some may protect against spread. 841 00:43:37,480 --> 00:43:40,480 So there's much work to be done in this area. 842 00:43:40,480 --> 00:43:43,880 And in the next slide we'd like to highlight 843 00:43:43,880 --> 00:43:48,400 that there's been good progress in implicating immunity 844 00:43:48,400 --> 00:43:52,480 in lipid processing with genetic loci. 845 00:43:52,480 --> 00:43:54,160 And this is important 846 00:43:54,160 --> 00:43:58,320 because all the geneticists need to have it grounded in genes 847 00:43:58,320 --> 00:44:01,480 in order to really understand that it's important. 848 00:44:01,480 --> 00:44:05,760 And so this is a good advance in my book and many other books. 849 00:44:05,760 --> 00:44:07,640 There's also the importance of the gut, 850 00:44:07,640 --> 00:44:09,600 brain microbiome access, 851 00:44:09,600 --> 00:44:12,720 where we know that there are bacteria 852 00:44:12,720 --> 00:44:15,360 that produce short-chain fatty acids 853 00:44:15,360 --> 00:44:19,880 and those may be associated with protection 854 00:44:19,880 --> 00:44:23,240 against early onset of certain forms of dementia. 855 00:44:23,240 --> 00:44:26,680 In the next slide we'd like to highlight the fact 856 00:44:26,680 --> 00:44:30,400 that there's been lots of advances in the next slide, 857 00:44:30,400 --> 00:44:36,400 in iPSCs or select vulnerability for understanding 858 00:44:36,400 --> 00:44:40,200 that in any kind of injury the cell type matters. 859 00:44:40,200 --> 00:44:42,480 Because it will, the degree of dysfunction 860 00:44:42,480 --> 00:44:45,000 depends on which cell is injured. 861 00:44:45,000 --> 00:44:48,240 And for instance excitatory neurons 862 00:44:48,240 --> 00:44:51,600 can be more prone to accumulate tau and die 863 00:44:51,600 --> 00:44:55,840 compared to, you know, other subtypes if they're, 864 00:44:55,840 --> 00:44:58,720 you know, if they're not a certain phenotype. 865 00:44:58,720 --> 00:45:01,600 And so in the next slide we also know 866 00:45:01,600 --> 00:45:06,040 that there are advances in iPSCs in the next slide. 867 00:45:06,040 --> 00:45:12,880 That have been important, but, they're limited by the fact 868 00:45:12,880 --> 00:45:16,920 that not everybody's growing them in two and 3D culture. 869 00:45:16,920 --> 00:45:23,440 And so, the phenotype is forward with iPSC work 870 00:45:23,440 --> 00:45:25,480 that they're grown in the proper environment 871 00:45:25,480 --> 00:45:28,320 so that we know that they are more closely 872 00:45:28,320 --> 00:45:30,920 recapitulating their normal allele. 873 00:45:30,920 --> 00:45:34,920 And more importantly we also need to stress that with, 874 00:45:34,920 --> 00:45:37,880 the development of iPSC lines from individuals 875 00:45:37,880 --> 00:45:39,800 with diverse genetic backgrounds 876 00:45:39,800 --> 00:45:42,360 and diverse ethnic backgrounds is needed. 877 00:45:42,360 --> 00:45:44,600 And in the next slide we need to integrate 878 00:45:44,600 --> 00:45:49,280 everything into a o-mix approach. 879 00:45:49,280 --> 00:45:51,440 So that we know the genome, the transcriptome, 880 00:45:51,440 --> 00:45:54,480 the proteome and the metabolome all come together 881 00:45:54,480 --> 00:45:57,240 into a systems biology scenario 882 00:45:57,240 --> 00:46:01,240 where team science is really the way to go. 883 00:46:01,240 --> 00:46:05,640 And so, as we integrate these various aspects of basic science 884 00:46:05,640 --> 00:46:07,880 into a holistic systems biology approach, 885 00:46:07,880 --> 00:46:12,520 we'll be able to really understand the pathogenesis 886 00:46:12,520 --> 00:46:15,760 and the pathobiology of AD and MED. 887 00:46:15,760 --> 00:46:17,120 And in the next slide, 888 00:46:17,120 --> 00:46:21,120 is an example of what some of this, 889 00:46:21,120 --> 00:46:23,400 that has occurred, like Move AD, 890 00:46:23,400 --> 00:46:26,200 is a huge partnership between NIH, 891 00:46:26,200 --> 00:46:28,200 industry, non-profit organizations involving, 892 00:46:28,200 --> 00:46:31,480 you know, lots of labs with complimentary projects. 893 00:46:31,480 --> 00:46:34,720 And importantly it builds on the open science approach 894 00:46:34,720 --> 00:46:38,240 and big data infrastructure established by the AMP AD. 895 00:46:38,240 --> 00:46:42,400 And it's a real example of science being a team sport. 896 00:46:42,400 --> 00:46:45,760 And in the next slide are just a few examples of FOAs 897 00:46:45,760 --> 00:46:48,360 that have come out since 2019. 898 00:46:48,360 --> 00:46:52,000 Especially in the bottom highlighting, 899 00:46:52,000 --> 00:46:56,280 you know, one of the centers that was funded with this FOA, 900 00:46:56,280 --> 00:47:02,440 which is the Office of Nuclear Strains in the business lab. 901 00:47:02,440 --> 00:47:05,320 As well as the more recent Center Without Walls 902 00:47:05,320 --> 00:47:08,520 to address mechanisms of degeneration in FTD. 903 00:47:08,520 --> 00:47:11,400 And in the next slide I just want to summarize 904 00:47:11,400 --> 00:47:16,600 basically what we are saying in the four sub-recommendations. 905 00:47:16,600 --> 00:47:20,400 The areas of focus are the proteinopathy, 906 00:47:20,400 --> 00:47:23,280 inflammaging and immuno essence interactions 907 00:47:23,280 --> 00:47:25,960 that lead to cognitive decline in diverse populations. 908 00:47:25,960 --> 00:47:27,800 And understanding those mechanisms. 909 00:47:27,800 --> 00:47:30,280 Second, understanding the mechanisms of cell 910 00:47:30,280 --> 00:47:33,400 vulnerability and resilience in diverse populations 911 00:47:33,400 --> 00:47:36,600 and how they interact with neurodegeneration. 912 00:47:36,600 --> 00:47:39,920 Third, we need to incentivize the development of iPSC lines 913 00:47:39,920 --> 00:47:42,400 in two and 3D environments and from individuals 914 00:47:42,400 --> 00:47:44,160 with diverse ethnic backgrounds. 915 00:47:44,160 --> 00:47:47,200 And finally we need to incentivize basic research 916 00:47:47,200 --> 00:47:50,360 by diverse multidisciplinary, multi-sector, 917 00:47:50,360 --> 00:47:53,840 multi-career stage individuals and teams. 918 00:47:53,840 --> 00:47:55,800 Such as the CWOS. 919 00:47:55,800 --> 00:48:02,000 And I will pass it on to Doctors Okonkwo and Doctors Possin. 920 00:48:02,000 --> 00:48:04,280 Thank you. 921 00:48:04,280 --> 00:48:08,760 -Thank you so much. That has been wonderful so far. 922 00:48:08,760 --> 00:48:11,240 So now we're going trying to focus area trade 923 00:48:11,240 --> 00:48:14,200 is focused on interventions and treatments. 924 00:48:14,200 --> 00:48:17,280 And I'm going to be delivering recommendation five. 925 00:48:17,280 --> 00:48:20,200 And Dr. Possin is going to take six. 926 00:48:20,200 --> 00:48:23,720 Next slide please. 927 00:48:23,720 --> 00:48:29,000 I have no disclosures for this talk. Next slide. 928 00:48:29,000 --> 00:48:32,600 So for this recommendation the focus as mentioned earlier 929 00:48:32,600 --> 00:48:36,000 is conducting clinical studies on approved 930 00:48:36,000 --> 00:48:38,280 or promising interventions and treatments 931 00:48:38,280 --> 00:48:41,440 to mitigate risk for cognitive decline. 932 00:48:41,440 --> 00:48:43,560 And under here we have three elements 933 00:48:43,560 --> 00:48:45,320 that you're going to be hearing more about 934 00:48:45,320 --> 00:48:47,400 in the subsequent slides. 935 00:48:47,400 --> 00:48:50,960 But, in summary the key elements are focused on conducted, 936 00:48:50,960 --> 00:48:54,120 inclusive and pragmatic clinical trials. 937 00:48:54,120 --> 00:48:55,720 Supporting the development 938 00:48:55,720 --> 00:48:58,600 of practice-based research networks. 939 00:48:58,600 --> 00:49:02,800 And develop within health risks and effectiveness of hierarchies 940 00:49:02,800 --> 00:49:06,120 in diverse populations. Next slide. 941 00:49:08,600 --> 00:49:11,800 This recommendation was first introduced 942 00:49:11,800 --> 00:49:15,680 in the last ADRD summit in 2019. 943 00:49:15,680 --> 00:49:19,240 And in the years since then the progress report 944 00:49:19,240 --> 00:49:23,960 that was shared with the scientific community in 2021 945 00:49:23,960 --> 00:49:28,200 indicated that there has been several research milestones 946 00:49:28,200 --> 00:49:30,000 that have been accomplished. 947 00:49:30,000 --> 00:49:33,240 And some of the highlights of that, 948 00:49:33,240 --> 00:49:36,840 or a focus on post-stroke vascular contributions 949 00:49:36,840 --> 00:49:38,640 to cognitive impairment and dementia 950 00:49:38,640 --> 00:49:41,800 was released as a u19. 951 00:49:41,800 --> 00:49:44,440 And consequent on that area of then, 952 00:49:44,440 --> 00:49:48,600 the diverse VCID project was initiated 953 00:49:48,600 --> 00:49:52,800 that was under still led by Angela and the colleague. 954 00:49:52,800 --> 00:49:54,680 And also as part of the accomplishment 955 00:49:54,680 --> 00:49:57,600 also the discoveries and study 956 00:49:57,600 --> 00:49:59,960 that is focused on post-stroke cognitive 957 00:49:59,960 --> 00:50:04,680 outcomes led by Natalia Rost and Steve Greenberg 958 00:50:04,680 --> 00:50:06,400 is now underway. 959 00:50:06,400 --> 00:50:10,400 So there's been remarkable progress made under this effort 960 00:50:10,400 --> 00:50:13,160 to conduct intervention studies up until now. 961 00:50:13,160 --> 00:50:14,760 Next slide please. 962 00:50:17,000 --> 00:50:20,920 And in thinking about then the, where we wanted to take this 963 00:50:20,920 --> 00:50:25,240 for the 2022 updates for this summit. 964 00:50:25,240 --> 00:50:27,400 This happened against the backdrop 965 00:50:27,400 --> 00:50:29,480 of two recent developments. 966 00:50:29,480 --> 00:50:33,520 You already saw this slide in Jeff Burns talk. 967 00:50:33,520 --> 00:50:37,000 And this is the dementia prevention reports 968 00:50:37,000 --> 00:50:38,960 from the Lancet Commission. 969 00:50:38,960 --> 00:50:44,280 And which identified some very key risk factors for dementia. 970 00:50:44,280 --> 00:50:47,360 And these risk factors then can now be understood 971 00:50:47,360 --> 00:50:50,320 as potential targets that we can hit in order 972 00:50:50,320 --> 00:50:57,000 to forestall the projected increases in dementia prevalence 973 00:50:57,000 --> 00:50:59,280 and incidents in the coming years. 974 00:50:59,280 --> 00:51:04,960 Next slide. And the second development 975 00:51:04,960 --> 00:51:09,480 is at the end of last year we received, 976 00:51:09,480 --> 00:51:13,600 well we all received an update from the National Plans 977 00:51:13,600 --> 00:51:15,480 for Addressing Alzheimer's and Disease. 978 00:51:15,480 --> 00:51:19,800 And in that update a new goal was added to the plan. 979 00:51:19,800 --> 00:51:23,400 And this goal was specific developing 980 00:51:23,400 --> 00:51:25,680 and promoting health agent 981 00:51:25,680 --> 00:51:28,520 and with this risk factors for AD. 982 00:51:28,520 --> 00:51:31,680 Which was a very interesting and exciting development 983 00:51:31,680 --> 00:51:34,760 given that the targets and for not all along 984 00:51:34,760 --> 00:51:38,120 has been to prevent AD by 2025. 985 00:51:38,120 --> 00:51:44,200 Which also is why in this 2022 version of the ADRD Summit, 986 00:51:44,200 --> 00:51:46,040 recommendation five has now been moved 987 00:51:46,040 --> 00:51:48,720 from priority two to priority one. 988 00:51:48,720 --> 00:51:50,840 Given the imminence of the deadline 989 00:51:50,840 --> 00:51:53,160 we all have of preventing AD. 990 00:51:53,160 --> 00:51:56,440 So this focus on reducing risk factors 991 00:51:56,440 --> 00:52:00,640 we believe is very timely and informed the operation 992 00:52:00,640 --> 00:52:04,320 that we took the recommendation five on interventions. 993 00:52:04,320 --> 00:52:05,920 Next slide please. 994 00:52:08,760 --> 00:52:11,720 So the first element under this recommendation five 995 00:52:11,720 --> 00:52:16,120 is the conduct of inclusive and pragmatic clinical trials. 996 00:52:16,120 --> 00:52:19,080 In settings where risk factors for cognitive decline 997 00:52:19,080 --> 00:52:24,000 can be appropriately targeted for intervention. 998 00:52:24,000 --> 00:52:28,800 A search of clinical trials that's dove, earlier days, 999 00:52:28,800 --> 00:52:35,200 reveal that in the ten years between 2001 and 2011. 1000 00:52:35,200 --> 00:52:40,000 Approximately 450 studies in dementia studies 1001 00:52:40,000 --> 00:52:43,000 that were focus on dementia. 1002 00:52:43,000 --> 00:52:48,600 None of them had the keyword pragmatic associated with them. 1003 00:52:48,600 --> 00:52:52,240 First four, ten years and there the last decade, 1004 00:52:52,240 --> 00:52:55,720 the number of intervention studies focused on dementia 1005 00:52:55,720 --> 00:53:00,320 have exploded thanks to the massive inclusion of firms 1006 00:53:00,320 --> 00:53:03,400 to ADRD studies. 1007 00:53:03,400 --> 00:53:07,160 However, of this I am more than 1,000 studies known 1008 00:53:07,160 --> 00:53:09,800 that are focused on dementia, 1009 00:53:09,800 --> 00:53:13,600 only 25 of them have the word pragmatic 1010 00:53:13,600 --> 00:53:16,480 and attached to them as a keyword. 1011 00:53:16,480 --> 00:53:20,960 So obviously in this were some progress has been made 1012 00:53:20,960 --> 00:53:23,320 in a greater recognition 1013 00:53:23,320 --> 00:53:25,920 for the need for cognitive clinical trials. 1014 00:53:25,920 --> 00:53:31,320 And there is still a lag and opportunities for the field 1015 00:53:31,320 --> 00:53:33,080 to begin to think more in terms 1016 00:53:33,080 --> 00:53:35,400 of conducting studies in the settings 1017 00:53:35,400 --> 00:53:37,920 where the people who actually are going to be 1018 00:53:37,920 --> 00:53:41,000 impacted the most by these trials. 1019 00:53:41,000 --> 00:53:45,280 Actually are look at where they live, work and play. 1020 00:53:45,280 --> 00:53:47,200 However though, 1021 00:53:47,200 --> 00:53:50,320 despite that it's also important to underscore 1022 00:53:50,320 --> 00:53:53,840 the progress has continued to be made. 1023 00:53:53,840 --> 00:53:57,400 And on this slide we highlight some of the big studies 1024 00:53:57,400 --> 00:53:59,400 that have been, 1025 00:53:59,400 --> 00:54:02,960 that are currently occurring or have been underway 1026 00:54:02,960 --> 00:54:07,400 in the last decade in the area of both pharmacological 1027 00:54:07,400 --> 00:54:09,080 and non-pharmacological treatments 1028 00:54:09,080 --> 00:54:12,600 and interventions for ADRDs. 1029 00:54:12,600 --> 00:54:15,680 We highlight the A4 and the head studies. 1030 00:54:15,680 --> 00:54:19,640 Which are anti-angular therapies focused on individuals 1031 00:54:19,640 --> 00:54:23,000 who currently are cognitively unimpaired. 1032 00:54:23,000 --> 00:54:26,200 We also highlight the Hope for MCI study. 1033 00:54:26,200 --> 00:54:31,080 Which as the name indicates is focused on individuals with MCI. 1034 00:54:31,080 --> 00:54:33,320 And this study is focused 1035 00:54:33,320 --> 00:54:37,880 on addressing people hypocampal, hyperactivation. 1036 00:54:37,880 --> 00:54:41,360 And then the Libit Study that is focused on individuals 1037 00:54:41,360 --> 00:54:44,240 in the dementia stage of the disease. 1038 00:54:44,240 --> 00:54:48,800 And this target is to understand the role that CBD and THC 1039 00:54:48,800 --> 00:54:53,480 might play in the present agitation in dementia. 1040 00:54:53,480 --> 00:54:55,680 For the non-pharmacological treatments 1041 00:54:55,680 --> 00:54:58,960 we highlight the exert study, the mind study, 1042 00:54:58,960 --> 00:55:02,920 the achieve study and the US Plan Study. 1043 00:55:02,920 --> 00:55:07,480 And we think that the non-pharmacological treatments 1044 00:55:07,480 --> 00:55:10,880 help make more progress in beginning to think 1045 00:55:10,880 --> 00:55:15,880 about how soon interventions within communities 1046 00:55:15,880 --> 00:55:17,680 that actually are going to be impacted 1047 00:55:17,680 --> 00:55:19,680 by the outcomes of this study. 1048 00:55:19,680 --> 00:55:24,240 For example the exert study and the US Plan Study 1049 00:55:24,240 --> 00:55:29,080 partnered with community-based organizations like the YMCAs 1050 00:55:29,080 --> 00:55:32,000 to actually conduct the intervention pieces 1051 00:55:32,000 --> 00:55:33,880 of the studies within the community 1052 00:55:33,880 --> 00:55:36,000 where individuals are located. 1053 00:55:36,000 --> 00:55:38,800 So the exert study is an exercise study, 1054 00:55:38,800 --> 00:55:41,440 the mind study is focused on diet, 1055 00:55:41,440 --> 00:55:45,800 the achieve study is focused on treating hearing loss 1056 00:55:45,800 --> 00:55:50,240 and the US Plan Study is a multi-domain study 1057 00:55:50,240 --> 00:55:54,800 that includes exercise, diets, cognitive stimulation 1058 00:55:54,800 --> 00:55:58,480 and also health coaching. Next slide. 1059 00:56:01,000 --> 00:56:04,000 The second element of recommendation five 1060 00:56:04,000 --> 00:56:06,240 is focused on supporting the development 1061 00:56:06,240 --> 00:56:08,960 of practice-based research networks. 1062 00:56:08,960 --> 00:56:12,120 To facilitate a translation of effective assessment 1063 00:56:12,120 --> 00:56:16,520 and intervention strategies into practice at a large scale. 1064 00:56:16,520 --> 00:56:19,200 And we think that this is truly a place where the NIA 1065 00:56:19,200 --> 00:56:24,520 and the NDS has made tremendous, tremendous progress. 1066 00:56:24,520 --> 00:56:26,400 As you can see that there are now 1067 00:56:26,400 --> 00:56:31,920 a number of versioning practice-based research networks 1068 00:56:31,920 --> 00:56:36,440 that have been developed to support the conduct 1069 00:56:36,440 --> 00:56:39,200 of pragmatic clinical trials 1070 00:56:39,200 --> 00:56:42,920 and other community-based type studies. 1071 00:56:42,920 --> 00:56:45,600 On this slide you will see that we have also highlighted 1072 00:56:45,600 --> 00:56:49,120 the NIA Intramural Center for Alzheimer's 1073 00:56:49,120 --> 00:56:52,880 and Related Dementia's, CARD. 1074 00:56:52,880 --> 00:56:55,840 CARD as you may know is the NINDS, 1075 00:56:55,840 --> 00:56:59,760 NIA crown jewel if I may use that word. 1076 00:56:59,760 --> 00:57:03,200 But currently it is focused 1077 00:57:03,200 --> 00:57:07,320 on the conduct of basic science and data science. 1078 00:57:07,320 --> 00:57:11,440 We would like to suggest that CARD is uniquely positioned 1079 00:57:11,440 --> 00:57:15,480 for serving as a hub for intervention studies. 1080 00:57:15,480 --> 00:57:17,160 Perhaps in partnerships 1081 00:57:17,160 --> 00:57:20,400 with practice-based research networks. 1082 00:57:20,400 --> 00:57:23,640 Next slide please. 1083 00:57:23,640 --> 00:57:26,760 And then the last element of this recommendation five 1084 00:57:26,760 --> 00:57:32,840 is to evaluate health risks and effectiveness of AD therapies. 1085 00:57:32,840 --> 00:57:35,240 Such as anti-amyloid therapies 1086 00:57:35,240 --> 00:57:37,720 and more patients from diverse culture 1087 00:57:37,720 --> 00:57:41,120 and socioeconomic backgrounds. 1088 00:57:41,120 --> 00:57:44,640 The topic of inclusion and equity 1089 00:57:44,640 --> 00:57:49,000 was the focus of an entire session yesterday. 1090 00:57:49,000 --> 00:57:50,720 And we already have heard a lot 1091 00:57:50,720 --> 00:57:53,000 about it this morning from my colleagues. 1092 00:57:53,000 --> 00:57:59,120 But just in highlight form, we all understand and appreciate 1093 00:57:59,120 --> 00:58:04,120 that ADRD more prevalent in minoritized groups. 1094 00:58:04,120 --> 00:58:09,800 However, a recent survey in 2020 of nine 1095 00:58:09,800 --> 00:58:13,800 of the large scale observational 1096 00:58:13,800 --> 00:58:17,400 and clinical studies in the ADRD field 1097 00:58:17,400 --> 00:58:21,480 indicated that the vast majority of participants 1098 00:58:21,480 --> 00:58:25,920 who enrolled in these studies are not Hispanic whites. 1099 00:58:25,920 --> 00:58:30,520 More recently a few months ago, another survey that this focused 1100 00:58:30,520 --> 00:58:33,760 on drug trials in the ADRD space, 1101 00:58:33,760 --> 00:58:39,880 indicated that about 95% of all the participants 1102 00:58:39,880 --> 00:58:44,480 in these studies again were not Hispanic whites. 1103 00:58:44,480 --> 00:58:46,960 So I think, you know, it is certainly obvious to say 1104 00:58:46,960 --> 00:58:51,200 that this statistical is no longer tenable. 1105 00:58:51,200 --> 00:58:55,920 And the field has a moral and ethical impurity 1106 00:58:55,920 --> 00:59:00,440 to begin to move the middle. Next slide please. 1107 00:59:00,440 --> 00:59:03,600 And again, you know, this is now reflected in some book 1108 00:59:03,600 --> 00:59:07,800 lay and scientific articles like the one by Jan Manley 1109 00:59:07,800 --> 00:59:09,520 and her colleague. 1110 00:59:09,520 --> 00:59:12,800 Addressing the, and developments in lab 1111 00:59:12,800 --> 00:59:18,800 and how the lack of diversity in the patient group 1112 00:59:18,800 --> 00:59:21,440 is something that needs to become to new to be explored 1113 00:59:21,440 --> 00:59:23,560 as this trial, as this drug move 1114 00:59:23,560 --> 00:59:29,000 towards further community and developments. 1115 00:59:29,000 --> 00:59:34,720 Next slide please. So what then are our next steps? 1116 00:59:34,720 --> 00:59:38,040 And I want to focus on the three key elements 1117 00:59:38,040 --> 00:59:40,400 on this recommendation. 1118 00:59:40,400 --> 00:59:42,400 The first one being intervention. 1119 00:59:42,400 --> 00:59:46,400 We want to call attention that there is need to look 1120 00:59:46,400 --> 00:59:50,480 at the settings in which these studies are being conducted. 1121 00:59:50,480 --> 00:59:54,600 And also the modalities and the majority of studies in, 1122 00:59:54,600 --> 00:59:57,080 are still single modality studies. 1123 00:59:57,080 --> 01:00:01,200 But as you heard, you know, in Jeff Burns talk, 1124 01:00:01,200 --> 01:00:04,800 you know, it is the rare occasion 1125 01:00:04,800 --> 01:00:07,640 that an individual with AD at autopsy 1126 01:00:07,640 --> 01:00:12,800 only has AD as a neuropathology. So want to begin to think more 1127 01:00:12,800 --> 01:00:16,320 in terms of more multi-modal studies. 1128 01:00:16,320 --> 01:00:18,800 Also in terms of targets, 1129 01:00:18,800 --> 01:00:24,520 the most prevalence and hierarchies studies for ADRD 1130 01:00:24,520 --> 01:00:28,800 are at this point focused on anti-amyloid. 1131 01:00:28,800 --> 01:00:32,720 And we want to highlight that it is time for the field 1132 01:00:32,720 --> 01:00:35,080 to begin to pay more specific attention 1133 01:00:35,080 --> 01:00:37,560 to the other part of it physiologist 1134 01:00:37,560 --> 01:00:39,800 that underlie ADRDs. 1135 01:00:39,800 --> 01:00:41,720 And that's the different populations of interest 1136 01:00:41,720 --> 01:00:45,400 is an area to consider. 1137 01:00:45,400 --> 01:00:49,640 We want to highlight the need to expand the spectrum 1138 01:00:49,640 --> 01:00:53,200 from individuals who are cognitively unimpaired, 1139 01:00:53,200 --> 01:00:57,040 all the way to individuals who have dementia. 1140 01:00:57,040 --> 01:01:01,880 In terms of infrastructure we believe that there is a need 1141 01:01:01,880 --> 01:01:05,760 not only for an increased development of PBRNs, 1142 01:01:05,760 --> 01:01:08,080 the practice-based research networks, 1143 01:01:08,080 --> 01:01:12,080 but also for an increased use of those networks. 1144 01:01:12,080 --> 01:01:15,160 Because it is critical that as disparities 1145 01:01:15,160 --> 01:01:17,200 and interventions are being developed, 1146 01:01:17,200 --> 01:01:19,400 that they are housed within the areas 1147 01:01:19,400 --> 01:01:22,080 where the people who are going to be 1148 01:01:22,080 --> 01:01:25,160 using the outcomes of these studies where they live, 1149 01:01:25,160 --> 01:01:27,240 work and play. 1150 01:01:27,240 --> 01:01:29,480 And finally, you know, we think that there is a need 1151 01:01:29,480 --> 01:01:34,200 to continue to pay attention to issues of representation. 1152 01:01:34,200 --> 01:01:37,640 And this is going to require us to be very critical 1153 01:01:37,640 --> 01:01:41,200 of the inclusion and exclusion criteria. 1154 01:01:41,200 --> 01:01:43,400 That we implement in these studies. 1155 01:01:43,400 --> 01:01:45,280 Because that is actually the first place 1156 01:01:45,280 --> 01:01:47,800 that we begin to exclude individuals 1157 01:01:47,800 --> 01:01:52,680 who actually are most affected by these diseases. 1158 01:01:52,680 --> 01:01:58,080 I want to leave you then with some resources in terms of 1159 01:01:58,080 --> 01:02:01,440 funding opportunities that people can apply 1160 01:02:01,440 --> 01:02:04,960 for in order to begin to propose interventions. 1161 01:02:04,960 --> 01:02:08,680 Both from a pharmacological and non-pharmacological ones. 1162 01:02:08,680 --> 01:02:11,120 And we want to call specific attention 1163 01:02:11,120 --> 01:02:14,080 to the very last bullet there. 1164 01:02:14,080 --> 01:02:18,840 The request for information on capacity and support. 1165 01:02:18,840 --> 01:02:23,360 That the NIH, sorry that the NIA has released to receive 1166 01:02:23,360 --> 01:02:27,960 information from the community in terms of how the NIA 1167 01:02:27,960 --> 01:02:31,680 can build some community-based research networks. 1168 01:02:31,680 --> 01:02:34,800 To increase the participation of diverse groups 1169 01:02:34,800 --> 01:02:37,640 in ADRD clinical trials. 1170 01:02:37,640 --> 01:02:39,600 And I believe that is my last slide 1171 01:02:39,600 --> 01:02:43,200 and I'd like to hand it off now to my colleague Dr. Kate Possin. 1172 01:02:43,200 --> 01:02:46,440 Thank you. 1173 01:02:46,440 --> 01:02:48,880 -Okay thank you so much. 1174 01:02:48,880 --> 01:02:52,560 Great, so I'm going to be presenting recommendation six. 1175 01:02:52,560 --> 01:02:55,640 Which is to implement and evaluate outcomes 1176 01:02:55,640 --> 01:02:57,880 for effective dementia care programs 1177 01:02:57,880 --> 01:03:01,560 that support persons living with dementia and their caregivers. 1178 01:03:01,560 --> 01:03:03,000 Including those of socially, 1179 01:03:03,000 --> 01:03:06,120 ethnically and racially diverse populations. 1180 01:03:06,120 --> 01:03:10,440 This recommendation includes advancing research 1181 01:03:10,440 --> 01:03:12,840 to identify barriers and facilitators 1182 01:03:12,840 --> 01:03:17,120 to widespread diffusion of promising interventions, 1183 01:03:17,120 --> 01:03:19,200 conducting implementation studies, 1184 01:03:19,200 --> 01:03:22,520 developing and evaluating payment models and developing 1185 01:03:22,520 --> 01:03:25,800 and evaluating core components of culturally sensitive 1186 01:03:25,800 --> 01:03:27,880 collaborative dementia care models, 1187 01:03:27,880 --> 01:03:31,360 that deliver high quality care. Next. 1188 01:03:31,360 --> 01:03:35,000 So I'll start by setting the context 1189 01:03:35,000 --> 01:03:38,080 for this recommendation with a quote from Julia, 1190 01:03:38,080 --> 01:03:41,800 a person living with early stage Alzheimer's Disease. 1191 01:03:41,800 --> 01:03:47,280 It took us nearly four years to get a diagnosis. 1192 01:03:47,280 --> 01:03:49,960 The doctor told us it was Alzheimer's, 1193 01:03:49,960 --> 01:03:51,440 that there was nothing he could do 1194 01:03:51,440 --> 01:03:53,240 and to come back in a year. 1195 01:03:53,240 --> 01:03:55,960 We were first devastated then angry. 1196 01:03:55,960 --> 01:03:59,160 I also have diabetes, I got medication, education 1197 01:03:59,160 --> 01:04:01,400 and care management for that. 1198 01:04:01,400 --> 01:04:07,920 Now I have a fatal brain disease and I got diagnosed and adios. 1199 01:04:07,920 --> 01:04:09,560 We have to do better. 1200 01:04:11,600 --> 01:04:14,200 So we, those of you who were at the health equity session 1201 01:04:14,200 --> 01:04:16,280 yesterday also heard from Mr. Lacina 1202 01:04:16,280 --> 01:04:17,960 during the question and answer period, 1203 01:04:17,960 --> 01:04:20,480 a caregiver who highlighted the importance 1204 01:04:20,480 --> 01:04:23,720 of transparent disclosure of diagnosis. 1205 01:04:23,720 --> 01:04:27,400 And prognosis and of guiding caregivers into their role. 1206 01:04:27,400 --> 01:04:30,680 And we started today with those poignant inspirational videos 1207 01:04:30,680 --> 01:04:33,120 of people living with dementia and their caregivers. 1208 01:04:33,120 --> 01:04:34,600 That also highlighted the importance 1209 01:04:34,600 --> 01:04:36,600 of supporting the caregiver. 1210 01:04:36,600 --> 01:04:39,000 Planning ahead, getting affairs in order 1211 01:04:39,000 --> 01:04:42,400 and focusing on well-being. Next. 1212 01:04:42,400 --> 01:04:48,000 Yet dementia care is too often crisis oriented and fragmented. 1213 01:04:48,000 --> 01:04:51,760 Frequent emergency department visits and hospitalizations, 1214 01:04:51,760 --> 01:04:55,000 multiple care transitions, inappropriate 1215 01:04:55,000 --> 01:04:58,280 and potentially harmful medication use. 1216 01:04:58,280 --> 01:05:01,120 Patients experience aggressive end of life care 1217 01:05:01,120 --> 01:05:05,680 that's often inconsistent with their values and expensive. 1218 01:05:05,680 --> 01:05:08,360 Informal caregivers shoulder substantial burdens 1219 01:05:08,360 --> 01:05:09,680 with minimal support 1220 01:05:09,680 --> 01:05:13,560 from our patient-centric healthcare models. 1221 01:05:13,560 --> 01:05:15,360 And when caregivers are depressed, 1222 01:05:15,360 --> 01:05:19,480 people living with dementia use the emergency department more. 1223 01:05:19,480 --> 01:05:22,880 The COVID-19 pandemic has disproportionately disrupted 1224 01:05:22,880 --> 01:05:27,120 the lives of people living with dementia and their caregivers. 1225 01:05:27,120 --> 01:05:30,640 Next. 1226 01:05:30,640 --> 01:05:34,880 In 2019 this ADRD specific milestone 1227 01:05:34,880 --> 01:05:38,200 was given two success criteria. 1228 01:05:38,200 --> 01:05:40,360 They were, to write a white paper 1229 01:05:40,360 --> 01:05:43,040 on proven dementia care programs. 1230 01:05:43,040 --> 01:05:45,680 That effectively support persons with dementia 1231 01:05:45,680 --> 01:05:47,520 and their caregivers. 1232 01:05:47,520 --> 01:05:50,680 And to establish a national consortium 1233 01:05:50,680 --> 01:05:52,280 tasked with applied research 1234 01:05:52,280 --> 01:05:55,640 to determine how to implement widely across the country 1235 01:05:55,640 --> 01:05:59,720 in everyday care settings, proving care programs. 1236 01:05:59,720 --> 01:06:02,600 The first of these milestones has been completed 1237 01:06:02,600 --> 01:06:06,040 and I will now share the results. Next. 1238 01:06:06,040 --> 01:06:10,720 A systematic review of dementia care models was produced by AHRQ 1239 01:06:10,720 --> 01:06:13,160 at the request of NIA. 1240 01:06:13,160 --> 01:06:17,840 And this review evaluated the evidence that care models were, 1241 01:06:17,840 --> 01:06:19,440 that which care models were ready 1242 01:06:19,440 --> 01:06:22,520 for broad dissemination and implementation. 1243 01:06:22,520 --> 01:06:25,600 This report was followed by a consensus study report 1244 01:06:25,600 --> 01:06:27,560 by the National Academy's of Science, 1245 01:06:27,560 --> 01:06:29,760 Engineering and Medicine. 1246 01:06:29,760 --> 01:06:32,760 Together these reports provide a helpful overview 1247 01:06:32,760 --> 01:06:34,760 of the evidence landscape. 1248 01:06:34,760 --> 01:06:37,680 And they concluded that evidence is sufficient 1249 01:06:37,680 --> 01:06:41,880 to justify implementation of two types of interventions 1250 01:06:41,880 --> 01:06:45,360 in a broad spectrum of community settings with evaluation 1251 01:06:45,360 --> 01:06:49,520 conducted to continue expanding the evidence-base. 1252 01:06:49,520 --> 01:06:52,320 These are collaborative care models 1253 01:06:52,320 --> 01:06:56,800 and multi-component caregiver support. Next. 1254 01:06:56,800 --> 01:07:00,680 So collaborative care models use multidisciplinary teams 1255 01:07:00,680 --> 01:07:04,280 to coordinate psychosocial and medical care. 1256 01:07:04,280 --> 01:07:06,080 Typically with a care navigator, 1257 01:07:06,080 --> 01:07:10,400 or care manager as the primary point of contact for the family. 1258 01:07:10,400 --> 01:07:13,000 They emphasize the immediate needs of the person 1259 01:07:13,000 --> 01:07:15,000 living with dementia and the caregiver. 1260 01:07:15,000 --> 01:07:17,080 Often called a diad. 1261 01:07:17,080 --> 01:07:20,600 And they also prioritized proactive care planning, 1262 01:07:20,600 --> 01:07:23,360 personalized to the diad. 1263 01:07:23,360 --> 01:07:26,800 So these programs have been shown to improve quality of life 1264 01:07:26,800 --> 01:07:28,840 for the person living with dementia, 1265 01:07:28,840 --> 01:07:32,200 caregiver well-being, health system level markers, 1266 01:07:32,200 --> 01:07:35,000 including improvements in quality indicators 1267 01:07:35,000 --> 01:07:39,200 and reducing emergency room visits. Next. 1268 01:07:39,200 --> 01:07:44,760 Multi-component caregiver support provides 1269 01:07:44,760 --> 01:07:47,200 caregivers with the knowledge, skills and access 1270 01:07:47,200 --> 01:07:51,160 to resources they need to promote their own well-being 1271 01:07:51,160 --> 01:07:54,880 as well as that of the person living with dementia 1272 01:07:54,880 --> 01:07:56,680 for whom they care. 1273 01:07:56,680 --> 01:08:01,480 And outcomes improved include caregiver depression. Next. 1274 01:08:04,600 --> 01:08:06,720 So we know that collaborative care 1275 01:08:06,720 --> 01:08:10,160 and multi-component caregiver support models 1276 01:08:10,160 --> 01:08:12,840 improve outcomes for people living with dementia 1277 01:08:12,840 --> 01:08:14,120 and their families. 1278 01:08:14,120 --> 01:08:16,480 Yet these programs remain unavailable 1279 01:08:16,480 --> 01:08:20,880 to the vast majority. Scientists have a critical role 1280 01:08:20,880 --> 01:08:24,360 in bridging the science practice gap. 1281 01:08:24,360 --> 01:08:27,160 Too often scientists expect that the implementation 1282 01:08:27,160 --> 01:08:28,800 and dissemination of their interventions 1283 01:08:28,800 --> 01:08:30,800 will be taken up by other parties. 1284 01:08:30,800 --> 01:08:32,640 Which is often not the case. 1285 01:08:32,640 --> 01:08:35,200 And as scientists need to understand the barriers 1286 01:08:35,200 --> 01:08:37,880 to dissemination effective dementia care 1287 01:08:37,880 --> 01:08:41,880 and trial implementation methods to bridge the gap. 1288 01:08:41,880 --> 01:08:43,320 Next. 1289 01:08:43,320 --> 01:08:46,360 So in closing, please imagine with me 1290 01:08:46,360 --> 01:08:49,160 a near future of dementia care. 1291 01:08:49,160 --> 01:08:52,800 Imagine if every patient was a concern for cognitive decline 1292 01:08:52,800 --> 01:08:57,400 is evaluated, giving appropriate treatment, connected to care. 1293 01:08:57,400 --> 01:08:59,840 Imagine that once diagnosed with dementia 1294 01:08:59,840 --> 01:09:03,280 and their caregivers have someone in the medical system 1295 01:09:03,280 --> 01:09:06,200 who helps navigate them through the challenges 1296 01:09:06,200 --> 01:09:08,000 of living with dementia. 1297 01:09:08,000 --> 01:09:11,000 The medical system partners with caregivers, 1298 01:09:11,000 --> 01:09:13,440 prepares them for their role. 1299 01:09:13,440 --> 01:09:16,960 Tailors support to their needs and preferences. 1300 01:09:16,960 --> 01:09:19,120 Quality of life, well-being, 1301 01:09:19,120 --> 01:09:20,720 for both the person with dementia 1302 01:09:20,720 --> 01:09:24,040 and the caregiver, are made a priority. 1303 01:09:24,040 --> 01:09:27,600 We can do this. Next. 1304 01:09:27,600 --> 01:09:29,880 I would now like to introduce Heather Snyder 1305 01:09:29,880 --> 01:09:32,040 from the Alzheimer's Association. 1306 01:09:32,040 --> 01:09:37,240 Who will close our presentation with the last two focus areas. 1307 01:09:37,240 --> 01:09:39,400 -Thank you so much and hi everybody 1308 01:09:39,400 --> 01:09:41,640 and I think building on all of the presentations 1309 01:09:41,640 --> 01:09:44,600 that you've heard today, the last two focus areas 1310 01:09:44,600 --> 01:09:47,880 really are all encompassing of those recommendations. 1311 01:09:47,880 --> 01:09:50,000 Thinking about a dementia capable workforce 1312 01:09:50,000 --> 01:09:52,440 and data harmonization. Next slide. 1313 01:09:54,800 --> 01:09:57,200 In terms of my disclosures I'm a full-time employee 1314 01:09:57,200 --> 01:10:01,520 of the Alzheimer's Association. Next slide. 1315 01:10:01,520 --> 01:10:03,400 So looking at the first recommendation 1316 01:10:03,400 --> 01:10:06,600 or the first focus area, the dementia capable workforce 1317 01:10:06,600 --> 01:10:08,480 and specifically recommendation seven, 1318 01:10:08,480 --> 01:10:10,920 priority two. I'm promoting education, 1319 01:10:10,920 --> 01:10:14,600 training on multiple etiology cognitive impairment 1320 01:10:14,600 --> 01:10:17,600 and dementia to increase the dementia capable workforce. 1321 01:10:17,600 --> 01:10:20,320 Advanced researchers including from groups underrepresented 1322 01:10:20,320 --> 01:10:23,800 in science and foster includes their research practices. 1323 01:10:23,800 --> 01:10:26,880 There's a number of components within this recommendation, 1324 01:10:26,880 --> 01:10:28,960 but really to set the stage of the need 1325 01:10:28,960 --> 01:10:31,400 and we heard a little bit in the session yesterday, 1326 01:10:31,400 --> 01:10:34,240 the healthy equity session by Dr. Medina, 1327 01:10:34,240 --> 01:10:39,200 Doctors Medina and Dr. Gilsanz. The next slide. 1328 01:10:39,200 --> 01:10:42,400 In the world today the global population is aging. 1329 01:10:42,400 --> 01:10:45,040 By 2030 one in six individuals in the world 1330 01:10:45,040 --> 01:10:46,480 will be age 60 and over 1331 01:10:46,480 --> 01:10:48,800 and you can see some of the other statistics 1332 01:10:48,800 --> 01:10:50,240 that are listed here. 1333 01:10:50,240 --> 01:10:52,680 Alzheimer's Disease International estimates 1334 01:10:52,680 --> 01:10:55,800 that today there are more than 55 million individuals 1335 01:10:55,800 --> 01:10:59,040 living with dementia in the global world. 1336 01:10:59,040 --> 01:11:00,680 And the reason Facts and Figures 1337 01:11:00,680 --> 01:11:02,520 reports that there are more than six million Americans 1338 01:11:02,520 --> 01:11:04,360 that are living with Alzheimer today, 1339 01:11:04,360 --> 01:11:07,480 not to mention the full spectrum of dementia. 1340 01:11:07,480 --> 01:11:09,800 Next slide. 1341 01:11:09,800 --> 01:11:12,840 What we do look at when, in a number of different studies, 1342 01:11:12,840 --> 01:11:14,680 in a number of different reviews, 1343 01:11:14,680 --> 01:11:16,960 have looked at the dementia care specialists. 1344 01:11:16,960 --> 01:11:18,800 So those that were within the workforce 1345 01:11:18,800 --> 01:11:21,200 that are poised to provide the care and support 1346 01:11:21,200 --> 01:11:23,160 and really make that linkage of care 1347 01:11:23,160 --> 01:11:25,040 into research and back again. 1348 01:11:25,040 --> 01:11:27,360 And so whether you're looking at primary care physicians, 1349 01:11:27,360 --> 01:11:29,200 whether you're looking at geriatricians 1350 01:11:29,200 --> 01:11:31,640 or practicing geriatricians that, 1351 01:11:31,640 --> 01:11:34,240 and neurologists with dementia expertise, 1352 01:11:34,240 --> 01:11:36,760 or whether you're looking at licensed nurse practitioners 1353 01:11:36,760 --> 01:11:38,720 in the United States with either an expertise 1354 01:11:38,720 --> 01:11:40,920 in geriatric care or dementia. 1355 01:11:40,920 --> 01:11:43,400 There is a serious shortfall and this is something 1356 01:11:43,400 --> 01:11:45,000 that when we think about the workforce, 1357 01:11:45,000 --> 01:11:46,280 whether we're talking about care, 1358 01:11:46,280 --> 01:11:48,000 whether we're talking about research 1359 01:11:48,000 --> 01:11:50,120 and really the intersection of the two, 1360 01:11:50,120 --> 01:11:53,600 is certainly a gap in where we are as a community 1361 01:11:53,600 --> 01:11:56,320 and as a field. Next slide. 1362 01:11:56,320 --> 01:11:59,600 And in fact when you look at the number of states that, 1363 01:11:59,600 --> 01:12:02,840 across the country that are lacking dementia care experts, 1364 01:12:02,840 --> 01:12:05,200 or specialists, you can see that listed here 1365 01:12:05,200 --> 01:12:08,880 that the number of practicing geriatricians needs to increase 1366 01:12:08,880 --> 01:12:10,760 at least five times by 2050 1367 01:12:10,760 --> 01:12:12,640 in order to take care of the individuals 1368 01:12:12,640 --> 01:12:14,680 with Alzheimer's and other dementia. 1369 01:12:14,680 --> 01:12:18,480 And in fact 55, the recent Facts and Figures Report suggest 1370 01:12:18,480 --> 01:12:21,680 that 55% of primary care physicians 1371 01:12:21,680 --> 01:12:23,520 that are caring for individuals with Alzheimer's 1372 01:12:23,520 --> 01:12:25,080 and other dementia, 1373 01:12:25,080 --> 01:12:27,040 report that there are not enough dementia care specialists 1374 01:12:27,040 --> 01:12:29,640 in their community. Next slide. 1375 01:12:29,640 --> 01:12:32,000 So as the global prevalence of Alzheimer's 1376 01:12:32,000 --> 01:12:34,800 and other dementia increases, there is absolutely a need 1377 01:12:34,800 --> 01:12:37,920 for members of the paid dementia care workforce to increase. 1378 01:12:37,920 --> 01:12:40,400 And again, whether we're talking about those providing care, 1379 01:12:40,400 --> 01:12:42,040 or those engaging in the research, 1380 01:12:42,040 --> 01:12:45,760 and the intersection of the two, this is across the board. 1381 01:12:45,760 --> 01:12:47,600 Next slide. 1382 01:12:47,600 --> 01:12:50,400 So within the priority, or within the recommendation, 1383 01:12:50,400 --> 01:12:51,800 promoting education and training, 1384 01:12:51,800 --> 01:12:53,400 there's a number of different components. 1385 01:12:53,400 --> 01:12:55,920 And this includes developing, implementing 1386 01:12:55,920 --> 01:12:58,000 and evaluating training programs, 1387 01:12:58,000 --> 01:13:01,400 incentivizing mentorship and providing research opportunities 1388 01:13:01,400 --> 01:13:03,600 and promoting education of researchers 1389 01:13:03,600 --> 01:13:06,400 in recruiting and retaining research participants 1390 01:13:06,400 --> 01:13:10,080 from population that experience health disparities 1391 01:13:10,080 --> 01:13:11,760 in research studies. 1392 01:13:11,760 --> 01:13:15,960 So in looking at the first aspect of this in developing, 1393 01:13:15,960 --> 01:13:18,200 implementing and evaluating training programs. 1394 01:13:18,200 --> 01:13:21,200 This just gives you a snapshot of some of the training programs 1395 01:13:21,200 --> 01:13:24,240 and that are really poised 1396 01:13:24,240 --> 01:13:26,400 and are addressing some of these gaps. 1397 01:13:26,400 --> 01:13:28,400 But this is only a step in the right direction 1398 01:13:28,400 --> 01:13:31,200 and certainly as we think about the need to scale up, 1399 01:13:31,200 --> 01:13:35,600 there will be a significant need to increase and expand the scale 1400 01:13:35,600 --> 01:13:38,000 and the scope of these types of initiatives. 1401 01:13:38,000 --> 01:13:40,080 Next slide. 1402 01:13:40,080 --> 01:13:41,480 And it's really important to think about 1403 01:13:41,480 --> 01:13:43,000 as we look at the types of training's, 1404 01:13:43,000 --> 01:13:44,800 that's it not a one size fits all. 1405 01:13:44,800 --> 01:13:46,240 In fact one of the examples 1406 01:13:46,240 --> 01:13:48,640 that I shared the Global Brain Health Institute, 1407 01:13:48,640 --> 01:13:50,760 shared a quote from one of their mentors. 1408 01:13:50,760 --> 01:13:52,080 That I think the biggest strength 1409 01:13:52,080 --> 01:13:54,000 is that mentorship can be personalized. 1410 01:13:54,000 --> 01:13:55,440 Our fellows are all so different, 1411 01:13:55,440 --> 01:13:57,160 they're coming from unique backgrounds 1412 01:13:57,160 --> 01:14:00,240 and experience expertise and lived experiences. 1413 01:14:00,240 --> 01:14:02,080 So as we think about developing the types 1414 01:14:02,080 --> 01:14:03,560 of training and mentorship programs, 1415 01:14:03,560 --> 01:14:06,880 really taking this into account 1416 01:14:06,880 --> 01:14:08,800 that it's not a one size fits all. 1417 01:14:08,800 --> 01:14:10,040 And when we need to be thinking 1418 01:14:10,040 --> 01:14:11,680 about the different types of landscape 1419 01:14:11,680 --> 01:14:14,640 and the different types of programs and opportunities 1420 01:14:14,640 --> 01:14:18,480 that need to come together and support the growing workforce. 1421 01:14:18,480 --> 01:14:20,760 Next slide. 1422 01:14:20,760 --> 01:14:22,800 And a big component of this is the mentorship 1423 01:14:22,800 --> 01:14:25,320 and thinking about incentivizing mentors 1424 01:14:25,320 --> 01:14:27,200 and providing research opportunities 1425 01:14:27,200 --> 01:14:28,560 within mixed etiology, 1426 01:14:28,560 --> 01:14:31,240 dementia for the current and emerging generation. 1427 01:14:31,240 --> 01:14:33,600 We heard yesterday, I think one of the discussion items 1428 01:14:33,600 --> 01:14:35,520 was the need not only to support 1429 01:14:35,520 --> 01:14:37,440 and grow early career researchers, 1430 01:14:37,440 --> 01:14:39,800 but really think about supporting the network 1431 01:14:39,800 --> 01:14:42,400 of researchers throughout their entire career. 1432 01:14:42,400 --> 01:14:43,760 And what you see here is a listing 1433 01:14:43,760 --> 01:14:46,760 of some of the different ongoing initiatives, 1434 01:14:46,760 --> 01:14:48,000 thinking about mentorship, 1435 01:14:48,000 --> 01:14:49,440 thinking about supporting mentors 1436 01:14:49,440 --> 01:14:51,920 as well as building out mentorship programs. 1437 01:14:51,920 --> 01:14:53,960 So whether you're looking at the college age level, 1438 01:14:53,960 --> 01:14:57,160 such as the NIH funded StarU program. 1439 01:14:57,160 --> 01:15:00,880 GBHI which I mentioned, you're looking at the Interdisciplinary 1440 01:15:00,880 --> 01:15:02,920 Summer Research Institute. 1441 01:15:02,920 --> 01:15:05,360 So this is just a snapshot of organizations and groups 1442 01:15:05,360 --> 01:15:08,000 that are doing some of these programs and have initiated. 1443 01:15:08,000 --> 01:15:10,440 But again, as we think about the scope and scale 1444 01:15:10,440 --> 01:15:12,280 of what is needed to go forward, 1445 01:15:12,280 --> 01:15:15,240 we need to continue to see these programs grow. 1446 01:15:15,240 --> 01:15:17,440 As well as new programs that get to that 1447 01:15:17,440 --> 01:15:22,080 it's not a one size fits all. Next slide. 1448 01:15:22,080 --> 01:15:23,640 And so thinking about also the idea 1449 01:15:23,640 --> 01:15:25,400 of promoting education of researchers 1450 01:15:25,400 --> 01:15:29,000 and recruiting and retaining diverse research participants. 1451 01:15:29,000 --> 01:15:30,800 So throughout this entire recommendation 1452 01:15:30,800 --> 01:15:34,520 we really include activities that are promoting a conceptual 1453 01:15:34,520 --> 01:15:38,080 and theoretical perspective shaping recruitment. 1454 01:15:38,080 --> 01:15:39,400 And retention practices. 1455 01:15:39,400 --> 01:15:41,240 And building the necessary tools and again 1456 01:15:41,240 --> 01:15:43,720 you see some of those tools listed here. 1457 01:15:43,720 --> 01:15:45,280 But there are certainly others 1458 01:15:45,280 --> 01:15:48,400 that are continuing to be developed and expanded upon. 1459 01:15:48,400 --> 01:15:52,680 And continuing to build and expand these opportunities. 1460 01:15:52,680 --> 01:15:55,480 Next slide. Such as webinars, workshops, 1461 01:15:55,480 --> 01:15:57,200 and other types of training programs. 1462 01:15:57,200 --> 01:15:59,640 And again you see a snapshot of some of these here. 1463 01:15:59,640 --> 01:16:01,960 This is also an opportunity for funding organizations, 1464 01:16:01,960 --> 01:16:04,880 I know Michael J. Fox Foundation for Parkinson's Research 1465 01:16:04,880 --> 01:16:07,680 recently launched and initiated a large scale program 1466 01:16:07,680 --> 01:16:12,400 as one of those examples. Next slide. 1467 01:16:12,400 --> 01:16:15,480 So across this entire recommendation 1468 01:16:15,480 --> 01:16:16,880 you can see the full thing, 1469 01:16:16,880 --> 01:16:18,920 the full recommendation listed here. 1470 01:16:18,920 --> 01:16:20,200 There's been a number of work 1471 01:16:20,200 --> 01:16:22,000 since the original summit in 2014 1472 01:16:22,000 --> 01:16:23,520 and the continuing summits, 1473 01:16:23,520 --> 01:16:25,760 to grow and build out these educational 1474 01:16:25,760 --> 01:16:27,400 and training programs. 1475 01:16:27,400 --> 01:16:30,240 But there certainly is an opportunity to continue to scale 1476 01:16:30,240 --> 01:16:32,400 and think about, it's not a one size fits all 1477 01:16:32,400 --> 01:16:36,240 and how do we grow and expand the opportunities 1478 01:16:36,240 --> 01:16:40,040 within mixed etiology dementia? Next slide. 1479 01:16:40,040 --> 01:16:41,560 -Two minutes remaining. 1480 01:16:41,560 --> 01:16:43,880 -So thinking about the last recommendation and again 1481 01:16:43,880 --> 01:16:45,320 this all encompassing. 1482 01:16:45,320 --> 01:16:47,360 The idea to incentivize and conduct research 1483 01:16:47,360 --> 01:16:49,960 to improve pre and post-data collection harmonization 1484 01:16:49,960 --> 01:16:54,000 and sharing across multiple etiology cognitive impairment 1485 01:16:54,000 --> 01:16:56,360 and dementia studies. Next slides. 1486 01:16:56,360 --> 01:16:59,280 This includes developing and evaluating common data elements 1487 01:16:59,280 --> 01:17:01,240 and standardized consent language. 1488 01:17:01,240 --> 01:17:02,920 And again, you see a snapshot 1489 01:17:02,920 --> 01:17:04,480 of some of these ongoing initiatives. 1490 01:17:04,480 --> 01:17:07,240 Particularly focused on Mac and the uniform data set, 1491 01:17:07,240 --> 01:17:08,680 as well as the CDISK 1492 01:17:08,680 --> 01:17:11,360 and the tools that are growing and expanding. 1493 01:17:11,360 --> 01:17:12,640 But, next slide. 1494 01:17:12,640 --> 01:17:14,000 It's really important to think about 1495 01:17:14,000 --> 01:17:17,120 how we identify the barriers and facilitators 1496 01:17:17,120 --> 01:17:21,000 to incorporation of these common data elements and their usage. 1497 01:17:21,000 --> 01:17:22,800 So this could include opportunities to link 1498 01:17:22,800 --> 01:17:25,400 and share data overcoming some of these barriers. 1499 01:17:25,400 --> 01:17:28,560 Linking between some of the different data platforms, 1500 01:17:28,560 --> 01:17:30,280 including the common data elements 1501 01:17:30,280 --> 01:17:31,680 and some of the initiation studies 1502 01:17:31,680 --> 01:17:33,440 and I'll show a snapshot of some of the papers 1503 01:17:33,440 --> 01:17:38,560 that have started to do this in unique ways. Next slide. 1504 01:17:38,560 --> 01:17:42,000 And within this recommendation we also added in promotion 1505 01:17:42,000 --> 01:17:44,840 and, promoting the incorporation of common data elements 1506 01:17:44,840 --> 01:17:46,680 into data collection for observation 1507 01:17:46,680 --> 01:17:48,320 and intervention studies. 1508 01:17:48,320 --> 01:17:50,520 This is a tremendous opportunity for funding organizations, 1509 01:17:50,520 --> 01:17:52,760 whether it be NIH, or others. 1510 01:17:52,760 --> 01:17:55,760 As we look at promoting and really incentivizing 1511 01:17:55,760 --> 01:17:58,400 the incorporation of these common data elements. 1512 01:17:58,400 --> 01:18:01,560 The last component within this recommendation 1513 01:18:01,560 --> 01:18:04,160 is to develop and evaluate training opportunities 1514 01:18:04,160 --> 01:18:05,880 to promote methodological rigorous 1515 01:18:05,880 --> 01:18:08,880 in efficient data sharing. Next slide. 1516 01:18:08,880 --> 01:18:10,640 So across the board again this is a snapshot 1517 01:18:10,640 --> 01:18:12,280 of some of the different recent papers 1518 01:18:12,280 --> 01:18:15,360 that have been published, that really look at harmonizing 1519 01:18:15,360 --> 01:18:20,400 across different longitudinal studies of cognitive measures. 1520 01:18:20,400 --> 01:18:22,960 Looking at some of the considerations when we, 1521 01:18:22,960 --> 01:18:25,400 when we bring together different types of data. 1522 01:18:25,400 --> 01:18:27,320 What are some of the best practices in data sharing? 1523 01:18:27,320 --> 01:18:29,480 If you look at for instance the Cap Guidelines, 1524 01:18:29,480 --> 01:18:32,520 what are some of the initiatives and platforms such as Gain, 1525 01:18:32,520 --> 01:18:34,040 the Critical Path Institute, 1526 01:18:34,040 --> 01:18:36,000 and others that have data available 1527 01:18:36,000 --> 01:18:37,560 and that are working to cross-link 1528 01:18:37,560 --> 01:18:40,880 across these different types of platforms more broadly 1529 01:18:40,880 --> 01:18:45,920 and specifically providing an opportunity to use and to, 1530 01:18:45,920 --> 01:18:48,280 and to build upon prior work. 1531 01:18:48,280 --> 01:18:50,920 But there's also a really important component of providing 1532 01:18:50,920 --> 01:18:53,040 and developing and evaluating training opportunities 1533 01:18:53,040 --> 01:18:54,920 that promote the use of this data, 1534 01:18:54,920 --> 01:18:57,160 both the sharing of it, but also the use of it. 1535 01:18:57,160 --> 01:18:59,280 And again, that's a tremendous opportunity 1536 01:18:59,280 --> 01:19:01,360 for funding organizations. 1537 01:19:01,360 --> 01:19:03,680 So I think in summary, that brings us 1538 01:19:03,680 --> 01:19:06,680 to the multiple etiology dementia draft recommendations 1539 01:19:06,680 --> 01:19:09,120 and I think I'm passing back to Dr. Possin 1540 01:19:09,120 --> 01:19:14,320 to take us into the discussion. Kate. 1541 01:19:14,320 --> 01:19:15,720 -Thank you. 1542 01:19:15,720 --> 01:19:17,920 Thank you so much to all of our speakers today 1543 01:19:17,920 --> 01:19:19,480 and now we get to begin 1544 01:19:19,480 --> 01:19:21,960 what I hope will be a really engaging discussion. 1545 01:19:21,960 --> 01:19:25,800 We have our first question in chat from Dale Lestina, 1546 01:19:25,800 --> 01:19:29,640 so, Mr. Lestina, please ask your question. 1547 01:19:38,240 --> 01:19:41,880 -Thanks for your patience while I'm getting myself back 1548 01:19:41,880 --> 01:19:45,040 in the tune with the rest of you folks. 1549 01:19:45,040 --> 01:19:47,440 Just a minute. I got to get my picture. 1550 01:19:51,960 --> 01:19:54,640 Well, I'm tapping on it, but it doesn't come up. 1551 01:19:54,640 --> 01:20:00,400 Oh, there I am. I have a couple recommendations. 1552 01:20:00,400 --> 01:20:06,000 I applaud the presentations of this whole group. 1553 01:20:06,000 --> 01:20:14,280 And in your mind's eye when you look at the video 1554 01:20:14,280 --> 01:20:17,240 that we saw in the beginning, 1555 01:20:17,240 --> 01:20:21,800 and you saw the gentleman with his wife, 1556 01:20:21,800 --> 01:20:24,200 she's diagnosed, 1557 01:20:24,200 --> 01:20:26,240 there's two parties involved with this thing. 1558 01:20:26,240 --> 01:20:29,480 Now I would recommend 1559 01:20:29,480 --> 01:20:35,080 that if in the continuation of this presentation 1560 01:20:35,080 --> 01:20:39,800 is to show for the folks what is now about 1561 01:20:39,800 --> 01:20:46,600 to happen as time goes on with the woman or the doctor. 1562 01:20:46,600 --> 01:20:48,400 When the brain starts shutting down, 1563 01:20:48,400 --> 01:20:51,120 the ability to control bowels, 1564 01:20:51,120 --> 01:20:56,480 to control urination, to control the legs. 1565 01:20:56,480 --> 01:21:01,320 That end right there and what that does to the caregiver 1566 01:21:01,320 --> 01:21:07,200 trying to cope with this situation with a minimum, 1567 01:21:07,200 --> 01:21:11,680 if any, understanding what's going on. 1568 01:21:11,680 --> 01:21:19,280 And how to give the patient, 1569 01:21:19,280 --> 01:21:26,800 keeping that person comfortable 1570 01:21:26,800 --> 01:21:31,840 and as relaxed as possible 1571 01:21:31,840 --> 01:21:35,960 because there are periods of really hallucination 1572 01:21:35,960 --> 01:21:43,400 that they know what's going on. And how that must feel. 1573 01:21:43,400 --> 01:21:46,840 Because as you and I all know, there's no cure for this thing. 1574 01:21:46,840 --> 01:21:54,040 That's what's going to happen. And so I would say Dr. Ochen, 1575 01:21:54,040 --> 01:22:02,360 if you were involved with the continuation of that video 1576 01:22:02,360 --> 01:22:04,560 is to track it a little further 1577 01:22:04,560 --> 01:22:08,320 so that the folks who are doing the research 1578 01:22:08,320 --> 01:22:11,800 also can see what's transpiring, 1579 01:22:11,800 --> 01:22:16,600 where the rubber meets the road of the individuals 1580 01:22:16,600 --> 01:22:19,480 who are going through this. 1581 01:22:19,480 --> 01:22:26,920 It's extremely important to know all of the various things 1582 01:22:26,920 --> 01:22:30,240 that happen in the brain that causes the problem. 1583 01:22:30,240 --> 01:22:34,960 But then when you're dealing with the problem, 1584 01:22:34,960 --> 01:22:40,000 that's where I think we need to have more concentration. 1585 01:22:40,000 --> 01:22:47,400 And I would say that Kate, your presentation, 1586 01:22:47,400 --> 01:22:51,200 and your colleagues, you're the same thing, 1587 01:22:51,200 --> 01:22:54,960 I very much appreciate the recognition 1588 01:22:54,960 --> 01:23:02,680 of what is involved with this particular end of the process. 1589 01:23:02,680 --> 01:23:05,000 So that's my first recommendation 1590 01:23:05,000 --> 01:23:09,640 is to follow that now, those videos, 1591 01:23:09,640 --> 01:23:14,560 and make that as part of the presentation as well. 1592 01:23:14,560 --> 01:23:21,200 Now my second recommendation is are any of you familiar 1593 01:23:21,200 --> 01:23:26,520 with an organization called Insight? 1594 01:23:26,520 --> 01:23:29,160 I don't see any hands. Okay. 1595 01:23:29,160 --> 01:23:33,880 Insight is located, well, not too far from NIH. 1596 01:23:33,880 --> 01:23:35,400 It's in Northern Virginia. 1597 01:23:35,400 --> 01:23:39,400 It's on the west side of Fairfax City. 1598 01:23:39,400 --> 01:23:47,320 And they have -- their executive director is Anita Irvine. 1599 01:23:47,320 --> 01:23:51,680 I-R-W -- I-R-V-I-N. 1600 01:23:51,680 --> 01:23:55,760 And what they do is they treat the person 1601 01:23:55,760 --> 01:23:59,280 who has been identified with dementia, 1602 01:23:59,280 --> 01:24:02,120 and the caregiver together. 1603 01:24:02,120 --> 01:24:06,000 And they move them through a process where -- 1604 01:24:06,000 --> 01:24:12,880 sessions, where the initial diagnosis of the individual 1605 01:24:12,880 --> 01:24:17,560 who has dementia is dealt with. 1606 01:24:17,560 --> 01:24:20,640 They're dealt together, and then separately. 1607 01:24:20,640 --> 01:24:26,040 One of the things that I was fortunate enough to learn about 1608 01:24:26,040 --> 01:24:31,960 Insight is that for being a caregiver, 1609 01:24:31,960 --> 01:24:35,200 they had groups where they -- 1610 01:24:35,200 --> 01:24:39,200 support groups, where they would put me together 1611 01:24:39,200 --> 01:24:41,760 with maybe 15 other people 1612 01:24:41,760 --> 01:24:44,160 who were going through the same thing. 1613 01:24:44,160 --> 01:24:46,560 And we learned from one another. 1614 01:24:46,560 --> 01:24:48,440 "Oh, you dealt with it this way." 1615 01:24:48,440 --> 01:24:52,480 And, "Oh, that's -- I got to give that a try." 1616 01:24:52,480 --> 01:24:59,040 That kind of thing. And you have a support group 1617 01:24:59,040 --> 01:25:07,920 that after your spouse dies, continues on. 1618 01:25:07,920 --> 01:25:15,760 And I think that if you would look into that, if you want, 1619 01:25:15,760 --> 01:25:19,720 I can give you her contact information, 1620 01:25:19,720 --> 01:25:21,720 and explore what they're doing. 1621 01:25:21,720 --> 01:25:26,640 It's at least something to look at together. 1622 01:25:26,640 --> 01:25:30,400 And when you're looking at expanding things, 1623 01:25:30,400 --> 01:25:32,400 they don't want to expand too fast 1624 01:25:32,400 --> 01:25:36,160 because they want to keep doing a good job. 1625 01:25:36,160 --> 01:25:39,560 And they're just now beginning their second office 1626 01:25:39,560 --> 01:25:46,680 that they're about to expand to. So thank you for your attention 1627 01:25:46,680 --> 01:25:52,400 and listening to what I would recommend, 1628 01:25:52,400 --> 01:25:56,200 and having been a fellow who's gone through it 1629 01:25:56,200 --> 01:25:58,800 from a caregiver's point of view. 1630 01:25:58,800 --> 01:26:02,760 I appreciate your kind attention. Thank you. 1631 01:26:02,760 --> 01:26:04,280 -Thank you, Mr. Lastina. 1632 01:26:04,280 --> 01:26:09,520 Your comments are really important to our committee, 1633 01:26:09,520 --> 01:26:12,280 and we will definitely make note 1634 01:26:12,280 --> 01:26:14,200 of both of these recommendations. 1635 01:26:14,200 --> 01:26:17,080 And I personally will into the Insight program as well. 1636 01:26:17,080 --> 01:26:22,160 So thank you for those recommendations. 1637 01:26:22,160 --> 01:26:23,600 -Thank you. 1638 01:26:23,600 --> 01:26:29,560 -So let's see, next I believe is Penny Dacks. 1639 01:26:29,560 --> 01:26:30,760 -Thank you, Dr. Christine. 1640 01:26:30,760 --> 01:26:32,640 I actually want to defer to Ian first 1641 01:26:32,640 --> 01:26:34,120 because I think he had his name in first. 1642 01:26:34,120 --> 01:26:37,840 So -- -Okay. Let's do that. 1643 01:26:37,840 --> 01:26:39,400 Ian Kremer? 1644 01:26:39,400 --> 01:26:40,760 -Hi there, everyone. 1645 01:26:40,760 --> 01:26:42,920 Penny, thank you. Very kind of you. 1646 01:26:42,920 --> 01:26:44,360 Hi, everyone. I'm Ian Kremer. 1647 01:26:44,360 --> 01:26:46,200 I'm executive director of the LEAD Coalition. 1648 01:26:46,200 --> 01:26:49,000 We're a coalition of 100-member organization, 1649 01:26:49,000 --> 01:26:51,520 so about another 100 allied organizations 1650 01:26:51,520 --> 01:26:56,800 doing Alzheimer's and related dementias advocacy at the level. 1651 01:26:56,800 --> 01:26:58,680 I have a couple of recommendations. 1652 01:26:58,680 --> 01:27:00,160 I just want to preface it by saying 1653 01:27:00,160 --> 01:27:02,640 that I've had the pleasure of serving 1654 01:27:02,640 --> 01:27:06,480 on the steering committee for NIH's two Dementia Care 1655 01:27:06,480 --> 01:27:08,560 and Services Research Summits. 1656 01:27:08,560 --> 01:27:12,120 In those summits, we did not, for a variety of reasons 1657 01:27:12,120 --> 01:27:14,080 that I probably shouldn't get into today, 1658 01:27:14,080 --> 01:27:18,040 we didn't have bandwidth to get into detection and diagnosis 1659 01:27:18,040 --> 01:27:21,880 in the level of depth that we all would have liked to. 1660 01:27:21,880 --> 01:27:24,120 And that so that's still on our agenda 1661 01:27:24,120 --> 01:27:26,800 for subsequent care and services research summits, 1662 01:27:26,800 --> 01:27:30,360 but I'm delighted that you have taken time today 1663 01:27:30,360 --> 01:27:33,000 on your agenda to dive into this. 1664 01:27:33,000 --> 01:27:34,400 And I want to commend you all 1665 01:27:34,400 --> 01:27:36,960 for remarkably strong presentations 1666 01:27:36,960 --> 01:27:38,840 that get at the heart of much 1667 01:27:38,840 --> 01:27:42,280 of what makes detection and diagnosis so challenging. 1668 01:27:42,280 --> 01:27:46,120 Nobody can be comprehensive about that in any one session, 1669 01:27:46,120 --> 01:27:48,160 but you've all done a remarkable job. 1670 01:27:48,160 --> 01:27:51,040 So that's the context for what will follow, 1671 01:27:51,040 --> 01:27:54,360 which is maybe a recommendation or two. 1672 01:27:54,360 --> 01:27:58,200 I think there are opportunities for collaborative 1673 01:27:58,200 --> 01:28:03,800 funding agreements between NINDS, and NIA, 1674 01:28:03,800 --> 01:28:08,360 particularly BSR at NIA, around the psychological aspects 1675 01:28:08,360 --> 01:28:12,160 necessary to support effective detection and diagnosis. 1676 01:28:12,160 --> 01:28:15,200 And to walk you through that as briefly as I can, 1677 01:28:15,200 --> 01:28:18,560 I'll just make a few points. 1678 01:28:18,560 --> 01:28:20,960 I've advocated for about a decade work 1679 01:28:20,960 --> 01:28:22,560 for an informal framework, 1680 01:28:22,560 --> 01:28:25,800 a framework that I informally called TACA, T-A-C-A. 1681 01:28:25,800 --> 01:28:27,680 And that is that the detection and diagnosis 1682 01:28:27,680 --> 01:28:31,880 should be timely, accurate, compassionate, and actionable. 1683 01:28:31,880 --> 01:28:34,000 T-A-C-A. 1684 01:28:34,000 --> 01:28:36,280 I think you all today have addressed 1685 01:28:36,280 --> 01:28:40,280 remarkably well the need for detection and diagnosis 1686 01:28:40,280 --> 01:28:42,720 to be timely, accurate, and actionable. 1687 01:28:42,720 --> 01:28:45,040 And there have been some allusions to, 1688 01:28:45,040 --> 01:28:48,120 but maybe less direct reference to the compassionate 1689 01:28:48,120 --> 01:28:50,400 or empathetic part of this process. 1690 01:28:50,400 --> 01:28:53,360 But I think it's really key and pivotal 1691 01:28:53,360 --> 01:28:55,800 to the efficacy of detection and diagnosis, 1692 01:28:55,800 --> 01:28:59,120 and so it's an opportunity for research investments 1693 01:28:59,120 --> 01:29:02,000 by an NIA, NINDS, 1694 01:29:02,000 --> 01:29:05,160 and maybe sister institutes across the NIH, 1695 01:29:05,160 --> 01:29:08,160 and certainly private funders as well. 1696 01:29:08,160 --> 01:29:12,040 And I'll flesh it out in the way. 1697 01:29:12,040 --> 01:29:15,000 So you made reference, for instance, 1698 01:29:15,000 --> 01:29:19,200 to diagnose and adiós problem that is endemic in the field, 1699 01:29:19,200 --> 01:29:21,200 and we all know that that plays a role 1700 01:29:21,200 --> 01:29:24,480 in when it happens at the detection stage 1701 01:29:24,480 --> 01:29:27,840 where there is identification of possible cognitive impairment 1702 01:29:27,840 --> 01:29:31,640 and referral to a specialist for a formal diagnosis 1703 01:29:31,640 --> 01:29:34,960 that often families, individual patients, 1704 01:29:34,960 --> 01:29:37,920 do not proceed to that specialist. 1705 01:29:37,920 --> 01:29:42,840 And part of the reason for that is health system infrastructure, 1706 01:29:42,840 --> 01:29:45,520 but part is also the psychological impact 1707 01:29:45,520 --> 01:29:49,680 of a poorly-conveyed detection outcome. 1708 01:29:49,680 --> 01:29:53,400 So if the news is given in a way that is unhelpful, 1709 01:29:53,400 --> 01:29:57,720 unempathetic, lacking compassion, 1710 01:29:57,720 --> 01:30:00,800 it makes it that much harder psychologically for people, 1711 01:30:00,800 --> 01:30:03,120 for patients and their families to take the next step 1712 01:30:03,120 --> 01:30:06,840 and go to the specialist for confirmation or refutation 1713 01:30:06,840 --> 01:30:10,760 of what detection set might turn into a diagnosis 1714 01:30:10,760 --> 01:30:12,320 of cognitive impairment. 1715 01:30:12,320 --> 01:30:16,840 This is fundamentally devastating news for most people 1716 01:30:16,840 --> 01:30:19,240 that know anything about Alzheimer's disease 1717 01:30:19,240 --> 01:30:20,680 or any other form of dementia, 1718 01:30:20,680 --> 01:30:23,200 or they just know the umbrella term "dementia". 1719 01:30:23,200 --> 01:30:28,080 So if this is bad news is not given well, 1720 01:30:28,080 --> 01:30:29,840 it interferes with the likelihood 1721 01:30:29,840 --> 01:30:33,000 that someone will then pursue the specialist confirmation 1722 01:30:33,000 --> 01:30:36,200 or refutation of what detection indicated 1723 01:30:36,200 --> 01:30:38,280 might be at a forthcoming diagnosis. 1724 01:30:38,280 --> 01:30:40,000 So I think it has to be done better. 1725 01:30:40,000 --> 01:30:41,360 It can be done better. 1726 01:30:41,360 --> 01:30:44,040 We know clinicians to do it beautifully. 1727 01:30:44,040 --> 01:30:46,520 We have to figure out how they do it beautifully, 1728 01:30:46,520 --> 01:30:48,200 why they do it beautifully, 1729 01:30:48,200 --> 01:30:53,520 and how to replicate in scale that compassionate element 1730 01:30:53,520 --> 01:30:59,000 of an otherwise professional detection and diagnosis process. 1731 01:30:59,000 --> 01:31:01,080 And I would say the same at the diagnosis 1732 01:31:01,080 --> 01:31:04,120 process by the specialist. 1733 01:31:04,120 --> 01:31:07,400 All the good recommendations about making it actionable, 1734 01:31:07,400 --> 01:31:11,680 referral to community services, getting one's legal, medical, 1735 01:31:11,680 --> 01:31:13,280 and other affairs in order, etc., 1736 01:31:13,280 --> 01:31:17,000 that all goes out the window if patients 1737 01:31:17,000 --> 01:31:20,920 and families emotionally shut down 1738 01:31:20,920 --> 01:31:25,720 because the news was not given in a way that was supportive. 1739 01:31:25,720 --> 01:31:28,920 So we can do it a little research figure out 1740 01:31:28,920 --> 01:31:32,440 how to do it well. And then two last points. 1741 01:31:32,440 --> 01:31:35,280 I apologize for taking so much time. 1742 01:31:35,280 --> 01:31:36,720 We have to be thoughtful 1743 01:31:36,720 --> 01:31:39,720 about the psychological burden on providers, 1744 01:31:39,720 --> 01:31:42,760 on healthcare providers themselves. 1745 01:31:42,760 --> 01:31:46,600 It is traumatizing to give bad news for a living. 1746 01:31:46,600 --> 01:31:48,560 It can be a little less traumatizing 1747 01:31:48,560 --> 01:31:50,640 if you have tools and resources 1748 01:31:50,640 --> 01:31:53,800 to give to patients and their families, 1749 01:31:53,800 --> 01:31:55,400 but there is still the potential, 1750 01:31:55,400 --> 01:32:00,560 and I think the likelihood for some accumulation 1751 01:32:00,560 --> 01:32:01,960 of psychological, 1752 01:32:01,960 --> 01:32:04,360 negative psychological impact on providers. 1753 01:32:04,360 --> 01:32:07,120 And to the point that Heather drew out, 1754 01:32:07,120 --> 01:32:09,800 I thought really beautifully in her presentation, 1755 01:32:09,800 --> 01:32:12,120 all the workforce challenges that we've got 1756 01:32:12,120 --> 01:32:17,760 are that much more vulnerable to becoming worse 1757 01:32:17,760 --> 01:32:20,040 if we don't look after the well-being, 1758 01:32:20,040 --> 01:32:24,000 the psychological well-being of the providers themselves. 1759 01:32:24,000 --> 01:32:27,120 So if we're going to get five-fold increase in the field, 1760 01:32:27,120 --> 01:32:29,360 but have people fall out of the field 1761 01:32:29,360 --> 01:32:34,040 because of the psychological burdens that we don't attend to, 1762 01:32:34,040 --> 01:32:37,120 we'll never get there. And then the last thing, 1763 01:32:37,120 --> 01:32:38,680 and again I won't belabor the point 1764 01:32:38,680 --> 01:32:41,160 because you all have correctly 1765 01:32:41,160 --> 01:32:43,720 and beautifully identified health equity 1766 01:32:43,720 --> 01:32:47,120 as a crosscutting core element of the work, 1767 01:32:47,120 --> 01:32:51,320 but all of the research about how to passionately, 1768 01:32:51,320 --> 01:32:52,840 psychologically, 1769 01:32:52,840 --> 01:32:57,080 appropriately convey and conduct detection and diagnosis, 1770 01:32:57,080 --> 01:33:01,040 that all has to be tailored in a culturally-appropriate way. 1771 01:33:01,040 --> 01:33:04,720 One-size-fits-all is going to be a recipe for failure 1772 01:33:04,720 --> 01:33:08,240 both for physicians and their ancillary staff, 1773 01:33:08,240 --> 01:33:12,800 as well as for patients, human beings, 1774 01:33:12,800 --> 01:33:16,760 and their ancillary care and support teams. 1775 01:33:16,760 --> 01:33:18,200 So I'll end there. 1776 01:33:18,200 --> 01:33:21,800 Thank you again for your indulgence of time. 1777 01:33:21,800 --> 01:33:23,280 -Thank you. 1778 01:33:23,280 --> 01:33:25,080 I took careful note of these really insightful 1779 01:33:25,080 --> 01:33:28,520 and important recommendations about compassionate disclosure, 1780 01:33:28,520 --> 01:33:30,920 culturally-appropriate disclosure, 1781 01:33:30,920 --> 01:33:33,080 and considering the burdens on providers. 1782 01:33:33,080 --> 01:33:34,760 I agree these need to be 1783 01:33:34,760 --> 01:33:36,400 highlighted more in our recommendations, 1784 01:33:36,400 --> 01:33:38,120 so we'll bring us back to our committee 1785 01:33:38,120 --> 01:33:40,960 and review those together. Thank you. 1786 01:33:40,960 --> 01:33:46,000 So moving onto Penny Dax. 1787 01:33:46,000 --> 01:33:47,920 -Thank you. Penny Dacks with the Association 1788 01:33:47,920 --> 01:33:49,920 for Frontotemporal Degeneration. 1789 01:33:49,920 --> 01:33:53,240 I just wanted to offer a couple quick comments. 1790 01:33:53,240 --> 01:33:56,160 I really applaud the incredible work your group has done. 1791 01:33:56,160 --> 01:33:57,840 And in the interest of time, 1792 01:33:57,840 --> 01:34:00,280 I am not suggesting necessarily response to my comments 1793 01:34:00,280 --> 01:34:01,800 but just something to reflect on 1794 01:34:01,800 --> 01:34:05,800 that we've heard so much throughout the whole meeting 1795 01:34:05,800 --> 01:34:08,320 as we should about the need for inclusivity 1796 01:34:08,320 --> 01:34:10,800 in how we design our research. 1797 01:34:10,800 --> 01:34:13,800 And at the same time, we heard about the need 1798 01:34:13,800 --> 01:34:16,400 for more widespread detection of cognitive impairment 1799 01:34:16,400 --> 01:34:18,080 to detect it earlier. 1800 01:34:18,080 --> 01:34:20,400 And there was a rich discussion of some of the benefits 1801 01:34:20,400 --> 01:34:22,120 and risks as it relates, 1802 01:34:22,120 --> 01:34:25,680 say, to the quality of life and psychological well-being. 1803 01:34:25,680 --> 01:34:28,680 I think there's a lot across those two topics 1804 01:34:28,680 --> 01:34:31,880 that I know I have a lot to learn about, 1805 01:34:31,880 --> 01:34:34,280 and I think the field needs to make sure we're very careful 1806 01:34:34,280 --> 01:34:38,200 about with how do people from different socioeconomic, 1807 01:34:38,200 --> 01:34:41,200 geographic, and racial, and ethnic backgrounds differ 1808 01:34:41,200 --> 01:34:43,920 in their perception of screening for dementia. 1809 01:34:43,920 --> 01:34:45,320 Not just in how they'll receive it, 1810 01:34:45,320 --> 01:34:47,520 but what do they actually want. 1811 01:34:47,520 --> 01:34:49,680 How are they going to respond to it? 1812 01:34:49,680 --> 01:34:52,800 And very importantly, how did their risks and benefits differ? 1813 01:34:52,800 --> 01:34:54,920 So for example, if cognitive impairment 1814 01:34:54,920 --> 01:34:57,960 gets detected in the clinic before families even suspected 1815 01:34:57,960 --> 01:34:59,840 that this is on the horizon, 1816 01:34:59,840 --> 01:35:03,800 it maybe blocks some long-term care insurance. 1817 01:35:03,800 --> 01:35:06,040 You know, has the insurance that we've already gotten to show 1818 01:35:06,040 --> 01:35:08,000 that certain groups are at higher risk of dementia, 1819 01:35:08,000 --> 01:35:09,880 has that already translated into higher insurance 1820 01:35:09,880 --> 01:35:12,320 premiums for individuals? 1821 01:35:12,320 --> 01:35:14,880 I think there's just so much we have to understand 1822 01:35:14,880 --> 01:35:18,800 as we focus on developing preventative therapies 1823 01:35:18,800 --> 01:35:20,480 to understand 1824 01:35:20,480 --> 01:35:23,600 how these things are translating into financial ramifications 1825 01:35:23,600 --> 01:35:27,200 because the insurance groups and all of their technologies 1826 01:35:27,200 --> 01:35:30,000 and all of their policies might be taking our research 1827 01:35:30,000 --> 01:35:33,200 and using it in ways that we may not be anticipating. 1828 01:35:33,200 --> 01:35:35,360 I think we need policy research to understand 1829 01:35:35,360 --> 01:35:38,440 how our advances are affecting the most vulnerable 1830 01:35:38,440 --> 01:35:42,520 in our communities at that financial and policy level, 1831 01:35:42,520 --> 01:35:45,000 and how it's affecting employment risk, 1832 01:35:45,000 --> 01:35:48,200 insurance risks. 1833 01:35:48,200 --> 01:35:50,760 And I just wanted to also emphasize 1834 01:35:50,760 --> 01:35:52,960 that some of the pragmatic intervention research 1835 01:35:52,960 --> 01:35:56,600 that Dr. Okonkwo really eloquently framed 1836 01:35:56,600 --> 01:35:58,120 I think it's also really foundational 1837 01:35:58,120 --> 01:35:59,800 and important to communicate 1838 01:35:59,800 --> 01:36:03,160 when we're asking these groups to participate in research 1839 01:36:03,160 --> 01:36:07,040 to help them understand that value is to them 1840 01:36:07,040 --> 01:36:09,880 and their communities is first and foremost in everybody's mind 1841 01:36:09,880 --> 01:36:12,640 as we ask them to participate in research. 1842 01:36:12,640 --> 01:36:15,120 And I thank you again for all of your time. 1843 01:36:17,720 --> 01:36:19,600 -Thank you. Well put, Penny. 1844 01:36:19,600 --> 01:36:24,200 I think these are important points that we can incorporate 1845 01:36:24,200 --> 01:36:27,000 perhaps into our recommendation too. 1846 01:36:27,000 --> 01:36:29,920 If there's no comment from the panel, 1847 01:36:29,920 --> 01:36:31,320 we'll just take note of this 1848 01:36:31,320 --> 01:36:33,400 and bring it back for discussion to our group. 1849 01:36:33,400 --> 01:36:36,000 I agree with these points. Sorry, Penny, one more thing? 1850 01:36:36,000 --> 01:36:38,520 -I'm so sorry. I just also forgot to say that 1851 01:36:38,520 --> 01:36:41,160 for those that are early detection of dementia 1852 01:36:41,160 --> 01:36:43,400 and early onset dementia, 1853 01:36:43,400 --> 01:36:45,280 that's when people are the most reliant 1854 01:36:45,280 --> 01:36:48,000 on their income and their employment. 1855 01:36:48,000 --> 01:36:52,120 And I think that's where we need to pay really careful attention. 1856 01:36:52,120 --> 01:36:55,640 -Thank you. So in the interest of time, 1857 01:36:55,640 --> 01:36:57,440 I think will move on to the next question, 1858 01:36:57,440 --> 01:37:01,600 which I believe was Dezheap? 1859 01:37:01,600 --> 01:37:04,080 Let's see. I don't have the full name here, but. 1860 01:37:04,080 --> 01:37:05,640 -Yeah. Yeah. 1861 01:37:05,640 --> 01:37:06,960 -Okay. Great. 1862 01:37:06,960 --> 01:37:08,800 Please introduce yourself and ask your -- 1863 01:37:08,800 --> 01:37:10,680 or offer your point. 1864 01:37:10,680 --> 01:37:13,120 -Okay. So I'm Dezarell. 1865 01:37:13,120 --> 01:37:17,040 I'm a professor in the University of Minnesota. 1866 01:37:17,040 --> 01:37:18,560 So I have a question. 1867 01:37:18,560 --> 01:37:22,800 So I studied cell biology and the also animal model. 1868 01:37:22,800 --> 01:37:30,240 So all, like, [Indistinct] nuclei, beta, mechanic injury, 1869 01:37:30,240 --> 01:37:33,400 infection, all affect how. 1870 01:37:33,400 --> 01:37:37,960 So POW is a common downstream mechanism. 1871 01:37:37,960 --> 01:37:44,520 And my question is what proportion of dementia patients, 1872 01:37:44,520 --> 01:37:49,440 have a POW pathology? Can anyone answer that? 1873 01:37:49,440 --> 01:37:53,760 Maybe we should -- and I don't want to -- 1874 01:37:53,760 --> 01:37:57,680 maybe we should increase the research effort on POW 1875 01:37:57,680 --> 01:38:02,400 because it started coming downstream pocket 1876 01:38:02,400 --> 01:38:05,840 for so many multiple newly-degenerative disease. 1877 01:38:05,840 --> 01:38:08,040 I will stop here. Thank you. 1878 01:38:08,040 --> 01:38:09,680 -Dazerell, thank you very much. 1879 01:38:09,680 --> 01:38:12,320 This is Dr. Lea Grinberg. I'm a neuropathologist at UCSF, 1880 01:38:12,320 --> 01:38:15,160 and it's a pleasure trying to answer this question 1881 01:38:15,160 --> 01:38:17,200 with the best of my knowledge. 1882 01:38:17,200 --> 01:38:18,960 Thank you very much for your question. 1883 01:38:18,960 --> 01:38:21,920 I think for a neuropathologist and many others in the field, 1884 01:38:21,920 --> 01:38:27,000 this is a quite important question that we face every day. 1885 01:38:27,000 --> 01:38:29,600 Actually one of the recommendations for this group 1886 01:38:29,600 --> 01:38:34,360 is to try to promote even better mapping studies 1887 01:38:34,360 --> 01:38:36,440 especially using human neuropathology 1888 01:38:36,440 --> 01:38:38,280 to understand these questions. 1889 01:38:38,280 --> 01:38:40,480 And this is based on the amazing results 1890 01:38:40,480 --> 01:38:44,160 that we got from a recent clinical pathological cohort 1891 01:38:44,160 --> 01:38:46,440 and how much we learned from this. 1892 01:38:46,440 --> 01:38:48,160 So a simple answer to your question 1893 01:38:48,160 --> 01:38:51,080 is that most of the patients that have dementia 1894 01:38:51,080 --> 01:38:55,720 and come to autopsy, they have multiple pathologies, 1895 01:38:55,720 --> 01:38:59,920 and pathologies that involve POW is one of them. 1896 01:38:59,920 --> 01:39:03,200 In neuropathological studies, we have the ability 1897 01:39:03,200 --> 01:39:06,520 to try to classify these neuropathies. 1898 01:39:06,520 --> 01:39:10,480 And in most cases, we see POW that is related 1899 01:39:10,480 --> 01:39:14,760 to Alzheimer's disease neuropathological changes. 1900 01:39:14,760 --> 01:39:16,400 When it comes from amyloid, 1901 01:39:16,400 --> 01:39:17,920 we call this Alzheimer's disease. 1902 01:39:17,920 --> 01:39:19,800 When it doesn't come with amyloid, 1903 01:39:19,800 --> 01:39:21,200 we might call this Scart. 1904 01:39:21,200 --> 01:39:24,600 Some call early Alzheimer disease stages. 1905 01:39:24,600 --> 01:39:28,400 We have POW that deposits in glial cells and astroglia, 1906 01:39:28,400 --> 01:39:31,600 what we call rTag that it's very common during aging. 1907 01:39:31,600 --> 01:39:35,000 And in populations over 80, we might find it in 1908 01:39:35,000 --> 01:39:39,200 at least 50% of the cases. And it's the same for a change 1909 01:39:39,200 --> 01:39:41,160 that call agraphiac brain disease 1910 01:39:41,160 --> 01:39:43,640 that the field doesn't know exactly what it does, 1911 01:39:43,640 --> 01:39:47,240 if it's a foe or if it's a friend. 1912 01:39:47,240 --> 01:39:50,400 Now to answer the question in another way, 1913 01:39:50,400 --> 01:39:51,760 when we look at patients 1914 01:39:51,760 --> 01:39:54,000 that the primary neuropathological diagnosis 1915 01:39:54,000 --> 01:39:57,120 is not related to POW, for instance, Lewy body disease, 1916 01:39:57,120 --> 01:40:03,440 or to TDP 43 protein properties, it's still just a minority. 1917 01:40:03,440 --> 01:40:06,120 We won't have any kind of POW deposits, 1918 01:40:06,120 --> 01:40:09,760 especially of the AD-type. So thank you for a question. 1919 01:40:09,760 --> 01:40:11,600 It's something that certainly this group thinks 1920 01:40:11,600 --> 01:40:14,880 we have to pursue, especially in diverse population 1921 01:40:14,880 --> 01:40:16,640 because most of our understanding 1922 01:40:16,640 --> 01:40:20,000 comes from Caucasians. Thank you very much. 1923 01:40:22,280 --> 01:40:23,840 -Thank you, Dr. Grinberg. 1924 01:40:23,840 --> 01:40:25,520 We have just a couple more minutes. 1925 01:40:25,520 --> 01:40:27,400 We're cutting into the break for those of you 1926 01:40:27,400 --> 01:40:29,240 who are still with us. 1927 01:40:29,240 --> 01:40:30,960 Let's try to get some brief comments 1928 01:40:30,960 --> 01:40:34,840 if possible from Constantino, and then Helen Metzger, 1929 01:40:34,840 --> 01:40:38,200 and then we'll take a break. So Constantino? 1930 01:40:38,200 --> 01:40:40,920 -Hi. Thank you.

I'll start was just quick definitions. 2030 01:45:40,000 --> 01:45:43,480 A traumatic brain injury is a blow or jolt to the head 2031 01:45:43,480 --> 01:45:48,520 or neck that result in a loss or alteration of consciousness. 2032 01:45:48,520 --> 01:45:51,640 The pyramid on the right illustrates the CDC's estimate 2033 01:45:51,640 --> 01:45:54,400 that almost three million Americans need care 2034 01:45:54,400 --> 01:45:57,840 in the emergency department for TBI each year. 2035 01:45:57,840 --> 01:46:00,200 Next slide. 2036 01:46:00,200 --> 01:46:03,040 TBI can result in a range of symptoms. 2037 01:46:03,040 --> 01:46:05,800 In general, we expect that most people 2038 01:46:05,800 --> 01:46:08,600 with an uncomplicated mild TBI, 2039 01:46:08,600 --> 01:46:10,800 which is sometimes called a concussion, 2040 01:46:10,800 --> 01:46:14,440 to recover completely within days or weeks. 2041 01:46:14,440 --> 01:46:17,080 Next slide. 2042 01:46:17,080 --> 01:46:19,400 However, those with more severe injuries 2043 01:46:19,400 --> 01:46:22,040 may experience more severe consequences, 2044 01:46:22,040 --> 01:46:24,800 including lifelong disability or death. 2045 01:46:24,800 --> 01:46:27,800 The estimates you see here are based on data 2046 01:46:27,800 --> 01:46:29,600 collected through the NIDILRR-funded 2047 01:46:29,600 --> 01:46:32,440 TBI Model Systems National Data. 2048 01:46:32,440 --> 01:46:34,960 And as you can see about one in five have died 2049 01:46:34,960 --> 01:46:37,120 within five years of injury. 2050 01:46:37,120 --> 01:46:40,200 Thirty % experienced deterioration and function 2051 01:46:40,200 --> 01:46:43,920 between one and five years, and the remaining survivors 2052 01:46:43,920 --> 01:46:46,800 either remain functionally-stable or improved. 2053 01:46:46,800 --> 01:46:48,880 Next slide. 2054 01:46:48,880 --> 01:46:52,040 But how does this observed decline relate to dementia? 2055 01:46:52,040 --> 01:46:54,000 For years, we have been taught that 2056 01:46:54,000 --> 01:46:57,800 TBI is one of the strongest environmental risk factors 2057 01:46:57,800 --> 01:47:00,160 for Alzheimer's disease. 2058 01:47:00,160 --> 01:47:02,160 But as this area of study has matured, 2059 01:47:02,160 --> 01:47:05,440 we have learned that the reality is far more complex. 2060 01:47:05,440 --> 01:47:07,360 Results vary across studies 2061 01:47:07,360 --> 01:47:10,440 that differ tremendously in their methodology, 2062 01:47:10,440 --> 01:47:11,880 their sampling strategies 2063 01:47:11,880 --> 01:47:15,840 and their definitions of TBI and dementia. 2064 01:47:15,840 --> 01:47:18,800 In general though, we do see that more severe injury 2065 01:47:18,800 --> 01:47:21,800 tends to be associated with greater dementia risk, 2066 01:47:21,800 --> 01:47:24,080 and TBI is a well-recognized 2067 01:47:24,080 --> 01:47:27,560 and potentially modifiable risk factor for dementia. 2068 01:47:27,560 --> 01:47:29,800 Next slide. 2069 01:47:29,800 --> 01:47:32,440 Although a global pandemic began just months 2070 01:47:32,440 --> 01:47:36,800 after releasing our 2019 research recommendations, 2071 01:47:36,800 --> 01:47:39,160 substantial progress has been made. 2072 01:47:39,160 --> 01:47:41,600 Next slide. 2073 01:47:41,600 --> 01:47:45,240 First, we have -- oh, next slide. 2074 01:47:45,240 --> 01:47:48,000 First we have an updated consensus definition 2075 01:47:48,000 --> 01:47:52,000 for the post-mortem diagnosis CTE neuropathology. 2076 01:47:52,000 --> 01:47:56,200 CTE is believed to be related to repetitive head trauma exposure 2077 01:47:56,200 --> 01:47:59,440 and revised criteria provide a more precise definition 2078 01:47:59,440 --> 01:48:02,040 of the pathognomonic lesion. 2079 01:48:02,040 --> 01:48:05,440 We also now have a preliminary consensus definition 2080 01:48:05,440 --> 01:48:07,160 for research 2081 01:48:07,160 --> 01:48:10,440 diagnosis of traumatic encephalopathy syndrome, 2082 01:48:10,440 --> 01:48:14,800 which is the proposed clinical correlate of CTE neuropathology. 2083 01:48:14,800 --> 01:48:17,080 This represents an important first step 2084 01:48:17,080 --> 01:48:20,360 towards in vivo diagnosis. 2085 01:48:20,360 --> 01:48:23,640 Our colleagues at BU have begun the hard work of validating 2086 01:48:23,640 --> 01:48:26,200 in vivo criteria for TES, 2087 01:48:26,200 --> 01:48:27,640 and these are the types of studies 2088 01:48:27,640 --> 01:48:31,560 that will pave the way for further refinements. 2089 01:48:31,560 --> 01:48:35,200 Major questions remain though about the minimum thresholds 2090 01:48:35,200 --> 01:48:39,280 for CTE diagnosis, the role of the isolated 2091 01:48:39,280 --> 01:48:43,120 traumatic brain injury in CTE and NTES, 2092 01:48:43,120 --> 01:48:45,800 and the relationships between these pathologies 2093 01:48:45,800 --> 01:48:49,000 and clinical symptoms with other ADRDs. 2094 01:48:49,000 --> 01:48:51,040 Next slide. 2095 01:48:51,040 --> 01:48:52,600 -Two minutes remaining. 2096 01:48:52,600 --> 01:48:56,840 -One major initiative that has resulted since 2019 2097 01:48:56,840 --> 01:49:00,720 is that Connect TBI Study led by Doug Smith and Willie Stewart, 2098 01:49:00,720 --> 01:49:04,320 and 13 institutions also represented. 2099 01:49:04,320 --> 01:49:06,200 This project will evaluate brain tissue 2100 01:49:06,200 --> 01:49:08,200 from cases with traumatic brain injury 2101 01:49:08,200 --> 01:49:11,560 and creative brain repository for tissue sharing. 2102 01:49:11,560 --> 01:49:14,240 Next. We also have a large initiative 2103 01:49:14,240 --> 01:49:17,400 led Ann McKee at Boston University 2104 01:49:17,400 --> 01:49:21,320 that will leverage existing brain banks to -- 2105 01:49:21,320 --> 01:49:23,040 that have very well-characterized 2106 01:49:23,040 --> 01:49:25,040 and fully-harmonized clinical and head trauma 2107 01:49:25,040 --> 01:49:28,920 exposure histories to characterized pathologies 2108 01:49:28,920 --> 01:49:31,160 related to repetitive traumatic brain injury 2109 01:49:31,160 --> 01:49:34,440 and head trauma, and their clinical phenotypes. 2110 01:49:34,440 --> 01:49:36,280 Next slide. 2111 01:49:36,280 --> 01:49:39,840 We've also been able to expand the late effects of TBI Project, 2112 01:49:39,840 --> 01:49:42,080 which is a perspective brain donor program 2113 01:49:42,080 --> 01:49:43,960 with autopsy endpoints, 2114 01:49:43,960 --> 01:49:47,160 and this will allow us to expand to our community recruitment 2115 01:49:47,160 --> 01:49:49,520 and longitudinal follow-up. 2116 01:49:49,520 --> 01:49:52,680 Next slide. Okay. 2117 01:49:52,680 --> 01:49:57,720 So our subcommittee's first recommendation reflects the fact 2118 01:49:57,720 --> 01:50:00,960 that this is a relatively new area of investigation. 2119 01:50:00,960 --> 01:50:03,680 And we really feel that we can learn from our colleagues 2120 01:50:03,680 --> 01:50:06,640 who have been studying dementia for decades. 2121 01:50:06,640 --> 01:50:09,040 We identify really important opportunities 2122 01:50:09,040 --> 01:50:13,160 for interdisciplinary crosstalk and expanding collaboration 2123 01:50:13,160 --> 01:50:17,560 across traditionally siloed areas of study. 2124 01:50:17,560 --> 01:50:19,680 Next slide. 2125 01:50:19,680 --> 01:50:23,000 For starters, we hope to convene a working group of stakeholders 2126 01:50:23,000 --> 01:50:26,600 in the TBI and multiple ideology dementia communities 2127 01:50:26,600 --> 01:50:31,000 to evaluate the extent to which current knowledge in ADRD 2128 01:50:31,000 --> 01:50:35,000 can the applied to the study of dementia after TBI, 2129 01:50:35,000 --> 01:50:38,280 and also how our understanding of the acute 2130 01:50:38,280 --> 01:50:40,640 and chronic pathophysiology of TBI 2131 01:50:40,640 --> 01:50:44,640 can contribute to our understanding of ADRDs. 2132 01:50:44,640 --> 01:50:48,000 Again, since TBI is a risk factor with a time zero, 2133 01:50:48,000 --> 01:50:49,320 we believe that further study 2134 01:50:49,320 --> 01:50:52,800 will benefit the entire ADRD community. 2135 01:50:52,800 --> 01:50:55,360 I also say, and this is a figure you've seen before, 2136 01:50:55,360 --> 01:50:57,640 is when we recalculate the population 2137 01:50:57,640 --> 01:51:02,800 attributable factor of dementia risk using population 2138 01:51:02,800 --> 01:51:06,000 representative data on TBI prevalence, 2139 01:51:06,000 --> 01:51:09,480 we see that the number of dementia cases 2140 01:51:09,480 --> 01:51:12,160 that may be at least partially attributable to TBI 2141 01:51:12,160 --> 01:51:14,040 is actually perhaps much greater. 2142 01:51:14,040 --> 01:51:16,200 Next slide. 2143 01:51:16,200 --> 01:51:18,080 Another component of our first recommendation 2144 01:51:18,080 --> 01:51:20,520 is to harmonize existing data 2145 01:51:20,520 --> 01:51:24,800 across longitudinal TBI and ADRD studies. 2146 01:51:24,800 --> 01:51:29,000 Here we illustrate one example of an effort along these lines 2147 01:51:29,000 --> 01:51:32,640 to pull data from five studies of cognitive aging. 2148 01:51:32,640 --> 01:51:38,040 So we have newly collected very detailed characterization 2149 01:51:38,040 --> 01:51:40,200 of lifetime TBI exposure, 2150 01:51:40,200 --> 01:51:44,160 which will allow us to examine late life implications of TBI. 2151 01:51:44,160 --> 01:51:50,200 And we're using IRT-based methods to co-calibrate data 2152 01:51:50,200 --> 01:51:52,680 that were gathered from different measures 2153 01:51:52,680 --> 01:51:56,240 of the same constructs, such as cognition and mood. 2154 01:51:56,240 --> 01:51:58,480 Efforts like this can allow us 2155 01:51:58,480 --> 01:52:01,200 to conduct more granular investigation 2156 01:52:01,200 --> 01:52:07,520 into the intersecting factors that influence risk for ADRD 2157 01:52:07,520 --> 01:52:11,280 well beyond what would be possible in a single study. 2158 01:52:11,280 --> 01:52:15,600 Next slide. Ideally, future efforts 2159 01:52:15,600 --> 01:52:19,920 will maximize measurement harmonization from the start 2160 01:52:19,920 --> 01:52:24,600 by prospectively collecting multimodal common data elements 2161 01:52:24,600 --> 01:52:27,760 to facilitate comparisons and data sharing. 2162 01:52:27,760 --> 01:52:29,680 The ENIGMA Brain Injury Initiative 2163 01:52:29,680 --> 01:52:33,840 is one example of a global working group with these goals. 2164 01:52:33,840 --> 01:52:36,200 Next slide. 2165 01:52:36,200 --> 01:52:39,000 Post-mortem TBI common data elements, 2166 01:52:39,000 --> 01:52:43,200 which is actually another area of progress since 2019, 2167 01:52:43,200 --> 01:52:46,720 provide a road map for prospective collection 2168 01:52:46,720 --> 01:52:48,880 of harmonized data. 2169 01:52:48,880 --> 01:52:52,080 Our hope is that existing brain banks 2170 01:52:52,080 --> 01:52:55,960 will use these common neuropathological methods 2171 01:52:55,960 --> 01:52:58,920 and post-mortem family interview methods 2172 01:52:58,920 --> 01:53:03,800 to characterize post-TBI ADRD and facilitate data 2173 01:53:03,800 --> 01:53:07,000 sharing and cross study comparisons. 2174 01:53:07,000 --> 01:53:09,240 Next slide. 2175 01:53:09,240 --> 01:53:13,120 The Olympic Sensi studies provide another great roadmap 2176 01:53:13,120 --> 01:53:16,040 for neural imaging, harmonization in particular. 2177 01:53:16,040 --> 01:53:19,440 So they aligned with ADME from the start 2178 01:53:19,440 --> 01:53:24,000 by maximizing overlap of both clinical and imaging metrics. 2179 01:53:24,000 --> 01:53:26,960 For example, they used a unique phantom 2180 01:53:26,960 --> 01:53:29,600 that has an isotropic diffusion capabilities 2181 01:53:29,600 --> 01:53:32,720 with hollow fibers the size of axons 2182 01:53:32,720 --> 01:53:35,480 to mimic the diffusion properties 2183 01:53:35,480 --> 01:53:38,200 of diffused axonal injury 2184 01:53:38,200 --> 01:53:40,520 and other tissue properties of relevance 2185 01:53:40,520 --> 01:53:45,000 to both traumatic brain injury and neurodegenerative disease. 2186 01:53:45,000 --> 01:53:46,600 Next slide. 2187 01:53:48,640 --> 01:53:50,640 Our committee believes that neuroinformatics 2188 01:53:50,640 --> 01:53:53,560 will play an important role as well. 2189 01:53:53,560 --> 01:53:58,720 So our first recommendation will require modern cloud-based 2190 01:53:58,720 --> 01:54:01,520 informatics and analytics harmonization platforms 2191 01:54:01,520 --> 01:54:04,400 for QA, post-processing, 2192 01:54:04,400 --> 01:54:07,160 and harmonizing data across sites, 2193 01:54:07,160 --> 01:54:09,200 and scanners, and software. 2194 01:54:09,200 --> 01:54:13,320 Historically, we have had to sometimes sacrifice precision 2195 01:54:13,320 --> 01:54:16,480 for generalizability successfully harmonizing 2196 01:54:16,480 --> 01:54:18,400 only relatively crude metrics 2197 01:54:18,400 --> 01:54:22,320 across major scanner vendors and software platforms. 2198 01:54:22,320 --> 01:54:24,520 But modern informatics platforms 2199 01:54:24,520 --> 01:54:27,080 can automate many aspects of this, 2200 01:54:27,080 --> 01:54:32,200 which again is necessary for multi-site studies. Next. 2201 01:54:32,200 --> 01:54:35,600 Recent examples of an international collaboration 2202 01:54:35,600 --> 01:54:38,800 that required harmonization across continents 2203 01:54:38,800 --> 01:54:42,480 is seen on the track TBI and center TBI studies. 2204 01:54:42,480 --> 01:54:44,960 And again, this may be a great future opportunity. 2205 01:54:44,960 --> 01:54:48,240 Next slide. 2206 01:54:48,240 --> 01:54:50,280 The final component of recommendation one 2207 01:54:50,280 --> 01:54:52,880 is the need to encourage collaboration 2208 01:54:52,880 --> 01:54:56,480 between clinical researchers, biostatisticians, 2209 01:54:56,480 --> 01:54:58,200 epidemiologists, 2210 01:54:58,200 --> 01:55:01,360 and data scientists to incorporate 2211 01:55:01,360 --> 01:55:04,360 multi-dimensional, multimodal data, 2212 01:55:04,360 --> 01:55:08,360 and employ more sophisticated causal inference methodologies, 2213 01:55:08,360 --> 01:55:10,800 and work with implementation scientists 2214 01:55:10,800 --> 01:55:15,560 to maximize the clinical translatability of this work. 2215 01:55:15,560 --> 01:55:18,320 This is inherently interdisciplinary, 2216 01:55:18,320 --> 01:55:22,600 and collaboration is required to move the science forward. 2217 01:55:22,600 --> 01:55:24,880 Next slide. 2218 01:55:24,880 --> 01:55:27,840 Our second recommendation pertains to clinical phenotyping 2219 01:55:27,840 --> 01:55:30,200 across exposure histories 2220 01:55:30,200 --> 01:55:33,880 to pave the way for in vivo diagnostics. 2221 01:55:33,880 --> 01:55:36,320 Next slide. 2222 01:55:36,320 --> 01:55:39,960 First, we need to establish and validate 2223 01:55:39,960 --> 01:55:44,040 a quantitative index of lifetime head trauma exposure. 2224 01:55:44,040 --> 01:55:46,440 One thing we have learned is that administrative data 2225 01:55:46,440 --> 01:55:50,400 only identifies those who have sought and received care. 2226 01:55:50,400 --> 01:55:52,520 So self-report is considered 2227 01:55:52,520 --> 01:55:56,840 the gold standard for lifetime TBI exposure. 2228 01:55:56,840 --> 01:55:59,480 We consistently find that structured questionnaires 2229 01:55:59,480 --> 01:56:03,720 that use contextual cueing for lifetime injury reporting, 2230 01:56:03,720 --> 01:56:06,240 such as the Ohio State University 2231 01:56:06,240 --> 01:56:08,200 TBI identification method, 2232 01:56:08,200 --> 01:56:09,920 or the brain injury screening questionnaire, 2233 01:56:09,920 --> 01:56:11,240 are really required 2234 01:56:11,240 --> 01:56:14,320 for comprehensive exposure ascertainment. 2235 01:56:14,320 --> 01:56:16,880 So this notion that all important TBIs 2236 01:56:16,880 --> 01:56:19,640 are in the medical record is simply untrue. 2237 01:56:19,640 --> 01:56:21,160 Our colleagues have actually found 2238 01:56:21,160 --> 01:56:23,000 that those who never sought care 2239 01:56:23,000 --> 01:56:25,800 have worse long-term outcomes after injury. 2240 01:56:25,800 --> 01:56:29,680 So this not seeking care may actually be an important proxy 2241 01:56:29,680 --> 01:56:33,720 for other factors that matter a lot in long-term outcomes. 2242 01:56:33,720 --> 01:56:35,080 The last thing I'll say about this 2243 01:56:35,080 --> 01:56:36,920 is in the upper righthand corner there, 2244 01:56:36,920 --> 01:56:41,280 you see that single TBI rarely exists in isolation 2245 01:56:41,280 --> 01:56:45,680 so you see their data from a moderate severe TBI study 2246 01:56:45,680 --> 01:56:47,960 that shows that about half of the sample 2247 01:56:47,960 --> 01:56:51,800 with a single TBI also have repetitive head injury 2248 01:56:51,800 --> 01:56:54,680 in the context of sports, or military service, 2249 01:56:54,680 --> 01:56:56,600 or intimate partner violence. 2250 01:56:56,600 --> 01:57:00,720 Many also had multiple isolated TBIs. 2251 01:57:00,720 --> 01:57:04,400 So the question of how to quantify lifetime exposure 2252 01:57:04,400 --> 01:57:07,280 in a way that reflects clinical reality 2253 01:57:07,280 --> 01:57:09,840 will be foundational to this area of study. 2254 01:57:09,840 --> 01:57:11,800 Next slide. 2255 01:57:11,800 --> 01:57:14,600 Similarly crucial is the need to establish 2256 01:57:14,600 --> 01:57:17,400 and validate a provisional definition, 2257 01:57:17,400 --> 01:57:21,080 a clinical definition of post-TBI dementias 2258 01:57:21,080 --> 01:57:25,400 that distinguishes chronic effects of TBI 2259 01:57:25,400 --> 01:57:29,400 from a progressive neurodegenerative disease. 2260 01:57:29,400 --> 01:57:33,240 So because the term "dementia" is broad 2261 01:57:33,240 --> 01:57:35,680 and has multiple clinical definitions, 2262 01:57:35,680 --> 01:57:38,160 it has sometimes been used to characterize 2263 01:57:38,160 --> 01:57:40,400 the acute effects of TBI 2264 01:57:40,400 --> 01:57:44,280 or the stable chronic effects of TBI. 2265 01:57:44,280 --> 01:57:47,320 And so a definition such as what you see here, 2266 01:57:47,320 --> 01:57:53,200 wherein post-TBI ADRD is defined as post-recovery decline 2267 01:57:53,200 --> 01:57:58,200 really requires further study and validation. Next. 2268 01:57:58,200 --> 01:58:00,720 Out committee felt that longitudinal studies 2269 01:58:00,720 --> 01:58:03,880 are especially essential to recommendation two, 2270 01:58:03,880 --> 01:58:06,480 which is to characterize the clinical phenotype 2271 01:58:06,480 --> 01:58:10,240 and the phenotypic heterogeneity and clinical course, 2272 01:58:10,240 --> 01:58:12,680 the protective factors 2273 01:58:12,680 --> 01:58:17,560 and the effect modifiers of post-TBI ADRDs. 2274 01:58:17,560 --> 01:58:19,200 It may be especially informative 2275 01:58:19,200 --> 01:58:22,400 to study people prospectively from the time of injury 2276 01:58:22,400 --> 01:58:24,800 to understand the primary pathology, 2277 01:58:24,800 --> 01:58:27,040 the secondary injury processes, 2278 01:58:27,040 --> 01:58:30,880 and the long-term outcomes as they evolve over time. 2279 01:58:30,880 --> 01:58:32,320 The TBI model systems, 2280 01:58:32,320 --> 01:58:35,160 for example the track TBI Study and Evolve Study 2281 01:58:35,160 --> 01:58:37,640 are three examples of these prospective studies 2282 01:58:37,640 --> 01:58:39,880 with complementary strengths. 2283 01:58:39,880 --> 01:58:42,240 So the Evolve Study, for example, 2284 01:58:42,240 --> 01:58:45,080 led by Christine McDonald follows active duty 2285 01:58:45,080 --> 01:58:47,680 military service members from the battlefield 2286 01:58:47,680 --> 01:58:50,440 and is now approaching a 10-year follow-up. 2287 01:58:50,440 --> 01:58:53,640 And this has uncovered a pattern suggesting evolution 2288 01:58:53,640 --> 01:58:58,080 as opposed to a resolution of symptoms over time. 2289 01:58:58,080 --> 01:59:01,400 The TBI model system is the largest prospective 2290 01:59:01,400 --> 01:59:04,640 TBI outcome study in the world. 2291 01:59:04,640 --> 01:59:06,200 But with telephone data collection, 2292 01:59:06,200 --> 01:59:09,400 it doesn't currently include biological markers. 2293 01:59:09,400 --> 01:59:11,400 So we have a tremendous opportunity 2294 01:59:11,400 --> 01:59:14,360 to learn from these types of studies. 2295 01:59:14,360 --> 01:59:19,160 Next slide. We currently do not know 2296 01:59:19,160 --> 01:59:24,560 how post-TBI ADRD relates to other ADRDs. 2297 01:59:24,560 --> 01:59:27,160 The studies illustrated here suggests that older adults 2298 01:59:27,160 --> 01:59:30,040 with TBI have more motor impairment 2299 01:59:30,040 --> 01:59:33,120 and more pronounced neurobehavioral symptoms 2300 01:59:33,120 --> 01:59:34,360 relative to those 2301 01:59:34,360 --> 01:59:36,800 with Alzheimer's disease in particular. 2302 01:59:36,800 --> 01:59:40,400 And on the right, you see that compared to older adults 2303 01:59:40,400 --> 01:59:43,920 without TBI, their cognitive profiles 2304 01:59:43,920 --> 01:59:46,000 suggest more difficulty with executive 2305 01:59:46,000 --> 01:59:48,120 functioning and processing speed, 2306 01:59:48,120 --> 01:59:51,080 which are hallmark characteristics of TBI, 2307 01:59:51,080 --> 01:59:54,800 but not characteristic of AD-type dementia. 2308 01:59:54,800 --> 01:59:57,800 Next slide. 2309 01:59:57,800 --> 02:00:01,640 Phenotyping a heterogenous multi-ideology disease 2310 02:00:01,640 --> 02:00:04,000 process is no small task, 2311 02:00:04,000 --> 02:00:07,600 and efforts to-date were recently summarized 2312 02:00:07,600 --> 02:00:10,680 in this brain trauma blueprint paper 2313 02:00:10,680 --> 02:00:13,640 that was just published last year. 2314 02:00:13,640 --> 02:00:15,160 These studies do suggest 2315 02:00:15,160 --> 02:00:19,240 that clinically-distinguishable subtypes exist. 2316 02:00:19,240 --> 02:00:22,680 And on the right, we see evidence of a TBI phenotype 2317 02:00:22,680 --> 02:00:28,160 that overlaps with clinical correlates of AD and FTD 2318 02:00:28,160 --> 02:00:30,400 in a sample of post-9/11 veterans 2319 02:00:30,400 --> 02:00:34,960 with early onset dementia. Next slide. 2320 02:00:34,960 --> 02:00:38,280 Central to recommendation two is the need to develop 2321 02:00:38,280 --> 02:00:42,520 and validate post-TBI ADRD biomarkers 2322 02:00:42,520 --> 02:00:47,560 to non-invasively identify progressive pathologies 2323 02:00:47,560 --> 02:00:51,480 and to monitor clinical disease progression over time. 2324 02:00:51,480 --> 02:00:53,840 The radiology biomarkers at the top 2325 02:00:53,840 --> 02:00:56,640 are used for more acute TBI studies 2326 02:00:56,640 --> 02:01:00,400 that can inform studies of the evolution of TBI 2327 02:01:00,400 --> 02:01:04,800 in the transition to recovery or to decline. 2328 02:01:04,800 --> 02:01:08,960 Like other dementias, TBI is not a single disease process 2329 02:01:08,960 --> 02:01:11,440 with the unified path of physiological mechanisms. 2330 02:01:11,440 --> 02:01:15,480 So characterizing the acute and chronic changes 2331 02:01:15,480 --> 02:01:19,160 ideally in longitudinal studies will be highly informative. 2332 02:01:21,400 --> 02:01:25,160 Although substantial progress has been made in acute 2333 02:01:25,160 --> 02:01:29,480 diagnostic and prognostic markers for TBI, 2334 02:01:29,480 --> 02:01:32,200 there has been relatively little investigation 2335 02:01:32,200 --> 02:01:37,000 into biomarkers of posttraumatic neurodegeneration. 2336 02:01:37,000 --> 02:01:39,880 The top candidates though are those 2337 02:01:39,880 --> 02:01:44,400 that can detect traumatic and neuroinflammatory injury, 2338 02:01:44,400 --> 02:01:46,600 and that can also detect the onset 2339 02:01:46,600 --> 02:01:50,640 and progression of neurodegenerative diseases. 2340 02:01:50,640 --> 02:01:54,000 As you can see in the figure on the right, 2341 02:01:54,000 --> 02:01:56,160 our colleague studying Alzheimer's disease 2342 02:01:56,160 --> 02:01:58,360 has found excellent correspondence 2343 02:01:58,360 --> 02:02:02,200 between blood CSF and PET markers. 2344 02:02:02,200 --> 02:02:05,360 And this appears to provide information 2345 02:02:05,360 --> 02:02:07,920 on disease progression of pathologies 2346 02:02:07,920 --> 02:02:13,440 that are also known to be implicated in post-TBI ADRD. 2347 02:02:13,440 --> 02:02:17,360 So these candidate markers really require further study 2348 02:02:17,360 --> 02:02:21,800 in the chronic stages following TBI. 2349 02:02:21,800 --> 02:02:25,240 Finally, the need to recruit diverse samples 2350 02:02:25,240 --> 02:02:27,400 warrants particular mention here. 2351 02:02:27,400 --> 02:02:31,880 This includes men and women with repetitive, 2352 02:02:31,880 --> 02:02:37,800 or isolated, or very diverse injury exposure histories. 2353 02:02:37,800 --> 02:02:40,680 It includes underrepresented minorities. 2354 02:02:40,680 --> 02:02:45,400 It includes, again, a range of head trauma exposures, 2355 02:02:45,400 --> 02:02:47,600 mechanisms, and chronicity. 2356 02:02:47,600 --> 02:02:51,040 And it includes -- it requires clinic 2357 02:02:51,040 --> 02:02:54,120 and community-based recruitment. 2358 02:02:54,120 --> 02:02:57,600 Our colleagues who have been studying dementia for decades 2359 02:02:57,600 --> 02:03:00,640 have demonstrated that those who are recruited 2360 02:03:00,640 --> 02:03:03,800 in the community differ in important ways from those 2361 02:03:03,800 --> 02:03:07,080 who are recruited from clinic-based settings. 2362 02:03:07,080 --> 02:03:10,800 And we expect those differences to, if anything, 2363 02:03:10,800 --> 02:03:14,280 to be more pronounced in the study of post-TBI 2364 02:03:14,280 --> 02:03:20,280 ADRD given the high rates of TBI in homeless shelters, 2365 02:03:20,280 --> 02:03:23,880 substance use disorder treatment settings, prisons, 2366 02:03:23,880 --> 02:03:27,000 and among multiply marginalized populations. 2367 02:03:27,000 --> 02:03:31,080 So we need to ensure that studies of post-TBI 2368 02:03:31,080 --> 02:03:35,400 AD and ADRD include representative samples 2369 02:03:35,400 --> 02:03:39,840 of individuals living with TBI. With that, next slide, 2370 02:03:39,840 --> 02:03:43,280 I will pass the microphone to Dr. Dirk Keene 2371 02:03:43,280 --> 02:03:45,200 from the University of Washington 2372 02:03:45,200 --> 02:03:48,000 who will discuss recommendation three. 2373 02:03:50,160 --> 02:03:55,720 -Thanks, Kristin. Next slide. Great. Next slide. 2374 02:03:55,720 --> 02:03:57,120 So these are the -- 2375 02:03:57,120 --> 02:04:00,160 so recommendation three is really a bridge 2376 02:04:00,160 --> 02:04:02,000 from the first two recommendations 2377 02:04:02,000 --> 02:04:03,720 to the fourth recommendation. 2378 02:04:03,720 --> 02:04:06,880 This is the recommendation listed out 2379 02:04:06,880 --> 02:04:09,800 into the sub recommendations. But if you go to the next slide, 2380 02:04:09,800 --> 02:04:16,320 I've tried to summarize to capture the, you know, 2381 02:04:16,320 --> 02:04:18,400 the recommendations by its essence. 2382 02:04:18,400 --> 02:04:21,440 And really what recommendation three is about 2383 02:04:21,440 --> 02:04:24,400 is supporting and building research infrastructure 2384 02:04:24,400 --> 02:04:29,200 to make sure that we take advantage of the, 2385 02:04:29,200 --> 02:04:32,680 of what's come before us especially with AD 2386 02:04:32,680 --> 02:04:38,320 and other ADRD research to understand 2387 02:04:38,320 --> 02:04:45,880 and bridge what we know about AD and ADRD for TBI-related ADRD. 2388 02:04:45,880 --> 02:04:48,400 And so we need to study representative cohort. 2389 02:04:48,400 --> 02:04:50,840 That can't be emphasized enough. 2390 02:04:50,840 --> 02:04:55,880 At every step, we need to be studying 2391 02:04:55,880 --> 02:05:02,320 the breadth of TBI exposure from ethnic and socioeconomic, 2392 02:05:02,320 --> 02:05:03,840 and other backgrounds. 2393 02:05:03,840 --> 02:05:07,440 We need to studying the representative samples. 2394 02:05:07,440 --> 02:05:10,960 We need to build and enhance our biorepositories, 2395 02:05:10,960 --> 02:05:13,000 that's from a brain biorepositories, 2396 02:05:13,000 --> 02:05:15,200 biofluid biorepositories, 2397 02:05:15,200 --> 02:05:16,960 and then develop standardized approaches. 2398 02:05:16,960 --> 02:05:19,720 So in the next few slides, I'll go over each of these 2399 02:05:19,720 --> 02:05:23,240 in a little bit more depth. Next. 2400 02:05:23,240 --> 02:05:29,240 So the Alzheimer's Disease Research Centers have -- 2401 02:05:29,240 --> 02:05:34,160 it's a really robust multi-center network 2402 02:05:34,160 --> 02:05:36,800 that's been -- that was established by NIA 2403 02:05:36,800 --> 02:05:38,280 over 30 years ago. 2404 02:05:38,280 --> 02:05:40,280 On the right, you can see that states 2405 02:05:40,280 --> 02:05:41,840 that have one or more centers. 2406 02:05:41,840 --> 02:05:44,480 The light blue ones are the exploratory centers. 2407 02:05:44,480 --> 02:05:46,000 This program continues to build. 2408 02:05:46,000 --> 02:05:50,120 And each center has really robust infrastructure 2409 02:05:50,120 --> 02:05:52,760 developed along the lines of cores 2410 02:05:52,760 --> 02:05:56,640 that have led the way in helping us understand 2411 02:05:56,640 --> 02:05:59,240 how to develop prospective studies 2412 02:05:59,240 --> 02:06:04,160 and these multimodal approaches to study disease 2413 02:06:04,160 --> 02:06:06,400 from even pre-symptomatic levels 2414 02:06:06,400 --> 02:06:09,200 all the way through to brain donation 2415 02:06:09,200 --> 02:06:10,680 and neuropathological studies. 2416 02:06:10,680 --> 02:06:16,080 And so I think TBI ADRD can really learn 2417 02:06:16,080 --> 02:06:18,600 from what's been done in Alzheimer's disease 2418 02:06:18,600 --> 02:06:21,800 and Parkinson's disease, these established networks. 2419 02:06:21,800 --> 02:06:23,880 And I think the Alzheimer Center Network 2420 02:06:23,880 --> 02:06:26,680 is a prime example of how AD can leverage 2421 02:06:26,680 --> 02:06:29,080 that infrastructure and that expertise. 2422 02:06:29,080 --> 02:06:31,160 And then also there's other resources 2423 02:06:31,160 --> 02:06:34,160 that have been built up around other focuses, 2424 02:06:34,160 --> 02:06:35,520 other areas of study. 2425 02:06:35,520 --> 02:06:37,840 The National Alzheimer's Coordinating Center 2426 02:06:37,840 --> 02:06:40,640 is a centralized data repository for the Alzheimer's Centers 2427 02:06:40,640 --> 02:06:45,200 and Alzheimer's Disease Research Participant Data. 2428 02:06:45,200 --> 02:06:48,640 The National Centralized Repository for AD, 2429 02:06:48,640 --> 02:06:50,600 and Related Dementias NCRAD 2430 02:06:50,600 --> 02:06:54,800 is really leading the way along with other centers 2431 02:06:54,800 --> 02:07:01,400 on biospecimen storage sharing and characterization. 2432 02:07:01,400 --> 02:07:03,600 And then there's a multitude of other 2433 02:07:03,600 --> 02:07:05,600 really well-established studies in ADRD 2434 02:07:05,600 --> 02:07:10,480 that I think TBI research can leverage and build upon 2435 02:07:10,480 --> 02:07:12,200 so that we're not reinventing the wheel, 2436 02:07:12,200 --> 02:07:15,800 so that we're taking advantage of the incredible investment 2437 02:07:15,800 --> 02:07:21,200 that's been made and it's being made for TBI-related ADRD. 2438 02:07:21,200 --> 02:07:27,440 Next slide. It's really critical to study representative cohorts, 2439 02:07:27,440 --> 02:07:29,640 and to study those cohorts prospectively. 2440 02:07:29,640 --> 02:07:32,400 And so I've listed some community-based cohorts there. 2441 02:07:32,400 --> 02:07:33,720 There's many others. 2442 02:07:33,720 --> 02:07:36,960 But the idea is that you need to start, 2443 02:07:36,960 --> 02:07:39,880 you need to start at the very beginning with cohorts 2444 02:07:39,880 --> 02:07:44,000 that you can characterize clinically, with biomarkers, 2445 02:07:44,000 --> 02:07:46,400 all the way through as the -- 2446 02:07:46,400 --> 02:07:49,720 as TBI-related ADRD and other diseases advance. 2447 02:07:49,720 --> 02:07:53,040 And so these community-based cohorts are really critical 2448 02:07:53,040 --> 02:07:56,520 in representing the diversity of traumatic brain injury exposure, 2449 02:07:56,520 --> 02:07:59,840 the diversity of the population that we're studying 2450 02:07:59,840 --> 02:08:03,600 so that we have inclusion and can understand differences 2451 02:08:03,600 --> 02:08:06,600 and similarities across the population. 2452 02:08:06,600 --> 02:08:08,400 And then what I think is really important 2453 02:08:08,400 --> 02:08:12,200 is to take TBI-related expertise 2454 02:08:12,200 --> 02:08:16,960 and build that into existing and prospective ADRD studies. 2455 02:08:16,960 --> 02:08:19,440 And the same goes for TBI studies 2456 02:08:19,440 --> 02:08:21,280 to really leverage what we know 2457 02:08:21,280 --> 02:08:23,600 and what we've learned through ADRD, 2458 02:08:23,600 --> 02:08:26,000 through our Alzheimer's center and other centers 2459 02:08:26,000 --> 02:08:28,160 to build that into our TBI-related studies 2460 02:08:28,160 --> 02:08:30,320 so that we're talking the same language 2461 02:08:30,320 --> 02:08:32,880 across these different cohorts. Next. 2462 02:08:35,680 --> 02:08:37,320 Kristen mentioned Delayed Effects 2463 02:08:37,320 --> 02:08:40,600 of Traumatic Brain Injury study. 2464 02:08:40,600 --> 02:08:43,920 It's a prime example, I think, of a multimodal approach 2465 02:08:43,920 --> 02:08:46,800 from the time a person enrolls all the way through 2466 02:08:46,800 --> 02:08:51,720 to the time a person dies, if that's the case. 2467 02:08:51,720 --> 02:08:53,760 And collecting as much data along the way 2468 02:08:53,760 --> 02:08:56,560 so that we can relate the different biofluid, 2469 02:08:56,560 --> 02:09:00,200 and cognitive, and other biomarkers to exposure history. 2470 02:09:00,200 --> 02:09:03,800 And also moving forward to neuroimaging 2471 02:09:03,800 --> 02:09:08,120 and also neuropathology markers so that we can link the data 2472 02:09:08,120 --> 02:09:12,800 from one aspect of a study participant all the way back. 2473 02:09:12,800 --> 02:09:16,440 So that we can understand during life what underlies 2474 02:09:16,440 --> 02:09:21,760 the kinds of cognitive deficits or behavioral abnormalities 2475 02:09:21,760 --> 02:09:24,080 that are happening in people that have suffered a TBI. 2476 02:09:24,080 --> 02:09:29,080 And how does that relate to neurodegenerative disease. Next. 2477 02:09:29,080 --> 02:09:32,360 We need to build and enhance brain bio repositories. 2478 02:09:32,360 --> 02:09:34,760 Again, this is the Connect TBI group, 2479 02:09:34,760 --> 02:09:38,080 which is, I think, one very good example, 2480 02:09:38,080 --> 02:09:39,640 along with the BU group, 2481 02:09:39,640 --> 02:09:43,040 of how to leverage existing brain bio repositories 2482 02:09:43,040 --> 02:09:45,680 with a focus on TBI-related neurodegeneration. 2483 02:09:45,680 --> 02:09:47,600 Bringing resources together 2484 02:09:47,600 --> 02:09:50,800 that previously hadn't been brought together 2485 02:09:50,800 --> 02:09:53,800 to try to understand what the relationship 2486 02:09:53,800 --> 02:09:56,720 between TBI exposure and neurodegeneration is. 2487 02:09:56,720 --> 02:09:59,160 There's a number of different other -- 2488 02:09:59,160 --> 02:10:00,600 there's a lot of infrastructure out there 2489 02:10:00,600 --> 02:10:03,160 that we can use to build this together. 2490 02:10:03,160 --> 02:10:06,240 And ultimately use that experience to -- 2491 02:10:06,240 --> 02:10:10,000 into prospective cohort studies where we can tailor 2492 02:10:10,000 --> 02:10:13,040 our characterization of folks all the way through. 2493 02:10:13,040 --> 02:10:20,200 Using the TBI and ADRD-related assessments 2494 02:10:20,200 --> 02:10:22,000 from the time a person enters a study, 2495 02:10:22,000 --> 02:10:24,040 all the way through their different neuroimaging 2496 02:10:24,040 --> 02:10:27,760 and other biomarker studies, through the end of the study. 2497 02:10:27,760 --> 02:10:30,400 Next. 2498 02:10:30,400 --> 02:10:33,080 And so we need to enhance brain bio repositories. 2499 02:10:33,080 --> 02:10:35,720 I use the Brain Initiative here as an example. 2500 02:10:35,720 --> 02:10:38,040 The Brain Initiative is really leading the way. 2501 02:10:38,040 --> 02:10:41,960 It's a major effort from NIH to understand the structure, 2502 02:10:41,960 --> 02:10:45,840 and connectivity, and function of the normal brain. 2503 02:10:45,840 --> 02:10:51,600 They have pioneered new methodologies 2504 02:10:51,600 --> 02:10:54,280 to study human brain tissue 2505 02:10:54,280 --> 02:10:57,920 and those efforts I think we need to work from 2506 02:10:57,920 --> 02:11:00,720 and learn from those efforts when we study ADRD, 2507 02:11:00,720 --> 02:11:03,520 and specifically TBI-related ADRD. 2508 02:11:03,520 --> 02:11:08,000 So that we're maximizing the investment of the NIH 2509 02:11:08,000 --> 02:11:10,560 and other stakeholders in this research. 2510 02:11:10,560 --> 02:11:13,600 And doing everything we can for every person that donates 2511 02:11:13,600 --> 02:11:16,560 their brain to learn as much as we can from their brain. 2512 02:11:16,560 --> 02:11:18,600 And I think this is one example. 2513 02:11:18,600 --> 02:11:19,920 Many of the different brain banks 2514 02:11:19,920 --> 02:11:22,200 are pioneering new methodologies. 2515 02:11:22,200 --> 02:11:25,000 And to the extent that we can learn as much as possible 2516 02:11:25,000 --> 02:11:28,400 from each one of these samples by studying cohort people 2517 02:11:28,400 --> 02:11:31,160 who have been studied all the way during life 2518 02:11:31,160 --> 02:11:32,680 with well-known exposures. 2519 02:11:32,680 --> 02:11:35,400 And then maximizing the technological approaches 2520 02:11:35,400 --> 02:11:38,800 that we have to understanding the different pathways 2521 02:11:38,800 --> 02:11:41,960 to injury and dementia is really important. 2522 02:11:41,960 --> 02:11:46,320 Next slide. And then to establish 2523 02:11:46,320 --> 02:11:48,240 and implement standards for neuropathology. 2524 02:11:48,240 --> 02:11:50,600 Kristen mentioned the CDBs. 2525 02:11:50,600 --> 02:11:53,280 It's really exciting the way this has developed. 2526 02:11:53,280 --> 02:11:58,680 So on the left, in 2012, the National Institute on Aging 2527 02:11:58,680 --> 02:12:01,400 and its Alzheimer's Association guidelines 2528 02:12:01,400 --> 02:12:07,000 for the pathological assessment of AD were published. 2529 02:12:07,000 --> 02:12:08,760 And those really sent the standard 2530 02:12:08,760 --> 02:12:14,240 for how neuropathologists talk to each other about what the -- 2531 02:12:14,240 --> 02:12:18,320 what each brain that they're studying shows. 2532 02:12:18,320 --> 02:12:21,880 The NINDS and NIBIB consensus meetings, 2533 02:12:21,880 --> 02:12:24,720 both the first and second for CTE, 2534 02:12:24,720 --> 02:12:27,040 really built on this in the fact 2535 02:12:27,040 --> 02:12:29,880 that we took those recommendations 2536 02:12:29,880 --> 02:12:32,800 for AD and ADRD neuropath. 2537 02:12:32,800 --> 02:12:37,360 And built on those for the CTE consensus recommendation 2538 02:12:37,360 --> 02:12:42,480 so that we can refer back to brain biorepositories 2539 02:12:42,480 --> 02:12:44,080 even 20, 30 years ago 2540 02:12:44,080 --> 02:12:48,040 with similar sampling processes and assessments. 2541 02:12:48,040 --> 02:12:51,880 To sort of leverage that so that we're understanding TBI 2542 02:12:51,880 --> 02:12:54,520 in the context of neurodegenerative disease. 2543 02:12:54,520 --> 02:12:58,680 And then, finally, thanks to a great group of people, 2544 02:12:58,680 --> 02:13:01,400 the accommodated elements for neuropathology 2545 02:13:01,400 --> 02:13:05,040 that Kristen mentions are essentially done 2546 02:13:05,040 --> 02:13:07,920 and ready for people to start using. 2547 02:13:07,920 --> 02:13:10,360 So we really need, as a community, 2548 02:13:10,360 --> 02:13:14,800 to be hopefully implementing and using these recommendations 2549 02:13:14,800 --> 02:13:16,680 so that, again, we can talk to each other. 2550 02:13:16,680 --> 02:13:18,560 So that the Alzheimer's Disease researcher 2551 02:13:18,560 --> 02:13:20,200 can talk to the TBI researcher 2552 02:13:20,200 --> 02:13:22,320 and we're all using the same language. 2553 02:13:22,320 --> 02:13:26,600 Importantly, in the CDEs, I just want to highlight, 2554 02:13:26,600 --> 02:13:30,000 we intentionally built in the possibility, too, 2555 02:13:30,000 --> 02:13:33,440 for flexibility, so that there's a common baseline. 2556 02:13:33,440 --> 02:13:35,760 But it opens up the -- 2557 02:13:35,760 --> 02:13:40,680 it encourages different biorepositories to study areas 2558 02:13:40,680 --> 02:13:42,120 that they have expertise in, 2559 02:13:42,120 --> 02:13:43,960 areas that may contribute down the road 2560 02:13:43,960 --> 02:13:45,680 to new approaches to this. 2561 02:13:45,680 --> 02:13:49,360 Which I think is really exciting for these CDEs. 2562 02:13:49,360 --> 02:13:51,360 Next slide. 2563 02:13:51,360 --> 02:13:52,560 -Two minutes remaining. 2564 02:13:52,560 --> 02:13:58,120 -Got you. Whoops. 2565 02:14:00,400 --> 02:14:04,560 So the last thing is to leverage and build infrastructure 2566 02:14:04,560 --> 02:14:06,200 to promote tissue and data sharing. 2567 02:14:06,200 --> 02:14:08,600 So this slide is just highlighting what we can do 2568 02:14:08,600 --> 02:14:11,400 once a person has donated their brain. 2569 02:14:11,400 --> 02:14:14,200 We can perform ex vivo neuroimaging, 2570 02:14:14,200 --> 02:14:16,080 extensive sampling. 2571 02:14:16,080 --> 02:14:17,800 We have the ability in many groups 2572 02:14:17,800 --> 02:14:21,200 are imaging and scanning microscope slides 2573 02:14:21,200 --> 02:14:23,600 and there are multiple different repositories 2574 02:14:23,600 --> 02:14:25,680 available to share this information. 2575 02:14:25,680 --> 02:14:28,160 We need to really promote the ability for each of us 2576 02:14:28,160 --> 02:14:29,760 to see what each other is doing 2577 02:14:29,760 --> 02:14:31,600 so that we can learn from each other 2578 02:14:31,600 --> 02:14:33,600 and maximize the investment of the donors 2579 02:14:33,600 --> 02:14:37,600 and the stakeholders. Next slide. 2580 02:14:37,600 --> 02:14:41,920 So this is just highlighting the really critical relevance 2581 02:14:41,920 --> 02:14:45,960 of human brain donation and human research 2582 02:14:45,960 --> 02:14:49,560 in helping us to eventually establish mechanism, 2583 02:14:49,560 --> 02:14:51,160 and that's a mouse brain on the bottom. 2584 02:14:51,160 --> 02:14:54,000 And so what we can learn from human brain 2585 02:14:54,000 --> 02:14:58,760 is what's relevant to the disease or the impairment 2586 02:14:58,760 --> 02:15:00,440 and we can generate hypotheses. 2587 02:15:00,440 --> 02:15:02,640 But the only way we can go test those hypotheses, 2588 02:15:02,640 --> 02:15:05,880 and establish mechanism, and ultimately develop treatments 2589 02:15:05,880 --> 02:15:10,320 to test in back in people is with these experimental systems. 2590 02:15:10,320 --> 02:15:11,840 Next slide. 2591 02:15:11,840 --> 02:15:14,680 And so human neuropathology and these -- 2592 02:15:14,680 --> 02:15:18,960 and from really well-studied and representative diverse 2593 02:15:18,960 --> 02:15:21,080 cohorts is just essential. 2594 02:15:21,080 --> 02:15:24,000 And neuropathology can provide a bridge 2595 02:15:24,000 --> 02:15:26,680 from those outstanding representative cohort -- 2596 02:15:26,680 --> 02:15:28,600 prospective cohort studies. 2597 02:15:28,600 --> 02:15:31,000 Ultimately to where we can understand mechanisms 2598 02:15:31,000 --> 02:15:32,800 and develop treatments. 2599 02:15:32,800 --> 02:15:35,080 And so with that, I'm going to hand it off 2600 02:15:35,080 --> 02:15:39,800 to Dr. Vicky Johnson from the University of Pennsylvania. 2601 02:15:39,800 --> 02:15:41,640 -Thanks, Dirk. Hi, everyone, 2602 02:15:41,640 --> 02:15:43,760 and thank you, also, to the organizers. 2603 02:15:43,760 --> 02:15:47,680 It's a pleasure to be here and participate in this summit. 2604 02:15:47,680 --> 02:15:49,200 Next slide, please. 2605 02:15:49,200 --> 02:15:53,760 So first, I don't have any disclosures, 2606 02:15:53,760 --> 02:15:56,920 and I'm going to talk about recommendation for Priority 4. 2607 02:15:56,920 --> 02:16:00,360 Which is to promote the basic translational research 2608 02:16:00,360 --> 02:16:03,480 to elucidate the mechanistic pathways, development, 2609 02:16:03,480 --> 02:16:07,320 and progression of post-TBI AD/ADRD neuropathologies. 2610 02:16:07,320 --> 02:16:10,160 And their associations with clinical symptoms. 2611 02:16:10,160 --> 02:16:13,080 Next slide, please. So I'm just going to start 2612 02:16:13,080 --> 02:16:14,840 with a little bit of background about TBI. 2613 02:16:14,840 --> 02:16:16,520 And some of the important considerations 2614 02:16:16,520 --> 02:16:18,800 that are going to be necessary in understanding 2615 02:16:18,800 --> 02:16:22,280 how TBI might ultimately lead to neurodegeneration. 2616 02:16:22,280 --> 02:16:25,040 So TBI is caused by some mechanical event 2617 02:16:25,040 --> 02:16:26,800 resulting in trauma to the brain. 2618 02:16:26,800 --> 02:16:29,720 We often talk about it like it's one disease, one disorder, 2619 02:16:29,720 --> 02:16:32,440 but in reality, the acute pathologies of TBI 2620 02:16:32,440 --> 02:16:34,800 are really very diverse and complex. 2621 02:16:34,800 --> 02:16:39,200 And you can see here some examples of different CT scans, 2622 02:16:39,200 --> 02:16:42,840 all with displaying very different types of injuries. 2623 02:16:42,840 --> 02:16:44,960 But importantly, all falling into that category 2624 02:16:44,960 --> 02:16:47,080 of severe TBI. 2625 02:16:47,080 --> 02:16:48,920 There's also a spectrum of severity. 2626 02:16:48,920 --> 02:16:50,720 We've heard about repetitive mild TBI 2627 02:16:50,720 --> 02:16:54,000 as a risk factor for later neurodegeneration. 2628 02:16:54,000 --> 02:16:57,200 And the pathophysiology of or what's happening in the brain 2629 02:16:57,200 --> 02:16:59,200 in mild TBI even acutely 2630 02:16:59,200 --> 02:17:02,000 and even following very low-level repetitive exposures 2631 02:17:02,000 --> 02:17:05,120 is something that's far less-well understood. 2632 02:17:05,120 --> 02:17:07,400 So in summation, TBI is really heterogeneous 2633 02:17:07,400 --> 02:17:13,080 with a wide spectrum in both the nature and severity of injury. 2634 02:17:13,080 --> 02:17:15,720 Next slide, please. So what we do know, 2635 02:17:15,720 --> 02:17:18,040 at least in the more severe forms of injury, 2636 02:17:18,040 --> 02:17:19,800 is that there are evolving pathologies 2637 02:17:19,800 --> 02:17:21,680 over a temporal course. 2638 02:17:21,680 --> 02:17:23,480 There are the acute primary pathologies 2639 02:17:23,480 --> 02:17:25,600 directly related to the mechanical injury. 2640 02:17:25,600 --> 02:17:28,680 For example, this might be direct perturbation 2641 02:17:28,680 --> 02:17:30,280 of the vasculature 2642 02:17:30,280 --> 02:17:33,400 resulting in hemorrhage or direct injury to neurons 2643 02:17:33,400 --> 02:17:35,920 and axons causing things like traumatic axonal injury. 2644 02:17:35,920 --> 02:17:37,800 And what we know is that this can lead 2645 02:17:37,800 --> 02:17:41,360 to really very complex and diverse secondary pathologies. 2646 02:17:41,360 --> 02:17:44,280 And these some of which are listed here of being studied 2647 02:17:44,280 --> 02:17:47,800 over many years both clinically and experimentally. 2648 02:17:47,800 --> 02:17:49,200 And what we've come to appreciate 2649 02:17:49,200 --> 02:17:51,280 is that some of these secondary processes 2650 02:17:51,280 --> 02:17:53,760 can occur over many weeks 2651 02:17:53,760 --> 02:17:57,360 and really quite protracted periods of time post-injury. 2652 02:17:57,360 --> 02:18:00,120 And then, of course, what we're interested in here today 2653 02:18:00,120 --> 02:18:03,080 is that some of these individuals, certainly not all, 2654 02:18:03,080 --> 02:18:08,880 who have chronic pathologies, including those which are -- 2655 02:18:08,880 --> 02:18:12,600 encompass AD and ADRD-associated pathologies. 2656 02:18:12,600 --> 02:18:13,880 And I think important to remember 2657 02:18:13,880 --> 02:18:15,600 over that same time frame, 2658 02:18:15,600 --> 02:18:18,440 there may very well be processes of recovery or reorganization 2659 02:18:18,440 --> 02:18:22,320 that are also occurring in the brain in response to injury. 2660 02:18:22,320 --> 02:18:25,080 And critically, and as Kristen mentioned, 2661 02:18:25,080 --> 02:18:27,040 is perhaps what's a little bit different 2662 02:18:27,040 --> 02:18:28,520 from other neurodegenerative disease, 2663 02:18:28,520 --> 02:18:31,120 at least in the case of more severe injuries. 2664 02:18:31,120 --> 02:18:35,400 Is that we have a clear start point or time zero essentially 2665 02:18:35,400 --> 02:18:37,960 when we know that this specific event has occurred 2666 02:18:37,960 --> 02:18:39,440 and I put an individual 2667 02:18:39,440 --> 02:18:42,800 on a pathway towards delayed neurodegeneration. 2668 02:18:42,800 --> 02:18:44,320 What we don't really have a great understanding of 2669 02:18:44,320 --> 02:18:47,040 is if and how this relates to the nature, extent, 2670 02:18:47,040 --> 02:18:49,560 and evolution of these earlier pathologies. 2671 02:18:49,560 --> 02:18:54,600 Next slide. So with respect to the neuropathology, 2672 02:18:54,600 --> 02:18:57,880 there's been a lot of focus on type pathologies, 2673 02:18:57,880 --> 02:18:59,600 but I think it's important to note 2674 02:18:59,600 --> 02:19:03,160 that through various different cohorts, K series, descriptions. 2675 02:19:03,160 --> 02:19:05,880 And some individuals fall into the eye 2676 02:19:05,880 --> 02:19:09,400 of various other pathologies have been described. 2677 02:19:09,400 --> 02:19:13,080 Including amyloid-beta, TDP 43 proteinopathies, 2678 02:19:13,080 --> 02:19:16,760 vascular pathologies, chronic inflammatory processes, 2679 02:19:16,760 --> 02:19:21,600 axonal degeneration, axonal and atrophic processes in the brain. 2680 02:19:21,600 --> 02:19:23,560 And a big question around this is what we refer 2681 02:19:23,560 --> 02:19:25,640 to as the clinical pathological correlation. 2682 02:19:25,640 --> 02:19:27,600 So what aspects of these pathologies 2683 02:19:27,600 --> 02:19:28,960 are important contributors 2684 02:19:28,960 --> 02:19:31,560 to the clinical symptoms and clinical progression 2685 02:19:31,560 --> 02:19:34,200 that Kristen has so nicely described? 2686 02:19:34,200 --> 02:19:38,440 And what do these pathologies potentially interact 2687 02:19:38,440 --> 02:19:39,880 in some way? 2688 02:19:39,880 --> 02:19:41,960 And another important question is whether 2689 02:19:41,960 --> 02:19:43,800 and in what way these various pathologies 2690 02:19:43,800 --> 02:19:47,400 relate to the number, severity, and types of TBI. 2691 02:19:47,400 --> 02:19:50,160 And perhaps other factors such as age at injury. 2692 02:19:50,160 --> 02:19:55,440 So there has been some progress in this regard 2693 02:19:55,440 --> 02:19:57,800 and examining these various questions. 2694 02:19:57,800 --> 02:20:00,080 And as part of our recommendation as shown here, 2695 02:20:00,080 --> 02:20:02,200 the committee felt it's important to sort of 2696 02:20:02,200 --> 02:20:04,400 further characterize and advance our understanding 2697 02:20:04,400 --> 02:20:06,840 of how the various aspects of these pathologies. 2698 02:20:06,840 --> 02:20:08,720 And their potential interactions contribute 2699 02:20:08,720 --> 02:20:11,640 to the clinical manifestations after a TBI. 2700 02:20:11,640 --> 02:20:14,080 And importantly, also how the TBI exposure history, 2701 02:20:14,080 --> 02:20:17,080 which has its own complexities, 2702 02:20:17,080 --> 02:20:20,320 influences the nature and extent of those pathologies. 2703 02:20:20,320 --> 02:20:23,240 Next slide. 2704 02:20:23,240 --> 02:20:26,200 So as I mentioned, there's been a lot of focus on tau. 2705 02:20:26,200 --> 02:20:27,920 This was something that was first really described 2706 02:20:27,920 --> 02:20:31,440 in postmortem examinations of former boxers many years ago. 2707 02:20:31,440 --> 02:20:32,920 As you can see an example of that 2708 02:20:32,920 --> 02:20:35,120 from one of these early papers on the left. 2709 02:20:35,120 --> 02:20:37,600 And then was later described in various cohorts since, 2710 02:20:37,600 --> 02:20:40,800 including other participants of contact sports, 2711 02:20:40,800 --> 02:20:43,800 more severe forms of injury earlier referred to 2712 02:20:43,800 --> 02:20:46,560 as dementia pugilistica specific to boxers. 2713 02:20:46,560 --> 02:20:49,960 And later, the term chronic traumatic encephalopathy, 2714 02:20:49,960 --> 02:20:51,400 or CTE [Indistinct]. 2715 02:20:51,400 --> 02:20:54,240 So various aspects of these pathologies, 2716 02:20:54,240 --> 02:21:01,560 and you can see here the paper of the recent consensus meeting. 2717 02:21:01,560 --> 02:21:05,080 Various aspects of these pathologies have been described 2718 02:21:05,080 --> 02:21:06,920 as being potentially distinct 2719 02:21:06,920 --> 02:21:09,680 in their morphologies and distributions. 2720 02:21:09,680 --> 02:21:11,400 And, therefore, considered just possibly useful 2721 02:21:11,400 --> 02:21:15,200 diagnostically in distinguishing TBI-related neurodegeneration 2722 02:21:15,200 --> 02:21:18,360 from that of other neurodegenerative disease. 2723 02:21:18,360 --> 02:21:22,560 And this was the papers that outlining 2724 02:21:22,560 --> 02:21:24,960 this pathognomonic CTE lesion that came out of that 2725 02:21:24,960 --> 02:21:29,080 NINDS-funded consensus efforts to define CTE 2726 02:21:29,080 --> 02:21:31,840 and these type pathologies following TBI. 2727 02:21:31,840 --> 02:21:35,520 And describes the depths of critical sulci region. 2728 02:21:35,520 --> 02:21:38,600 So and next slide, please. 2729 02:21:38,600 --> 02:21:42,080 So there really has been limited characterizer 2730 02:21:42,080 --> 02:21:45,480 over the broader spectrum of post-TBI pathologies 2731 02:21:45,480 --> 02:21:46,800 that have been described 2732 02:21:46,800 --> 02:21:48,480 including some of those described 2733 02:21:48,480 --> 02:21:50,200 as being potentially specific to trauma. 2734 02:21:50,200 --> 02:21:52,600 And in particular how they may be similar 2735 02:21:52,600 --> 02:21:55,400 or different to other pathologies observed 2736 02:21:55,400 --> 02:21:57,080 and other neurodegenerative disease 2737 02:21:57,080 --> 02:22:00,640 and perhaps better established neurodegenerative disease. 2738 02:22:00,640 --> 02:22:02,480 And there's been some emerging reports 2739 02:22:02,480 --> 02:22:04,040 that have started using advanced technologies, 2740 02:22:04,040 --> 02:22:06,240 proteomic RNA-sequencing technologies, 2741 02:22:06,240 --> 02:22:09,040 to begin to further characterize this. 2742 02:22:09,040 --> 02:22:11,160 There's also been studies that, including by our group, 2743 02:22:11,160 --> 02:22:13,560 to try and look at the differences using 2744 02:22:13,560 --> 02:22:18,080 immunohistochemistry directly by comparing to other disease. 2745 02:22:18,080 --> 02:22:19,720 And then some also some interesting work 2746 02:22:19,720 --> 02:22:21,600 you can see on this paper on the right here 2747 02:22:21,600 --> 02:22:23,960 from the group in Cambridge 2748 02:22:23,960 --> 02:22:25,400 looking at small series of cases. 2749 02:22:25,400 --> 02:22:27,120 And showing potentially unique aspects 2750 02:22:27,120 --> 02:22:32,200 in the structure of tau in CTE as identified using cryo-EM. 2751 02:22:32,200 --> 02:22:34,600 But certainly direct further comparisons 2752 02:22:34,600 --> 02:22:36,760 with other types of neurodegenerative disease. 2753 02:22:36,760 --> 02:22:40,640 And these will offer potentially important information 2754 02:22:40,640 --> 02:22:43,000 relevant to both diagnoses, 2755 02:22:43,000 --> 02:22:46,320 as well as offering potential mechanistic insights. 2756 02:22:46,320 --> 02:22:49,720 So as such, the committee has included recommendations 2757 02:22:49,720 --> 02:22:52,000 to apply both traditional and advanced approaches 2758 02:22:52,000 --> 02:22:55,680 to really deeply characterize these post-TBI neuropathologies. 2759 02:22:55,680 --> 02:22:58,240 And comparative analysis with other NEDs 2760 02:22:58,240 --> 02:23:01,640 and neurodegenerative disorders. Next slide. 2761 02:23:04,000 --> 02:23:07,320 So with this diversity of and complexity 2762 02:23:07,320 --> 02:23:09,600 of the clinical and neuropathological, it comes -- 2763 02:23:09,600 --> 02:23:12,160 it starts to present obvious challenges 2764 02:23:12,160 --> 02:23:13,920 when we start to think about how to model 2765 02:23:13,920 --> 02:23:17,680 these processes experimentally. Now there is an experiment 2766 02:23:17,680 --> 02:23:19,400 established in literature on this. 2767 02:23:19,400 --> 02:23:22,400 Where various groups have worked to see if they can introduce -- 2768 02:23:22,400 --> 02:23:24,320 induce these neurodegenerative pathologies 2769 02:23:24,320 --> 02:23:26,320 and experimental TBI models, 2770 02:23:26,320 --> 02:23:30,080 mostly with a focus on tau and amyloid-beta. 2771 02:23:30,080 --> 02:23:31,720 And while we don't have time to go into 2772 02:23:31,720 --> 02:23:34,840 that whole literature in detail, to sort of summarize it 2773 02:23:34,840 --> 02:23:37,280 and saying that it really encompasses various models, 2774 02:23:37,280 --> 02:23:40,000 established models, the vast majority in rodents, 2775 02:23:40,000 --> 02:23:42,400 both with and without inoculated genetic backgrounds 2776 02:23:42,400 --> 02:23:46,040 and considerable diversity in the sort of mechanics, 2777 02:23:46,040 --> 02:23:49,280 and severity, and approach to injury applied. 2778 02:23:49,280 --> 02:23:51,280 There's also been various outcome measures 2779 02:23:51,280 --> 02:23:53,840 that have been examined, some using immunohistochemistry 2780 02:23:53,840 --> 02:23:55,520 to look at pathology, for example. 2781 02:23:55,520 --> 02:23:57,480 Others looking at biochemical outcome, 2782 02:23:57,480 --> 02:24:00,840 biochemistry as an outcome, looking at changes 2783 02:24:00,840 --> 02:24:03,000 and quantification of cross-correlated tau. 2784 02:24:03,000 --> 02:24:06,080 So perhaps not surprisingly, there's been a large range 2785 02:24:06,080 --> 02:24:08,800 in the results from those where you can see 2786 02:24:08,800 --> 02:24:12,560 and some examples of this work here. 2787 02:24:12,560 --> 02:24:15,880 Those where there was observed changes in tau amyloid 2788 02:24:15,880 --> 02:24:17,600 to those where trauma did not result 2789 02:24:17,600 --> 02:24:19,800 in the presence of pathology. 2790 02:24:19,800 --> 02:24:22,360 And even some studies where a regression of pathology 2791 02:24:22,360 --> 02:24:26,320 was seen in models where there was predisposition. 2792 02:24:26,320 --> 02:24:28,680 So next slide, please. 2793 02:24:28,680 --> 02:24:32,880 So the committee agreed that really further development 2794 02:24:32,880 --> 02:24:35,200 of consistent and reproducible models 2795 02:24:35,200 --> 02:24:37,400 that are clinically relevant. Is going to be really important 2796 02:24:37,400 --> 02:24:40,760 advancing our understanding of how and why TBI might be able 2797 02:24:40,760 --> 02:24:43,440 to contribute to neurodegenerative processes. 2798 02:24:43,440 --> 02:24:45,600 With the recognition that various aspects of this 2799 02:24:45,600 --> 02:24:47,200 are challenging. 2800 02:24:47,200 --> 02:24:50,200 Models that accurately reproduce real-world biomechanics 2801 02:24:50,200 --> 02:24:52,280 of injury is going to be important 2802 02:24:52,280 --> 02:24:56,160 and these are obviously extremely diverse and complex. 2803 02:24:56,160 --> 02:24:59,120 Various aspects of preclinical models 2804 02:24:59,120 --> 02:25:00,920 add to the challenges 2805 02:25:00,920 --> 02:25:02,920 of recapitulating those biomechanics, 2806 02:25:02,920 --> 02:25:04,480 things like anatomic differences, 2807 02:25:04,480 --> 02:25:06,840 brain size, weight matter volumes. 2808 02:25:06,840 --> 02:25:08,200 And of course, we know 2809 02:25:08,200 --> 02:25:09,920 that aspects of gyrencephalic structure, 2810 02:25:09,920 --> 02:25:11,320 these depth of cell site pathologies 2811 02:25:11,320 --> 02:25:13,200 seem to be important. 2812 02:25:13,200 --> 02:25:16,400 So gyrencephalic structure is something of consideration 2813 02:25:16,400 --> 02:25:18,960 when thinking about our models. 2814 02:25:18,960 --> 02:25:20,440 Of course, we're talking about pathologies 2815 02:25:20,440 --> 02:25:23,000 that regress over the order of years, 2816 02:25:23,000 --> 02:25:24,560 lifespan may be important. 2817 02:25:24,560 --> 02:25:26,760 And finally, I'll just sort of mention very briefly 2818 02:25:26,760 --> 02:25:28,800 in vitro models which have their own complexity 2819 02:25:28,800 --> 02:25:32,120 when it comes to biomechanics. But may play an important role 2820 02:25:32,120 --> 02:25:35,320 in addressing specific mechanistic questions. 2821 02:25:35,320 --> 02:25:37,880 Next slide. 2822 02:25:37,880 --> 02:25:39,640 So we're dealing with these complex 2823 02:25:39,640 --> 02:25:42,560 and heterogeneous pathologies over a long temporal course. 2824 02:25:42,560 --> 02:25:45,000 And our group felt with the data, the human data, 2825 02:25:45,000 --> 02:25:47,000 which is still very much being characterized. 2826 02:25:47,000 --> 02:25:50,000 And we've heard of the efforts to do that, 2827 02:25:50,000 --> 02:25:54,120 including data such as biomechanics data, 2828 02:25:54,120 --> 02:25:56,520 neuropathology data, clinical phenotyping data. 2829 02:25:56,520 --> 02:25:58,240 Are going to be really critical for further 2830 02:25:58,240 --> 02:26:01,000 developing our quantic phase models of TBI 2831 02:26:01,000 --> 02:26:02,920 and to inform us really what is important 2832 02:26:02,920 --> 02:26:05,440 to be modeling and to be relevant. 2833 02:26:05,440 --> 02:26:08,320 And then, it's likely that a range of models 2834 02:26:08,320 --> 02:26:11,360 will be helpful in addressing specific questions. 2835 02:26:11,360 --> 02:26:13,120 And of course, the infrastructure building 2836 02:26:13,120 --> 02:26:16,880 that's being described and Recommendations 1, 2, and 3 2837 02:26:16,880 --> 02:26:19,440 are going to be critical for facilitating those mechanistic 2838 02:26:19,440 --> 02:26:22,040 and translational priorities. 2839 02:26:22,040 --> 02:26:26,080 So here, the recommendation was to really promote collaboration, 2840 02:26:26,080 --> 02:26:27,680 as Dirk sort of mentioned, 2841 02:26:27,680 --> 02:26:30,040 as well, between clinical and translational researchers 2842 02:26:30,040 --> 02:26:31,520 to accelerate the development 2843 02:26:31,520 --> 02:26:34,560 of these clinically-relevant TBI models. 2844 02:26:34,560 --> 02:26:38,680 And my last slide here, if we move forward one, 2845 02:26:38,680 --> 02:26:41,800 is just to mention this idea of resilience. 2846 02:26:41,800 --> 02:26:44,920 We know that many people with a history of trauma TBI, 2847 02:26:44,920 --> 02:26:47,200 including even very severe injuries 2848 02:26:47,200 --> 02:26:50,400 or highly-repetitive exposures, for example, in boxers. 2849 02:26:50,400 --> 02:26:53,440 Don't develop CTE or trauma- related neurodegeneration 2850 02:26:53,440 --> 02:26:55,560 or progressive decline. 2851 02:26:55,560 --> 02:26:57,440 And understanding why this might be might 2852 02:26:57,440 --> 02:26:58,800 be helpful and informative. 2853 02:26:58,800 --> 02:27:01,160 And we can think about that in several ways. 2854 02:27:01,160 --> 02:27:02,800 There may be people who just by exposure 2855 02:27:02,800 --> 02:27:05,640 are resistant to developing the pathology, 2856 02:27:05,640 --> 02:27:09,800 and thus, the clinical decline that comes with it. 2857 02:27:09,800 --> 02:27:12,000 And there are possible genetic environmental factors 2858 02:27:12,000 --> 02:27:13,800 that then contribute to them. 2859 02:27:13,800 --> 02:27:15,320 And secondly, there may be individuals 2860 02:27:15,320 --> 02:27:17,720 that demonstrate resilience to the clinical symptoms 2861 02:27:17,720 --> 02:27:21,320 despite having TDI-related neurodegenerative pathologies. 2862 02:27:21,320 --> 02:27:23,120 And this brings the idea of reserve 2863 02:27:23,120 --> 02:27:25,200 or pre-morbid factors that might influence 2864 02:27:25,200 --> 02:27:28,000 the clinical trajectory in some people. 2865 02:27:28,000 --> 02:27:31,440 So we really know very little about this and TBI, 2866 02:27:31,440 --> 02:27:33,560 and it's certainly challenging to examine, 2867 02:27:33,560 --> 02:27:35,600 and particularly, as Kristen noted, 2868 02:27:35,600 --> 02:27:39,280 the -- in the latter scenario, when looking at clinical data. 2869 02:27:39,280 --> 02:27:42,240 We don't have enough complex data clinical impairments 2870 02:27:42,240 --> 02:27:44,520 and possibly in recovery related to injury 2871 02:27:44,520 --> 02:27:47,720 to disentangle from any progressive changes. 2872 02:27:47,720 --> 02:27:50,920 So longitudinal studies will obviously be important. 2873 02:27:50,920 --> 02:27:53,600 So nonetheless, understanding these processes 2874 02:27:53,600 --> 02:27:55,080 may be important in contributing 2875 02:27:55,080 --> 02:27:57,960 to our understanding of mechanisms of disease. 2876 02:27:57,960 --> 02:27:59,640 So as shown here, the committee included 2877 02:27:59,640 --> 02:28:02,600 the identification of intrinsic and environmental factors 2878 02:28:02,600 --> 02:28:07,000 and that confer resilience as our final recommendation. 2879 02:28:07,000 --> 02:28:10,400 So thank you, and I will pass back over to Kristen 2880 02:28:10,400 --> 02:28:13,800 for our question and answer session. 2881 02:28:13,800 --> 02:28:17,840 -Great, thank you to Vicky and to Dirk for those great talks. 2882 02:28:17,840 --> 02:28:19,880 If you could go to the next slide. 2883 02:28:21,920 --> 02:28:24,480 Thank you. So our primary goal today 2884 02:28:24,480 --> 02:28:27,800 really is to seek feedback on these recommendations 2885 02:28:27,800 --> 02:28:30,200 to really ensure that they're consistent 2886 02:28:30,200 --> 02:28:34,440 with and reflective of the stakeholder priorities. 2887 02:28:34,440 --> 02:28:36,840 That many of our attendees today represent. 2888 02:28:36,840 --> 02:28:39,120 So let's start. 2889 02:28:39,120 --> 02:28:42,000 I see a question from Mr. Ellenbogen. 2890 02:28:44,600 --> 02:28:47,160 -Thank you so much. 2891 02:28:47,160 --> 02:28:49,800 I was unable to speak at the earlier session 2892 02:28:49,800 --> 02:28:51,360 and just wanted to add one comment 2893 02:28:51,360 --> 02:28:56,840 before I go into my TBI comment. 2894 02:28:56,840 --> 02:28:59,320 I will have to say that detection 2895 02:28:59,320 --> 02:29:02,000 is a very complicated matter. 2896 02:29:02,000 --> 02:29:04,840 And as a person living with this disease, 2897 02:29:04,840 --> 02:29:09,200 I may not want someone to know I have some kind of dementia. 2898 02:29:09,200 --> 02:29:11,600 The second thing, add some type of dementia 2899 02:29:11,600 --> 02:29:13,520 on your medical record, 2900 02:29:13,520 --> 02:29:17,160 I instantly have my rights taken away from me. 2901 02:29:17,160 --> 02:29:20,000 We need to change the laws around that 2902 02:29:20,000 --> 02:29:24,400 before we expect our doctors and the people to come forward. 2903 02:29:24,400 --> 02:29:27,800 For example, I would lose driving capabilities, 2904 02:29:27,800 --> 02:29:30,280 depending on what state I'm in, 2905 02:29:30,280 --> 02:29:33,600 lose my job or get fired instantly from it, 2906 02:29:33,600 --> 02:29:37,240 or even lose insurances that I would be entitled to. 2907 02:29:37,240 --> 02:29:40,520 So there are things that need to be addressed 2908 02:29:40,520 --> 02:29:41,880 and it's very complicated. 2909 02:29:41,880 --> 02:29:43,440 It's just not as easy as just being able 2910 02:29:43,440 --> 02:29:49,360 to diagnose the disease. But as far as my TBI comment, 2911 02:29:49,360 --> 02:29:54,640 we have learned so much about ways to possibly delay dementia 2912 02:29:54,640 --> 02:29:58,320 and we now encourage that in many public ways. 2913 02:29:58,320 --> 02:30:01,920 As an expert who's living with this horrible disease, 2914 02:30:01,920 --> 02:30:05,240 I would not wish this on my worst enemy. 2915 02:30:05,240 --> 02:30:07,600 What I cannot understand, though, 2916 02:30:07,600 --> 02:30:11,880 is that we have learned so much about TBI, 2917 02:30:11,880 --> 02:30:15,880 yet we don't do much to educate our children 2918 02:30:15,880 --> 02:30:18,720 to no longer play games such as football. 2919 02:30:18,720 --> 02:30:21,160 We clearly know that this will increase their risk 2920 02:30:21,160 --> 02:30:22,760 to brain damage. 2921 02:30:22,760 --> 02:30:25,720 Why don't we make this very public 2922 02:30:25,720 --> 02:30:28,520 so at least these folks have a chance? 2923 02:30:28,520 --> 02:30:31,800 Thank you. 2924 02:30:31,800 --> 02:30:33,440 -Thank you, Mr. Ellenbogen. 2925 02:30:33,440 --> 02:30:37,160 You, again, raise such an important point. 2926 02:30:37,160 --> 02:30:40,120 So what I'm hearing is that we need to consider 2927 02:30:40,120 --> 02:30:42,800 in our recommendations, and our colleagues, 2928 02:30:42,800 --> 02:30:47,040 and across the multiple etiology dementia subgroups. 2929 02:30:47,040 --> 02:30:51,040 The potential consequences of detection and diagnosis 2930 02:30:51,040 --> 02:30:54,640 to those living with dementia, with traumatic brain injury. 2931 02:30:54,640 --> 02:30:57,200 And I'm also hearing a need to for us 2932 02:30:57,200 --> 02:31:02,040 to consider the post-TBI ADRD group 2933 02:31:02,040 --> 02:31:06,000 expanding our efforts to educate the public 2934 02:31:06,000 --> 02:31:08,680 about the potential sequelae of traumatic brain injury. 2935 02:31:08,680 --> 02:31:13,080 So that people can make evidence-based decisions 2936 02:31:13,080 --> 02:31:16,800 about their individual risk tolerance. 2937 02:31:16,800 --> 02:31:21,160 Very well-taken point. Thank you for that. 2938 02:31:21,160 --> 02:31:23,520 Let's see, Dr. Schneider, I see a question. 2939 02:31:27,240 --> 02:31:28,840 -Hi, Kristen. 2940 02:31:28,840 --> 02:31:31,920 Thank you for the -- those great presentations. 2941 02:31:31,920 --> 02:31:36,120 I had a question about Recommendation Number 2, 2942 02:31:36,120 --> 02:31:39,640 which is the clinical heterogeneity 2943 02:31:39,640 --> 02:31:43,800 and the need for more clinical characterization. 2944 02:31:43,800 --> 02:31:48,440 And I'm just wondering whether or not the biomarker component 2945 02:31:48,440 --> 02:31:51,880 should be brought to the top of that list. 2946 02:31:51,880 --> 02:31:54,520 Because as we know in dementia, 2947 02:31:54,520 --> 02:31:56,000 you know, in all these dementias, 2948 02:31:56,000 --> 02:31:59,240 there's so much heterogeneity in what we see. 2949 02:31:59,240 --> 02:32:01,440 And, you know, do we really expect 2950 02:32:01,440 --> 02:32:05,800 that there's going to be a single clinical feature 2951 02:32:05,800 --> 02:32:08,040 that's going to tell us something different? 2952 02:32:08,040 --> 02:32:11,800 I mean, I think we should certainly be looking, 2953 02:32:11,800 --> 02:32:15,600 but wouldn't it, like the other diseases, 2954 02:32:15,600 --> 02:32:18,240 be more important to have a biomarker, 2955 02:32:18,240 --> 02:32:19,680 something that tells us 2956 02:32:19,680 --> 02:32:22,680 that there's actually been injury to the brain. 2957 02:32:22,680 --> 02:32:27,960 And so just your thoughts on that second recommendation 2958 02:32:27,960 --> 02:32:31,600 and the elevation perhaps of biomarkers. 2959 02:32:31,600 --> 02:32:33,720 -That's a great thought. 2960 02:32:33,720 --> 02:32:36,880 Dr. Henrik Zetterberg, do you have thoughts on that, 2961 02:32:36,880 --> 02:32:39,760 the potential elevation of biological markers 2962 02:32:39,760 --> 02:32:42,280 within Recommendation 2? 2963 02:32:42,280 --> 02:32:44,760 -Yes, I think definitely it can be included 2964 02:32:44,760 --> 02:32:46,320 and we should also separate them, 2965 02:32:46,320 --> 02:32:48,640 the acute phase of TBI with the more chronic phase. 2966 02:32:48,640 --> 02:32:52,800 And perhaps also address what happens in repetitive TBIs 2967 02:32:52,800 --> 02:32:55,280 and how one with biomarks could follow 2968 02:32:55,280 --> 02:33:00,680 sort of the amount of injury to the brain tissue 2969 02:33:00,680 --> 02:33:03,560 using the existing biomarkers. 2970 02:33:03,560 --> 02:33:07,320 But we would also need to develop new biomarkers 2971 02:33:07,320 --> 02:33:10,360 because the tau that is seen in chronic TBI, 2972 02:33:10,360 --> 02:33:14,440 for example, is not possible to detect the monitor 2973 02:33:14,440 --> 02:33:18,600 using the existing fluid biomarkers for tau pathogen. 2974 02:33:18,600 --> 02:33:20,000 And the imaging biomarker data 2975 02:33:20,000 --> 02:33:22,080 will also need to become different. 2976 02:33:22,080 --> 02:33:26,800 So it's almost like we perhaps should try to also emphasize 2977 02:33:26,800 --> 02:33:30,480 that we need to also develop and validate biomarkers 2978 02:33:30,480 --> 02:33:35,040 for TBI-related brain tissue changes. 2979 02:33:35,040 --> 02:33:37,240 So basically what I'm trying to say 2980 02:33:37,240 --> 02:33:40,800 is that we can't just lean back and use existing biomarkers, 2981 02:33:40,800 --> 02:33:46,160 also, because they might not represent 2982 02:33:46,160 --> 02:33:49,000 the TBI-related pathogens completely. 2983 02:33:49,000 --> 02:33:50,320 But acute accelerator injury 2984 02:33:50,320 --> 02:33:53,200 and [Indistinct] calculation works. 2985 02:33:53,200 --> 02:33:55,040 There the biomarkers works -- 2986 02:33:55,040 --> 02:33:59,960 work across the different types of TBI 2987 02:33:59,960 --> 02:34:03,240 and also we can make use of them developed 2988 02:34:03,240 --> 02:34:06,360 for Neurodegenerative dementias. 2989 02:34:06,360 --> 02:34:08,080 -Thank you, Henrik. 2990 02:34:08,080 --> 02:34:09,800 Pratik, I wander if you have any comments about this, too, 2991 02:34:09,800 --> 02:34:11,480 with respect to imaging biomarkers. 2992 02:34:11,480 --> 02:34:15,160 So part of Julie's point is that we do not expect 2993 02:34:15,160 --> 02:34:19,680 to see one isolated biomarker but perhaps panels of biomarkers 2994 02:34:19,680 --> 02:34:23,080 that we required for earliest detection. 2995 02:34:23,080 --> 02:34:25,280 -Yeah, no. I absolutely agree, you know, 2996 02:34:25,280 --> 02:34:28,720 and I think we need to emphasize capturing 2997 02:34:28,720 --> 02:34:33,320 as much data as possible from early after the injury. 2998 02:34:33,320 --> 02:34:35,400 Where we can characterize, you know, 2999 02:34:35,400 --> 02:34:38,560 the particular pathophysiological mechanism 3000 02:34:38,560 --> 02:34:42,000 operating in that particular patient. 3001 02:34:42,000 --> 02:34:43,600 So... 3002 02:34:46,200 --> 02:34:49,120 ...all of the acute TBI studies are generally set up 3003 02:34:49,120 --> 02:34:51,360 as precision medicine studies for that reason. 3004 02:34:51,360 --> 02:34:55,000 And once we've captured that data through imaging biomarkers, 3005 02:34:55,000 --> 02:34:56,840 blood specimen biomarkers, 3006 02:34:56,840 --> 02:35:00,240 then phenotyping of the clinical characteristics, 3007 02:35:00,240 --> 02:35:01,680 and cognitive function, 3008 02:35:01,680 --> 02:35:03,880 and behavioral function at that acute phase. 3009 02:35:03,880 --> 02:35:05,360 Then we can follow it longitudinally 3010 02:35:05,360 --> 02:35:07,400 and see how it evolves like the slide 3011 02:35:07,400 --> 02:35:09,240 you showed from the different studies 3012 02:35:09,240 --> 02:35:13,760 showing how different patients may have different evolution. 3013 02:35:13,760 --> 02:35:15,280 And there's certain latent classes 3014 02:35:15,280 --> 02:35:19,000 that can be discovered from that data. 3015 02:35:19,000 --> 02:35:20,440 So that's a main priority 3016 02:35:20,440 --> 02:35:22,720 of a lot of the acute TBI studies right now 3017 02:35:22,720 --> 02:35:26,800 with the qualifications for multiple years. 3018 02:35:26,800 --> 02:35:30,000 And I think that imaging is interesting, too, 3019 02:35:30,000 --> 02:35:33,720 because not only can you get a biomarker 3020 02:35:33,720 --> 02:35:36,320 of the injury pathophysiology 3021 02:35:36,320 --> 02:35:39,960 and its progression or degeneration 3022 02:35:39,960 --> 02:35:41,920 during the recovery process. 3023 02:35:41,920 --> 02:35:44,400 But there -- you can also get biomarkers 3024 02:35:44,400 --> 02:35:48,800 that may be related to innate resilience properties 3025 02:35:48,800 --> 02:35:52,920 that may account for some of the inter-individual variability 3026 02:35:52,920 --> 02:35:54,320 of the recovery process. 3027 02:35:54,320 --> 02:35:59,720 You know, despite, you know, the injury. 3028 02:35:59,720 --> 02:36:04,400 So some patients do well because they have innate resilience 3029 02:36:04,400 --> 02:36:07,200 despite a greater severity of injury 3030 02:36:07,200 --> 02:36:10,480 and others do poorly even though the injury may be considered 3031 02:36:10,480 --> 02:36:12,600 mild by standard clinical criteria. 3032 02:36:12,600 --> 02:36:15,520 We see this all the time and we don't understand 3033 02:36:15,520 --> 02:36:19,720 right now the factors that cause that variability 3034 02:36:19,720 --> 02:36:21,640 and our inability to predict, 3035 02:36:21,640 --> 02:36:23,920 you know, the longer-term outcomes. 3036 02:36:23,920 --> 02:36:26,880 So it's going to be important to characterize in the acute phase 3037 02:36:26,880 --> 02:36:30,480 both the injury pathophysiology and the resilience factors. 3038 02:36:30,480 --> 02:36:34,200 And I think that's a common theme of many of the ADRDs, 3039 02:36:34,200 --> 02:36:39,120 as well, where resilience is taking a larger role 3040 02:36:39,120 --> 02:36:43,800 in evaluating the disease progression process. 3041 02:36:43,800 --> 02:36:45,440 -That's a great point. Thank you. 3042 02:36:45,440 --> 02:36:49,800 I agree, we should further consider this as we revise. 3043 02:36:49,800 --> 02:36:51,200 Let's see, I see in the chat 3044 02:36:51,200 --> 02:36:55,000 we have a question from Dr. Bob Stern. 3045 02:36:55,000 --> 02:36:57,800 -Thanks, Kristen. Thanks to the panel 3046 02:36:57,800 --> 02:36:59,520 and all the incredible work you've been doing. 3047 02:36:59,520 --> 02:37:02,680 This is just such an amazing transformation 3048 02:37:02,680 --> 02:37:07,400 since the previous time this was brought up. 3049 02:37:07,400 --> 02:37:11,320 I just want to try to bring up a complex point 3050 02:37:11,320 --> 02:37:15,320 between chronic traumatic encephalopathy 3051 02:37:15,320 --> 02:37:20,160 and post-TBI dementia. 3052 02:37:20,160 --> 02:37:26,600 And that has to do with the acute phase of the injuries. 3053 02:37:26,600 --> 02:37:30,080 And really what it is that we're trying to measure 3054 02:37:30,080 --> 02:37:34,080 clinically biomarker and then neuropathologically. 3055 02:37:34,080 --> 02:37:38,920 That with the repetitive head impact 3056 02:37:38,920 --> 02:37:44,320 exposure over several years in individuals 3057 02:37:44,320 --> 02:37:48,040 like contact collision sport athletes. 3058 02:37:48,040 --> 02:37:53,240 There may not be a single injury that would be considered 3059 02:37:53,240 --> 02:37:55,600 a symptomatic traumatic brain injury. 3060 02:37:55,600 --> 02:37:58,040 And yet, because of that repetitive exposure, 3061 02:37:58,040 --> 02:38:03,240 there seems to be set in motion this cascade of changes 3062 02:38:03,240 --> 02:38:07,800 leading to a progressive telopathy. 3063 02:38:07,800 --> 02:38:13,000 And in that case, it is so different to try to detect, 3064 02:38:13,000 --> 02:38:17,640 and diagnose, and come up with clinical features. 3065 02:38:17,640 --> 02:38:20,200 Because there's this period of... 3066 02:38:24,000 --> 02:38:27,320 ...delay between that time of exposure to injuries 3067 02:38:27,320 --> 02:38:31,240 and then the beginning of a progressive neurodegeneration. 3068 02:38:31,240 --> 02:38:33,800 So I just want to have people try to keep that in mind 3069 02:38:33,800 --> 02:38:39,120 that we're not talking about an injury that then recovers 3070 02:38:39,120 --> 02:38:41,600 and then there can be a chronic 3071 02:38:41,600 --> 02:38:44,400 and potentially degenerative phase later. 3072 02:38:44,400 --> 02:38:48,200 When it comes to many of the cases of CTE. 3073 02:38:51,120 --> 02:38:52,800 -Excellent point. 3074 02:38:52,800 --> 02:38:54,680 So I'm hearing you say that it's not quite sufficient for us 3075 02:38:54,680 --> 02:38:57,360 to state in our recommendations that we are interested 3076 02:38:57,360 --> 02:38:59,760 in considering a broad range of exposure histories. 3077 02:38:59,760 --> 02:39:03,120 But actually investigating more carefully the distinctions 3078 02:39:03,120 --> 02:39:05,800 between the acute and chronic pathologies 3079 02:39:05,800 --> 02:39:08,200 of distinct exposure histories. 3080 02:39:08,200 --> 02:39:09,600 -That's right. -Okay. Thank you, Doctor. 3081 02:39:09,600 --> 02:39:12,520 -I think that's going to help really elucidate 3082 02:39:12,520 --> 02:39:16,000 the differential pathologies going on 3083 02:39:16,000 --> 02:39:19,440 by differentiating it at the acute phase. 3084 02:39:19,440 --> 02:39:22,360 -Great point. Thank you, Bob. 3085 02:39:22,360 --> 02:39:25,400 I see a question now from Dr. Bellgowan. 3086 02:39:28,600 --> 02:39:29,840 -Oh, yes. 3087 02:39:29,840 --> 02:39:32,080 I'll turn my camera on. Thank you. 3088 02:39:32,080 --> 02:39:37,760 So there seem to be I know the Recommendation 4 3089 02:39:37,760 --> 02:39:39,680 was about these translational models 3090 02:39:39,680 --> 02:39:45,000 and Dr. Keene showed a bridge to those models. 3091 02:39:45,000 --> 02:39:48,000 But we know that, you know, so I was -- 3092 02:39:48,000 --> 02:39:50,440 the recommendation to me is fairly unspecific 3093 02:39:50,440 --> 02:39:54,600 because, you know, TBI, there's a lot of TBI models. 3094 02:39:54,600 --> 02:39:58,200 And are you talking about developing -- 3095 02:39:58,200 --> 02:40:00,240 is there a way to develop a consensus about 3096 02:40:00,240 --> 02:40:03,000 which is going to be the most informative model to use 3097 02:40:03,000 --> 02:40:06,800 and to bring in people from the AD/ADRD community. 3098 02:40:06,800 --> 02:40:11,720 To help us choose which models might be most effective? 3099 02:40:11,720 --> 02:40:15,840 I mean, you could even look at whether we injure a mouse early 3100 02:40:15,840 --> 02:40:19,080 and then follow them over, you know, their life, 3101 02:40:19,080 --> 02:40:21,680 or we injure an aged mouse and see what happens. 3102 02:40:21,680 --> 02:40:24,120 I mean, I just see the -- 3103 02:40:24,120 --> 02:40:26,800 a proliferation of preclinical studies. 3104 02:40:26,800 --> 02:40:29,200 And I was just wondering if part of the recommendation 3105 02:40:29,200 --> 02:40:31,200 was to figure out which might be the most, 3106 02:40:31,200 --> 02:40:32,760 you know, defining which models 3107 02:40:32,760 --> 02:40:37,480 and which parameters of models would be most effective. 3108 02:40:37,480 --> 02:40:41,040 And I wrote in the chat the VA has already put together 3109 02:40:41,040 --> 02:40:44,240 a similar effort for model development 3110 02:40:44,240 --> 02:40:46,160 in traumatic brain injury in itself. 3111 02:40:46,160 --> 02:40:47,600 But I'm not sure it includes 3112 02:40:47,600 --> 02:40:49,440 the dementia component of it, really. 3113 02:40:49,440 --> 02:40:52,680 -All right, great point. 3114 02:40:52,680 --> 02:40:55,440 Dr. Johnson, would you like to speak to that? 3115 02:40:55,440 --> 02:40:58,120 -Sure, yeah. No, I think that's an important point. 3116 02:40:58,120 --> 02:41:00,880 I think one of the important points 3117 02:41:00,880 --> 02:41:02,120 that we were trying to get at 3118 02:41:02,120 --> 02:41:03,600 is obviously there's been an evolution 3119 02:41:03,600 --> 02:41:07,000 in our understanding of the human pathology. 3120 02:41:07,000 --> 02:41:09,200 Which is still very much evolving 3121 02:41:09,200 --> 02:41:11,560 and being characterized. 3122 02:41:11,560 --> 02:41:16,520 And part of that recommendation was to really -- 3123 02:41:16,520 --> 02:41:18,920 so and I think that was what Dirk was getting to. 3124 02:41:18,920 --> 02:41:20,600 Was the picture of the bridge, as well, 3125 02:41:20,600 --> 02:41:24,400 is really that essentially collaboration 3126 02:41:24,400 --> 02:41:28,080 between preclinical and clinical work. 3127 02:41:28,080 --> 02:41:31,880 And there are pathology-based studies to really inform 3128 02:41:31,880 --> 02:41:35,400 what aspects of these models are relevant 3129 02:41:35,400 --> 02:41:38,960 and even potentially to different populations. 3130 02:41:38,960 --> 02:41:40,520 I think there's a lot of work to be done 3131 02:41:40,520 --> 02:41:43,160 even to be further characterized into the chronic phase 3132 02:41:43,160 --> 02:41:46,840 in many of the existing models. 3133 02:41:46,840 --> 02:41:49,160 But, you know, many of these models 3134 02:41:49,160 --> 02:41:51,640 are going to be useful in different respects 3135 02:41:51,640 --> 02:41:55,640 for looking at specific phenotypes of injury 3136 02:41:55,640 --> 02:41:57,640 and how they evolve into the chronic phase. 3137 02:41:57,640 --> 02:42:02,120 So I think we were really getting at the sort of the gap 3138 02:42:02,120 --> 02:42:04,800 in information between the clinical and preclinical. 3139 02:42:04,800 --> 02:42:09,200 That's going to be really important for driving our -- 3140 02:42:09,200 --> 02:42:12,000 the sort of further characterization development 3141 02:42:12,000 --> 02:42:15,720 and utility of those models. 3142 02:42:15,720 --> 02:42:18,400 -Thank you. Okay, so we will make sure -- 3143 02:42:18,400 --> 02:42:19,840 we'll take that back to the committee 3144 02:42:19,840 --> 02:42:21,600 and make sure that we discuss and clarify that. 3145 02:42:21,600 --> 02:42:26,960 Thanks, Vicky. Let's see, Dr. Hoffman, I see hand raised. 3146 02:42:26,960 --> 02:42:28,440 -Yeah. 3147 02:42:28,440 --> 02:42:33,400 Thank you, Dr. Bellgowan for that shout out, there. 3148 02:42:33,400 --> 02:42:38,200 Yeah, we're -- the VA's working with the other agencies, DOD, 3149 02:42:38,200 --> 02:42:48,440 NIH, different institutes of NIH, like NIA and NINDS. 3150 02:42:48,440 --> 02:42:52,280 To develop these -- a categorization 3151 02:42:52,280 --> 02:42:55,920 and standardization of animal models. 3152 02:42:55,920 --> 02:43:00,080 And since the VA doesn't look at acute injury. 3153 02:43:00,080 --> 02:43:03,280 We have veterans who've had brain injuries. 3154 02:43:03,280 --> 02:43:05,640 Sometimes we don't know what time zero is. 3155 02:43:05,640 --> 02:43:13,400 So having models that can show the pathological progression 3156 02:43:13,400 --> 02:43:16,080 of one or more brain injuries 3157 02:43:16,080 --> 02:43:19,960 is something that is a goal of that initiative 3158 02:43:19,960 --> 02:43:24,600 which is called precise TBI. Thank you. 3159 02:43:24,600 --> 02:43:26,560 -Thank you, Stu. 3160 02:43:26,560 --> 02:43:29,880 Okay, Dr. Corriveau, I think to turn it back to you. 3161 02:43:32,440 --> 02:43:37,160 -Okay. Thank you so much for a wonderful session 3162 02:43:37,160 --> 02:43:38,640 and lively discussion 3163 02:43:38,640 --> 02:43:41,320 including specifics about the recommendations. 3164 02:43:41,320 --> 02:43:43,440 We really appreciate that. 3165 02:43:43,440 --> 02:43:46,760 So with no further ado, I would like to -- 3166 02:43:46,760 --> 02:43:50,520 I'll -- to introduce Dr. Julie Schneider, 3167 02:43:50,520 --> 02:43:56,000 the scientific chair of the Late Committee for TDP 34 -- 3168 02:43:56,000 --> 02:44:01,800 TDP 43 Pathology and Common Late-Onset Dementias. Thank you. 3169 02:44:01,800 --> 02:44:04,640 -Thank you, Rod, and thank you to the organizers 3170 02:44:04,640 --> 02:44:09,600 for inviting me. And I apologize 3171 02:44:09,600 --> 02:44:12,040 that you have to listen to me instead of have lunch, 3172 02:44:12,040 --> 02:44:15,480 because I thought there was a break, too. 3173 02:44:15,480 --> 02:44:17,080 Next slide. 3174 02:44:21,080 --> 02:44:24,920 Again, the views expressed in these presentations are not -- 3175 02:44:24,920 --> 02:44:27,800 are those of the authors and not of the NIH. 3176 02:44:27,800 --> 02:44:31,560 I'm listing all the disclosures here, both mine, Dr. Wolk, 3177 02:44:31,560 --> 02:44:35,760 and Dr. Gitcho, who will also be speaking, 3178 02:44:35,760 --> 02:44:39,520 so we don't have to each do it on our own. 3179 02:44:39,520 --> 02:44:41,320 Next slide. 3180 02:44:41,320 --> 02:44:44,800 I want to thank the committee members Konstantinos Arfanakis, 3181 02:44:44,800 --> 02:44:46,920 Maria Corrada, Michael Gitcho, 3182 02:44:46,920 --> 02:44:51,080 Brian Kraemer, Pete Nelson, David Wolk, Hyun-Sik Yang; 3183 02:44:51,080 --> 02:44:54,400 and our cross committee members, Donna Wilcock and Dirk Keene. 3184 02:44:54,400 --> 02:44:56,160 We had lively discussions 3185 02:44:56,160 --> 02:45:00,600 and I think just a really good working group of people. 3186 02:45:00,600 --> 02:45:01,960 Everyone pitched in. 3187 02:45:01,960 --> 02:45:04,080 And thank you to the NIH staff too. 3188 02:45:04,080 --> 02:45:07,240 Next slide. 3189 02:45:07,240 --> 02:45:10,000 So I'm going to give you an introduction 3190 02:45:10,000 --> 02:45:13,400 and then briefly talk about a couple new recommendations. 3191 02:45:13,400 --> 02:45:14,880 I'm going to tell you -- 3192 02:45:14,880 --> 02:45:17,880 tell you what is LATE, why do we -- what is -- 3193 02:45:17,880 --> 02:45:20,400 what are we calling LATE? Why is it important? 3194 02:45:20,400 --> 02:45:22,720 And that's going to be followed up with Dr. Wolk, 3195 02:45:22,720 --> 02:45:24,800 who's going to give you a lot more information 3196 02:45:24,800 --> 02:45:28,000 on why LATE is important. 3197 02:45:28,000 --> 02:45:33,720 We, like the TBI session, we were new to the ADRD summit 3198 02:45:33,720 --> 02:45:38,360 as a emerging topic in the 2019 Summit. 3199 02:45:38,360 --> 02:45:42,200 And we've really come a long way. 3200 02:45:42,200 --> 02:45:45,280 Our initial recommendations involved biomarkers, 3201 02:45:45,280 --> 02:45:49,400 clinical manifestations, basic science, and pathology. 3202 02:45:49,400 --> 02:45:52,680 And we're going to continue with our push for biomarkers 3203 02:45:52,680 --> 02:45:55,640 and basic science, which are really, 3204 02:45:55,640 --> 02:45:59,360 really needed in LATE research. 3205 02:45:59,360 --> 02:46:01,720 But we're going to pivot a little bit 3206 02:46:01,720 --> 02:46:06,040 with the clinical and pathology recommendations 3207 02:46:06,040 --> 02:46:10,160 and really expand that to two completely new recommendations 3208 02:46:10,160 --> 02:46:12,120 with specific topics 3209 02:46:12,120 --> 02:46:14,840 that include clinical and pathology 3210 02:46:14,840 --> 02:46:17,400 but go beyond that to -- 3211 02:46:17,400 --> 02:46:21,840 and discuss or investigates the boundaries 3212 02:46:21,840 --> 02:46:24,360 with other diseases in the intersections 3213 02:46:24,360 --> 02:46:27,360 with hippocampal sclerosis, vascular disease, and age. 3214 02:46:27,360 --> 02:46:30,680 And I'll talk about those in just a little bit. 3215 02:46:30,680 --> 02:46:36,240 Next slide. So when we talk about LATE, 3216 02:46:36,240 --> 02:46:40,400 we're basically talking about TDP-43 pathology 3217 02:46:40,400 --> 02:46:43,800 in common dementias in aging. 3218 02:46:43,800 --> 02:46:47,640 But the TDP-43 story really started 2006 3219 02:46:47,640 --> 02:46:52,000 with the seminal papers describing TDP-43 3220 02:46:52,000 --> 02:46:55,400 as the ubiquitin positive tau negative inclusion 3221 02:46:55,400 --> 02:46:58,600 of frontotemporal lobar degeneration, ALS. 3222 02:46:58,600 --> 02:47:04,080 So this was a pivotal discovery. It really changed the field 3223 02:47:04,080 --> 02:47:06,720 for frontotemporal lobar degeneration 3224 02:47:06,720 --> 02:47:08,800 and initially very short period of time 3225 02:47:08,800 --> 02:47:11,400 was thought to be specific. Next slide. 3226 02:47:15,120 --> 02:47:18,120 But as we looked at TDP-43 3227 02:47:18,120 --> 02:47:21,480 as this novel neurodegenerative proteinopathy, 3228 02:47:21,480 --> 02:47:26,160 it became clear very quickly that TDP-43 was not 3229 02:47:26,160 --> 02:47:29,480 only positive in frontotemporal lobar degeneration 3230 02:47:29,480 --> 02:47:31,680 but it's positive in other diseases 3231 02:47:31,680 --> 02:47:33,120 just like alpha synuclein 3232 02:47:33,120 --> 02:47:36,440 and tau, these misfolded proteins aren't -- 3233 02:47:36,440 --> 02:47:41,000 don't define one disease necessarily. 3234 02:47:41,000 --> 02:47:44,600 And, lo and behold, TDP-43 positivity 3235 02:47:44,600 --> 02:47:46,640 was quickly found to be evident 3236 02:47:46,640 --> 02:47:49,880 in Alzheimer's disease, pathology, 3237 02:47:49,880 --> 02:47:52,360 as well as hippocampal sclerosis pathology. 3238 02:47:52,360 --> 02:47:53,960 Next slide. 3239 02:47:56,000 --> 02:48:00,560 But even more astounding was that this TDP-43 pathology 3240 02:48:00,560 --> 02:48:03,360 was sometimes found in older people 3241 02:48:03,360 --> 02:48:05,720 completely lacking Alzheimer's disease, 3242 02:48:05,720 --> 02:48:08,280 or hippocampal sclerosis. 3243 02:48:08,280 --> 02:48:10,800 And as you'll see in a following slide, 3244 02:48:10,800 --> 02:48:14,000 that is why we came up with a new name for this 3245 02:48:14,000 --> 02:48:19,760 because, as of 2018, there was no name for this. 3246 02:48:19,760 --> 02:48:23,200 And if you look at the pie chart at the bottom of the slide, 3247 02:48:23,200 --> 02:48:26,080 this is a study that we did looking at people 3248 02:48:26,080 --> 02:48:29,720 who are called Alzheimer's disease in the community. 3249 02:48:29,720 --> 02:48:33,120 No biomarkers; they have an amnestic dementia. 3250 02:48:33,120 --> 02:48:35,400 And the red is showing people 3251 02:48:35,400 --> 02:48:37,680 with Alzheimer's disease pathology. 3252 02:48:37,680 --> 02:48:39,720 The purple is showing those people 3253 02:48:39,720 --> 02:48:42,920 with Alzheimer's disease pathology and TDP. 3254 02:48:42,920 --> 02:48:45,080 So the vast majority of these Alzheimer's, 3255 02:48:45,080 --> 02:48:48,320 these cases that we see in the community have TDP. 3256 02:48:48,320 --> 02:48:51,400 The blue slice is showing people 3257 02:48:51,400 --> 02:48:55,760 who did not have amyloid and tau but have LATE. 3258 02:48:55,760 --> 02:48:57,920 So they have a different diagnosis. 3259 02:48:57,920 --> 02:49:01,760 The white would be vascular dementia, Lewy body dementia. 3260 02:49:01,760 --> 02:49:05,000 So clearly a big part of this pie 3261 02:49:05,000 --> 02:49:09,320 is being completely disregarded by the community. 3262 02:49:09,320 --> 02:49:10,720 And this was very concerning. 3263 02:49:10,720 --> 02:49:12,880 There was very little research being done. 3264 02:49:12,880 --> 02:49:14,800 But at the same time, it was noted that 3265 02:49:14,800 --> 02:49:18,840 in biomarker studies that -- 3266 02:49:18,840 --> 02:49:23,760 that in biomarker studies that, you know, a good third of people 3267 02:49:23,760 --> 02:49:27,040 who are thought to have Alzheimer's disease don't. 3268 02:49:27,040 --> 02:49:29,000 But most of the research on TDP, 3269 02:49:29,000 --> 02:49:30,440 even though we saw this pathologically, 3270 02:49:30,440 --> 02:49:33,600 was really being done in the FTLD community. 3271 02:49:33,600 --> 02:49:39,480 Next slide. So to increase awareness 3272 02:49:39,480 --> 02:49:43,440 and really increase research in this TDP-43 pathology 3273 02:49:43,440 --> 02:49:45,040 and aging and Alzheimer's disease, 3274 02:49:45,040 --> 02:49:50,600 we convened a panel of 22 experts across 22 centers 3275 02:49:50,600 --> 02:49:52,280 and really discuss how are we going 3276 02:49:52,280 --> 02:49:56,280 to make this a research of focus. 3277 02:49:56,280 --> 02:49:59,320 And it's -- and a much needed focus. 3278 02:49:59,320 --> 02:50:02,680 And as Dr. Wolk will be showing you, 3279 02:50:02,680 --> 02:50:07,800 that, as an isolated pathology, it mimics Alzheimer's disease. 3280 02:50:07,800 --> 02:50:11,880 But even more commonly, when it's in conjunction 3281 02:50:11,880 --> 02:50:14,000 with Alzheimer's disease neuropathologic changes 3282 02:50:14,000 --> 02:50:15,480 of mixed pathology, 3283 02:50:15,480 --> 02:50:18,040 it accelerates decline and worsens memory. 3284 02:50:18,040 --> 02:50:21,280 It makes the person much worse. 3285 02:50:21,280 --> 02:50:25,800 So we clearly know that this needed to be studied, 3286 02:50:25,800 --> 02:50:28,400 and we needed to kind of upset the field to get it -- 3287 02:50:28,400 --> 02:50:30,600 to get it going. 3288 02:50:30,600 --> 02:50:33,680 And that is where we came up with the term limbic predominant 3289 02:50:33,680 --> 02:50:36,800 age-related TDP-43 encephalopathy, 3290 02:50:36,800 --> 02:50:40,080 which is also LATE, the pathology is called LATE NC 3291 02:50:40,080 --> 02:50:44,160 so LATE neuropathologic changes. A couple things to mention. 3292 02:50:44,160 --> 02:50:47,880 There is no frontotemporal lobar degeneration in these cases, 3293 02:50:47,880 --> 02:50:51,520 and there's not a frontal temporal dementia syndrome. 3294 02:50:51,520 --> 02:50:54,360 Instead, there's a prominent amnesia of people 3295 02:50:54,360 --> 02:50:56,560 with this pathology. Next slide. 3296 02:51:00,320 --> 02:51:03,800 So our 2022 LATE recommendations 3297 02:51:03,800 --> 02:51:07,160 continues this dire need for biomarkers. 3298 02:51:07,160 --> 02:51:11,520 We really need to be able to delineate 3299 02:51:11,520 --> 02:51:15,800 when somebody who does not have Alzheimer's disease has LATE, 3300 02:51:15,800 --> 02:51:17,800 and we need to know when someone with Alzheimer's disease 3301 02:51:17,800 --> 02:51:19,680 has LATE in addition to Alzheimer's disease 3302 02:51:19,680 --> 02:51:22,600 because maybe they won't respond to the amyloid therapy as well. 3303 02:51:22,600 --> 02:51:26,040 We need experimental models to start looking at this age 3304 02:51:26,040 --> 02:51:29,640 related TDP-43 update. 3305 02:51:29,640 --> 02:51:32,400 So biomarkers, experimental models, 3306 02:51:32,400 --> 02:51:36,040 still really important. But, in addition -- 3307 02:51:36,040 --> 02:51:38,960 and I'll show you in the next few slides -- 3308 02:51:38,960 --> 02:51:40,880 these boundaries that you've been hearing 3309 02:51:40,880 --> 02:51:42,800 about all of yesterday and today, 3310 02:51:42,800 --> 02:51:46,880 we really think need to be explored with LATE 3311 02:51:46,880 --> 02:51:49,200 and frontotemporal lobar degeneration, 3312 02:51:49,200 --> 02:51:54,120 as well as LATE with Alzheimer's disease and Lewy Body disease. 3313 02:51:54,120 --> 02:51:56,000 And I'll show you a little bit more about that 3314 02:51:56,000 --> 02:51:57,680 in just a minute. 3315 02:51:57,680 --> 02:52:00,360 But in addition to those boundaries, 3316 02:52:00,360 --> 02:52:04,680 we also see the need to look at the intersection of LATE 3317 02:52:04,680 --> 02:52:06,160 with hippocampal sclerosis, 3318 02:52:06,160 --> 02:52:09,520 which is a very important pathology in aging. 3319 02:52:09,520 --> 02:52:13,320 And especially as our population ages, 3320 02:52:13,320 --> 02:52:15,520 you're going to see that those numbers continue 3321 02:52:15,520 --> 02:52:17,520 to go up of hippocampal sclerosis, 3322 02:52:17,520 --> 02:52:21,760 the vast majority of which have TDP-43 pathology, 3323 02:52:21,760 --> 02:52:24,400 as well as an intersection with vascular disease 3324 02:52:24,400 --> 02:52:26,200 and aging senescence. 3325 02:52:26,200 --> 02:52:28,560 And I'll show you a little bit more about that too. 3326 02:52:28,560 --> 02:52:34,320 Next slide. So here is Recommendation 1, 3327 02:52:34,320 --> 02:52:40,120 define LATE pathologic clinical genetic molecular classification 3328 02:52:40,120 --> 02:52:45,440 and diagnostic boundaries across FTLD TDP, AD, 3329 02:52:45,440 --> 02:52:48,000 and other dementia-related pathologies 3330 02:52:48,000 --> 02:52:52,480 and their syndromes to enhance diagnosis, research, 3331 02:52:52,480 --> 02:52:57,600 and awareness. Next slide. 3332 02:52:57,600 --> 02:53:00,720 So here I'm just going to show you why this is so complex. 3333 02:53:00,720 --> 02:53:02,760 So here's -- in the white circle 3334 02:53:02,760 --> 02:53:06,200 is Alzheimer's disease neuropathologic changes occurs, 3335 02:53:06,200 --> 02:53:10,360 you know, in a large segment of the population, as we know. 3336 02:53:10,360 --> 02:53:12,200 And then, in red, you have people 3337 02:53:12,200 --> 02:53:14,240 with Alzheimer's disease neuropathologic changes 3338 02:53:14,240 --> 02:53:19,400 who also have TDP, so they have LATE neuropathologic changes. 3339 02:53:19,400 --> 02:53:22,000 So there's a lot of overlap there. 3340 02:53:22,000 --> 02:53:24,000 And you can see that there's a group 3341 02:53:24,000 --> 02:53:25,720 that does not have Alzheimer's disease 3342 02:53:25,720 --> 02:53:29,280 that may have a dementia just related to LATE. 3343 02:53:29,280 --> 02:53:31,800 But, in addition, I put in a purple circle 3344 02:53:31,800 --> 02:53:34,320 because that's hippocampal sclerosis. 3345 02:53:34,320 --> 02:53:38,000 And hippocampal sclerosis intersects with all of these. 3346 02:53:38,000 --> 02:53:42,520 The majority of them have TDP-43 pathology. 3347 02:53:42,520 --> 02:53:45,560 Some of them have Alzheimer's disease in addition. 3348 02:53:45,560 --> 02:53:49,000 In fact, the majority of them also have Alzheimer's disease. 3349 02:53:49,000 --> 02:53:50,680 Next; next, please. 3350 02:53:53,160 --> 02:53:55,440 And this is frontotemporal lobar degeneration. 3351 02:53:55,440 --> 02:53:57,040 And I made the circle small 3352 02:53:57,040 --> 02:53:59,320 because Alzheimer's disease is so much more common, 3353 02:53:59,320 --> 02:54:03,080 the frontotemporal lobar degeneration with TDP. 3354 02:54:03,080 --> 02:54:06,720 Next slide or next, yes. 3355 02:54:06,720 --> 02:54:08,600 But frontotemporal lobar degeneration 3356 02:54:08,600 --> 02:54:10,680 also has hippocampal sclerosis. 3357 02:54:10,680 --> 02:54:13,200 So there's something really going on with this -- 3358 02:54:13,200 --> 02:54:14,640 these proteinopathies, 3359 02:54:14,640 --> 02:54:20,000 especially TDP-43 and hippocampal sclerosis. Next. 3360 02:54:20,000 --> 02:54:21,640 And then there's Lewy body disease. 3361 02:54:21,640 --> 02:54:23,680 So we know already from the research that's been done 3362 02:54:23,680 --> 02:54:26,600 just over the past few years that Lewy bodies 3363 02:54:26,600 --> 02:54:30,400 are independently related to TDP-43 pathology, 3364 02:54:30,400 --> 02:54:32,480 even separate from Alzheimer's disease. 3365 02:54:32,480 --> 02:54:35,600 So, again, we're seeing this mixture of these different 3366 02:54:35,600 --> 02:54:39,200 proteinopathies being tremendously important. 3367 02:54:39,200 --> 02:54:40,760 And these intersections 3368 02:54:40,760 --> 02:54:42,800 aren't well-recognized clinically, pathologically. 3369 02:54:42,800 --> 02:54:44,840 They're not studied as well as they should be studied, 3370 02:54:44,840 --> 02:54:46,800 and this has been brought up multiple times 3371 02:54:46,800 --> 02:54:49,840 by multiple people. And this intersection 3372 02:54:49,840 --> 02:54:51,560 with frontotemporal lobar degeneration 3373 02:54:51,560 --> 02:54:53,280 is also very important, 3374 02:54:53,280 --> 02:54:55,880 and I'll show you a couple of reasons. 3375 02:54:55,880 --> 02:55:02,080 Next slide. So it quickly became clear -- 3376 02:55:02,080 --> 02:55:04,560 and this is just a snapshot of some papers -- 3377 02:55:04,560 --> 02:55:07,360 of the clinical and pathologic overlaps 3378 02:55:07,360 --> 02:55:13,600 or, you know, difficulty in classifying someone's cases 3379 02:55:13,600 --> 02:55:16,680 with TDP-43 and Alzheimer's disease 3380 02:55:16,680 --> 02:55:19,240 or with frontotemporal lobar degeneration 3381 02:55:19,240 --> 02:55:22,360 and limbic predominant TDP-43 deposition. 3382 02:55:22,360 --> 02:55:26,280 So, clearly, even though we'd like to make these all separate, 3383 02:55:26,280 --> 02:55:28,200 the frontal temporal lobar degeneration 3384 02:55:28,200 --> 02:55:31,840 and LATE, there's cases that intersect. 3385 02:55:31,840 --> 02:55:35,520 And we don't really understand the intersection 3386 02:55:35,520 --> 02:55:37,600 of these different proteinopathies again, 3387 02:55:37,600 --> 02:55:39,920 and a lot more work needs to be done. 3388 02:55:39,920 --> 02:55:43,400 Next slide. 3389 02:55:43,400 --> 02:55:45,800 But I don't think the clinical and pathology 3390 02:55:45,800 --> 02:55:47,600 is going to get us everywhere. 3391 02:55:47,600 --> 02:55:50,000 And we need the genetic, molecular, 3392 02:55:50,000 --> 02:55:52,800 and structural boundaries to really understand. 3393 02:55:52,800 --> 02:55:54,280 And you've heard a lot about that, too, 3394 02:55:54,280 --> 02:55:55,680 about the different strains 3395 02:55:55,680 --> 02:55:57,960 and different configurations and morphologies. 3396 02:55:57,960 --> 02:56:00,680 But look here on this first study 3397 02:56:00,680 --> 02:56:05,560 where APOE is not only a risk factor for Alzheimer's disease 3398 02:56:05,560 --> 02:56:08,200 but it also increases risk for Lewy body disease, 3399 02:56:08,200 --> 02:56:10,640 as well as TDP-43. 3400 02:56:10,640 --> 02:56:12,160 TMEM106B, 3401 02:56:12,160 --> 02:56:15,320 a risk factor for frontotemporal lobar degeneration, 3402 02:56:15,320 --> 02:56:19,000 increases TDP-43 pathology in aging. 3403 02:56:19,000 --> 02:56:24,760 So, clearly, these mechanisms overlap across disease states. 3404 02:56:24,760 --> 02:56:27,680 And then, as you've heard through this conference, 3405 02:56:27,680 --> 02:56:31,480 you know, we're learning more still about what these different 3406 02:56:31,480 --> 02:56:34,440 aggregates look like in different disease states. 3407 02:56:34,440 --> 02:56:36,200 Next slide. 3408 02:56:36,200 --> 02:56:37,800 -Two minutes remaining. 3409 02:56:40,200 --> 02:56:43,000 -So the last thing I want to talk about is that the -- 3410 02:56:43,000 --> 02:56:45,760 our fourth and final recommendation, 3411 02:56:45,760 --> 02:56:47,320 which is really to pay attention 3412 02:56:47,320 --> 02:56:50,000 or to study this intersection of hippocampal sclerosis 3413 02:56:50,000 --> 02:56:52,840 in the role of age and vascular disease. 3414 02:56:52,840 --> 02:56:55,240 So we've known about hippocampal sclerosis 3415 02:56:55,240 --> 02:56:58,000 in the pathology world for a long time. 3416 02:56:58,000 --> 02:57:01,280 We know that it can mimic an Alzheimer's type dementia. 3417 02:57:01,280 --> 02:57:05,000 We know it's very common in the oldest old. 3418 02:57:05,000 --> 02:57:08,000 And there's a lot of interest in hippocampal sclerosis 3419 02:57:08,000 --> 02:57:09,640 in the pathology world, 3420 02:57:09,640 --> 02:57:11,600 but it's not really noted clinically very well or studied 3421 02:57:11,600 --> 02:57:15,800 from a nonclinical or pathologic standpoint. 3422 02:57:15,800 --> 02:57:18,000 Almost all cases of hippocampal sclerosis 3423 02:57:18,000 --> 02:57:21,000 with aging have TDP-43 pathology, 3424 02:57:21,000 --> 02:57:23,000 but it's not a specific pathology. 3425 02:57:23,000 --> 02:57:25,000 All hippocampal sclerosis is, 3426 02:57:25,000 --> 02:57:28,760 is severe degeneration of the hippocampus in aging. 3427 02:57:28,760 --> 02:57:30,400 And you can also see it interestingly 3428 02:57:30,400 --> 02:57:35,120 with apoptsic ischemic injury. Next slide. 3429 02:57:35,120 --> 02:57:39,000 I should also mention that there are no pathologic standards 3430 02:57:39,000 --> 02:57:40,560 for hippocampal sclerosis. 3431 02:57:40,560 --> 02:57:42,360 So we have no consensus criteria. 3432 02:57:42,360 --> 02:57:45,360 We take one section of hippocampus, a huge structure, 3433 02:57:45,360 --> 02:57:47,640 and do a six micron section to look for it. 3434 02:57:47,640 --> 02:57:50,160 But we know from that finished study on the other slot -- 3435 02:57:50,160 --> 02:57:52,200 slide that it's patchy, 3436 02:57:52,200 --> 02:57:56,080 and we might not always be seeing the pathology. 3437 02:57:56,080 --> 02:57:58,200 But we also, in addition to that, 3438 02:57:58,200 --> 02:58:01,480 know that both TDP-43 and hippocampal sclerosis 3439 02:58:01,480 --> 02:58:03,200 are age-related pathologies. 3440 02:58:03,200 --> 02:58:09,240 And this is a study by Leah Greenberg and Salvatore Spina, 3441 02:58:09,240 --> 02:58:12,120 showing that cerebral amyloid angiopathy in Lewy body disease 3442 02:58:12,120 --> 02:58:15,720 are actually very common in early onset Alzheimer's disease, 3443 02:58:15,720 --> 02:58:18,880 whereas TDP-43 and hippocampus sclerosis are rarely present. 3444 02:58:18,880 --> 02:58:21,200 They're really an age-related phenomenon. 3445 02:58:21,200 --> 02:58:25,040 And we have an aging society, so we really need to understand 3446 02:58:25,040 --> 02:58:29,600 in studies that use aging within their models what is happening. 3447 02:58:29,600 --> 02:58:34,240 And then, finally, there's inflammation 3448 02:58:34,240 --> 02:58:37,000 or there's data suggesting for multiple groups 3449 02:58:37,000 --> 02:58:40,640 now that vascular disease also intersects. 3450 02:58:40,640 --> 02:58:42,400 So here we have a couple different groups 3451 02:58:42,400 --> 02:58:44,040 showing that arterial sclerosis 3452 02:58:44,040 --> 02:58:45,800 is related to hippocampal sclerosis. 3453 02:58:45,800 --> 02:58:49,520 We in our group found that arteriosclerosis 3454 02:58:49,520 --> 02:58:53,400 was related to TDP-43 pathology. 3455 02:58:53,400 --> 02:58:59,120 So what that exactly means or why that would be interacting 3456 02:58:59,120 --> 02:59:01,800 is completely at this point unknown. 3457 02:59:01,800 --> 02:59:03,800 Next slide. 3458 02:59:03,800 --> 02:59:05,040 -Time. 3459 02:59:05,040 --> 02:59:08,000 -Next slide. So this is my last slide. 3460 02:59:08,000 --> 02:59:09,640 So, this is recommendation number 4. 3461 02:59:09,640 --> 02:59:12,880 To study this intersection with hippocampal sclerosis 3462 02:59:12,880 --> 02:59:16,160 and LATE NC within and across all disciplines again, 3463 02:59:16,160 --> 02:59:17,560 not just clinical and pathologic 3464 02:59:17,560 --> 02:59:20,280 but diagnostic, genetic, molecular, 3465 02:59:20,280 --> 02:59:23,800 and to consider the roles of vasculopathy and senescence 3466 02:59:23,800 --> 02:59:26,720 and other potential contributing factors. 3467 02:59:26,720 --> 02:59:28,280 So thank you for your attention. 3468 02:59:28,280 --> 02:59:32,480 And I'm going to hand the reins over to Dr. Wolk. 3469 02:59:32,480 --> 02:59:37,040 -Thanks so much, Julie. Next slide. 3470 02:59:37,040 --> 02:59:41,880 So, I'm going to focus, as Julie said, on recommendation 2. 3471 02:59:41,880 --> 02:59:45,760 We'll talk about our current understanding and knowledge gaps 3472 02:59:45,760 --> 02:59:48,640 in the clinical manifestations of LATE. 3473 02:59:48,640 --> 02:59:52,000 And then I think we'll discuss where we are now 3474 02:59:52,000 --> 02:59:53,800 with clinical detection of LATE 3475 02:59:53,800 --> 02:59:57,000 and kind of where we need to go moving forward. 3476 02:59:57,000 --> 03:00:02,160 Next slide. So this is recommendation 2. 3477 03:00:02,160 --> 03:00:07,160 It is -- sort of builds off of the prior summit. 3478 03:00:07,160 --> 03:00:10,280 It developed -- it's to develop biomarkers, classifiers, 3479 03:00:10,280 --> 03:00:12,800 and risk profiles to establish 3480 03:00:12,800 --> 03:00:16,840 an in vivo diagnostic criteria for LATE 3481 03:00:16,840 --> 03:00:20,360 in people in the preclinical phase of the disease, 3482 03:00:20,360 --> 03:00:23,200 as well as those with an amnestic 3483 03:00:23,200 --> 03:00:25,560 LATE life dementia syndrome. 3484 03:00:25,560 --> 03:00:27,560 I won't go through each of these bullet points 3485 03:00:27,560 --> 03:00:30,360 because I think they get set up in the later slides. 3486 03:00:30,360 --> 03:00:32,680 But I will point out the last bullet point, 3487 03:00:32,680 --> 03:00:36,000 which is that, ultimately, we really do need to develop 3488 03:00:36,000 --> 03:00:40,600 bio fluid and neuro imaging and/or neuroimaging biomarkers 3489 03:00:40,600 --> 03:00:42,800 of the molecular pathology of LATE 3490 03:00:42,800 --> 03:00:45,480 and, in particular, TDP-43. 3491 03:00:45,480 --> 03:00:48,440 However, until we get to that goal, 3492 03:00:48,440 --> 03:00:52,480 we felt that we really need to develop 3493 03:00:52,480 --> 03:00:55,800 probabilistic classifiers that are validated for us 3494 03:00:55,800 --> 03:00:59,480 to be able to do in vivo studies in this population. 3495 03:00:59,480 --> 03:01:02,000 Next slide. 3496 03:01:02,000 --> 03:01:04,320 So just wanted to provide a little bit of context 3497 03:01:04,320 --> 03:01:07,480 and in part because this demonstrates 3498 03:01:07,480 --> 03:01:11,600 that we see these cases in our clinics already. 3499 03:01:11,600 --> 03:01:14,640 This is a 78-year-old woman who had arthritis, 3500 03:01:14,640 --> 03:01:18,560 prior hysterectomy for uterine cancer; and depression. 3501 03:01:18,560 --> 03:01:20,680 She had several years of memory loss. 3502 03:01:20,680 --> 03:01:23,120 She would forget where she parked her car, 3503 03:01:23,120 --> 03:01:25,480 and she was misplacing things. 3504 03:01:25,480 --> 03:01:27,440 She previously was great with the computer 3505 03:01:27,440 --> 03:01:29,440 and had increasing difficulty, 3506 03:01:29,440 --> 03:01:32,200 and her family felt she seemed a little more stressed out 3507 03:01:32,200 --> 03:01:34,000 and struggled more with decisions. 3508 03:01:34,000 --> 03:01:36,880 Next slide. 3509 03:01:36,880 --> 03:01:39,680 These are her initial standard psychometric testing. 3510 03:01:39,680 --> 03:01:42,200 And the important thing to point out here 3511 03:01:42,200 --> 03:01:45,760 is in purple where she's impaired are all tests 3512 03:01:45,760 --> 03:01:48,120 that have to do with verbal or visual memory. 3513 03:01:48,120 --> 03:01:51,520 Other cognitive demands were essentially intact. 3514 03:01:51,520 --> 03:01:55,880 Next slide. So this was her initial MRI, 3515 03:01:55,880 --> 03:01:59,560 and I hope you can appreciate that, 3516 03:01:59,560 --> 03:02:02,400 in the right anterior hippocampus, 3517 03:02:02,400 --> 03:02:04,000 there was some degree of atrophy. 3518 03:02:04,000 --> 03:02:06,600 But there wasn't a lot of cortical atrophy otherwise 3519 03:02:06,600 --> 03:02:09,000 and maybe a little bit of vascular disease, 3520 03:02:09,000 --> 03:02:13,080 small vessel disease. Next slide. 3521 03:02:13,080 --> 03:02:15,200 So she had a very slow course. 3522 03:02:15,200 --> 03:02:18,000 We followed her for over nine years. 3523 03:02:18,000 --> 03:02:20,120 On the left, you can see her psychometric testing, 3524 03:02:20,120 --> 03:02:21,800 which kind of barely changed over time 3525 03:02:21,800 --> 03:02:23,400 but did get a little bit worse. 3526 03:02:23,400 --> 03:02:28,800 She had poor memory, but that remained relatively stable. 3527 03:02:28,800 --> 03:02:33,200 They noticed some decreases in her attention and motivation. 3528 03:02:33,200 --> 03:02:35,080 She also had a little bit of disinhibition. 3529 03:02:35,080 --> 03:02:37,000 She would say negative things about people 3530 03:02:37,000 --> 03:02:41,280 while they were in the room, which embarrassed her daughter. 3531 03:02:41,280 --> 03:02:43,520 The important point is, throughout her entire course, 3532 03:02:43,520 --> 03:02:47,000 she had a diagnosis of Alzheimer's disease. 3533 03:02:47,000 --> 03:02:51,160 Next slide. This is her CAT scan 3534 03:02:51,160 --> 03:02:54,120 that was done just a few months before she passed away. 3535 03:02:54,120 --> 03:02:56,240 And now I think you can really appreciate 3536 03:02:56,240 --> 03:02:57,640 both anterior hippocampal 3537 03:02:57,640 --> 03:03:01,120 and anterior temporal atrophy bilaterally, 3538 03:03:01,120 --> 03:03:03,920 a little bit more on the right than the left, 3539 03:03:03,920 --> 03:03:06,920 and some cortical atrophy perhaps a little bit frontal 3540 03:03:06,920 --> 03:03:10,600 but, otherwise, not too much. Next slide. 3541 03:03:10,600 --> 03:03:12,800 So she went on to autopsy 3542 03:03:12,800 --> 03:03:16,600 and was found as a primary pathologic diagnosis 3543 03:03:16,600 --> 03:03:19,000 to have a LATE neuropathic change 3544 03:03:19,000 --> 03:03:21,720 without any evidence of Alzheimer's disease. 3545 03:03:21,720 --> 03:03:24,440 So, again, this would be an example of a case 3546 03:03:24,440 --> 03:03:28,000 that we misdiagnosed as Alzheimer's disease. 3547 03:03:28,000 --> 03:03:30,320 Next slide. 3548 03:03:30,320 --> 03:03:32,040 So I think since the last summit 3549 03:03:32,040 --> 03:03:34,200 we actually have made a fair bit of progress 3550 03:03:34,200 --> 03:03:38,600 in defining the clinical features of LATE. 3551 03:03:38,600 --> 03:03:41,160 For example, on the left, you can see and consistent 3552 03:03:41,160 --> 03:03:43,560 with this case that LATE neuropathic changes 3553 03:03:43,560 --> 03:03:46,560 associated with a relatively slow course of decline 3554 03:03:46,560 --> 03:03:50,000 compared to Alzheimer's disease. 3555 03:03:50,000 --> 03:03:52,600 Episodic memory tends to be 3556 03:03:52,600 --> 03:03:54,720 the most prominently affected domain, 3557 03:03:54,720 --> 03:03:57,520 and that can be very significantly affected. 3558 03:03:57,520 --> 03:03:58,920 There's still some question about whether 3559 03:03:58,920 --> 03:04:01,400 other domains are affected 3560 03:04:01,400 --> 03:04:04,760 and to what extent, such as semantic memory. 3561 03:04:04,760 --> 03:04:07,920 While these cases certainly do not have 3562 03:04:07,920 --> 03:04:10,360 the behavioral manifestations 3563 03:04:10,360 --> 03:04:13,000 of full blown FTD spectrum disorders, 3564 03:04:13,000 --> 03:04:14,480 there's also some question whether they have 3565 03:04:14,480 --> 03:04:17,960 some behavioral associations such as this case. 3566 03:04:17,960 --> 03:04:20,160 The important point is, when you look at population 3567 03:04:20,160 --> 03:04:22,400 and community based autopsy studies, 3568 03:04:22,400 --> 03:04:25,120 these individuals represent about 1 in 10 individuals. 3569 03:04:25,120 --> 03:04:28,000 This is a common condition. Next slide. 3570 03:04:30,080 --> 03:04:32,920 In terms of thinking about what other kinds 3571 03:04:32,920 --> 03:04:35,000 of cognitive and behavioral symptoms 3572 03:04:35,000 --> 03:04:37,600 may be present in these individuals, 3573 03:04:37,600 --> 03:04:41,520 I think it's useful to think about where TDP-43 3574 03:04:41,520 --> 03:04:44,240 spreads in the brain in the context of LATE. 3575 03:04:44,240 --> 03:04:45,640 And I should note there are three different 3576 03:04:45,640 --> 03:04:47,800 staging systems out there, 3577 03:04:47,800 --> 03:04:50,280 all with different levels of granularity. 3578 03:04:50,280 --> 03:04:53,640 But the bottom line is they show regions 3579 03:04:53,640 --> 03:04:56,200 that are affected such as anterior temporal cortex, 3580 03:04:56,200 --> 03:05:00,240 orbital frontal cortex, insula, middle frontal gyrus, 3581 03:05:00,240 --> 03:05:03,000 which suggests that there may be additional impairments 3582 03:05:03,000 --> 03:05:06,640 and semantic memory behavior and perhaps, 3583 03:05:06,640 --> 03:05:09,400 to some extent, executive functioning. 3584 03:05:09,400 --> 03:05:14,200 Next slide. It turns out, 3585 03:05:14,200 --> 03:05:18,520 when LATE is associated with hippocampal sclerosis, 3586 03:05:18,520 --> 03:05:21,520 we actually do see more significant decline 3587 03:05:21,520 --> 03:05:25,880 not only in memory but we do see involvement in semantic memory 3588 03:05:25,880 --> 03:05:30,360 and perhaps to some extent perceptual speed. 3589 03:05:30,360 --> 03:05:33,920 Next slide. 3590 03:05:33,920 --> 03:05:37,920 So -- and this touches a little bit on recommendation 4, 3591 03:05:37,920 --> 03:05:43,240 but we really need to understand the clinical phenotype 3592 03:05:43,240 --> 03:05:47,040 that differentiates LATE with hippocampal sclerosis 3593 03:05:47,040 --> 03:05:49,960 versus LATE without hippocampal sclerosis. 3594 03:05:49,960 --> 03:05:51,520 But as Julie mentioned, 3595 03:05:51,520 --> 03:05:57,440 we also really need to study the drivers of LATE. 3596 03:05:57,440 --> 03:06:02,160 We do know some things about how hippocampal sclerosis 3597 03:06:02,160 --> 03:06:04,120 presents in the setting of LATE. 3598 03:06:04,120 --> 03:06:07,400 These individuals, as I mentioned already do seem 3599 03:06:07,400 --> 03:06:10,040 to show more severe cognitive impairment, 3600 03:06:10,040 --> 03:06:11,760 particularly memory, 3601 03:06:11,760 --> 03:06:16,560 but they also tend to have a higher or later stage of LATE 3602 03:06:16,560 --> 03:06:19,520 in terms of the spread of TDP-43. 3603 03:06:19,520 --> 03:06:22,040 So it's not surprising that these individuals 3604 03:06:22,040 --> 03:06:24,120 have other domains of cognitive impairment 3605 03:06:24,120 --> 03:06:26,800 like semantic memory affected. 3606 03:06:26,800 --> 03:06:31,800 As was also mentioned before, these individuals seem to have 3607 03:06:31,800 --> 03:06:34,080 some relationship with vascular disease. 3608 03:06:34,080 --> 03:06:36,760 They have a higher rate of atherosclerosis 3609 03:06:36,760 --> 03:06:38,600 that's been described. 3610 03:06:38,600 --> 03:06:41,000 Interestingly, the genetics of LATE 3611 03:06:41,000 --> 03:06:44,280 alone versus LATE with hippocampal sclerosis 3612 03:06:44,280 --> 03:06:46,800 may differ as shown on the right. 3613 03:06:46,800 --> 03:06:49,760 And, importantly, as we are starting to develop 3614 03:06:49,760 --> 03:06:52,200 these sort of genetic risks of LATE, 3615 03:06:52,200 --> 03:06:54,600 these are features that can be included 3616 03:06:54,600 --> 03:06:56,120 in classification models 3617 03:06:56,120 --> 03:07:00,960 as we move forward to define the disease in vivo. 3618 03:07:00,960 --> 03:07:04,320 Next slide. 3619 03:07:04,320 --> 03:07:08,160 So we've been talking about LATE neuropathic change alone, 3620 03:07:08,160 --> 03:07:11,120 but I think one of the really important areas 3621 03:07:11,120 --> 03:07:15,240 is how it interacts with other neurodegenerative conditions, 3622 03:07:15,240 --> 03:07:18,480 particularly Alzheimer's disease. 3623 03:07:18,480 --> 03:07:23,720 So on the left is relatively new data from 13 community 3624 03:07:23,720 --> 03:07:26,400 and population based autopsy cohorts, 3625 03:07:26,400 --> 03:07:29,360 which suggests that up to half of individuals 3626 03:07:29,360 --> 03:07:31,800 who have late stage Alzheimer's disease, 3627 03:07:31,800 --> 03:07:36,280 neuropathic change also have LATE neuropathic change. 3628 03:07:36,280 --> 03:07:38,520 And, importantly, 3629 03:07:38,520 --> 03:07:41,400 in the combination of Alzheimer's disease and LATE 3630 03:07:41,400 --> 03:07:45,520 seems to be associated with a much accelerated decline 3631 03:07:45,520 --> 03:07:49,600 over time that we see relative to Alzheimer's disease. 3632 03:07:49,600 --> 03:07:52,040 So it's really the fastest progressing form 3633 03:07:52,040 --> 03:07:54,160 of Alzheimer's disease in some ways. 3634 03:07:54,160 --> 03:07:57,600 And, actually, if you look at different stages of Alzheimer's 3635 03:07:57,600 --> 03:07:59,960 based on Braak stage, at any of those stages, 3636 03:07:59,960 --> 03:08:05,120 the presence of LATE is associated with poor cognition. 3637 03:08:05,120 --> 03:08:08,040 Next slide. 3638 03:08:08,040 --> 03:08:11,200 So detection of LATE in clinical populations, 3639 03:08:11,200 --> 03:08:13,520 I think, is critically important. 3640 03:08:13,520 --> 03:08:15,520 It's a common source of cognitive impairment 3641 03:08:15,520 --> 03:08:16,960 in older adults. 3642 03:08:16,960 --> 03:08:20,280 And in clinical diagnosis of Alzheimer's disease 3643 03:08:20,280 --> 03:08:24,000 probably makes up 20% of the attributable risk. 3644 03:08:24,000 --> 03:08:25,520 It has important prognostic 3645 03:08:25,520 --> 03:08:27,120 and potentially treatment implications 3646 03:08:27,120 --> 03:08:30,080 and amnestic cognitive impairment presentations. 3647 03:08:30,080 --> 03:08:33,240 A slower course is expected in someone 3648 03:08:33,240 --> 03:08:35,240 who has it in the absence of Alzheimer's, 3649 03:08:35,240 --> 03:08:38,520 but a much more rapid course is expected in patients 3650 03:08:38,520 --> 03:08:40,600 who do have Alzheimer's disease. 3651 03:08:40,600 --> 03:08:43,560 And, really, our ability to be able to detect it in vivo 3652 03:08:43,560 --> 03:08:46,400 is what's going to allow us to do broader studies of risk, 3653 03:08:46,400 --> 03:08:49,000 genetics, clinical and cognitive phenotype 3654 03:08:49,000 --> 03:08:52,200 and eventually intervention studies. 3655 03:08:52,200 --> 03:08:54,200 I think, though, critically important 3656 03:08:54,200 --> 03:08:56,480 to the Alzheimer's disease field 3657 03:08:56,480 --> 03:09:00,440 is that it's a major source of variability in progression 3658 03:09:00,440 --> 03:09:04,200 that can impact clinical trials and may also limit the efficacy 3659 03:09:04,200 --> 03:09:07,400 when specifically targeting AD pathophysiology. 3660 03:09:07,400 --> 03:09:11,080 And, currently, there are no molecularly specific markers 3661 03:09:11,080 --> 03:09:14,640 of TDP-43. Next slide. 3662 03:09:14,640 --> 03:09:17,200 So then how can we detect it now? 3663 03:09:17,200 --> 03:09:21,000 And, again, there have been some progress since the last summit. 3664 03:09:21,000 --> 03:09:24,440 For one thing, there are spatial patterns of neurodegeneration 3665 03:09:24,440 --> 03:09:28,600 based on atrophy or hypometabolism on PET, 3666 03:09:28,600 --> 03:09:31,040 which can be suggestive of LATE neuropathic change. 3667 03:09:31,040 --> 03:09:34,960 And they've been linked to post mortem data to various extents. 3668 03:09:34,960 --> 03:09:39,080 One also can inferentially determine the likelihood of LATE 3669 03:09:39,080 --> 03:09:41,240 based on Alzheimer's disease markers. 3670 03:09:41,240 --> 03:09:42,800 So Alzheimer's disease is defined 3671 03:09:42,800 --> 03:09:46,560 by the presence of amyloid and tau biomarkers. 3672 03:09:46,560 --> 03:09:51,800 And neurodegeneration is used to sort of stage individuals, 3673 03:09:51,800 --> 03:09:54,400 the so-called ATN framework. 3674 03:09:54,400 --> 03:09:56,520 Well, if an individual is amyloid negative 3675 03:09:56,520 --> 03:09:58,520 with an amnestic syndrome, 3676 03:09:58,520 --> 03:10:01,600 particularly if they have atrophy in a LATE like pattern, 3677 03:10:01,600 --> 03:10:04,160 they're much more likely to have LATE. 3678 03:10:04,160 --> 03:10:05,640 But we really want to be able to detect it 3679 03:10:05,640 --> 03:10:09,560 when individuals also have Alzheimer's disease. 3680 03:10:09,560 --> 03:10:10,960 And what we know is, 3681 03:10:10,960 --> 03:10:13,080 within that Alzheimer's disease continuum, 3682 03:10:13,080 --> 03:10:15,840 tau is tightly linked to neurodegeneration. 3683 03:10:15,840 --> 03:10:18,640 So if an individual has significant medial 3684 03:10:18,640 --> 03:10:20,240 temporal lobe atrophy 3685 03:10:20,240 --> 03:10:22,800 and a LATE like pattern in the absence of tau pathology, 3686 03:10:22,800 --> 03:10:27,880 that may suggest LATE. Or if they have tau pathology 3687 03:10:27,880 --> 03:10:30,360 but neurodegeneration exceeds what we expect, 3688 03:10:30,360 --> 03:10:33,360 that, too, might be a marker to use for LATE. 3689 03:10:33,360 --> 03:10:36,280 Next slide. 3690 03:10:36,280 --> 03:10:39,840 So, again, there have been -- there has been work showing 3691 03:10:39,840 --> 03:10:43,640 that there are spatial patterns to change that occur with LATE 3692 03:10:43,640 --> 03:10:46,320 that may differentiate it from Alzheimer's disease. 3693 03:10:46,320 --> 03:10:48,960 So, for example, on the left is post mortem work 3694 03:10:48,960 --> 03:10:53,400 showing amygdala patterns of atrophy or shape change. 3695 03:10:53,400 --> 03:10:55,200 And on the right is a study we did 3696 03:10:55,200 --> 03:10:57,400 where we looked at antemortem MRI 3697 03:10:57,400 --> 03:11:00,760 and found that Alzheimer's disease with TDP-43 3698 03:11:00,760 --> 03:11:03,600 tended to have more anterior medial temporal atrophy 3699 03:11:03,600 --> 03:11:05,400 than Alzheimer's disease without it. 3700 03:11:05,400 --> 03:11:07,520 And, actually, if you took a ratio of anterior 3701 03:11:07,520 --> 03:11:09,640 to posterior MTL, 3702 03:11:09,640 --> 03:11:12,360 there was fairly good discrimination 3703 03:11:12,360 --> 03:11:15,040 between these groups. Next slide. 3704 03:11:15,040 --> 03:11:16,640 -Two minutes remaining. 3705 03:11:19,040 --> 03:11:21,920 -We also have seen that there are cortical patterns 3706 03:11:21,920 --> 03:11:25,640 of atrophy in LATE. So, for example, on the left 3707 03:11:25,640 --> 03:11:28,800 is a post mortem study showing atrophy 3708 03:11:28,800 --> 03:11:32,000 in temporal polar regions and frontal regions. 3709 03:11:32,000 --> 03:11:34,920 And this has also been seen in vivo as well, 3710 03:11:34,920 --> 03:11:36,320 where in particular, again, 3711 03:11:36,320 --> 03:11:38,000 you see this gradient of greater anterior 3712 03:11:38,000 --> 03:11:41,520 than posterior temporal involvement. Next slide. 3713 03:11:44,920 --> 03:11:48,320 There also have been FDG PET signatures of LATE, 3714 03:11:48,320 --> 03:11:50,760 some really nice work done by the Mayo group, 3715 03:11:50,760 --> 03:11:52,320 which has found 3716 03:11:52,320 --> 03:11:54,760 particularly severe medial temporal hypometabolism 3717 03:11:54,760 --> 03:11:58,320 relative to inferior temporal hypometabolism. 3718 03:11:58,320 --> 03:12:01,360 And this discriminates between Alzheimer's disease and LATE. 3719 03:12:01,360 --> 03:12:02,800 And if, in more recent work, 3720 03:12:02,800 --> 03:12:04,840 if you add orbital frontal cortex, 3721 03:12:04,840 --> 03:12:06,880 that further increases discrimination. 3722 03:12:06,880 --> 03:12:09,200 Next slide. 3723 03:12:09,200 --> 03:12:13,160 But, again, we can establish the diagnosis 3724 03:12:13,160 --> 03:12:18,000 inferentially through AD biomarkers. 3725 03:12:18,000 --> 03:12:20,040 So this is a case of someone 3726 03:12:20,040 --> 03:12:22,440 who's 83 with an amnestic presentation 3727 03:12:22,440 --> 03:12:26,400 who has had positive amyloid marker but negative tau. 3728 03:12:26,400 --> 03:12:29,880 Next slide. However, they also had 3729 03:12:29,880 --> 03:12:31,840 very significant hippocampal atrophy -- 3730 03:12:31,840 --> 03:12:35,640 next slide -- as well as a little bit of athero. 3731 03:12:35,640 --> 03:12:38,400 So this is a case that had neurodegeneration 3732 03:12:38,400 --> 03:12:40,400 in the medial temporal lobe without tau. 3733 03:12:40,400 --> 03:12:43,400 And so we might expect a non AD driver of Alzheimer's disease. 3734 03:12:43,400 --> 03:12:45,520 Next slide. 3735 03:12:45,520 --> 03:12:48,000 And, indeed, this was a stage two LATE case. 3736 03:12:48,000 --> 03:12:51,840 Next slide. We've also been trying to look 3737 03:12:51,840 --> 03:12:54,640 at the relative amount of tau to atrophy. 3738 03:12:54,640 --> 03:12:56,880 And I've had -- found people who have more atrophy 3739 03:12:56,880 --> 03:12:59,360 than expected for a given level of tau. 3740 03:12:59,360 --> 03:13:04,400 And, in fact, some of those individuals have that increase 3741 03:13:04,400 --> 03:13:08,440 or mismatch of neurodegeneration in LATE-like regions. 3742 03:13:08,440 --> 03:13:10,640 And, actually, we can cluster these groups together 3743 03:13:10,640 --> 03:13:12,520 using machine learning based approaches. 3744 03:13:12,520 --> 03:13:14,200 Next slide. 3745 03:13:14,200 --> 03:13:15,800 -Time. 3746 03:13:15,800 --> 03:13:17,640 -And what we've found is that 3747 03:13:17,640 --> 03:13:19,880 there's a limbic vulnerable group 3748 03:13:19,880 --> 03:13:21,120 and a limbic resilient group. 3749 03:13:21,120 --> 03:13:22,960 But, importantly, the vulnerable group 3750 03:13:22,960 --> 03:13:27,560 tends to have high levels of TDP-43 in post mortem analyses 3751 03:13:27,560 --> 03:13:31,680 whereas the limbic has, if anything, low levels. 3752 03:13:31,680 --> 03:13:35,440 Next slide.

Next slide, please. 3904 03:21:51,480 --> 03:21:54,600 Transgenic animals that express wild-type or immune TDP 43 3905 03:21:54,600 --> 03:21:56,560 or developed hippocampal sclerosis. 3906 03:21:56,560 --> 03:21:58,160 Back one, please. 3907 03:22:01,240 --> 03:22:04,640 Back one slide, please. Thank you. 3908 03:22:04,640 --> 03:22:06,880 So, Wuhan colleagues did a conditional knockout 3909 03:22:06,880 --> 03:22:10,760 in the hippocampus. And, over the course of time, 3910 03:22:10,760 --> 03:22:15,160 at 12 months of age they show distinct degenerate -- 3911 03:22:15,160 --> 03:22:17,600 distinct severe hippocampal degeneration 3912 03:22:17,600 --> 03:22:21,320 over the course of time at 12 months of age. 3913 03:22:21,320 --> 03:22:22,920 Next slide, please. 3914 03:22:27,080 --> 03:22:29,480 This is unpublished work from our lab. 3915 03:22:29,480 --> 03:22:31,880 We looked at hippocampal degeneration 3916 03:22:31,880 --> 03:22:37,120 as seen in 24-month-old mice expressing nuclear localization 3917 03:22:37,120 --> 03:22:40,000 signal defective TDP at 43 months. 3918 03:22:40,000 --> 03:22:41,960 These are in -- these are six genotypes 3919 03:22:41,960 --> 03:22:45,000 that we looked at with wild-type APP-PS1, 3920 03:22:45,000 --> 03:22:47,760 a low expressing TDP mouse. 3921 03:22:47,760 --> 03:22:52,160 And it's TDP in the mouse expressing lower TDP 3922 03:22:52,160 --> 03:22:54,920 43 expression in an APP background. 3923 03:22:54,920 --> 03:22:57,360 They show no neuronal loss at 24 months of age. 3924 03:22:57,360 --> 03:22:59,800 And they show no change in hippocampal area. 3925 03:22:59,800 --> 03:23:01,400 However, when we derive expression 3926 03:23:01,400 --> 03:23:03,200 of TDP 43 in the cytoplasm -- 3927 03:23:03,200 --> 03:23:04,840 and this is end stage for these mice. 3928 03:23:04,840 --> 03:23:08,720 These mice only live 24 to 25 months of age, 3929 03:23:08,720 --> 03:23:10,440 the NLS mice in particular. 3930 03:23:10,440 --> 03:23:12,960 When we derive TDP 43 in the cytoplasm, 3931 03:23:12,960 --> 03:23:18,160 we get this severe degeneration of the hippocampus. 3932 03:23:18,160 --> 03:23:20,800 And we get a decrease in hippocampal volume. 3933 03:23:20,800 --> 03:23:22,400 And in the end in the APP background, 3934 03:23:22,400 --> 03:23:24,800 there's no additive effect with these. 3935 03:23:24,800 --> 03:23:26,160 And this will go into the next slide, 3936 03:23:26,160 --> 03:23:29,200 where I can talk about model limitations. 3937 03:23:29,200 --> 03:23:32,240 Next slide, please. 3938 03:23:32,240 --> 03:23:34,320 So, model limitations 3939 03:23:34,320 --> 03:23:35,760 I want to talk about the cAMP kinase model, 3940 03:23:35,760 --> 03:23:38,040 that I described for the one that we use. 3941 03:23:38,040 --> 03:23:39,960 Gowan and Associates from Jackson lab 3942 03:23:39,960 --> 03:23:41,600 is an excellent paper. 3943 03:23:41,600 --> 03:23:46,840 They mapped quite a few different transgenic lines 3944 03:23:46,840 --> 03:23:49,120 for their integration sites. 3945 03:23:49,120 --> 03:23:52,000 And it just so happens the cAMP kinase TTA model 3946 03:23:52,000 --> 03:23:56,120 that we use was mapped in five coding regions, the gene. 3947 03:23:56,120 --> 03:23:58,680 And there's, also, some abnormalities 3948 03:23:58,680 --> 03:24:01,920 with some motor deficits in these mice 3949 03:24:01,920 --> 03:24:06,560 as well that show some clasping later on. 3950 03:24:06,560 --> 03:24:09,480 So, this brings us to rigor and reproducibility. 3951 03:24:09,480 --> 03:24:11,440 And I think we can -- 3952 03:24:11,440 --> 03:24:14,600 if we think about this for animal models, 3953 03:24:14,600 --> 03:24:18,720 this has been a challenge for reproducibility 3954 03:24:18,720 --> 03:24:20,360 on animal models from consistently. 3955 03:24:20,360 --> 03:24:24,640 If we look at, for instance, the APP-PS1 model, 3956 03:24:24,640 --> 03:24:27,200 we can see that there are multiple groups. 3957 03:24:27,200 --> 03:24:29,680 There's maybe over 1,000 papers 3958 03:24:29,680 --> 03:24:33,720 or so that describe this model and characterize it. 3959 03:24:33,720 --> 03:24:37,200 But multiple groups show early age-dependent changes 3960 03:24:37,200 --> 03:24:39,200 at three or four months of age, or even five months of age, 3961 03:24:39,200 --> 03:24:41,000 they show memory deficits where other groups don't show it 3962 03:24:41,000 --> 03:24:44,720 'till they're 12 months of age, or even 18 months of age. 3963 03:24:44,720 --> 03:24:48,800 Same mouse, same background, same experiment. 3964 03:24:48,800 --> 03:24:51,000 The environment may play a big role in this, 3965 03:24:51,000 --> 03:24:54,320 and this may be the handling of the mice. 3966 03:24:54,320 --> 03:24:58,760 And how this can be addressed, I'm not really sure. 3967 03:24:58,760 --> 03:25:00,320 But, take suggestions. 3968 03:25:00,320 --> 03:25:02,360 But I think that age is really going to be a key factor 3969 03:25:02,360 --> 03:25:03,920 with this understanding this, too. 3970 03:25:03,920 --> 03:25:06,000 And that's going to be hypothesis-driven for LATE. 3971 03:25:06,000 --> 03:25:08,000 And that's going to be up to the researcher. 3972 03:25:08,000 --> 03:25:12,080 We're suggesting single copy, maybe endogenous promoter, 3973 03:25:12,080 --> 03:25:17,840 inducible expression, or other approaches to replicate LATE. 3974 03:25:17,840 --> 03:25:25,000 Next slide, please. Next slide, please. Thank you. 3975 03:25:25,000 --> 03:25:28,200 So, this is an overview of the recommendation 3976 03:25:28,200 --> 03:25:29,800 is to build new experimental models, 3977 03:25:29,800 --> 03:25:32,760 and incorporate aging behavioral pathological phenotype. 3978 03:25:32,760 --> 03:25:35,000 And I talked about developing and characterizing models 3979 03:25:35,000 --> 03:25:38,920 that incorporate aging, designated to -- 3980 03:25:38,920 --> 03:25:42,680 designed to simulate latency. 3981 03:25:42,680 --> 03:25:44,080 Barley transduce models knock in, 3982 03:25:44,080 --> 03:25:46,000 gene-editing stress models, transgenic models 3983 03:25:46,000 --> 03:25:49,200 that express to the wild-type or mutant TDP 43. 3984 03:25:49,200 --> 03:25:51,440 Consider using inducible promoters 3985 03:25:51,440 --> 03:25:55,920 to derive expression, disease relevant cells. 3986 03:25:55,920 --> 03:25:57,480 But attention has to be played 3987 03:25:57,480 --> 03:25:59,920 to the appropriate time of life in the animal. 3988 03:25:59,920 --> 03:26:01,400 The vascular contribution 3989 03:26:01,400 --> 03:26:03,800 to TDP 43 proteinopathy hippocampal sclerosis 3990 03:26:03,800 --> 03:26:05,320 is going to be important to develop, too, 3991 03:26:05,320 --> 03:26:08,320 as far as models. And the interaction of TDP 43 3992 03:26:08,320 --> 03:26:12,200 with other pathological proteins, 3993 03:26:12,200 --> 03:26:16,200 and understanding those pathologies is important. 3994 03:26:16,200 --> 03:26:18,920 In addition to glial neuronal interaction, 3995 03:26:18,920 --> 03:26:22,320 plus inflammatory and neuroinflammation contributions 3996 03:26:22,320 --> 03:26:26,280 to TDP proteinopathy to be able to model this in -- 3997 03:26:26,280 --> 03:26:29,240 they're replicates of what's seen in LATE, 3998 03:26:29,240 --> 03:26:30,680 specifically in aging. 3999 03:26:30,680 --> 03:26:32,840 And then study the prion-like transmission 4000 03:26:32,840 --> 03:26:35,040 of pathological TDP 43 species 4001 03:26:35,040 --> 03:26:40,800 that simulate anatomical progression of latency. 4002 03:26:40,800 --> 03:26:42,120 With this structure now, 4003 03:26:42,120 --> 03:26:45,480 we may be able to develop good candidates 4004 03:26:45,480 --> 03:26:47,040 for different areas of the protein, 4005 03:26:47,040 --> 03:26:49,000 in order to induce these changes. 4006 03:26:49,000 --> 03:26:50,440 Maybe starting it in the amygdala, 4007 03:26:50,440 --> 03:26:53,000 and seeing how the transmission progresses. 4008 03:26:53,000 --> 03:26:55,200 Next slide, please. 4009 03:26:55,200 --> 03:26:57,600 -Two minutes remaining. 4010 03:26:57,600 --> 03:26:59,200 -Next slide, please. 4011 03:27:01,640 --> 03:27:03,200 So, in general, we want to develop 4012 03:27:03,200 --> 03:27:05,840 translationally actual cellular and animal models, 4013 03:27:05,840 --> 03:27:08,200 to enable preclinical therapeutic development, 4014 03:27:08,200 --> 03:27:10,480 and testing pipelines and latency. 4015 03:27:10,480 --> 03:27:14,120 Most of the models to date focus on ALS or FTLD. 4016 03:27:14,120 --> 03:27:16,000 And we've just seen we really need models 4017 03:27:16,000 --> 03:27:19,360 that replicate LATE, and other models of LATE. 4018 03:27:19,360 --> 03:27:21,520 Not just animal models, but other models 4019 03:27:21,520 --> 03:27:26,680 [Indistinct] as well. 4020 03:27:26,680 --> 03:27:29,920 We need to study this in the context of multiple pathologies. 4021 03:27:29,920 --> 03:27:32,080 It's important to look at these interactions 4022 03:27:32,080 --> 03:27:34,600 in more of a complex nature with TDP 43, 4023 03:27:34,600 --> 03:27:36,360 as we're seeing it in the human disease. 4024 03:27:36,360 --> 03:27:39,400 And we may be able to model it better 4025 03:27:39,400 --> 03:27:42,800 by looking in more pathological proteins in that. 4026 03:27:42,800 --> 03:27:45,160 And then what's real important is the intersection 4027 03:27:45,160 --> 03:27:47,960 with the hippocampal atrophy and vascular disease, 4028 03:27:47,960 --> 03:27:51,960 and developmental models or other systems as well. 4029 03:27:51,960 --> 03:27:53,400 But in all of the models, 4030 03:27:53,400 --> 03:27:56,080 aging should be incorporated in everything, 4031 03:27:56,080 --> 03:27:58,400 as far as I understand. 4032 03:27:58,400 --> 03:28:01,240 I want to thank you for your time. 4033 03:28:01,240 --> 03:28:05,240 And the next part will be the Open Mic and Questions. 4034 03:28:05,240 --> 03:28:06,840 Thank you very much. 4035 03:28:11,920 --> 03:28:14,360 -Thank you so much. 4036 03:28:14,360 --> 03:28:18,800 So, we have a question from Penny Dacks. 4037 03:28:24,200 --> 03:28:25,840 -Thank you all. 4038 03:28:25,840 --> 03:28:29,000 I've got to say, I learned so much listening to all of you. 4039 03:28:29,000 --> 03:28:31,400 And I deeply appreciate your work here, 4040 03:28:31,400 --> 03:28:34,800 and your leadership in this space. 4041 03:28:34,800 --> 03:28:37,480 I was -- you know, Dr. Gitcho just spoke on the models. 4042 03:28:37,480 --> 03:28:40,640 And I think his -- and supplied your ability 4043 03:28:40,640 --> 03:28:43,640 to convey so much complexities about how do we -- 4044 03:28:43,640 --> 03:28:45,480 when we take the complexities 4045 03:28:45,480 --> 03:28:46,800 and we try to distill it into models, 4046 03:28:46,800 --> 03:28:48,200 sometimes we go too far. 4047 03:28:48,200 --> 03:28:49,680 And I think you did such a phenomenal job 4048 03:28:49,680 --> 03:28:51,920 discussing how there's so many different ways 4049 03:28:51,920 --> 03:28:54,200 that we can be using the models in a deeper way, 4050 03:28:54,200 --> 03:28:57,600 to be looking at the interaction of factors, 4051 03:28:57,600 --> 03:29:03,160 rather than solely distilling them down into singular ways. 4052 03:29:03,160 --> 03:29:05,120 I want to encourage the group to consider 4053 03:29:05,120 --> 03:29:07,600 looking at long-term sleep impairments as well, 4054 03:29:07,600 --> 03:29:09,040 because I do think there's a lot 4055 03:29:09,040 --> 03:29:10,760 that's there that we don't fully understand 4056 03:29:10,760 --> 03:29:13,360 when you're going at aging biology. 4057 03:29:13,360 --> 03:29:16,400 And, in general, systems biology and computational models 4058 03:29:16,400 --> 03:29:19,360 I think are important to consider. 4059 03:29:19,360 --> 03:29:21,680 But my core suggestion is, really, 4060 03:29:21,680 --> 03:29:24,920 just to emphasize the broader mixed etiologies 4061 03:29:24,920 --> 03:29:26,600 dementia recommendation at round, 4062 03:29:26,600 --> 03:29:30,760 building proactively towards harmonized data 4063 03:29:30,760 --> 03:29:32,800 and biosample collection, 4064 03:29:32,800 --> 03:29:35,800 so that the work that's happening on TDP 4065 03:29:35,800 --> 03:29:39,600 43 within all of the ADRDs, as well as related fields like 4066 03:29:39,600 --> 03:29:43,760 ALS, can really be able to benefit from each other. 4067 03:29:43,760 --> 03:29:45,120 We don't yet know, 4068 03:29:45,120 --> 03:29:46,640 and I don't think we'll know for a long time, 4069 03:29:46,640 --> 03:29:49,600 how much, you know, the biomarker work in one space, 4070 03:29:49,600 --> 03:29:51,880 or the basic science work in one space 4071 03:29:51,880 --> 03:29:55,000 is actually going to be relevant to a related space. 4072 03:29:55,000 --> 03:29:57,560 And I hope that one day we can get to the place 4073 03:29:57,560 --> 03:30:01,200 where our clinical phenotypes are being very carefully 4074 03:30:01,200 --> 03:30:03,800 and [Indistinct] characterized for prognosis, 4075 03:30:03,800 --> 03:30:07,080 but that the underlying molecular pathology 4076 03:30:07,080 --> 03:30:09,560 is what is being defined in individuals, 4077 03:30:09,560 --> 03:30:11,400 so that that is what can be tackled 4078 03:30:11,400 --> 03:30:17,040 clinically with new therapies. Thank you all. 4079 03:30:17,040 --> 03:30:20,720 -Thank you so much. Those are great points. 4080 03:30:20,720 --> 03:30:22,520 And I've written them all down. 4081 03:30:22,520 --> 03:30:26,400 I think the harmonization is super important. 4082 03:30:26,400 --> 03:30:30,160 And I think we do have that in some of our bullets, 4083 03:30:30,160 --> 03:30:34,920 as far as recognizing that need for harmonization, 4084 03:30:34,920 --> 03:30:36,400 as well as this intersection 4085 03:30:36,400 --> 03:30:38,600 with frontotemporal lower degeneration, 4086 03:30:38,600 --> 03:30:40,800 harmonization with other diseases 4087 03:30:40,800 --> 03:30:46,080 that might be in their own isolated coves. 4088 03:30:46,080 --> 03:30:48,240 Eric, Eric Smith? 4089 03:30:50,440 --> 03:30:53,200 -Yes, Thanks, Julie. My question is, 4090 03:30:53,200 --> 03:30:59,320 "Are we ready for provisional diagnostic criteria 4091 03:30:59,320 --> 03:31:02,840 in vivo like probable or possible LATE?" 4092 03:31:02,840 --> 03:31:05,040 I'm a neurologist and a clinician scientist. 4093 03:31:05,040 --> 03:31:07,440 I think I recognize this syndrome sometimes, 4094 03:31:07,440 --> 03:31:10,320 or a pattern like what was described, right, 4095 03:31:10,320 --> 03:31:12,600 with the slowly progressive amnestic syndrome. 4096 03:31:12,600 --> 03:31:14,160 And I was encouraged to see all the work 4097 03:31:14,160 --> 03:31:19,800 on like hippocampal volumes and patterns of atrophy. 4098 03:31:19,800 --> 03:31:22,160 Are we ready to try to identify prospectively, 4099 03:31:22,160 --> 03:31:25,400 and then follow people and validate 4100 03:31:25,400 --> 03:31:27,200 pathologically? Thanks. 4101 03:31:27,200 --> 03:31:28,800 -David? 4102 03:31:31,120 --> 03:31:33,240 -Thanks so much for the question. 4103 03:31:33,240 --> 03:31:36,360 And I'll be interested to hear what other panelists say. 4104 03:31:36,360 --> 03:31:39,240 I do think there are cases that we see clinically 4105 03:31:39,240 --> 03:31:42,680 that I feel fairly comfortable nowadays, 4106 03:31:42,680 --> 03:31:45,640 particularly if we have rich biomarker data 4107 03:31:45,640 --> 03:31:49,200 for classifying them, as having LATE. 4108 03:31:49,200 --> 03:31:54,120 I think, LATE alone has relatively distinctive features 4109 03:31:54,120 --> 03:31:55,360 associated with it, 4110 03:31:55,360 --> 03:31:58,800 that we probably could create criteria, 4111 03:31:58,800 --> 03:32:01,440 that, again, probabilistically would give us 4112 03:32:01,440 --> 03:32:06,680 a reasonable degree of certainty about the underlying pathology. 4113 03:32:06,680 --> 03:32:08,480 I think, in the context of Alzheimer's disease, 4114 03:32:08,480 --> 03:32:10,320 it obviously gets trickier. 4115 03:32:10,320 --> 03:32:14,080 But, again, I think there are features in the imaging, 4116 03:32:14,080 --> 03:32:19,120 as well as cognitively, that may allow us, again, 4117 03:32:19,120 --> 03:32:20,640 to kind of probabilistically say 4118 03:32:20,640 --> 03:32:25,840 there's a high likelihood of LATE copathology. 4119 03:32:25,840 --> 03:32:28,320 But I'll let the others weigh in as well. 4120 03:32:30,440 --> 03:32:32,200 -David? 4121 03:32:32,200 --> 03:32:34,680 -This is a great session. Thanks for doing this so far. 4122 03:32:34,680 --> 03:32:36,640 I was going to comment on the issue 4123 03:32:36,640 --> 03:32:39,000 that I think it's going to be very difficult 4124 03:32:39,000 --> 03:32:42,800 actually to study this in live people 4125 03:32:42,800 --> 03:32:45,000 without a marker of the pathology. 4126 03:32:45,000 --> 03:32:46,400 And I think, until we get there, 4127 03:32:46,400 --> 03:32:48,760 it's going to be where we can rule out 4128 03:32:48,760 --> 03:32:51,200 AD pathology with biomarkers or in. 4129 03:32:51,200 --> 03:32:55,320 But I just would feel very uncomfortable 4130 03:32:55,320 --> 03:32:56,800 diagnosing somebody with this, 4131 03:32:56,800 --> 03:33:00,400 with the current information that we have. 4132 03:33:00,400 --> 03:33:03,400 Now that we have cryo-EM of TDP 43 structure, I mean, 4133 03:33:03,400 --> 03:33:05,280 you theoretically should be able 4134 03:33:05,280 --> 03:33:07,640 to develop an imaging agent for it. 4135 03:33:09,800 --> 03:33:11,360 At least in the patients I see that. 4136 03:33:11,360 --> 03:33:13,200 I mean, most patients who come to clinic, 4137 03:33:13,200 --> 03:33:15,800 not research, don't even get AD biomarkers, 4138 03:33:15,800 --> 03:33:18,840 let alone anything else, so... 4139 03:33:18,840 --> 03:33:20,400 -Right. So, yeah. 4140 03:33:20,400 --> 03:33:21,840 Yeah, I think that's a great point. 4141 03:33:21,840 --> 03:33:23,520 I mean, you know, in the population-based 4142 03:33:23,520 --> 03:33:25,520 studies and community-based studies, 4143 03:33:25,520 --> 03:33:27,280 it would be exceedingly hard to do. 4144 03:33:27,280 --> 03:33:31,400 It would definitely have to be a research study with biomarkers. 4145 03:33:31,400 --> 03:33:33,320 Pete? 4146 03:33:33,320 --> 03:33:34,440 -Thank you very much to everybody. 4147 03:33:34,440 --> 03:33:36,160 Thank you, Dr. Schneider. 4148 03:33:36,160 --> 03:33:39,560 And I agree with both David's points 4149 03:33:39,560 --> 03:33:41,400 that we need better biomarkers. 4150 03:33:41,400 --> 03:33:43,080 However, there are a lot of people 4151 03:33:43,080 --> 03:33:46,040 now that are getting screened for AD. 4152 03:33:46,040 --> 03:33:49,200 And when they have some degree of neurodegeneration, 4153 03:33:49,200 --> 03:33:52,600 or some cognitive wobbling, but they screen failed, 4154 03:33:52,600 --> 03:33:55,800 there's no option for them. That's it. They're done. 4155 03:33:55,800 --> 03:33:58,400 And we've seen that from the patient advocacy 4156 03:33:58,400 --> 03:34:01,400 here that there's a lot of frustration with that. 4157 03:34:01,400 --> 03:34:03,040 Well, here at University of Kentucky, 4158 03:34:03,040 --> 03:34:07,000 we have what I think is the first LATE clinical trial. 4159 03:34:07,000 --> 03:34:11,600 And, so, we can employ the information of screen 4160 03:34:11,600 --> 03:34:13,880 failing for an AD clinical trial, 4161 03:34:13,880 --> 03:34:15,600 and give somebody an option. 4162 03:34:15,600 --> 03:34:18,200 And I really think that what I believe 4163 03:34:18,200 --> 03:34:20,680 I'm hearing from the patients, patient advocacy, 4164 03:34:20,680 --> 03:34:23,080 is a little bit of a disconnect to what I'm hearing 4165 03:34:23,080 --> 03:34:26,120 in the AD dementia neurology field 4166 03:34:26,120 --> 03:34:28,440 of trying to be a little bit more proactive 4167 03:34:28,440 --> 03:34:30,280 about giving patients options. 4168 03:34:30,280 --> 03:34:33,120 It's not telling them what to do, but giving them options. 4169 03:34:33,120 --> 03:34:37,520 And to try to get shots on goal, to see if we can't start to bend 4170 03:34:37,520 --> 03:34:39,200 some of the cognitive trajectories 4171 03:34:39,200 --> 03:34:40,840 in the survival curves. 4172 03:34:40,840 --> 03:34:47,400 So, for us, we have people that are clearly cognitively 4173 03:34:47,400 --> 03:34:51,000 not totally intact, and having some MRI changes, 4174 03:34:51,000 --> 03:34:54,400 but are negative on the amyloid biomarkers. 4175 03:34:54,400 --> 03:34:58,800 And we have an option for them to get into clinical research. 4176 03:34:58,800 --> 03:35:00,400 And at least it's a start. 4177 03:35:00,400 --> 03:35:02,760 And, so, I think that that's a really important -- 4178 03:35:02,760 --> 03:35:07,920 at least trying to get on the hill of effectiveness. 4179 03:35:07,920 --> 03:35:09,400 Other areas of research, like cancer, 4180 03:35:09,400 --> 03:35:11,320 have been much more proactive, 4181 03:35:11,320 --> 03:35:15,040 and have reflectively gotten much better results 4182 03:35:15,040 --> 03:35:18,040 than we have in the dementia research field. 4183 03:35:18,040 --> 03:35:20,400 -Thank you, Pete. David, did you want to respond? 4184 03:35:20,400 --> 03:35:25,600 -Yeah, I agree with, actually, both David and Pete. 4185 03:35:25,600 --> 03:35:27,800 And I think they are great points. 4186 03:35:27,800 --> 03:35:32,800 I think, to David's point about clinical practice, 4187 03:35:32,800 --> 03:35:34,840 in general clinical practice I do think it -- 4188 03:35:34,840 --> 03:35:37,000 you know, we just don't get the biomarkers 4189 03:35:37,000 --> 03:35:39,480 to make the diagnosis there. 4190 03:35:39,480 --> 03:35:43,840 But I do think that we can establish some criteria 4191 03:35:43,840 --> 03:35:45,320 in research cohorts. 4192 03:35:45,320 --> 03:35:49,960 And, again, that is kind of a goal of this, 4193 03:35:49,960 --> 03:35:54,120 you know, committee is to push for more harmonized data 4194 03:35:54,120 --> 03:35:58,240 collection across different studies and populations. 4195 03:35:58,240 --> 03:36:01,160 And I think that will ultimately allow us, again, 4196 03:36:01,160 --> 03:36:04,000 probabilistically, just like how we used to diagnose 4197 03:36:04,000 --> 03:36:06,720 Alzheimer's disease in the past, 4198 03:36:06,720 --> 03:36:10,400 to, you know, allow us to at least classify individuals, 4199 03:36:10,400 --> 03:36:12,800 perhaps incorporate genomics 4200 03:36:12,800 --> 03:36:17,000 and other factors that also help stratify individuals, 4201 03:36:17,000 --> 03:36:19,880 and their likelihood of -- the point's obviously well taken 4202 03:36:19,880 --> 03:36:24,040 that we really do need a molecularly specific biomarker 4203 03:36:24,040 --> 03:36:28,480 to truly move the needle forward. 4204 03:36:28,480 --> 03:36:29,760 -Dave? David? 4205 03:36:29,760 --> 03:36:31,320 -Yeah, I think we should 4206 03:36:31,320 --> 03:36:33,000 definitely be enrolling all people 4207 03:36:33,000 --> 03:36:36,480 who might have LATE into our research studies for sure. 4208 03:36:36,480 --> 03:36:38,040 I mean, one possibility would be 4209 03:36:38,040 --> 03:36:41,600 if you think somebody has LATE based on other criteria, 4210 03:36:41,600 --> 03:36:43,120 on all the criteria you discussed, 4211 03:36:43,120 --> 03:36:45,600 I mean, maybe there can be clinical trials 4212 03:36:45,600 --> 03:36:47,160 done in those for people, 4213 03:36:47,160 --> 03:36:52,200 if the target is not necessarily, you know, TDP 43, 4214 03:36:52,200 --> 03:36:54,800 but something that is present in everybody, 4215 03:36:54,800 --> 03:36:57,600 that you might try to hit, 4216 03:36:57,600 --> 03:36:58,920 but they wouldn't be in an AD trial, 4217 03:36:58,920 --> 03:37:00,720 because they don't have AD. 4218 03:37:00,720 --> 03:37:02,000 -Right. -Right. 4219 03:37:02,000 --> 03:37:03,320 So, not specifically amyloid or tau, 4220 03:37:03,320 --> 03:37:04,400 but if it's an inflammatory -- -Right. 4221 03:37:04,400 --> 03:37:05,600 -Mechanism or something else. 4222 03:37:05,600 --> 03:37:07,800 -Right. Exactly. 4223 03:37:07,800 --> 03:37:11,600 -Right. No, those are all great points. 4224 03:37:11,600 --> 03:37:13,080 And, interestingly, you know, 4225 03:37:13,080 --> 03:37:17,160 this intersection between TDP and vascular, 4226 03:37:17,160 --> 03:37:19,840 I think is going to become more and more important. 4227 03:37:19,840 --> 03:37:21,240 And I think -- you know, 4228 03:37:21,240 --> 03:37:24,240 we have Maria on our team with the 90+ Study. 4229 03:37:24,240 --> 03:37:26,200 And I know from our cohorts, you know, 4230 03:37:26,200 --> 03:37:28,160 in those over 90, what are we seeing? 4231 03:37:28,160 --> 03:37:30,800 We're seeing TDP and vascular disease. 4232 03:37:30,800 --> 03:37:34,920 So, it's very common. It's going to be increasing. 4233 03:37:34,920 --> 03:37:36,400 The neurologists are going to see more 4234 03:37:36,400 --> 03:37:39,000 and more of these cases as time goes on. 4235 03:37:39,000 --> 03:37:43,400 This is not going away. So, yeah. 4236 03:37:43,400 --> 03:37:51,920 Anyway, the last comment I think was from Susanne Van Veluw. 16 4237 03:37:51,920 --> 03:37:53,560 -Thanks, Julie. Yeah, to your point, actually, 4238 03:37:53,560 --> 03:37:55,960 Julie, you mentioned a role in the intersection 4239 03:37:55,960 --> 03:37:57,880 between TDP 43 and vascular disease. 4240 03:37:57,880 --> 03:38:00,600 And I wonder might there be a role for impaired 4241 03:38:00,600 --> 03:38:02,600 perivascular clearance as a disease mechanism. 4242 03:38:02,600 --> 03:38:05,800 We heard a great deal about it yesterday in the VCID section. 4243 03:38:05,800 --> 03:38:07,480 And I was wondering if that could be 4244 03:38:07,480 --> 03:38:09,400 another potential causal mechanism 4245 03:38:09,400 --> 03:38:11,560 that's worth considering as a focus of interest. 4246 03:38:11,560 --> 03:38:13,240 And, if so, if you agree 4247 03:38:13,240 --> 03:38:17,600 if that be a good addition to the recommendations. 4248 03:38:17,600 --> 03:38:21,400 -So, does anybody on the team want to take that one? 4249 03:38:24,360 --> 03:38:27,800 No, perivascular clearance mechanism people on our team? 4250 03:38:27,800 --> 03:38:32,440 I, personally, think it's a great idea. 4251 03:38:32,440 --> 03:38:35,280 You know, there's huge interest in the vascular field. 4252 03:38:35,280 --> 03:38:36,920 And I don't know if Donna's still on, 4253 03:38:36,920 --> 03:38:39,600 but she was part of our team. 4254 03:38:39,600 --> 03:38:44,800 The perivascular clearance is, you know, highly topical 4255 03:38:44,800 --> 03:38:49,000 in the vascular disease, VCID, session. 4256 03:38:49,000 --> 03:38:51,240 And, certainly, when we talk about this intersection 4257 03:38:51,240 --> 03:38:54,040 between neurodegenerative disease and vascular disease, 4258 03:38:54,040 --> 03:38:56,120 especially small vessel disease, 4259 03:38:56,120 --> 03:38:58,520 I think it is something that we should highlight. 4260 03:38:58,520 --> 03:39:00,320 So, I appreciate the comment. 4261 03:39:00,320 --> 03:39:02,080 And I think we should highlight that. 4262 03:39:02,080 --> 03:39:05,920 And we can discuss it among our committee. 4263 03:39:05,920 --> 03:39:08,960 -Just to add, Julie. Hi, everyone. 4264 03:39:08,960 --> 03:39:11,680 So, just to follow up on that, Susanne, 4265 03:39:11,680 --> 03:39:15,400 you know, when we talk about the perivascular 4266 03:39:15,400 --> 03:39:19,600 kind of drainage pathways in the VCID recommendations, 4267 03:39:19,600 --> 03:39:21,160 we talk about solutes, 4268 03:39:21,160 --> 03:39:24,920 and, you know, neurodegenerative proteins. 4269 03:39:24,920 --> 03:39:26,720 We're not specifically talking about amyloid. 4270 03:39:26,720 --> 03:39:31,000 So, I think that does open up kind of that recommendation 4271 03:39:31,000 --> 03:39:32,960 to being draining -- 4272 03:39:32,960 --> 03:39:36,880 you know, clearance of TDP 43 clearance of other, 4273 03:39:36,880 --> 03:39:41,920 you know, proteins as well. So, yeah, it's a good point. 4274 03:39:41,920 --> 03:39:44,960 -Yeah, and maybe something we can at least touch upon 4275 03:39:44,960 --> 03:39:47,680 in our recommendations, too. 4276 03:39:47,680 --> 03:39:51,160 -Julie, very quickly, I just wanted to mention that 4277 03:39:51,160 --> 03:39:53,560 before it was mentioned that many of these 4278 03:39:53,560 --> 03:39:55,000 are age-related pathologies. 4279 03:39:55,000 --> 03:39:56,800 And one of the things that will be important 4280 03:39:56,800 --> 03:39:59,400 to kind of try to disentangle is that, 4281 03:39:59,400 --> 03:40:01,880 especially like with vascular and TDP 43, 4282 03:40:01,880 --> 03:40:03,480 are they there co-occurrent 4283 03:40:03,480 --> 03:40:06,600 because it's just a factor of age? 4284 03:40:06,600 --> 03:40:08,200 Or is it because they actually have 4285 03:40:08,200 --> 03:40:10,480 a mechanistic interaction in some way? 4286 03:40:10,480 --> 03:40:14,440 So, I think that's an important point to try to disentangle. 4287 03:40:14,440 --> 03:40:17,760 -Right. And I agree, Maria, it's really important. 4288 03:40:17,760 --> 03:40:20,200 And, you know, residual confounding 4289 03:40:20,200 --> 03:40:21,520 is certainly a possibility. 4290 03:40:21,520 --> 03:40:23,760 We controlled for age in our studies. 4291 03:40:23,760 --> 03:40:26,280 I'm sure Pete did, too. 4292 03:40:26,280 --> 03:40:28,960 And we looked at that pretty carefully. 4293 03:40:28,960 --> 03:40:31,000 But, yeah, these are people who are surviving. 4294 03:40:31,000 --> 03:40:35,080 These are people in their 90s. Right? So, you know, 4295 03:40:35,080 --> 03:40:38,080 association doesn't mean that there's causation. 4296 03:40:38,080 --> 03:40:39,600 So, that certainly is something 4297 03:40:39,600 --> 03:40:42,480 that we need to figure out still. 4298 03:40:42,480 --> 03:40:43,680 Pete? 4299 03:40:43,680 --> 03:40:45,400 -I would say -- thank you. 4300 03:40:45,400 --> 03:40:48,400 I would say a couple other things are also maybe relevant. 4301 03:40:48,400 --> 03:40:50,600 We found that arteriosclerosis connection 4302 03:40:50,600 --> 03:40:53,200 with TDP 43 and hippocampal sclerosis. 4303 03:40:53,200 --> 03:40:56,400 But Dr. Selenich's animal model, 4304 03:40:56,400 --> 03:40:59,560 where they do the viral transduction with TDP. 4305 03:40:59,560 --> 03:41:01,200 it's very interesting, because it produces 4306 03:41:01,200 --> 03:41:03,800 both an HS phenotype into mice, 4307 03:41:03,800 --> 03:41:09,400 but also perivascular sort of changes as well, 4308 03:41:09,400 --> 03:41:13,080 and gliosis that seems to be deleterious. 4309 03:41:13,080 --> 03:41:16,080 So, it seems to recapitulate 4310 03:41:16,080 --> 03:41:19,200 a number of the features of the pathology. 4311 03:41:19,200 --> 03:41:21,680 And I think Dr. Selenich's model is a very interesting one, 4312 03:41:21,680 --> 03:41:26,280 that allows both aging TDP HS-like and vascular changes. 4313 03:41:26,280 --> 03:41:30,120 So, I think it's really provocative. 4314 03:41:30,120 --> 03:41:31,720 -Thank you, Pete. 4315 03:41:31,720 --> 03:41:35,240 So, we have a question -- or a comment from Ian Premmer. 4316 03:41:37,520 --> 03:41:39,160 -Hi. 4317 03:41:39,160 --> 03:41:41,400 I think Keith wanted me on to reiterate something I -- 4318 03:41:41,400 --> 03:41:44,680 just a small comment I put in Q&A. 4319 03:41:44,680 --> 03:41:50,680 And please understand none of this in any way reduces 4320 03:41:50,680 --> 03:41:53,680 the importance of the point that Dr. Nelson made. 4321 03:41:53,680 --> 03:41:56,880 But in response to two points ago 4322 03:41:56,880 --> 03:42:01,000 that he made about the patient and family advocacy 4323 03:42:01,000 --> 03:42:02,600 community wanting more options. 4324 03:42:02,600 --> 03:42:06,240 I think that's completely true and critically important. 4325 03:42:06,240 --> 03:42:10,800 My minor quibble is I think the data is pretty clear 4326 03:42:10,800 --> 03:42:13,120 that those advocacy communities 4327 03:42:13,120 --> 03:42:17,000 are not primarily interested in extended lifespan. 4328 03:42:17,000 --> 03:42:19,680 They're primarily interested in expanded 4329 03:42:19,680 --> 03:42:21,960 health span quality of life. 4330 03:42:21,960 --> 03:42:24,520 So, those things are not at odds. 4331 03:42:24,520 --> 03:42:29,200 But the primacy is on what can be done to improve the here 4332 03:42:29,200 --> 03:42:31,200 and now in the short term, 4333 03:42:31,200 --> 03:42:35,200 even if sometimes that may be at the expense of the longer term. 4334 03:42:35,200 --> 03:42:37,600 Because it's end stage dementia 4335 03:42:37,600 --> 03:42:40,880 that scares the bejesus out of people, rightfully. 4336 03:42:40,880 --> 03:42:43,440 And where there is maximum opportunity 4337 03:42:43,440 --> 03:42:46,320 for improved quality of life, may be at earlier stages. 4338 03:42:46,320 --> 03:42:48,400 Hence, the urgency to have better 4339 03:42:48,400 --> 03:42:53,560 means of detection and diagnosis with precision. 4340 03:42:53,560 --> 03:42:55,760 Which I think goes back to Dr. Nelson's point. 4341 03:42:55,760 --> 03:42:59,000 We want options as we are working 4342 03:42:59,000 --> 03:43:00,920 toward greater precision, 4343 03:43:00,920 --> 03:43:03,600 greater accuracy, greater, therefore, 4344 03:43:03,600 --> 03:43:06,160 actionability based on a differential diagnosis. 4345 03:43:06,160 --> 03:43:09,360 So, I think I'm in complete agreement with Dr. Nelson. 4346 03:43:09,360 --> 03:43:11,680 But he is, certainly, welcome to tell me 4347 03:43:11,680 --> 03:43:15,240 if I've missed the thrust, or misrepresented his view. 4348 03:43:15,240 --> 03:43:17,600 -You a thumbs up from Pete. 4349 03:43:17,600 --> 03:43:19,600 -Thank golly. Okay. 4350 03:43:19,600 --> 03:43:21,160 -But I, also, want to point out that, 4351 03:43:21,160 --> 03:43:23,040 you know, LATE is interesting 4352 03:43:23,040 --> 03:43:25,600 in that it is very slowly progressive. 4353 03:43:25,600 --> 03:43:27,920 So, when we see people with LATE, you know, 4354 03:43:27,920 --> 03:43:29,880 they have some mild memory problems 4355 03:43:29,880 --> 03:43:31,280 that very slowly progress. 4356 03:43:31,280 --> 03:43:34,600 So, their quality of life may not decline, 4357 03:43:34,600 --> 03:43:37,640 or isn't declining as fast as people with Alzheimer's 4358 03:43:37,640 --> 03:43:42,600 or Alzheimer's plus TDP 43. So, I agree with you. 4359 03:43:42,600 --> 03:43:46,520 But I do think that there -- that that group is important. 4360 03:43:46,520 --> 03:43:47,880 David? Or Dave? 4361 03:43:47,880 --> 03:43:50,600 -Just to piggyback on top of that. 4362 03:43:50,600 --> 03:43:53,000 That's why, you know, correct diagnosis 4363 03:43:53,000 --> 03:43:55,240 is also particularly important in that group, 4364 03:43:55,240 --> 03:43:58,000 because being told that you have Alzheimer's 4365 03:43:58,000 --> 03:44:01,200 has a different connotation, at least to some patients. 4366 03:44:01,200 --> 03:44:04,480 And, so, some of these cases are more likely to be slow. 4367 03:44:04,480 --> 03:44:06,600 And I think it's important for us 4368 03:44:06,600 --> 03:44:08,960 to get the diagnosis right, so that we have a better sense 4369 03:44:08,960 --> 03:44:11,640 of what the prognosis is in those individuals. 4370 03:44:11,640 --> 03:44:13,200 -If I could just add one more quick point, 4371 03:44:13,200 --> 03:44:17,280 you know, following on piggybacking on that point. 4372 03:44:17,280 --> 03:44:20,400 There is -- often, I think we all are sensitive to this, 4373 03:44:20,400 --> 03:44:23,000 a lot of prescription nihilism. 4374 03:44:23,000 --> 03:44:27,720 And it's misplaced, because so many people, not all, 4375 03:44:27,720 --> 03:44:32,000 but so many people in the patient and family communities 4376 03:44:32,000 --> 03:44:35,400 want to know what we are facing, and what we aren't, 4377 03:44:35,400 --> 03:44:39,160 even in the absence of, never mind a cure, 4378 03:44:39,160 --> 03:44:42,120 even an effective disease-modifying treatment, 4379 03:44:42,120 --> 03:44:43,640 or even a symptomatic treatment. 4380 03:44:43,640 --> 03:44:46,600 It just helps to be able to put a name to it. 4381 03:44:46,600 --> 03:44:49,000 Or in the case of multiple etiology, 4382 03:44:49,000 --> 03:44:52,400 mixed dementias, put names on them. 4383 03:44:52,400 --> 03:44:54,640 So, we know what we're facing, we know what we're not. 4384 03:44:54,640 --> 03:44:57,640 And, so, we can enroll in the right clinical trials, 4385 03:44:57,640 --> 03:45:02,840 if we are privileged enough to have access to trials at all. 4386 03:45:02,840 --> 03:45:05,200 -I agree. Pete? 4387 03:45:05,200 --> 03:45:07,080 -And this is just something to make a point 4388 03:45:07,080 --> 03:45:08,920 about that, actually, 4389 03:45:08,920 --> 03:45:11,720 in Dr. Schneider's excellent introductory talk was made. 4390 03:45:11,720 --> 03:45:16,880 But it needs to be underscored that you think about LATE or AD 4391 03:45:16,880 --> 03:45:19,440 and C, but they're frequently combined. 4392 03:45:19,440 --> 03:45:23,200 Not only is it such that LATE is a little bit more mellow 4393 03:45:23,200 --> 03:45:24,800 than AD per se. 4394 03:45:24,800 --> 03:45:27,680 And the combination is worse than either alone. 4395 03:45:27,680 --> 03:45:30,280 Which is intuitive. But the very important point 4396 03:45:30,280 --> 03:45:32,600 that Dr. Schneider's data 4397 03:45:32,600 --> 03:45:34,800 showed better than anybody's in the world 4398 03:45:34,800 --> 03:45:37,400 is that pure LATE is the least common, 4399 03:45:37,400 --> 03:45:39,240 but it's still quite common. 4400 03:45:39,240 --> 03:45:42,080 Pure AD is a little bit more common, 4401 03:45:42,080 --> 03:45:43,760 I mean, significantly more common. 4402 03:45:43,760 --> 03:45:46,360 But even more common than that is the combination. 4403 03:45:46,360 --> 03:45:50,600 So, this combination is where LATE actually exerts itself, 4404 03:45:50,600 --> 03:45:54,200 and where it's a bedevilment for the clinical trials as well. 4405 03:45:54,200 --> 03:45:56,880 So, I think that more people need to be much more aware 4406 03:45:56,880 --> 03:45:58,640 of this combination, 4407 03:45:58,640 --> 03:46:02,880 because it's the most common and the most impactful of them. 4408 03:46:02,880 --> 03:46:07,400 And, so, we need to have better therapeutics and diagnostics 4409 03:46:07,400 --> 03:46:10,760 for both of those scenarios. 4410 03:46:10,760 --> 03:46:13,200 -And awareness across research, 4411 03:46:13,200 --> 03:46:16,800 as well as non-research communities. 4412 03:46:16,800 --> 03:46:18,680 -Thank you for a wonderful session. 4413 03:46:18,680 --> 03:46:21,400 I think we probably need to stop there, 4414 03:46:21,400 --> 03:46:23,480 unless anybody has a burning comment 4415 03:46:23,480 --> 03:46:27,320 they'd like to finish off with. 4416 03:46:27,320 --> 03:46:31,040 We're going to go ahead and restart at 2:25 4417 03:46:31,040 --> 03:46:36,480 with the Special Session on COVID-19 and AD/ADRD. 4418 03:46:36,480 --> 03:46:39,560 So, thank you so much, everyone. And we'll see you back soon. 4419 03:46:42,080 --> 03:46:43,560 We're going to start the next session 4420 03:46:43,560 --> 03:46:46,840 of this ADRD Summit 2022. 4421 03:46:46,840 --> 03:46:50,320 It gives me great pleasure to introduce the Scientific Chair 4422 03:46:50,320 --> 03:46:52,440 of the meeting, Dr. Natalia Rost, 4423 03:46:52,440 --> 03:46:54,280 who will bring us into the session 4424 03:46:54,280 --> 03:46:59,920 on impact of COVID-19 on AD/ADRD risk and outcomes. 4425 03:46:59,920 --> 03:47:01,360 -Thank you, Rod. 4426 03:47:01,360 --> 03:47:04,640 Homestretch, everybody. That's the last session, 4427 03:47:04,640 --> 03:47:06,880 last scientific session of the meeting, 4428 03:47:06,880 --> 03:47:09,320 before the general and the closing. 4429 03:47:09,320 --> 03:47:12,560 And we're excited as part of this new working group 4430 03:47:12,560 --> 03:47:16,640 brings to you a topic that is of most urgency 4431 03:47:16,640 --> 03:47:21,920 and necessity to investigate in deeper detail. 4432 03:47:21,920 --> 03:47:27,000 Namely, the impact of COVID-19 on ADRD risk and outcomes. 4433 03:47:27,000 --> 03:47:31,720 And I'm delighted to pass the baton to my Co-Chair, 4434 03:47:31,720 --> 03:47:33,640 Dr. Sudha Seshardi, 4435 03:47:33,640 --> 03:47:35,920 who is Director of the Glenn Biggs 4436 03:47:35,920 --> 03:47:38,880 Institute for Alzheimer's and Neurodegenerative Diseases 4437 03:47:38,880 --> 03:47:41,040 at the University of Texas San Antonio. 4438 03:47:41,040 --> 03:47:42,640 Sudha? 4439 03:47:42,640 --> 03:47:44,360 -Thank you, Natalia. 4440 03:47:44,360 --> 03:47:48,960 And it's my distinct honor and privilege to work with you, 4441 03:47:48,960 --> 03:47:53,240 and with an outstanding team of diverse experts, 4442 03:47:53,240 --> 03:47:57,200 to address this important emerging topic on COVID 4443 03:47:57,200 --> 03:48:01,520 impact on AD/ADRD risks and outcomes. 4444 03:48:01,520 --> 03:48:04,440 So, I'll touch upon the introduction, 4445 03:48:04,440 --> 03:48:06,200 scope of the problem, 4446 03:48:06,200 --> 03:48:10,200 and the recommendations that this working group arrived at. 4447 03:48:10,200 --> 03:48:12,360 And then colleagues in the group 4448 03:48:12,360 --> 03:48:16,800 will expand on our thinking behind these recommendations, 4449 03:48:16,800 --> 03:48:18,600 and what we know at present 4450 03:48:18,600 --> 03:48:22,960 about different aspects of this infection. Next. 4451 03:48:25,000 --> 03:48:28,240 These are the opinions of myself and our committee, 4452 03:48:28,240 --> 03:48:32,480 and not official NIH policy. And this is my disclosure. 4453 03:48:32,480 --> 03:48:36,640 Next. And we have -- 4454 03:48:36,640 --> 03:48:40,800 I have to extend thanks to all the outstanding members 4455 03:48:40,800 --> 03:48:45,200 who served on this committee, three of whom will be speaking, 4456 03:48:45,200 --> 03:48:48,600 as I do, on behalf of the whole group. 4457 03:48:48,600 --> 03:48:53,040 They pulled together in a very short time. Next. 4458 03:48:55,400 --> 03:49:00,560 And we were charged with making four recommendations. 4459 03:49:00,560 --> 03:49:06,360 And we ordered them in the order in which we thought, logically, 4460 03:49:06,360 --> 03:49:10,840 these need to be done. But all are equally important. 4461 03:49:10,840 --> 03:49:17,200 And we are recommending that all of them be addressed right away. 4462 03:49:17,200 --> 03:49:19,600 Although they may continue to be addressed 4463 03:49:19,600 --> 03:49:21,560 for varying periods of time. 4464 03:49:21,560 --> 03:49:23,960 The first priority the group emphasized 4465 03:49:23,960 --> 03:49:26,760 was the need for research infrastructure 4466 03:49:26,760 --> 03:49:28,200 to be established, 4467 03:49:28,200 --> 03:49:31,360 infrastructure in clinical, epidemiological 4468 03:49:31,360 --> 03:49:36,080 and basic research studies of the COVID-19 impact on ADRD. 4469 03:49:36,080 --> 03:49:39,200 Prioritizing disproportionately affected 4470 03:49:39,200 --> 03:49:41,960 and vulnerable populations with a view 4471 03:49:41,960 --> 03:49:44,080 to having clinical trial readiness 4472 03:49:44,080 --> 03:49:46,480 as quickly as possible. 4473 03:49:46,480 --> 03:49:49,960 So, for this, we believe the second recommendation 4474 03:49:49,960 --> 03:49:54,120 was to focus on characterizing the clinical phenotype 4475 03:49:54,120 --> 03:49:59,640 of neurocognitive consequences of COVID-19, 4476 03:49:59,640 --> 03:50:04,160 and developing diagnostic criteria, 4477 03:50:04,160 --> 03:50:07,920 both in persons with and those without 4478 03:50:07,920 --> 03:50:11,360 pre-existing neurocognitive impairment and dementia 4479 03:50:11,360 --> 03:50:13,920 at the time that they became infected. 4480 03:50:13,920 --> 03:50:16,680 The third priority was to recognize 4481 03:50:16,680 --> 03:50:18,960 that this is a complex issue, 4482 03:50:18,960 --> 03:50:23,080 and explore the interaction with social, structural 4483 03:50:23,080 --> 03:50:27,080 and systemic inequalities, comorbidities, 4484 03:50:27,080 --> 03:50:29,760 and social and medical interventions, 4485 03:50:29,760 --> 03:50:33,160 both the access and specifics of the interventions, 4486 03:50:33,160 --> 03:50:35,920 on the risk and cognitive -- sequelae 4487 03:50:35,920 --> 03:50:40,160 of neurocognitive deficits after COVID-19. 4488 03:50:40,160 --> 03:50:42,840 And equally important was to understand 4489 03:50:42,840 --> 03:50:47,200 the basic mechanisms underlying this neurocognitive impairment, 4490 03:50:47,200 --> 03:50:51,160 so that we can develop appropriate biomarkers, 4491 03:50:51,160 --> 03:50:53,240 establish risk profiles, 4492 03:50:53,240 --> 03:50:56,680 and lay the foundation for early interventional trials. 4493 03:50:56,680 --> 03:51:01,000 Next. Next. 4494 03:51:01,000 --> 03:51:04,240 So, I'll be touching on the epidemiology and biology 4495 03:51:04,240 --> 03:51:07,800 as we know of SARS CoV-2, why we think there may be 4496 03:51:07,800 --> 03:51:11,720 an excess of this pandemic with AD/ADRD, 4497 03:51:11,720 --> 03:51:13,800 and what are the types of infrastructure 4498 03:51:13,800 --> 03:51:15,480 we are talking about. 4499 03:51:15,480 --> 03:51:18,600 And my colleagues, Professor Avindra Nath 4500 03:51:18,600 --> 03:51:21,880 from the NIH will address neuropathology, 4501 03:51:21,880 --> 03:51:24,280 Professor Gabriel de Erausquin 4502 03:51:24,280 --> 03:51:26,320 will address the clinical spectrum 4503 03:51:26,320 --> 03:51:29,120 and the modifying systemic factors, 4504 03:51:29,120 --> 03:51:31,800 and Professor Serena Spudich from Yale 4505 03:51:31,800 --> 03:51:36,760 will speak about biomarkers and possible promising interventions 4506 03:51:36,760 --> 03:51:39,800 that we might study. Next. 4507 03:51:41,800 --> 03:51:48,000 So, this -- next. This virus is an RNA virus. 4508 03:51:48,000 --> 03:51:50,720 It has and it's called the spike protein. 4509 03:51:50,720 --> 03:51:52,800 Which is how the virus enters the cells. 4510 03:51:52,800 --> 03:51:57,560 But it's, also, how vaccines confer immunity. 4511 03:51:57,560 --> 03:52:01,600 And then there are the nucleocapsid proteins presence 4512 03:52:01,600 --> 03:52:03,880 of immunity to which can address -- 4513 03:52:03,880 --> 03:52:06,280 can suggest that there was native infection, 4514 03:52:06,280 --> 03:52:09,760 and not just vaccine-induced immunity. Next. 4515 03:52:12,360 --> 03:52:16,920 As of a month ago, over half a billion people 4516 03:52:16,920 --> 03:52:19,880 were known to have been infected with this virus. 4517 03:52:19,880 --> 03:52:25,680 And, likely, there are many more unsuspected cases, 4518 03:52:25,680 --> 03:52:29,680 so that as much as one in 10 persons worldwide 4519 03:52:29,680 --> 03:52:33,200 have had this infection. Next slide. 4520 03:52:33,200 --> 03:52:36,800 And we know that over time the virus has evolved. 4521 03:52:36,800 --> 03:52:39,000 So, you have had the Delta surges, 4522 03:52:39,000 --> 03:52:41,400 recently the Omicron surge. 4523 03:52:41,400 --> 03:52:46,040 And, next, unfortunately, large parts of the world, 4524 03:52:46,040 --> 03:52:51,640 the areas in brown, remain very poorly vaccinated. 4525 03:52:51,640 --> 03:52:53,880 And, so, the virus is likely to spread 4526 03:52:53,880 --> 03:52:55,800 and evolve in these regions. 4527 03:52:55,800 --> 03:53:01,600 Which may lead to persistence of the pandemic. Next. 4528 03:53:01,600 --> 03:53:07,680 So, why worry about ADRD in the midst of this pandemic? 4529 03:53:07,680 --> 03:53:13,800 Next. Some of the early reasons for alarm, next, 4530 03:53:13,800 --> 03:53:19,040 were that we know SARS and MERS, which are similar coronaviruses, 4531 03:53:19,040 --> 03:53:22,000 could affect the brain in some patients. 4532 03:53:22,000 --> 03:53:25,360 We know that anosmia, which is characteristic of COVID-19, 4533 03:53:25,360 --> 03:53:28,360 is an early sign in some neurodegenerative diseases, 4534 03:53:28,360 --> 03:53:30,640 like Alzheimer's and Parkinson's. 4535 03:53:30,640 --> 03:53:33,520 And the last time we had a pandemic of this proportion, 4536 03:53:33,520 --> 03:53:37,200 there was delayed post-encephalitic parkinsonism. 4537 03:53:37,200 --> 03:53:39,640 Next. There was, also, alarm 4538 03:53:39,640 --> 03:53:43,920 because there was a suspicion of trans-synaptic transmission 4539 03:53:43,920 --> 03:53:48,320 from the olfactory mucosa into the brain, next, 4540 03:53:48,320 --> 03:53:51,800 as well as perhaps trans-endothelial are carried 4541 03:53:51,800 --> 03:53:57,400 by macrophages movement from the blood system into the brain. 4542 03:53:57,400 --> 03:54:01,600 Next. However, at autopsy, the virus, 4543 03:54:01,600 --> 03:54:04,480 or even evidence of past viral replication, 4544 03:54:04,480 --> 03:54:07,400 is rarely seen. Next. 4545 03:54:07,400 --> 03:54:10,320 And, so, there are a number of theories, 4546 03:54:10,320 --> 03:54:12,440 some of which you will hear about, 4547 03:54:12,440 --> 03:54:17,280 about how the virus may be having the unquestionable impact 4548 03:54:17,280 --> 03:54:20,840 on thinking, memory. 4549 03:54:20,840 --> 03:54:25,080 Some of it may be that the virus enters certain glial cells, 4550 03:54:25,080 --> 03:54:27,160 and other parts, through receptors, 4551 03:54:27,160 --> 03:54:30,000 such as the H2 receptor in urapalin. 4552 03:54:30,000 --> 03:54:32,280 There is endothelial damage, micro trauma 4553 03:54:32,280 --> 03:54:37,240 by the impact of both systemic as well as local inflammation, 4554 03:54:37,240 --> 03:54:40,880 as well as changes in neurotransmitters. 4555 03:54:40,880 --> 03:54:44,240 What is unquestionable is that there are symptoms. 4556 03:54:44,240 --> 03:54:48,880 Next. What we do not yet know, 4557 03:54:48,880 --> 03:54:51,800 because the virus has only been with us for two years, 4558 03:54:51,800 --> 03:54:56,560 is that are these mostly temporary. 4559 03:54:56,560 --> 03:55:00,240 Clearly, in some people, they appear to be persistent. 4560 03:55:00,240 --> 03:55:02,520 And might they be progressive? 4561 03:55:02,520 --> 03:55:06,080 And what is the biology around this? 4562 03:55:06,080 --> 03:55:08,600 Here, I do want to emphasize that the working group 4563 03:55:08,600 --> 03:55:12,240 recognized that ADRD is a broad umbrella. 4564 03:55:12,240 --> 03:55:16,800 We are not necessarily only wanting to focus on amyloid 4565 03:55:16,800 --> 03:55:18,480 and tau pathology, 4566 03:55:18,480 --> 03:55:21,480 nor suggesting we know enough to suggest that the virus, 4567 03:55:21,480 --> 03:55:25,520 in fact, increases the risk of traditional AD. 4568 03:55:25,520 --> 03:55:30,800 But ADRD does also include VCID. It includes all the conditions 4569 03:55:30,800 --> 03:55:33,200 that have been discussed over the last two days, 4570 03:55:33,200 --> 03:55:35,760 as well as immune-mediated cognitive decline, 4571 03:55:35,760 --> 03:55:38,080 sequelae of sexes and inflammation. 4572 03:55:38,080 --> 03:55:41,200 Here is an opportunity to study this area, 4573 03:55:41,200 --> 03:55:44,360 as well as other mechanisms like mitochondrial dysfunction. 4574 03:55:44,360 --> 03:55:49,600 Next. And, so, we need models. 4575 03:55:49,600 --> 03:55:51,600 And, unfortunately, we are just at the beginning 4576 03:55:51,600 --> 03:55:54,160 of developing cell and animal models. 4577 03:55:54,160 --> 03:55:55,760 And, also, we need to understand 4578 03:55:55,760 --> 03:55:58,520 their translational relevance to human disease. 4579 03:55:58,520 --> 03:56:01,080 Some of the models that have been developed include, 4580 03:56:01,080 --> 03:56:05,120 next, IPSC organoids and assembloids 4581 03:56:05,120 --> 03:56:07,440 that have neurons and glial cells, 4582 03:56:07,440 --> 03:56:11,680 vascular and perivascular cells susceptible to the virus, 4583 03:56:11,680 --> 03:56:16,600 next, zebrafish with H2 receptors, 4584 03:56:16,600 --> 03:56:19,920 next, where you can see the impact of the spike protein 4585 03:56:19,920 --> 03:56:24,320 in inducing immunological and inflammatory changes. 4586 03:56:24,320 --> 03:56:27,240 Next. Some mouse models that appear 4587 03:56:27,240 --> 03:56:30,440 to be susceptible to COVID-induced, 4588 03:56:30,440 --> 03:56:36,400 next, anosmia resulting in being unable to detect food 4589 03:56:36,400 --> 03:56:40,760 or partners of the opposite sex. How relevant are these models? 4590 03:56:40,760 --> 03:56:43,800 These are things we need to study in the translational way. 4591 03:56:43,800 --> 03:56:46,520 Next. 4592 03:56:46,520 --> 03:56:52,400 We need to query the data hidden in electronic health records. 4593 03:56:52,400 --> 03:56:56,320 We already have data suggesting that the risk of COVID 4594 03:56:56,320 --> 03:57:00,160 is doubled in persons with pre-existing dementia. 4595 03:57:00,160 --> 03:57:03,440 It's, also, clear that certain populations, 4596 03:57:03,440 --> 03:57:06,640 like African-Americans, are more vulnerable to COVID, 4597 03:57:06,640 --> 03:57:10,400 having three times the risk of Whites. Next. 4598 03:57:10,400 --> 03:57:12,680 Is it, also, true that these populations 4599 03:57:12,680 --> 03:57:16,120 are more vulnerable to ADRD type pathology 4600 03:57:16,120 --> 03:57:18,600 developing or accelerating after COVID? 4601 03:57:18,600 --> 03:57:21,800 And, if so, why? Next. 4602 03:57:21,800 --> 03:57:25,000 One suggestion was that, in the pandemic, 4603 03:57:25,000 --> 03:57:28,360 caregivers were already under stress, 4604 03:57:28,360 --> 03:57:29,840 persons living with dementia 4605 03:57:29,840 --> 03:57:32,480 were less able to follow precautions, 4606 03:57:32,480 --> 03:57:36,600 and may suffer from withdrawal of things like social support. 4607 03:57:36,600 --> 03:57:40,400 Next. So, was the higher risk entirely 4608 03:57:40,400 --> 03:57:43,000 due to behavioral and environmental factors? 4609 03:57:43,000 --> 03:57:45,360 Next. There is a suggestion 4610 03:57:45,360 --> 03:57:48,240 that there was some biological and genetic factors 4611 03:57:48,240 --> 03:57:52,200 as well that may underlie the higher susceptibility to COVID 4612 03:57:52,200 --> 03:57:56,880 in persons with dementia. In this study from Finland, 4613 03:57:56,880 --> 03:57:59,920 3,000 hospitalized now patient cases 4614 03:57:59,920 --> 03:58:03,360 were matched to controls in this Finland cohort. 4615 03:58:03,360 --> 03:58:07,360 And persons who had APLE 4 were more likely to have severe 4616 03:58:07,360 --> 03:58:09,880 COVID, to have micro hemorrhages, 4617 03:58:09,880 --> 03:58:13,080 and also to have post-COVID mental fatigue. 4618 03:58:13,080 --> 03:58:17,080 So, genetic studies may help with risk prediction, 4619 03:58:17,080 --> 03:58:19,080 as well as understanding the biology, 4620 03:58:19,080 --> 03:58:23,520 and perhaps finding intervention targets. Next. 4621 03:58:26,000 --> 03:58:27,760 In the GEN-COVID, 4622 03:58:27,760 --> 03:58:30,200 which is looking at the genetics of COVID, 4623 03:58:30,200 --> 03:58:34,760 some genes not previously strongly associated with AD, 4624 03:58:34,760 --> 03:58:39,400 like oligoadenylate synthetase 1, were identified. 4625 03:58:39,400 --> 03:58:41,120 And then, subsequently, it was found 4626 03:58:41,120 --> 03:58:43,520 that these may have a role in AD as well. 4627 03:58:43,520 --> 03:58:47,680 Next. For instance, the OAS1 gene 4628 03:58:47,680 --> 03:58:51,000 seems to determine whether microglia are more 4629 03:58:51,000 --> 03:58:53,720 in the interferon responsive subtype, 4630 03:58:53,720 --> 03:58:57,400 or the amyloid response of an amyloid removing subtype. 4631 03:58:57,400 --> 03:58:59,240 And if you have a genetic variation 4632 03:58:59,240 --> 03:59:02,000 that predisposes you to have more microglia 4633 03:59:02,000 --> 03:59:04,280 of the interferon responsive subtype, 4634 03:59:04,280 --> 03:59:07,160 the hypothesis goes that you may be more susceptible 4635 03:59:07,160 --> 03:59:09,200 to both AD and severe COVID. 4636 03:59:09,200 --> 03:59:12,400 Again, this needs to be validated in further studies. 4637 03:59:12,400 --> 03:59:16,080 But this is the preliminary data. Next slide. 4638 03:59:16,080 --> 03:59:18,240 So, what are the kinds of infrastructure 4639 03:59:18,240 --> 03:59:22,240 we wish to emphasize? Next. 4640 03:59:22,240 --> 03:59:27,800 We, next, want to recognize 4641 03:59:27,800 --> 03:59:32,720 that there is opportunity in the pandemic, 4642 03:59:32,720 --> 03:59:36,000 in that factors beyond biology, 4643 03:59:36,000 --> 03:59:39,240 factors such as national health policies, 4644 03:59:39,240 --> 03:59:42,000 and the effectiveness in controlling the pandemic, 4645 03:59:42,000 --> 03:59:45,800 may also have a role in whatever we see in terms of sequelae. 4646 03:59:45,800 --> 03:59:47,880 For instance, when the global burden of disease 4647 03:59:47,880 --> 03:59:50,240 looked at depression and anxiety, 4648 03:59:50,240 --> 03:59:53,560 not surprisingly, during the pandemic, it went up. 4649 03:59:53,560 --> 03:59:56,760 But it, also, went up more in countries 4650 03:59:56,760 --> 03:59:59,520 where the health policies and effectiveness 4651 03:59:59,520 --> 04:00:03,600 in controlling COVID was less. 4652 04:00:03,600 --> 04:00:07,840 And this is, again, understandable. Next. So -- 4653 04:00:07,840 --> 04:00:09,360 -Two minutes remaining. 4654 04:00:09,360 --> 04:00:12,000 -Next. We recognize that there are many factors, 4655 04:00:12,000 --> 04:00:14,720 such as the virus and variations in the virus, 4656 04:00:14,720 --> 04:00:19,560 next, as well as indirect factors like access 4657 04:00:19,560 --> 04:00:23,440 to physical activity and diet, next, 4658 04:00:23,440 --> 04:00:29,240 as well as, next, modifiers in the environment. 4659 04:00:29,240 --> 04:00:32,800 And, therefore, our recommendation, next, 4660 04:00:32,800 --> 04:00:36,360 emphasizes the need to carefully ascertain details 4661 04:00:36,360 --> 04:00:38,920 about the infection and treatment, 4662 04:00:38,920 --> 04:00:41,600 as well as the impact of policy interventions, 4663 04:00:41,600 --> 04:00:43,520 like paid family leave, 4664 04:00:43,520 --> 04:00:46,200 as well as the role of access to care, 4665 04:00:46,200 --> 04:00:49,240 and the possible benefit from innovative technologies 4666 04:00:49,240 --> 04:00:53,000 like telemedicine. Next. 4667 04:00:53,000 --> 04:00:58,240 We emphasize the need to use established clinical cohorts, 4668 04:00:58,240 --> 04:01:00,160 like the NIH, NINDSC 4669 04:01:00,160 --> 04:01:04,000 4R, the UK Biobank, which you'll hear about later, 4670 04:01:04,000 --> 04:01:06,320 as well as new longitudinal cohorts, 4671 04:01:06,320 --> 04:01:10,320 like the recovery effort, existing dementia cohorts, 4672 04:01:10,320 --> 04:01:12,560 like the ADRCs and NAC, 4673 04:01:12,560 --> 04:01:16,920 as well as the cohorts that were exposed to acute trials, 4674 04:01:16,920 --> 04:01:20,360 like monoclonals that might reduce the severity of COVID. 4675 04:01:20,360 --> 04:01:24,120 Next. And to record -- 4676 04:01:24,120 --> 04:01:28,480 to collect fluids and use novel imaging techniques, 4677 04:01:28,480 --> 04:01:33,440 next, harmonize the various measures of cognition 4678 04:01:33,440 --> 04:01:39,200 and other modalities, next, so that we can rapidly implement 4679 04:01:39,200 --> 04:01:41,760 in parallel candidate drug screening. 4680 04:01:41,760 --> 04:01:44,680 And with this natural history and biomarkers known, 4681 04:01:44,680 --> 04:01:47,600 go forward for treatment tracks. Next. 4682 04:01:47,600 --> 04:01:49,360 -Time. 4683 04:01:49,360 --> 04:01:53,720 -We will be looking at both population-based, 4684 04:01:53,720 --> 04:01:56,240 hospital-based, and other types of clinics, 4685 04:01:56,240 --> 04:02:02,320 next, novel methods that look at areas 4686 04:02:02,320 --> 04:02:04,680 that may be susceptible to MRI -- 4687 04:02:04,680 --> 04:02:07,880 to COVID, such as the locus coeruleus 4688 04:02:07,880 --> 04:02:10,600 and the olfactory lobes, next, 4689 04:02:10,600 --> 04:02:14,120 and emphasize longitudinal data collection. 4690 04:02:14,120 --> 04:02:17,280 Because there may be a delayed impact of the virus 4691 04:02:17,280 --> 04:02:23,400 that is only detectable with repeated assessment. Next. 4692 04:02:23,400 --> 04:02:27,320 So, I'll now hand over to my colleague, 4693 04:02:27,320 --> 04:02:28,760 Professor Avindra Nath, 4694 04:02:28,760 --> 04:02:31,560 to discuss the neuropathology of the virus. 4695 04:02:36,400 --> 04:02:40,160 -Thank you, Sudha, for the wonderful introduction. 4696 04:02:40,160 --> 04:02:44,880 And so I'm going to talk about the neuropathology. 4697 04:02:44,880 --> 04:02:49,800 And if you look at the various syndromes associated with COVID, 4698 04:02:49,800 --> 04:02:53,000 can be divided into three major categories. 4699 04:02:53,000 --> 04:02:54,480 One is during the acute phase 4700 04:02:54,480 --> 04:02:56,840 when the patient is admitted to the hospital. 4701 04:02:56,840 --> 04:02:59,680 At that time, there is a lot of end-organ damage, 4702 04:02:59,680 --> 04:03:01,160 and so there's no surprise 4703 04:03:01,160 --> 04:03:02,720 that the brain is going to get involved. 4704 04:03:02,720 --> 04:03:04,600 However, the brain can be directly involved 4705 04:03:04,600 --> 04:03:09,160 by vascular disease and very, very rarely, 4706 04:03:09,160 --> 04:03:13,120 are there any cases of true viral encephalitis. 4707 04:03:13,120 --> 04:03:14,600 Then you have the subacute phase 4708 04:03:14,600 --> 04:03:17,120 where these are largely post-viral syndromes, 4709 04:03:17,120 --> 04:03:18,800 but they're all inflammatory syndromes. 4710 04:03:18,800 --> 04:03:21,480 And you can see them with almost any kind of viral infection. 4711 04:03:21,480 --> 04:03:24,960 So they are acute disseminated encephalomyelitis, 4712 04:03:24,960 --> 04:03:28,120 necrotizing encephalopathy, limbic encephalitis. 4713 04:03:28,120 --> 04:03:35,480 So they are mediated by very specific types of immune cells. 4714 04:03:35,480 --> 04:03:37,640 And then there's a unique syndrome 4715 04:03:37,640 --> 04:03:39,800 associated with the virus in children 4716 04:03:39,800 --> 04:03:44,000 that is called multi-system inflammatory syndrome. 4717 04:03:44,000 --> 04:03:45,320 Well, we're going to spend a lot of time 4718 04:03:45,320 --> 04:03:48,800 talking about chronic manifestation, 4719 04:03:48,800 --> 04:03:50,800 which is long COVID. Next slide. 4720 04:03:53,000 --> 04:03:54,600 So just as Sudha said, 4721 04:03:54,600 --> 04:03:59,000 you know, the concern was, early in the pandemic, 4722 04:03:59,000 --> 04:04:01,520 that can the virus really enter the brain. 4723 04:04:01,520 --> 04:04:06,080 As you can see here, in the cribriform plate 4724 04:04:06,080 --> 04:04:07,920 is this very thin piece of bone 4725 04:04:07,920 --> 04:04:10,960 that's separating the brain from the nasal cavity, 4726 04:04:10,960 --> 04:04:13,480 and there are all these olfactory nerves 4727 04:04:13,480 --> 04:04:15,280 traversing this cribriform plate. 4728 04:04:15,280 --> 04:04:18,480 So the question is, can the virus really get in? 4729 04:04:18,480 --> 04:04:20,120 It turns out that the olfactory nerves 4730 04:04:20,120 --> 04:04:21,840 themselves never get infected, 4731 04:04:21,840 --> 04:04:23,880 and what gets infected are really the sustentacular cells, 4732 04:04:23,880 --> 04:04:29,200 which are the support cells. So next slide. 4733 04:04:29,200 --> 04:04:33,200 And so if you actually look for virus in these regions, 4734 04:04:33,200 --> 04:04:34,800 what you find is that the olfactory -- 4735 04:04:34,800 --> 04:04:37,440 because it has a lot of virus, okay? 4736 04:04:37,440 --> 04:04:39,640 And the olfactory bulb and the tubercule, 4737 04:04:39,640 --> 04:04:42,600 very rarely do you find any virus at all. 4738 04:04:42,600 --> 04:04:44,800 So it really stays in the mucosa. 4739 04:04:44,800 --> 04:04:47,080 And as you can see on the right-hand side, 4740 04:04:47,080 --> 04:04:49,720 these small viral particles, 4741 04:04:49,720 --> 04:04:51,800 these round structures are viral particles here 4742 04:04:51,800 --> 04:04:54,240 that causes a huge amount of virus, 4743 04:04:54,240 --> 04:04:56,560 and because of that, that's where it stays. 4744 04:04:56,560 --> 04:05:01,000 Next slide, please. So there are other groups 4745 04:05:01,000 --> 04:05:04,400 that have detected small amounts of virus in the brain, 4746 04:05:04,400 --> 04:05:06,640 but you find it very infrequently, 4747 04:05:06,640 --> 04:05:10,880 and when you do find it, you don't find any inflammation 4748 04:05:10,880 --> 04:05:13,080 around the areas when they detect them, 4749 04:05:13,080 --> 04:05:16,200 so we don't think that is of much pathogenic significance. 4750 04:05:16,200 --> 04:05:17,840 We, and several other groups, 4751 04:05:17,840 --> 04:05:21,680 have failed to detect any virus in the brain 4752 04:05:21,680 --> 04:05:25,040 using a wide variety of very sensitive techniques. 4753 04:05:25,040 --> 04:05:29,600 Next slide, please. And what I want to emphasize 4754 04:05:29,600 --> 04:05:33,320 is that the major pathology really is vascular injury, 4755 04:05:33,320 --> 04:05:35,800 and I think that has a lot of implications 4756 04:05:35,800 --> 04:05:39,400 for microvascular disease and Alzheimer's-like pathology. 4757 04:05:39,400 --> 04:05:43,520 So next slide, please. And so the vascular pathology 4758 04:05:43,520 --> 04:05:45,280 can present in many different ways. 4759 04:05:45,280 --> 04:05:47,720 You can get frank infarcts. You can get bilateral infarcts. 4760 04:05:47,720 --> 04:05:50,360 You can get brain and other organ systems 4761 04:05:50,360 --> 04:05:52,400 where blood vessels can get occluded. 4762 04:05:52,400 --> 04:05:56,800 And then there are individuals who can get microhemorrhages 4763 04:05:56,800 --> 04:06:00,960 and other individuals who can occlude the venous system, 4764 04:06:00,960 --> 04:06:04,200 and you can get cerebral venous thromboses as well. 4765 04:06:04,200 --> 04:06:07,400 Interestingly, the study here looked at microhemorrhages, 4766 04:06:07,400 --> 04:06:09,520 and what they found was that those individuals 4767 04:06:09,520 --> 04:06:12,840 who are APOE positive are at greater risk 4768 04:06:12,840 --> 04:06:14,200 of developing hemorrhages, 4769 04:06:14,200 --> 04:06:15,960 looking at different parts of the brain, 4770 04:06:15,960 --> 04:06:17,440 as you can see here. 4771 04:06:17,440 --> 04:06:20,000 And there's more severe hemorrhages, 4772 04:06:20,000 --> 04:06:24,640 and more areas are involved. Next slide, please. 4773 04:06:26,680 --> 04:06:30,800 So besides frank hemorrhages, you can also see -- 4774 04:06:30,800 --> 04:06:32,040 without the presence of hemorrhage, 4775 04:06:32,040 --> 04:06:36,880 you can still see microvascular pathology. 4776 04:06:36,880 --> 04:06:40,600 And here, what we did is, we did postmortem MRI scans, 4777 04:06:40,600 --> 04:06:42,880 and these are very high-resolution scans 4778 04:06:42,880 --> 04:06:44,360 using 11 Tesla scanner. 4779 04:06:44,360 --> 04:06:47,280 And you can see, these blood vessels here, 4780 04:06:47,280 --> 04:06:48,680 they look abnormal. 4781 04:06:48,680 --> 04:06:51,600 And when we stain them for fibrinogen, 4782 04:06:51,600 --> 04:06:53,000 which is a protein that should be present 4783 04:06:53,000 --> 04:06:55,200 only in the blood and not outside, 4784 04:06:55,200 --> 04:06:57,400 you actually see the leakage of fibrinogen. 4785 04:06:57,400 --> 04:07:00,400 So these blood vessels are really very leaky. 4786 04:07:00,400 --> 04:07:03,960 So they aren't leaking RBCs, but they're leaking proteins. 4787 04:07:03,960 --> 04:07:05,200 Here in the olfactory bulb, 4788 04:07:05,200 --> 04:07:07,280 you find the exact same thing, too. 4789 04:07:07,280 --> 04:07:09,800 There was a lot of fibrinogen there. 4790 04:07:09,800 --> 04:07:12,280 But within the blood vessel itself, 4791 04:07:12,280 --> 04:07:14,680 you can see aggregation of platelets. 4792 04:07:14,680 --> 04:07:17,520 So this is another form of microvascular disease here now. 4793 04:07:17,520 --> 04:07:18,800 Instead of them leaking, 4794 04:07:18,800 --> 04:07:20,520 the endothelial cells are activated 4795 04:07:20,520 --> 04:07:24,200 to whereby the platelets stick to them, and they get activated. 4796 04:07:24,200 --> 04:07:26,920 And you can see occlusion of the small blood vessels 4797 04:07:26,920 --> 04:07:29,200 here as well from these platelets. 4798 04:07:29,200 --> 04:07:33,800 And what we find is that you see it more often in the hindbrain, 4799 04:07:33,800 --> 04:07:37,800 which is the brain stem and the cerebellum, 4800 04:07:37,800 --> 04:07:40,120 and we looked at all kinds of controls. 4801 04:07:40,120 --> 04:07:42,000 You don't really see them. You only find them -- 4802 04:07:42,000 --> 04:07:44,800 it's quite specific for these COVID patients. 4803 04:07:44,800 --> 04:07:46,400 Next, please. 4804 04:07:48,560 --> 04:07:51,200 There are some individuals who developed tinnitus, 4805 04:07:51,200 --> 04:07:54,080 acute onset of ringing of ears. 4806 04:07:54,080 --> 04:07:56,720 It's associated with loss of hearing. 4807 04:07:56,720 --> 04:07:59,200 And next slide, please. 4808 04:07:59,200 --> 04:08:03,760 And others that would develop acute onset of vertigo. 4809 04:08:03,760 --> 04:08:06,320 We think these are actually vascular phenomenon, 4810 04:08:06,320 --> 04:08:08,680 and that is possible that the small blood vessels 4811 04:08:08,680 --> 04:08:10,880 supplying the inner ear get occluded 4812 04:08:10,880 --> 04:08:14,400 because it's fairly sudden onset in these individuals. 4813 04:08:14,400 --> 04:08:17,280 Next slide, please. Okay. 4814 04:08:17,280 --> 04:08:22,520 Then there's the subacute phase. Next slide. 4815 04:08:22,520 --> 04:08:23,960 And as I said, you know, 4816 04:08:23,960 --> 04:08:26,680 you can get acute disseminated encephalomyelitis 4817 04:08:26,680 --> 04:08:28,200 as shown over here. 4818 04:08:28,200 --> 04:08:30,800 This is largely a T-cell-mediated phenomenon. 4819 04:08:30,800 --> 04:08:32,920 Some get necrotizing encephalopathy, 4820 04:08:32,920 --> 04:08:34,960 which is largely a cytokine-mediated phenomenon, 4821 04:08:34,960 --> 04:08:36,880 so those things are very important to recognize 4822 04:08:36,880 --> 04:08:38,760 because they're treatable very differently, 4823 04:08:38,760 --> 04:08:42,000 and the long-term implications are also different. 4824 04:08:42,000 --> 04:08:45,320 Next slide, please. And then, in children, 4825 04:08:45,320 --> 04:08:47,400 you can get this multi-inflammatory syndrome. 4826 04:08:47,400 --> 04:08:49,200 As you can see on the screen, in the corpus callosum, 4827 04:08:49,200 --> 04:08:51,480 there's a high-signal intensity lesion here 4828 04:08:51,480 --> 04:08:53,400 and loss of inflammatory markers. 4829 04:08:53,400 --> 04:08:55,280 So the long-term consequences of this 4830 04:08:55,280 --> 04:08:58,800 are not fully understood. Next slide, please. 4831 04:09:01,080 --> 04:09:04,680 Then, as I showed you earlier, 4832 04:09:04,680 --> 04:09:06,160 you know, there's leakage of proteins, 4833 04:09:06,160 --> 04:09:07,800 but if you look for the cellular infiltrates, 4834 04:09:07,800 --> 04:09:09,240 you find they're largely macrophages. 4835 04:09:09,240 --> 04:09:11,560 I think they're coming in there to clean out 4836 04:09:11,560 --> 04:09:14,200 all the proteins that are leaking, 4837 04:09:14,200 --> 04:09:18,000 but once the macrophages enter there, they don't leave. 4838 04:09:18,000 --> 04:09:21,960 So they will cause a lot of damage to surrounding tissues. 4839 04:09:21,960 --> 04:09:23,680 You hardly ever find any T cells, 4840 04:09:23,680 --> 04:09:26,000 and that tells you that, if it was a viral encephalitis, 4841 04:09:26,000 --> 04:09:27,240 you should see a lot of T cells. 4842 04:09:27,240 --> 04:09:29,480 You actually don't see any. No. 4843 04:09:29,480 --> 04:09:31,680 And you got astrocyte activation here, too. 4844 04:09:31,680 --> 04:09:37,000 Yeah, next slide. You can get peripheral nerve involvement. 4845 04:09:37,000 --> 04:09:39,640 So you can see the cranial nerves 4846 04:09:39,640 --> 04:09:42,960 as well as the roots coming out 4847 04:09:42,960 --> 04:09:45,680 can get inflamed and involved as well. 4848 04:09:45,680 --> 04:09:49,800 So you can get widespread peripheral nerve involvement. 4849 04:09:49,800 --> 04:09:52,840 Next. 4850 04:09:52,840 --> 04:09:56,360 And in some patients, you can also get myositis. 4851 04:09:56,360 --> 04:09:58,200 As I said, inflammatory myositis, 4852 04:09:58,200 --> 04:10:02,920 that responds to treatment with high-dose corticosteroids. 4853 04:10:02,920 --> 04:10:05,000 Next slide, please. 4854 04:10:05,000 --> 04:10:07,560 -Two minutes remaining. 4855 04:10:07,560 --> 04:10:10,800 -Next slide. 4856 04:10:10,800 --> 04:10:15,600 Well, what is important is that most patients, 4857 04:10:15,600 --> 04:10:19,400 they will recover early on for about three months or so. 4858 04:10:19,400 --> 04:10:21,320 If they don't recover by three months, 4859 04:10:21,320 --> 04:10:23,480 most of the symptoms start to persist, 4860 04:10:23,480 --> 04:10:27,360 and you see it more often in women as compared to men. 4861 04:10:27,360 --> 04:10:28,720 That again suggests to you 4862 04:10:28,720 --> 04:10:30,240 that it's an immune-mediated phenomenon, 4863 04:10:30,240 --> 04:10:33,400 most likely. Next slide. 4864 04:10:33,400 --> 04:10:36,600 So there are these individuals who, as I showed you, 4865 04:10:36,600 --> 04:10:38,480 they have severe symptoms initially. 4866 04:10:38,480 --> 04:10:41,200 They gradually got better, but not completely. 4867 04:10:41,200 --> 04:10:43,320 Then there are other individuals with mild symptoms, 4868 04:10:43,320 --> 04:10:46,120 they get better, but after a certain latent period, 4869 04:10:46,120 --> 04:10:47,800 they then get new symptoms again. 4870 04:10:47,800 --> 04:10:50,360 Okay. Next slide. 4871 04:10:50,360 --> 04:10:52,600 And we looked at a cohort of these individuals. 4872 04:10:52,600 --> 04:10:54,920 Almost all of them have cognitive abnormalities 4873 04:10:54,920 --> 04:10:56,320 as well as fatigue 4874 04:10:56,320 --> 04:10:59,120 and then a whole host of neurological symptoms 4875 04:10:59,120 --> 04:11:03,600 that are to a lesser degree. Next slide. 4876 04:11:03,600 --> 04:11:07,960 And so you can divide these patients into four groups, 4877 04:11:07,960 --> 04:11:11,640 some that have largely cognitive and mood and sleep disorders, 4878 04:11:11,640 --> 04:11:15,600 and I think that's the category that you're more interested in, 4879 04:11:15,600 --> 04:11:18,240 but there are other types of long COVID syndromes 4880 04:11:18,240 --> 04:11:20,360 that can present in these individuals. 4881 04:11:20,360 --> 04:11:22,720 Next slide. 4882 04:11:22,720 --> 04:11:25,680 And PET scan shows that these individuals 4883 04:11:25,680 --> 04:11:29,320 have decreased uptake of glucose in a more symmetric manner 4884 04:11:29,320 --> 04:11:30,600 involving the cortex. 4885 04:11:30,600 --> 04:11:32,760 So the cortex is diffusely involved 4886 04:11:32,760 --> 04:11:35,040 in these patients in the subacute group. 4887 04:11:35,040 --> 04:11:38,080 Next slide. 4888 04:11:38,080 --> 04:11:40,960 And this very recent study from the UK 4889 04:11:40,960 --> 04:11:45,480 shows that there is also -- they looked at this cohort 4890 04:11:45,480 --> 04:11:48,360 before and after development of COVID, 4891 04:11:48,360 --> 04:11:49,880 and it was a unique cohort, 4892 04:11:49,880 --> 04:11:52,080 that the total intracranial volume is decreased. 4893 04:11:52,080 --> 04:11:54,120 There is hippocampal -- 4894 04:11:54,120 --> 04:12:00,360 the gyrus is actually decreased and preferentially 4895 04:12:00,360 --> 04:12:05,680 and is associated with impairment of cognition as well. 4896 04:12:05,680 --> 04:12:07,960 So I think this is actually quite concerning, 4897 04:12:07,960 --> 04:12:10,040 and long-term follow-up will reveal what's happening. 4898 04:12:10,040 --> 04:12:12,200 Next slide, please. 4899 04:12:12,200 --> 04:12:13,520 -Time. 4900 04:12:13,520 --> 04:12:17,920 -Okay. Next slide. I'll just skip this one. 4901 04:12:17,920 --> 04:12:21,160 -And eventually, you can actually see neuronal loss here, 4902 04:12:21,160 --> 04:12:22,520 and we've shown that in the brainstem. 4903 04:12:22,520 --> 04:12:25,200 Note when you get activated microglia, 4904 04:12:25,200 --> 04:12:29,120 you can see loss over here. Next slide. 4905 04:12:29,120 --> 04:12:30,600 So, in conclusion, 4906 04:12:30,600 --> 04:12:33,200 direct invasion of the brain by SARS is rare, 4907 04:12:33,200 --> 04:12:34,800 and neuroimmune dysfunction, I think, 4908 04:12:34,800 --> 04:12:37,640 is by activation of innate immune responses, 4909 04:12:37,640 --> 04:12:40,480 and endothelial damage is the primary 4910 04:12:40,480 --> 04:12:42,400 pathophysiological process in Nero-COVID. 4911 04:12:42,400 --> 04:12:44,680 Next slide. 4912 04:12:44,680 --> 04:12:48,080 And these are our acknowledgements. 4913 04:12:48,080 --> 04:12:49,640 I'd like to thank each other people 4914 04:12:49,640 --> 04:12:52,480 who helped us with obtaining the tissues. 4915 04:12:52,480 --> 04:12:55,600 Serena and I ordered a review on this quite recently. 4916 04:12:55,600 --> 04:12:57,600 And these are the people in my lab who did all the work. 4917 04:12:57,600 --> 04:12:59,800 So I'll stop here. Thanks. 4918 04:13:08,320 --> 04:13:11,960 -Yes, Professor Erausquin. 4919 04:13:11,960 --> 04:13:14,400 -Thank you very much. 4920 04:13:14,400 --> 04:13:18,280 I'll get straight into it in the interest of time. 4921 04:13:18,280 --> 04:13:21,280 My run is to cover the clinical side 4922 04:13:21,280 --> 04:13:26,000 of the neurocognitive dysfunction after COVID-19. 4923 04:13:26,000 --> 04:13:28,360 Next slide, please. I don't have any disclosures. 4924 04:13:28,360 --> 04:13:31,080 Next slide, please. 4925 04:13:31,080 --> 04:13:34,240 And this has been a topic of concern 4926 04:13:34,240 --> 04:13:35,880 right from the beginning of the pandemic. 4927 04:13:35,880 --> 04:13:40,200 The publications about cognitive impairment in initial case 4928 04:13:40,200 --> 04:13:43,920 reports began in the immediate months 4929 04:13:43,920 --> 04:13:47,800 after the onset of the spread of the virus 4930 04:13:47,800 --> 04:13:52,040 and have continued to increase over the past 18 or 20 months. 4931 04:13:52,040 --> 04:13:54,760 What's more remarkable is that, from very early on, 4932 04:13:54,760 --> 04:13:57,600 the public eye also caught interest 4933 04:13:57,600 --> 04:13:59,800 in this particular phenomenon, 4934 04:13:59,800 --> 04:14:02,600 those initially described by patients, 4935 04:14:02,600 --> 04:14:07,480 by sufferers, as brain fog. Next slide, please. 4936 04:14:07,480 --> 04:14:10,800 The source of data have become increasingly sophisticated. 4937 04:14:10,800 --> 04:14:12,920 Initially, where I also mentioned case reports, 4938 04:14:12,920 --> 04:14:17,360 then more protracted, 4939 04:14:17,360 --> 04:14:20,240 more extended case series began to appear 4940 04:14:20,240 --> 04:14:23,080 involving primarily hospitalized patients 4941 04:14:23,080 --> 04:14:26,520 during or immediately after the acute phase of the illness, 4942 04:14:26,520 --> 04:14:30,240 and those follow-up appointments in clinics 4943 04:14:30,240 --> 04:14:35,240 describing persistent symptoms, as Dr. Nath already mentioned. 4944 04:14:35,240 --> 04:14:39,680 But better quality data perhaps and more relevant 4945 04:14:39,680 --> 04:14:43,440 from the point of view of the neurological importance 4946 04:14:43,440 --> 04:14:45,280 of this particular phenomenon 4947 04:14:45,280 --> 04:14:50,400 began to appear in surveys of patients 4948 04:14:50,400 --> 04:14:54,360 who were well characterized and being followed as part of 4949 04:14:54,360 --> 04:14:55,720 longitudinal cohorts, 4950 04:14:55,720 --> 04:14:58,080 such as the ones that Dr. Seshadri mentioned, 4951 04:14:58,080 --> 04:15:02,040 including Nath the framing of her study 4952 04:15:02,040 --> 04:15:04,280 or the San Antonio Mexican-American 4953 04:15:04,280 --> 04:15:07,240 pharmacy studies, which had -- 4954 04:15:07,240 --> 04:15:09,480 all the individuals who had been well characterized 4955 04:15:09,480 --> 04:15:11,840 and followed for a protracted period of time. 4956 04:15:11,840 --> 04:15:13,440 The biggest disadvantage of those cohorts 4957 04:15:13,440 --> 04:15:15,720 is that the relative number of affected individuals 4958 04:15:15,720 --> 04:15:18,800 was small and persists rather small. 4959 04:15:18,800 --> 04:15:22,000 So the better quality data are beginning to emerge 4960 04:15:22,000 --> 04:15:29,280 from new cohorts developed from population-based databases 4961 04:15:29,280 --> 04:15:32,160 or registries and include all individuals 4962 04:15:32,160 --> 04:15:35,360 who have been tested for COVID 4963 04:15:35,360 --> 04:15:36,800 during the course of the pandemic, 4964 04:15:36,800 --> 04:15:39,200 whether they came back positive or negative, 4965 04:15:39,200 --> 04:15:42,600 and that will be where I would focus more of my comments. 4966 04:15:42,600 --> 04:15:45,040 Next slide, please. 4967 04:15:45,040 --> 04:15:48,000 For instance, again, as Dr. Nath already mentioned, 4968 04:15:48,000 --> 04:15:51,160 there are good quality data from separate port of patients. 4969 04:15:51,160 --> 04:15:53,880 This is coming primarily from the UK biobank 4970 04:15:53,880 --> 04:15:56,920 that Dr. Seshadri mentioned, 4971 04:15:56,920 --> 04:15:59,120 pointing to the fact on the left top panel 4972 04:15:59,120 --> 04:16:03,520 that persisting symptoms are quite sustained. 4973 04:16:03,520 --> 04:16:07,200 Once they're present, after the few initial weeks 4974 04:16:07,200 --> 04:16:12,320 of the recording of the illness, they don't seem to go away. 4975 04:16:12,320 --> 04:16:14,720 More notably, the bulk of those symptoms 4976 04:16:14,720 --> 04:16:19,240 and the ones with highest probability, 4977 04:16:19,240 --> 04:16:22,360 they are on the bottom left panel -- 4978 04:16:22,360 --> 04:16:27,520 brain fog, memory issues, and difficulties with language. 4979 04:16:27,520 --> 04:16:32,920 But if you disclose a bit more on the top right panel, 4980 04:16:32,920 --> 04:16:36,760 you find that include primarily short-term memory loss 4981 04:16:36,760 --> 04:16:40,480 and word-finding difficulties. What's most remarkable is that, 4982 04:16:40,480 --> 04:16:44,800 if you consider the presence of the symptoms 4983 04:16:44,800 --> 04:16:50,520 on average across age groups, they seem to be, you know, 4984 04:16:50,520 --> 04:16:56,400 more or less the same across different strata of aging, 4985 04:16:56,400 --> 04:16:59,120 but when you disclose that in greater detail, 4986 04:16:59,120 --> 04:17:01,720 it turns out that younger individuals 4987 04:17:01,720 --> 04:17:03,400 have more much prominent problems 4988 04:17:03,400 --> 04:17:07,600 with attention, concentration, and executive dysfunction, 4989 04:17:07,600 --> 04:17:11,520 as opposed to true fewer memory problems 4990 04:17:11,520 --> 04:17:14,080 that appear to be much more prevalent 4991 04:17:14,080 --> 04:17:16,320 and severe in other individuals. 4992 04:17:16,320 --> 04:17:17,920 Next slide, please. 4993 04:17:20,200 --> 04:17:25,400 In the largest US-based study that was published 4994 04:17:25,400 --> 04:17:30,400 by Biden's administration recently, 4995 04:17:30,400 --> 04:17:33,400 they found that the neurocognitive decline 4996 04:17:33,400 --> 04:17:36,800 was actually two times more common in individuals 4997 04:17:36,800 --> 04:17:38,160 who had suffered COVID 4998 04:17:38,160 --> 04:17:41,640 and recovered within a relatively short time, 4999 04:17:41,640 --> 04:17:45,000 30 days after recovery than in historical controls, 5000 04:17:45,000 --> 04:17:46,480 when they looked at a very large sample 5001 04:17:46,480 --> 04:17:50,320 of close to 6 million people or contemporaneous, 5002 04:17:50,320 --> 04:17:52,360 so having controls that did not have 5003 04:17:52,360 --> 04:17:55,480 the disease in equal large number. 5004 04:17:55,480 --> 04:17:59,800 So this is quite clearly a unique phenomenon 5005 04:17:59,800 --> 04:18:04,080 to recovery from COVID. Next slide, please. 5006 04:18:04,080 --> 04:18:05,800 What's most important is that it's not 5007 04:18:05,800 --> 04:18:10,440 just when you compare the individuals that recover 5008 04:18:10,440 --> 04:18:12,600 from COVID to the general population, 5009 04:18:12,600 --> 04:18:15,680 but also if you compare them with individuals 5010 04:18:15,680 --> 04:18:17,720 who recovered from other, 5011 04:18:17,720 --> 04:18:20,520 similar respiratory flu-like syndromes. 5012 04:18:20,520 --> 04:18:22,160 And in this particular case, 5013 04:18:22,160 --> 04:18:24,560 the comparison was made to influenza. 5014 04:18:24,560 --> 04:18:29,400 And you can see that, as far as six months after recovery 5015 04:18:29,400 --> 04:18:32,760 from an acute respiratory severe illness, 5016 04:18:32,760 --> 04:18:36,320 flu-like illness, if the illness was COVID, 5017 04:18:36,320 --> 04:18:38,320 the likelihood of cognitive impairment 5018 04:18:38,320 --> 04:18:40,600 is almost two-fold 5019 04:18:40,600 --> 04:18:45,640 that of the patients that recovered from the regular flu. 5020 04:18:45,640 --> 04:18:49,000 The pattern of symptoms is actually similar, too. 5021 04:18:49,000 --> 04:18:52,080 Again, to what Dr. Nath mentioned, quite broad. 5022 04:18:52,080 --> 04:18:56,840 It includes things such as fatigue, muscle pain, 5023 04:18:56,840 --> 04:18:59,280 other forms of bodily pains, 5024 04:18:59,280 --> 04:19:00,720 occasionally anxiety and depression, 5025 04:19:00,720 --> 04:19:03,080 but more prominently, cognitive impairment. 5026 04:19:03,080 --> 04:19:04,680 Next slide, please. 5027 04:19:06,920 --> 04:19:09,040 The predictors of this COVID impairment 5028 04:19:09,040 --> 04:19:11,440 that appears to be quite peculiar 5029 04:19:11,440 --> 04:19:17,600 to recovery from SARS-CoV-2 or to the infection of COVID 5030 04:19:17,600 --> 04:19:20,680 are still open to question. 5031 04:19:20,680 --> 04:19:22,120 I'm going to show you two studies 5032 04:19:22,120 --> 04:19:23,560 from different sources of data 5033 04:19:23,560 --> 04:19:26,200 that lead to somewhat different conclusions, 5034 04:19:26,200 --> 04:19:29,600 and I will go back to this point a little bit later. 5035 04:19:29,600 --> 04:19:30,880 On the bottom two panels, 5036 04:19:30,880 --> 04:19:33,600 what you see is data from the UK biobank. 5037 04:19:33,600 --> 04:19:40,200 So these are retrospective data on patients across the board 5038 04:19:40,200 --> 04:19:43,360 who had suffered COVID and most of whom were hospitalized, 5039 04:19:43,360 --> 04:19:46,120 but as you will see in a moment, not all of them. 5040 04:19:46,120 --> 04:19:47,800 It's a very large sample. 5041 04:19:47,800 --> 04:19:51,440 And on the left panel, what you see is the prevalence 5042 04:19:51,440 --> 04:19:54,520 of what they called dementia-like symptoms, 5043 04:19:54,520 --> 04:19:59,000 meaning prominent impairment in several cognitive domains, 5044 04:19:59,000 --> 04:20:03,040 including memory, language, and executive function. 5045 04:20:03,040 --> 04:20:08,200 And this was compared to other respiratory tract infections, 5046 04:20:08,200 --> 04:20:09,480 patients who had recovered 5047 04:20:09,480 --> 04:20:10,960 from other respiratory tract infections. 5048 04:20:10,960 --> 04:20:13,200 You see again that the likelihood of developing 5049 04:20:13,200 --> 04:20:16,400 these chronic symptoms following COVID is almost two-fold. 5050 04:20:16,400 --> 04:20:18,840 And this was much more prominent 5051 04:20:18,840 --> 04:20:22,280 in the post-hospitalized patients who had encephalitis, 5052 04:20:22,280 --> 04:20:23,960 and that's the red line here, 5053 04:20:23,960 --> 04:20:25,600 compared to the dotted line there, 5054 04:20:25,600 --> 04:20:29,200 which are hospitalized patients without encephalitis, 5055 04:20:29,200 --> 04:20:31,600 or inpatients who were not hospitalized 5056 04:20:31,600 --> 04:20:36,640 the length here that did not have -- 5057 04:20:36,640 --> 04:20:39,800 compared to those that did not have the respiratory infection 5058 04:20:39,800 --> 04:20:41,920 in the bottom dotted line. 5059 04:20:41,920 --> 04:20:46,960 So the bottom line is, in the UK biobank data samples, 5060 04:20:46,960 --> 04:20:50,000 severity of the disease, particularly having encephalitis 5061 04:20:50,000 --> 04:20:54,920 or being hospitalized, resulted in much more likelihood 5062 04:20:54,920 --> 04:20:56,840 of having dementia-like symptoms. 5063 04:20:56,840 --> 04:20:58,280 The top part, on the other hand, 5064 04:20:58,280 --> 04:21:00,600 is the community-based sample for Amerindians 5065 04:21:00,600 --> 04:21:03,720 from Northern Argentina in the Andes Mountains 5066 04:21:03,720 --> 04:21:07,840 that shows that mechanical ventilation, ICU admission, 5067 04:21:07,840 --> 04:21:11,200 or oxygen dependency during the acute phase of the illness 5068 04:21:11,200 --> 04:21:15,960 did not predict a positive outcome, 5069 04:21:15,960 --> 04:21:18,800 and on the other hand, the presence of persistent 5070 04:21:18,800 --> 04:21:22,440 anosmia several months after the recovery, did. 5071 04:21:22,440 --> 04:21:25,120 Next slide, please. 5072 04:21:25,120 --> 04:21:27,600 -Two minutes remaining. 5073 04:21:27,600 --> 04:21:31,160 -What this translates to is to a very large increase 5074 04:21:31,160 --> 04:21:34,000 potentially in cases of cognitive impairment 5075 04:21:34,000 --> 04:21:36,080 for the US population as a whole. 5076 04:21:36,080 --> 04:21:43,680 If you consider that as many as 3 and 1/2 million cases 5077 04:21:43,680 --> 04:21:45,320 of new cognitive impairment 5078 04:21:45,320 --> 04:21:49,200 will be present in the next two or three years, you know, 5079 04:21:49,200 --> 04:21:53,840 assuming that this data remain as they are now, 5080 04:21:53,840 --> 04:21:55,640 that would represent a more than two-fold 5081 04:21:55,640 --> 04:21:59,720 increase in the number of cases and a large increasing burden. 5082 04:21:59,720 --> 04:22:02,880 Next slide, please. What's most concerning 5083 04:22:02,880 --> 04:22:06,440 is that this may not be evenly distributed 5084 04:22:06,440 --> 04:22:08,960 among different subpopulations within the United States. 5085 04:22:08,960 --> 04:22:12,880 Indeed, we don't know if rate of infection 5086 04:22:12,880 --> 04:22:15,600 or rate of hospitalization will result, as I mentioned, 5087 04:22:15,600 --> 04:22:18,000 in higher increases in cognitive decline. 5088 04:22:18,000 --> 04:22:21,880 But we do know that under-represented populations 5089 04:22:21,880 --> 04:22:25,320 are at much higher risk of having severe disease 5090 04:22:25,320 --> 04:22:27,720 and having hospitalization. 5091 04:22:27,720 --> 04:22:30,680 So there is a chance that they may also sustain 5092 04:22:30,680 --> 04:22:32,240 a much larger burden of disease. 5093 04:22:32,240 --> 04:22:34,320 Next slide. 5094 04:22:34,320 --> 04:22:36,040 This is particularly important because, 5095 04:22:36,040 --> 04:22:40,680 as I mentioned, in the Amerindian population 5096 04:22:40,680 --> 04:22:44,560 that we started with the registry, 5097 04:22:44,560 --> 04:22:51,040 the severity and frequency of cognitive impairment 5098 04:22:51,040 --> 04:22:55,000 reaches about 40% of the sample. Next slide. 5099 04:22:55,000 --> 04:22:58,920 So, as next steps, I think we need to concentrate 5100 04:22:58,920 --> 04:23:01,080 on understanding what are the variations 5101 04:23:01,080 --> 04:23:03,160 in the clinical phenotype of neurocognitive amoralities 5102 04:23:03,160 --> 04:23:07,400 following COVID that are just now beginning to be described, 5103 04:23:07,400 --> 04:23:09,480 and particularly the relationships of clinical 5104 04:23:09,480 --> 04:23:11,360 manifestations with underlying biology 5105 04:23:11,360 --> 04:23:14,680 as Dr. Seshadri described in great detail. 5106 04:23:14,680 --> 04:23:16,560 I think it's of the highest importance 5107 04:23:16,560 --> 04:23:20,240 to establish and detail a course of this cognitive impairment 5108 04:23:20,240 --> 04:23:22,800 as well as histology resiliency cultures 5109 04:23:22,800 --> 04:23:26,480 and possible targets for myofibril risk, 5110 04:23:26,480 --> 04:23:28,240 and we need to understand the role of variations 5111 04:23:28,240 --> 04:23:30,040 in the viral genome as well as the interactions 5112 04:23:30,040 --> 04:23:33,800 between the various variants and host risk/resilience 5113 04:23:33,800 --> 04:23:37,480 factors affecting this cognitive decline. 5114 04:23:37,480 --> 04:23:39,080 Environmental factors, 5115 04:23:39,080 --> 04:23:41,440 including social structure and systemic inequalities, 5116 04:23:41,440 --> 04:23:42,840 appear to have profound effects 5117 04:23:42,840 --> 04:23:45,320 in the morbidity and mortality of COVID, 5118 04:23:45,320 --> 04:23:47,040 and it is really urgent to understand 5119 04:23:47,040 --> 04:23:51,200 if they will also affect the long-term cognitive outcomes. 5120 04:23:51,200 --> 04:23:52,800 Thank you very much. 5121 04:23:58,080 --> 04:24:01,800 -So thank you very much for inviting me to give this talk, 5122 04:24:01,800 --> 04:24:06,440 and as I'm following a couple of really fantastic presentations 5123 04:24:06,440 --> 04:24:09,160 that really, I think, set this talk up very nicely. 5124 04:24:09,160 --> 04:24:12,080 So the focus of this talk is really looking at biomarkers 5125 04:24:12,080 --> 04:24:15,520 of COVID-19 and thinking about what they may be able 5126 04:24:15,520 --> 04:24:18,880 to teach us about potential clinical trial targets for AD 5127 04:24:18,880 --> 04:24:23,400 and ADRD-related to COVID. Next slide, please. 5128 04:24:23,400 --> 04:24:27,040 So I have no disclosures. Next slide. 5129 04:24:27,040 --> 04:24:29,400 So, again, I'm reflecting and following up 5130 04:24:29,400 --> 04:24:34,040 on three wonderful presentations that have really highlighted 5131 04:24:34,040 --> 04:24:38,560 the questions that are laid out for us in identifying biomarkers 5132 04:24:38,560 --> 04:24:40,880 and disease treatment targets. 5133 04:24:40,880 --> 04:24:44,800 And just to take a step back to the clinical presentations, 5134 04:24:44,800 --> 04:24:47,000 of what the clinical presentations have taught us 5135 04:24:47,000 --> 04:24:51,000 about pathophysiologies, underlying neurological 5136 04:24:51,000 --> 04:24:55,000 and psychiatric conditions in acute COVID-19, 5137 04:24:55,000 --> 04:24:57,960 a really fantastic UK-wide surveillance study 5138 04:24:57,960 --> 04:25:01,600 has looked at cases of people reporting to the hospital 5139 04:25:01,600 --> 04:25:03,160 with clinical presentations 5140 04:25:03,160 --> 04:25:07,000 that relate to COVID and neuro and psych symptoms. 5141 04:25:07,000 --> 04:25:09,080 And I think what their investigation 5142 04:25:09,080 --> 04:25:11,040 has really highlighted is that there's different 5143 04:25:11,040 --> 04:25:13,280 pathophysiologies underlying the conditions, 5144 04:25:13,280 --> 04:25:16,280 as we've heard from the previous presenters. 5145 04:25:16,280 --> 04:25:18,120 So in this graph, in the first column, 5146 04:25:18,120 --> 04:25:20,440 we have cerebrovascular disorders, 5147 04:25:20,440 --> 04:25:24,200 and these are organized by relative frequency of onset 5148 04:25:24,200 --> 04:25:26,840 related to the onset of respiratory symptoms. 5149 04:25:26,840 --> 04:25:29,400 And the cerebrovascular disorders in the first column 5150 04:25:29,400 --> 04:25:32,120 are starting very early and even pre-dating 5151 04:25:32,120 --> 04:25:34,400 the COVID-19 respiratory symptoms, 5152 04:25:34,400 --> 04:25:37,040 but the other disorders highlighted in the red boxes 5153 04:25:37,040 --> 04:25:39,480 here are disorders that we typically think of 5154 04:25:39,480 --> 04:25:42,320 as being immune mediated or inflammatory diseases, 5155 04:25:42,320 --> 04:25:44,480 as Dr. Nath pointed out beautifully. 5156 04:25:44,480 --> 04:25:46,200 Many of these started a week or two 5157 04:25:46,200 --> 04:25:49,000 after the onset of respiratory symptoms. 5158 04:25:49,000 --> 04:25:50,360 And I think that what this highlights 5159 04:25:50,360 --> 04:25:52,680 is that there are diverse pathophysiologies, 5160 04:25:52,680 --> 04:25:55,200 and we really need to try to understand all of them. 5161 04:25:55,200 --> 04:25:57,320 Next slide, please. 5162 04:25:57,320 --> 04:26:00,680 So thinking about acute COVID-19 and what kinds of biomarkers 5163 04:26:00,680 --> 04:26:04,800 have been revealing and seemingly showing us 5164 04:26:04,800 --> 04:26:06,560 what some of the biological mechanisms 5165 04:26:06,560 --> 04:26:09,880 are in these conditions. And you heard about inflammation 5166 04:26:09,880 --> 04:26:13,560 and looking actually at autopsy samples, 5167 04:26:13,560 --> 04:26:16,120 but in fact, cerebrospinal fluid has been collected 5168 04:26:16,120 --> 04:26:19,320 in limited numbers of people who have had acute COVID-19, 5169 04:26:19,320 --> 04:26:21,560 and they have also revealed neural inflammation. 5170 04:26:21,560 --> 04:26:24,960 This is a very small study of only six people studied early 5171 04:26:24,960 --> 04:26:27,680 in the pandemic who had neurological complications 5172 04:26:27,680 --> 04:26:30,720 during acute COVID-19, and these samples revealed 5173 04:26:30,720 --> 04:26:34,400 elevations in biomarkers of immune activation, 5174 04:26:34,400 --> 04:26:37,040 such as neopterin and beta-2 microglobulin 5175 04:26:37,040 --> 04:26:38,440 in the spinal fluid. 5176 04:26:38,440 --> 04:26:40,760 Here on the left, you can see that the dotted line 5177 04:26:40,760 --> 04:26:44,080 is the normal value in healthy control subjects, 5178 04:26:44,080 --> 04:26:47,640 indicating that inflammation was very prominent in these people. 5179 04:26:47,640 --> 04:26:51,120 At the same time, this group did not definitively 5180 04:26:51,120 --> 04:26:52,640 detect SARS-CoV-2, 5181 04:26:52,640 --> 04:26:54,920 and again confirming what's been pointed out 5182 04:26:54,920 --> 04:26:58,800 in previous talks that viral invasion does not seem 5183 04:26:58,800 --> 04:27:01,120 to be a prominent part of the disorder. 5184 04:27:01,120 --> 04:27:05,720 Next slide, please. So other CSF biomarkers -- 5185 04:27:05,720 --> 04:27:07,760 and you saw this slide briefly earlier -- 5186 04:27:07,760 --> 04:27:09,320 have also been looked at, 5187 04:27:09,320 --> 04:27:11,560 and I think this is particularly of interest in a group 5188 04:27:11,560 --> 04:27:15,600 that's concerned about the onset of neurodegenerative diseases. 5189 04:27:15,600 --> 04:27:17,440 So again, in acute COVID-19, 5190 04:27:17,440 --> 04:27:20,680 CSF samples that have been collected in people with COVID 5191 04:27:20,680 --> 04:27:22,200 and neurologic symptoms 5192 04:27:22,200 --> 04:27:25,320 have revealed changes in amyloid processing, 5193 04:27:25,320 --> 04:27:28,720 so reductions in soluble amyloid precursor protein 5194 04:27:28,720 --> 04:27:32,280 and amyloid beta during acute COVID-19 5195 04:27:32,280 --> 04:27:33,960 with neurologic symptoms. 5196 04:27:33,960 --> 04:27:36,560 I think, again, this is something that raises concerns, 5197 04:27:36,560 --> 04:27:38,920 but we really don't know the long-term implications 5198 04:27:38,920 --> 04:27:40,280 of these findings. 5199 04:27:40,280 --> 04:27:43,760 Next slide, please. How about blood samples? 5200 04:27:43,760 --> 04:27:45,520 And I think it's been very fortunate 5201 04:27:45,520 --> 04:27:47,800 that, of course, blood has been much more readily detected, 5202 04:27:47,800 --> 04:27:49,680 readily measured and collected for research 5203 04:27:49,680 --> 04:27:52,720 purposes in patients with COVID-19. 5204 04:27:52,720 --> 04:27:56,120 So this is a much larger study coming out of NYU 5205 04:27:56,120 --> 04:27:59,800 that collected blood in 246 individuals 5206 04:27:59,800 --> 04:28:03,600 who had acute COVID-19 while they were hospitalized. 5207 04:28:03,600 --> 04:28:05,080 And this study very nicely 5208 04:28:05,080 --> 04:28:08,000 compared levels of neurofilament light chain, 5209 04:28:08,000 --> 04:28:11,800 which is a marker of active neuronal injury, 5210 04:28:11,800 --> 04:28:14,000 as well as glial fibrillary acid protein, 5211 04:28:14,000 --> 04:28:16,440 which is a marker of astrocyte injury. 5212 04:28:16,440 --> 04:28:19,520 And this study revealed quite robust elevations 5213 04:28:19,520 --> 04:28:23,120 in both of these markers in people who had acute COVID-19, 5214 04:28:23,120 --> 04:28:25,400 and they very nicely compared those to people 5215 04:28:25,400 --> 04:28:27,640 who they considered normal, healthy controls as well 5216 04:28:27,640 --> 04:28:30,000 as those with mild cognitive impairment 5217 04:28:30,000 --> 04:28:31,920 and active Alzheimer's disease, 5218 04:28:31,920 --> 04:28:34,120 showing that the extent of these elevations 5219 04:28:34,120 --> 04:28:36,240 was really quite marked, 5220 04:28:36,240 --> 04:28:39,560 even compared to the individuals with neurodegenerative disease. 5221 04:28:39,560 --> 04:28:41,200 I'll say that both these changes, 5222 04:28:41,200 --> 04:28:43,680 as well as the changes in amyloid precursor proteins 5223 04:28:43,680 --> 04:28:45,240 and amyloid measures, 5224 04:28:45,240 --> 04:28:48,400 are also seen in other acute infectious conditions, 5225 04:28:48,400 --> 04:28:50,680 including an acute HIV infection. 5226 04:28:50,680 --> 04:28:52,840 So I think that we have to look at this 5227 04:28:52,840 --> 04:28:54,520 as a marker of an acute injury 5228 04:28:54,520 --> 04:28:57,480 that may not have long-term clinical effects. 5229 04:28:57,480 --> 04:29:01,040 Next slide, please. 5230 04:29:01,040 --> 04:29:03,440 A much more sort of in-depth research study 5231 04:29:03,440 --> 04:29:05,680 has been recently conducted here at Yale 5232 04:29:05,680 --> 04:29:08,440 by one of my collaborators, Dr. Shelli Farhadian, 5233 04:29:08,440 --> 04:29:11,400 where she looked not only at markers in immune activation -- 5234 04:29:11,400 --> 04:29:14,600 and this is looking at CSF cytokines on the left 5235 04:29:14,600 --> 04:29:16,880 where those in purple are those with COVID-19 5236 04:29:16,880 --> 04:29:19,040 and those in green were healthy controls -- 5237 04:29:19,040 --> 04:29:20,800 and showed that the CSF cytokine patterns 5238 04:29:20,800 --> 04:29:23,440 were not only abnormally elevated in the COVID patients, 5239 04:29:23,440 --> 04:29:25,800 but they actually were different than the cytokines 5240 04:29:25,800 --> 04:29:27,800 observed in the blood, suggesting that there's 5241 04:29:27,800 --> 04:29:30,160 a compartmentalized immune reaction. 5242 04:29:30,160 --> 04:29:31,840 She also found that there was an elevation 5243 04:29:31,840 --> 04:29:35,440 in the frequency of B cells in the cerebrospinal fluid. 5244 04:29:35,440 --> 04:29:36,960 And when the B cells -- 5245 04:29:36,960 --> 04:29:39,000 since B cells produce antibodies, 5246 04:29:39,000 --> 04:29:41,200 she investigated whether or not the antibodies 5247 04:29:41,200 --> 04:29:45,800 seem to be directed against SARS-CoV-2 or some other target. 5248 04:29:45,800 --> 04:29:48,400 And in all of the examples, there were antibodies 5249 04:29:48,400 --> 04:29:51,040 detected against SARS-CoV-2 in the spinal fluid, 5250 04:29:51,040 --> 04:29:52,600 and some of these differ than the patterns 5251 04:29:52,600 --> 04:29:53,920 of those in the blood. 5252 04:29:53,920 --> 04:29:55,800 But interestingly, some of these antibodies 5253 04:29:55,800 --> 04:29:58,960 also were autoreactive to brain tissue, 5254 04:29:58,960 --> 04:30:01,440 suggesting an element of autoimmunity 5255 04:30:01,440 --> 04:30:03,640 underlying some of these conditions. 5256 04:30:03,640 --> 04:30:06,320 I'll say that I also indicate on the slide that, again, 5257 04:30:06,320 --> 04:30:09,680 looking for presence of virus, very few published cases 5258 04:30:09,680 --> 04:30:12,000 have detected SARS-CoV-2 in spinal fluid -- 5259 04:30:12,000 --> 04:30:14,800 less than 3% of published cases -- 5260 04:30:14,800 --> 04:30:16,360 suggesting again 5261 04:30:16,360 --> 04:30:20,000 a neuropathogenesis that's really immune mediated 5262 04:30:20,000 --> 04:30:21,720 and potentially vascularly mediated, 5263 04:30:21,720 --> 04:30:23,320 as you've heard from Dr. Nath, 5264 04:30:23,320 --> 04:30:25,560 rather than a direct viral infection. 5265 04:30:25,560 --> 04:30:28,400 Next slide, please. 5266 04:30:28,400 --> 04:30:30,960 So moving to this issue of long COVID -- 5267 04:30:30,960 --> 04:30:32,800 and I think, here, we have many more questions 5268 04:30:32,800 --> 04:30:34,960 than we have answers and data, 5269 04:30:34,960 --> 04:30:38,400 but one can imagine that some of these underlying conditions 5270 04:30:38,400 --> 04:30:41,200 that we're seeing in people who are having persistent issues 5271 04:30:41,200 --> 04:30:43,400 after recovery from acute COVID-19 5272 04:30:43,400 --> 04:30:46,120 could be related to some of the pathophysiologies 5273 04:30:46,120 --> 04:30:49,880 that are seen in acute COVID. Next slide, please. 5274 04:30:49,880 --> 04:30:51,600 -Two minutes remaining. 5275 04:30:51,600 --> 04:30:55,960 -Great. So one possibility is that persistent inflammation 5276 04:30:55,960 --> 04:30:59,440 or ongoing immune activation or abnormalities is underlying 5277 04:30:59,440 --> 04:31:02,400 some of the longer-term complications of COVID 5278 04:31:02,400 --> 04:31:05,200 after recovery from acute illness. 5279 04:31:05,200 --> 04:31:08,000 I have to say, I think we have very little clear evidence 5280 04:31:08,000 --> 04:31:09,960 that that's actually true at this point, 5281 04:31:09,960 --> 04:31:11,880 but many studies are ongoing. 5282 04:31:11,880 --> 04:31:13,680 This is a tiny study of individuals 5283 04:31:13,680 --> 04:31:16,560 who had cancer and neurologic symptoms, 5284 04:31:16,560 --> 04:31:18,160 and those in red here are shown 5285 04:31:18,160 --> 04:31:20,720 who have cancer and neurologic symptoms after COVID, 5286 04:31:20,720 --> 04:31:23,800 versus cancer and neurologic symptoms without COVID. 5287 04:31:23,800 --> 04:31:27,720 And in this study, there was a higher CSF inflammatory score 5288 04:31:27,720 --> 04:31:32,000 in those people who had COVID. Next, please. 5289 04:31:32,000 --> 04:31:33,960 Another nice study has looked at individuals 5290 04:31:33,960 --> 04:31:36,600 who were prospectively studied from the time 5291 04:31:36,600 --> 04:31:40,000 of their acute hospitalization and then three months later. 5292 04:31:40,000 --> 04:31:41,600 And in this study, individuals 5293 04:31:41,600 --> 04:31:44,920 who had very high baseline blood inflammatory markers 5294 04:31:44,920 --> 04:31:47,120 were more likely to have long-term depression 5295 04:31:47,120 --> 04:31:51,920 and neurocognition abnormalities at three months. Next. 5296 04:31:51,920 --> 04:31:53,920 I think both of these studies are just little hints 5297 04:31:53,920 --> 04:31:56,640 that these may be issues, but we really need to understand 5298 04:31:56,640 --> 04:31:59,320 how these relate to more long-term symptoms 5299 04:31:59,320 --> 04:32:01,400 in people who have had milder disease. 5300 04:32:01,400 --> 04:32:03,360 Next slide. 5301 04:32:03,360 --> 04:32:05,360 What about neuroimaging biomarkers? 5302 04:32:05,360 --> 04:32:07,040 You heard again from Dr. Nath 5303 04:32:07,040 --> 04:32:09,720 already about another study, different from this one, 5304 04:32:09,720 --> 04:32:12,400 that found regional hypometabolism, 5305 04:32:12,400 --> 04:32:15,680 changes in glucose uptake in the brain of individuals 5306 04:32:15,680 --> 04:32:19,080 after COVID who were having long-term neurologic symptoms. 5307 04:32:19,080 --> 04:32:21,560 And in this study, the PET metabolic values 5308 04:32:21,560 --> 04:32:25,160 were actually related to the degree of symptoms, 5309 04:32:25,160 --> 04:32:28,880 such as changes in memory, pain symptoms, or anosmia. 5310 04:32:28,880 --> 04:32:31,080 Next slide. 5311 04:32:31,080 --> 04:32:32,800 -Time. 5312 04:32:32,800 --> 04:32:35,240 -So you also heard already about this UK biobank study, 5313 04:32:35,240 --> 04:32:37,320 and I think this is also very convincing 5314 04:32:37,320 --> 04:32:40,200 and concerning that, in people in whom data 5315 04:32:40,200 --> 04:32:42,040 was available before and after COVID, 5316 04:32:42,040 --> 04:32:45,000 there were regional changes in brain structure size. 5317 04:32:45,000 --> 04:32:46,720 Next slide. 5318 04:32:46,720 --> 04:32:48,000 -So, with apologies, Serena, 5319 04:32:48,000 --> 04:32:50,880 we have to go the question and answer. 5320 04:32:50,880 --> 04:32:52,120 -Yeah. That's no problem. 5321 04:32:52,120 --> 04:32:54,080 My last slide is just really a summary 5322 04:32:54,080 --> 04:32:55,840 of the questions to be looked at, 5323 04:32:55,840 --> 04:32:57,920 so the next slide, you can just show this one, 5324 04:32:57,920 --> 04:33:00,800 and looking at targets for treatment. 5325 04:33:00,800 --> 04:33:02,400 Thank you so much. 5326 04:33:07,040 --> 04:33:09,920 -Thank you all very much.

Hi, Penny Dacks again with AFTD. 5339 04:33:48,400 --> 04:33:50,040 Though I should say that I'm not commenting 5340 04:33:50,040 --> 04:33:51,520 right now on behalf of AFTD 5341 04:33:51,520 --> 04:33:54,320 but as a family member of two very sick people, 5342 04:33:54,320 --> 04:33:56,240 including a 10 year old child. 5343 04:33:59,280 --> 04:34:03,640 There's a lot that I think we still need to disentangle, 5344 04:34:03,640 --> 04:34:05,200 right, in terms of, 5345 04:34:05,200 --> 04:34:06,960 and I think you guys did a really great job 5346 04:34:06,960 --> 04:34:08,680 of outlining the different areas 5347 04:34:08,680 --> 04:34:11,760 there where we've got aspects of long-term chronic stress, 5348 04:34:11,760 --> 04:34:13,960 social isolation, anxiety and depression. 5349 04:34:13,960 --> 04:34:15,840 And we know from epidemiology for years 5350 04:34:15,840 --> 04:34:18,280 that those all have links to dementia onset 5351 04:34:18,280 --> 04:34:19,800 that may not necessarily 5352 04:34:19,800 --> 04:34:24,880 be long-term pathological factors there. 5353 04:34:24,880 --> 04:34:28,320 And we can assume that severe acute COVID infection 5354 04:34:28,320 --> 04:34:29,800 that has hospitalization, 5355 04:34:29,800 --> 04:34:33,800 that has ventilation is going to pose hypoxia 5356 04:34:33,800 --> 04:34:37,480 for one thing that could have immediate acute effects 5357 04:34:37,480 --> 04:34:40,000 on vascular function, 5358 04:34:40,000 --> 04:34:44,960 on the underlying neuropathologies of the ADRDs. 5359 04:34:44,960 --> 04:34:48,600 And we have this third situation where you've got young people, 5360 04:34:48,600 --> 04:34:54,480 right, who had mild acute infections 5361 04:34:54,480 --> 04:34:59,160 that are having this long COVID, of chronic fatigue, anxiety, 5362 04:34:59,160 --> 04:35:02,400 depression, headaches, neurological symptoms, 5363 04:35:02,400 --> 04:35:04,400 all different kinds of stuff. 5364 04:35:04,400 --> 04:35:08,800 And every single one of those different clinical situations 5365 04:35:08,800 --> 04:35:11,640 are profoundly important to understand. 5366 04:35:11,640 --> 04:35:14,720 When we think about how this is going to impact 5367 04:35:14,720 --> 04:35:18,320 their long-term risks of dementias. 5368 04:35:18,320 --> 04:35:20,200 And I just wanted to put a plea out there 5369 04:35:20,200 --> 04:35:22,960 that we are very, very careful 5370 04:35:22,960 --> 04:35:26,120 about how we define the work that we do. 5371 04:35:26,120 --> 04:35:29,200 Because the work that's being done in the hospital 5372 04:35:29,200 --> 04:35:32,880 as patients who have severe acute symptoms, 5373 04:35:32,880 --> 04:35:36,600 I think biologically could be very, very different 5374 04:35:36,600 --> 04:35:41,080 from what's happening in the more mild acute 5375 04:35:41,080 --> 04:35:43,640 but chronic situations. 5376 04:35:43,640 --> 04:35:45,120 So it's really just a plea 5377 04:35:45,120 --> 04:35:47,160 that as we come up with a nomenclature 5378 04:35:47,160 --> 04:35:49,640 and as we come up with how we define these things, 5379 04:35:49,640 --> 04:35:51,560 we are very cautious with the data 5380 04:35:51,560 --> 04:35:53,200 that we put in there to make sure 5381 04:35:53,200 --> 04:35:57,800 that these are the separations across these categories 5382 04:35:57,800 --> 04:36:01,200 of clinical situations can be more readily understood. 5383 04:36:01,200 --> 04:36:02,520 So that if you've got blood data 5384 04:36:02,520 --> 04:36:03,880 that's being drawn from the clinic, 5385 04:36:03,880 --> 04:36:07,000 for example, in the hospital, you can better, 5386 04:36:07,000 --> 04:36:12,760 you actually know how severe was that initial acute infection 5387 04:36:12,760 --> 04:36:14,520 and separate that out from the people 5388 04:36:14,520 --> 04:36:16,000 who are two years out 5389 04:36:16,000 --> 04:36:19,000 still having severe cognitive problems. 5390 04:36:19,000 --> 04:36:22,720 So thank you for all the work you're doing. 5391 04:36:22,720 --> 04:36:26,680 -Thank you so much for that personal perspective 5392 04:36:26,680 --> 04:36:31,560 and those important points Serena, did you want to respond? 5393 04:36:31,560 --> 04:36:34,400 -Yeah, sure. That's an absolutely critical point, 5394 04:36:34,400 --> 04:36:36,400 and I think one of the major gaps 5395 04:36:36,400 --> 04:36:38,000 that we have in knowledge 5396 04:36:38,000 --> 04:36:40,840 about what's happening in the nervous system in COVID-19 5397 04:36:40,840 --> 04:36:43,520 is actually in people who have mild disease. 5398 04:36:43,520 --> 04:36:44,840 Most of those individuals 5399 04:36:44,840 --> 04:36:46,360 are never enrolled in research studies, 5400 04:36:46,360 --> 04:36:50,400 and even now, we have very little sort of, you know, 5401 04:36:50,400 --> 04:36:53,120 ability to capture those kinds of data 5402 04:36:53,120 --> 04:36:55,720 in people who have acute COVID-19, right. 5403 04:36:55,720 --> 04:36:58,000 And then there are concerns for research participation 5404 04:36:58,000 --> 04:37:00,800 and infection risk. But it may be that it's a very, 5405 04:37:00,800 --> 04:37:04,000 very different type of trigger of symptoms and of syndromes, 5406 04:37:04,000 --> 04:37:05,680 and the biology may be different. 5407 04:37:05,680 --> 04:37:08,160 So we're taking clues from what we've learned from people 5408 04:37:08,160 --> 04:37:10,600 in whom data and sample, et cetera, 5409 04:37:10,600 --> 04:37:13,960 have been able to be collected. But I think thinking about 5410 04:37:13,960 --> 04:37:16,000 how there may really be different categories, 5411 04:37:16,000 --> 04:37:19,160 and the nomenclature is absolutely critical. 5412 04:37:19,160 --> 04:37:21,080 And one of the things we've learned from COVID 5413 04:37:21,080 --> 04:37:24,560 is there's incredible heterogeneity in this condition, 5414 04:37:24,560 --> 04:37:27,320 in all organ systems in all ways. 5415 04:37:27,320 --> 04:37:29,400 And we have to be very accurate and careful 5416 04:37:29,400 --> 04:37:31,640 making sure we don't group things inaccurately 5417 04:37:31,640 --> 04:37:33,600 because then we will not necessarily 5418 04:37:33,600 --> 04:37:37,160 make the right decisions and recommendations going forward. 5419 04:37:37,160 --> 04:37:38,240 -Thank you. 5420 04:37:38,240 --> 04:37:40,400 -Professor Bovenkamp. 5421 04:37:40,400 --> 04:37:42,160 -Well, Gabriel has his hand up first. 5422 04:37:42,160 --> 04:37:47,320 Sorry, my voice, my mike is back on. 5423 04:37:47,320 --> 04:37:49,080 -Thank you, Natalia.

And thank you to all of you. 5877 05:00:42,200 --> 05:00:44,520 I just wanted to share a few comment things 5878 05:00:44,520 --> 05:00:47,720 that I have heard throughout the sessions. 5879 05:00:47,720 --> 05:00:50,640 I've taken notes, and what I'm looking forward to 5880 05:00:50,640 --> 05:00:53,240 is that at the end of my brief presentation 5881 05:00:53,240 --> 05:00:55,960 that all of you will have an opportunity to jump in 5882 05:00:55,960 --> 05:00:58,480 and either, you know, add, correct or, you know, 5883 05:00:58,480 --> 05:01:01,200 or have, provide different point of view. 5884 05:01:01,200 --> 05:01:04,200 I think that we hear that the great progress has been made, 5885 05:01:04,200 --> 05:01:06,240 but more needs to be done. 5886 05:01:06,240 --> 05:01:09,800 I hear a very strong voice of patients and caregivers 5887 05:01:09,800 --> 05:01:13,600 and across the very broad spectrum 5888 05:01:13,600 --> 05:01:19,880 of input which I think is much needed within different topics. 5889 05:01:19,880 --> 05:01:24,880 I hear that there is an urgent need for methods of prevention, 5890 05:01:24,880 --> 05:01:27,960 for pre-symptomatic vigilance so to speak 5891 05:01:27,960 --> 05:01:30,560 and also for support of those who are living with disease. 5892 05:01:30,560 --> 05:01:33,400 This is the three areas that patients and caregivers 5893 05:01:33,400 --> 05:01:34,760 specifically 5894 05:01:34,760 --> 05:01:36,680 and also the organizations that advocate 5895 05:01:36,680 --> 05:01:40,400 on their behalf have been, have been communicating with us. 5896 05:01:40,400 --> 05:01:43,520 I also hear biomarkers, biomarkers, biomarkers. 5897 05:01:43,520 --> 05:01:46,400 It's, you know, across all of the topics, 5898 05:01:46,400 --> 05:01:50,840 this conversation is, you know, enriched by the fact that, 5899 05:01:50,840 --> 05:01:53,920 you know, biomarkers at every stage of, 5900 05:01:53,920 --> 05:01:57,920 you know, detection, diagnosis, management, treatment, 5901 05:01:57,920 --> 05:02:02,400 response to treatments, prognosis, all of this I think 5902 05:02:02,400 --> 05:02:08,280 in such a complex disease constellation as AD/ADRD is, 5903 05:02:08,280 --> 05:02:10,480 biomarkers are going to make a difference. 5904 05:02:10,480 --> 05:02:14,800 I also hear the theme of a need for novel models, 5905 05:02:14,800 --> 05:02:17,360 new disease biology paradigms. 5906 05:02:17,360 --> 05:02:19,680 And going off the beaten path, so to speak, 5907 05:02:19,680 --> 05:02:22,320 seeking synergies within different diseases 5908 05:02:22,320 --> 05:02:26,880 or also maximizing a divergence in pathological pathways. 5909 05:02:26,880 --> 05:02:30,800 And I think this is something that, you know, all of us, 5910 05:02:30,800 --> 05:02:34,360 you know, in the working group need to go back 5911 05:02:34,360 --> 05:02:37,680 and kind of think about how can we incorporate 5912 05:02:37,680 --> 05:02:40,880 that into our recommendations and make, 5913 05:02:40,880 --> 05:02:42,680 and turn them into milestones. 5914 05:02:42,680 --> 05:02:46,800 Then clinical trials have been, you know, on everybody's mind. 5915 05:02:46,800 --> 05:02:48,640 And you know, there's some diseases 5916 05:02:48,640 --> 05:02:51,400 that have terrific progress already in that directions, 5917 05:02:51,400 --> 05:02:53,320 others that need to move there. 5918 05:02:53,320 --> 05:02:55,960 And I think that that's the voices that we heard. 5919 05:02:55,960 --> 05:02:59,320 And then also one big theme of the need 5920 05:02:59,320 --> 05:03:01,000 for resurgent implementation 5921 05:03:01,000 --> 05:03:04,040 of pragmatic approaches and solutions in ADRD. 5922 05:03:04,040 --> 05:03:06,760 This is something that a lot of you 5923 05:03:06,760 --> 05:03:11,640 have been commenting on throughout the summit. 5924 05:03:11,640 --> 05:03:17,280 I'm going to go into, if my slides allow me, 5925 05:03:17,280 --> 05:03:22,400 I'm going to go into topics specific, 5926 05:03:22,400 --> 05:03:24,680 comments or themes that I have captured 5927 05:03:24,680 --> 05:03:26,520 as I was listening to the discussion 5928 05:03:26,520 --> 05:03:28,640 following the conversations 5929 05:03:28,640 --> 05:03:32,080 within the health equity discussion. 5930 05:03:32,080 --> 05:03:36,760 There was a clear kind of underscoring of the need 5931 05:03:36,760 --> 05:03:39,080 for biomarkers to understand ADRD 5932 05:03:39,080 --> 05:03:42,640 in diverse populations with dedicated studies 5933 05:03:42,640 --> 05:03:46,320 of minoritized populations covering entire lifespan. 5934 05:03:46,320 --> 05:03:49,600 And with special focus on brain donation that has to, 5935 05:03:49,600 --> 05:03:52,960 has to help us advance understanding of disease 5936 05:03:52,960 --> 05:03:57,320 that's specific to the diverse populations. 5937 05:03:57,320 --> 05:03:59,000 There's been a call for research studies 5938 05:03:59,000 --> 05:04:02,600 that go wide and deep highlighting multiple approaches 5939 05:04:02,600 --> 05:04:06,080 that, you know, that are necessary to solve, 5940 05:04:06,080 --> 05:04:09,720 to solve the problems or give, find the answers. 5941 05:04:09,720 --> 05:04:11,360 Breaking the barriers to recruitment 5942 05:04:11,360 --> 05:04:13,600 of diverse populations. 5943 05:04:13,600 --> 05:04:16,520 There was a theme of improving access to clinical trials, 5944 05:04:16,520 --> 05:04:19,000 especially to ensure equity. 5945 05:04:19,000 --> 05:04:22,520 Making sure that the trials that are partnered through NIH 5946 05:04:22,520 --> 05:04:23,960 are free of cost. 5947 05:04:23,960 --> 05:04:26,080 That's a patient's perspective that we heard. 5948 05:04:26,080 --> 05:04:29,520 Gene environment interaction has been a really big theme 5949 05:04:29,520 --> 05:04:32,800 in a discussion following the health equity session. 5950 05:04:32,800 --> 05:04:35,920 Understanding that including health disparities 5951 05:04:35,920 --> 05:04:38,000 related to life course 5952 05:04:38,000 --> 05:04:41,000 or life course of environmental exposures 5953 05:04:41,000 --> 05:04:44,520 such as nutrition, lifestyle, toxicities, 5954 05:04:44,520 --> 05:04:48,080 and the need for normal models like organelles, for example, 5955 05:04:48,080 --> 05:04:50,640 to thoroughly account for the variability 5956 05:04:50,640 --> 05:04:53,560 and specifics of diverse environments. 5957 05:04:53,560 --> 05:04:58,240 There was a theme for, of the need to encourage and expand 5958 05:04:58,240 --> 05:05:02,160 by specimen and tissue collection beyond brain tissue, 5959 05:05:02,160 --> 05:05:04,480 including retinal in this case for discovery 5960 05:05:04,480 --> 05:05:08,480 in order to consider a whole person. 5961 05:05:08,480 --> 05:05:14,520 And perspectives from a caregiver 5962 05:05:14,520 --> 05:05:17,120 that we heard in that particular session 5963 05:05:17,120 --> 05:05:20,000 included the transparency and communication 5964 05:05:20,000 --> 05:05:22,960 with caregivers regarding diagnosis and prognosis. 5965 05:05:22,960 --> 05:05:26,640 That them continued to emerge in different topics. 5966 05:05:26,640 --> 05:05:27,840 And I think that that's something 5967 05:05:27,840 --> 05:05:30,480 that each working group has to, 5968 05:05:30,480 --> 05:05:35,000 has to, you know, accommodate for as we think about, 5969 05:05:35,000 --> 05:05:37,560 as we think about recommendations going forward. 5970 05:05:37,560 --> 05:05:39,600 And finally, a strong foundation 5971 05:05:39,600 --> 05:05:41,600 for developing diverse workforce, 5972 05:05:41,600 --> 05:05:43,320 retention and support of mentors 5973 05:05:43,320 --> 05:05:46,880 at all stages of their career span. 5974 05:05:46,880 --> 05:05:50,920 In the FTD group discussion, 5975 05:05:50,920 --> 05:05:52,920 biomarkers were front and center. 5976 05:05:52,920 --> 05:05:57,520 Almost every, every comment had some reference to biomarkers 5977 05:05:57,520 --> 05:06:01,560 including particularly pre- symptomatic neural degeneration, 5978 05:06:01,560 --> 05:06:03,280 you know, with a clinical translation 5979 05:06:03,280 --> 05:06:06,760 for current biomarkers such as NfL being an urgent need 5980 05:06:06,760 --> 05:06:09,800 and developing novel ones for disease progression monitoring, 5981 05:06:09,800 --> 05:06:13,280 et cetera. Innovative clinical markers 5982 05:06:13,280 --> 05:06:18,600 including those that capture social, behavioral and movement, 5983 05:06:18,600 --> 05:06:24,520 you know, metrics that may help make, 5984 05:06:24,520 --> 05:06:26,000 you know, participation and research 5985 05:06:26,000 --> 05:06:31,720 as well as perhaps further translation 5986 05:06:31,720 --> 05:06:35,320 of the recent research findings into care 5987 05:06:35,320 --> 05:06:39,360 and make those accessible. And also developing novel 5988 05:06:39,360 --> 05:06:42,760 endpoints that capture the broad spectrum of clinical disease. 5989 05:06:42,760 --> 05:06:45,440 So that's something that was very, 5990 05:06:45,440 --> 05:06:48,440 very robust in terms of discussion. 5991 05:06:48,440 --> 05:06:51,320 Also within the FTD session discussion, 5992 05:06:51,320 --> 05:06:53,880 there was a lot of focus on prevention 5993 05:06:53,880 --> 05:06:56,520 and the need to assist those who are living with FTD. 5994 05:06:56,520 --> 05:07:00,120 And I think that that's a very strong patient 5995 05:07:00,120 --> 05:07:02,520 as well as a caretaker perspective. 5996 05:07:02,520 --> 05:07:05,040 A risk and resilience factor characterization 5997 05:07:05,040 --> 05:07:08,200 came into discussion and also continued to be a theme 5998 05:07:08,200 --> 05:07:10,400 throughout the rest of the summit. 5999 05:07:10,400 --> 05:07:15,240 Quantitative data was highlighted, 6000 05:07:15,240 --> 05:07:17,720 the need for quantitative data was highlighted. 6001 05:07:17,720 --> 05:07:21,760 Not only the all mix level but the level of protein biology 6002 05:07:21,760 --> 05:07:23,160 and other precision methods 6003 05:07:23,160 --> 05:07:25,560 of molecular characterization of disease. 6004 05:07:25,560 --> 05:07:28,560 And then from the patient perspective, 6005 05:07:28,560 --> 05:07:32,560 the question of, you know, delayed diagnosis, 6006 05:07:32,560 --> 05:07:34,880 is the detection delayed diagnosis. 6007 05:07:34,880 --> 05:07:38,200 And reconsideration of this kind of single diagnosis 6008 05:07:38,200 --> 05:07:43,120 box that patients are frequently dealing with in real world. 6009 05:07:43,120 --> 05:07:45,320 For VCID session, 6010 05:07:45,320 --> 05:07:48,200 there was a very robust scientific discussion 6011 05:07:48,200 --> 05:07:50,320 that followed presentation. 6012 05:07:50,320 --> 05:07:53,920 And there were certainly VCID has been identified 6013 05:07:53,920 --> 05:07:57,080 as one of the areas of clear intersection of science 6014 05:07:57,080 --> 05:08:01,960 and, you know, emerging need to explore novel pathways 6015 05:08:01,960 --> 05:08:05,360 and also finetuning the existing models. 6016 05:08:05,360 --> 05:08:07,920 VCID is dementia and sleep intersection 6017 05:08:07,920 --> 05:08:11,200 was used as an example of kind of evolving 6018 05:08:11,200 --> 05:08:14,080 understanding of the disease with, 6019 05:08:14,080 --> 05:08:17,200 you know, moving from the concepts 6020 05:08:17,200 --> 05:08:19,800 of ischemic models of disease 6021 05:08:19,800 --> 05:08:23,880 into understanding the mechanisms of clearance that, 6022 05:08:23,880 --> 05:08:27,840 you know, may have that novel pivot 6023 05:08:27,840 --> 05:08:31,800 in our understanding of disease. 6024 05:08:31,800 --> 05:08:34,000 And as a result, developing novel 6025 05:08:34,000 --> 05:08:36,960 approaches to nonischemic mechanisms, 6026 05:08:36,960 --> 05:08:40,320 for example, in this particular area 6027 05:08:40,320 --> 05:08:43,200 including the impaired clearance. 6028 05:08:43,200 --> 05:08:45,440 There was a very robust 6029 05:08:45,440 --> 05:08:50,080 and also I think fascinating discussion with regard 6030 05:08:50,080 --> 05:08:56,040 to the nuances of how we approach modeling of ischemia 6031 05:08:56,040 --> 05:09:00,400 and in general VCID considering the diversity 6032 05:09:00,400 --> 05:09:02,760 in cell types that we are, 6033 05:09:02,760 --> 05:09:06,000 you know, increasingly understand original blood 6034 05:09:06,000 --> 05:09:08,440 flows in the brain, vascular reactivity, 6035 05:09:08,440 --> 05:09:09,840 et cetera, et cetera. 6036 05:09:09,840 --> 05:09:12,600 All of the foundations of the VCID disease 6037 05:09:12,600 --> 05:09:14,400 processes as we know them right now. 6038 05:09:14,400 --> 05:09:17,800 But with a broadening so to speak spectrum 6039 05:09:17,800 --> 05:09:20,960 and portfolio of understanding of these nuances 6040 05:09:20,960 --> 05:09:23,280 I think is something that we need to think 6041 05:09:23,280 --> 05:09:30,000 on how that may enhance our recommendations going forward. 6042 05:09:30,000 --> 05:09:32,600 And also, big focus on reproducibility, 6043 05:09:32,600 --> 05:09:35,000 repeatability of models at every stage 6044 05:09:35,000 --> 05:09:38,640 including design, data collection, data sharing. 6045 05:09:38,640 --> 05:09:41,680 Understanding VCID is a systemic disease 6046 05:09:41,680 --> 05:09:44,720 and the role in that of circulating biomarkers. 6047 05:09:44,720 --> 05:09:46,520 Obviously, this I something that, 6048 05:09:46,520 --> 05:09:48,000 you know, being done currently, 6049 05:09:48,000 --> 05:09:50,160 but there are perhaps opportunities for novel 6050 05:09:50,160 --> 05:09:52,200 approaches and emerging, 6051 05:09:52,200 --> 05:09:55,880 using emerging systemic circulating biomarkers 6052 05:09:55,880 --> 05:09:58,280 as well as imaging technologies. 6053 05:09:58,280 --> 05:10:01,520 And I just wanted to quote Dr. Seshadri's, 6054 05:10:01,520 --> 05:10:04,920 I think kind of a statement 6055 05:10:04,920 --> 05:10:07,320 which kind of culminated this discussion of VCID 6056 05:10:07,320 --> 05:10:12,560 is that perhaps the science or our approach to science in VCID 6057 05:10:12,560 --> 05:10:15,200 is going to, you know, through increasing complexity 6058 05:10:15,200 --> 05:10:17,000 until we arrive at some simplicity. 6059 05:10:17,000 --> 05:10:20,320 And I think that that may be, may be the thing here as well. 6060 05:10:20,320 --> 05:10:23,880 In LBD, group discussion, 6061 05:10:23,880 --> 05:10:27,520 I think that the big things were sharing of information 6062 05:10:27,520 --> 05:10:30,560 across the disease entities considering how heterogeneous 6063 05:10:30,560 --> 05:10:34,040 and also perhaps in some areas overlapping, 6064 05:10:34,040 --> 05:10:37,480 you know, disease pathology clinical, 6065 05:10:37,480 --> 05:10:41,560 clinical syndromes that we are dealing with. 6066 05:10:41,560 --> 05:10:46,480 Making sure that the dialogue is accessible for the public 6067 05:10:46,480 --> 05:10:50,240 in conveying the complexity of disease. 6068 05:10:50,240 --> 05:10:56,040 The patient kind of a guidance to us with regard 6069 05:10:56,040 --> 05:10:59,840 to access to clinical trials across the spectrum of LBD, 6070 05:10:59,840 --> 05:11:03,360 especially as diagnostic precision evolves and patients 6071 05:11:03,360 --> 05:11:06,000 seek new opportunities as their diagnosis 6072 05:11:06,000 --> 05:11:08,520 of which is actually a theme that came up 6073 05:11:08,520 --> 05:11:10,920 in at least a couple of sessions throughout the summit. 6074 05:11:10,920 --> 05:11:15,280 Which I thought was very, very curious. 6075 05:11:15,280 --> 05:11:18,120 Biomarkers were front and center with LBD as well. 6076 05:11:18,120 --> 05:11:21,160 Pre-symptomatic, pre-clinical diagnostic prognostic, 6077 05:11:21,160 --> 05:11:27,560 all of these have been on the mind of our scientists 6078 05:11:27,560 --> 05:11:32,520 as well as patients and families and care partners. 6079 05:11:32,520 --> 05:11:36,000 Focus on disease heterogeneities also led to a discussion 6080 05:11:36,000 --> 05:11:40,160 of both clinical and precision characterization. 6081 05:11:40,160 --> 05:11:43,720 Moving away from silos and again clearer communications. 6082 05:11:43,720 --> 05:11:46,160 And then developing opportunities for disease 6083 05:11:46,160 --> 05:11:48,800 modification and symptom control of patients 6084 05:11:48,800 --> 05:11:54,280 who are already living with LBDs is something that, again, 6085 05:11:54,280 --> 05:11:57,800 was reverberated in the discussion session 6086 05:11:57,800 --> 05:12:00,160 following this. 6087 05:12:00,160 --> 05:12:03,160 Now this morning we had a very robust discussion 6088 05:12:03,160 --> 05:12:06,360 following the mixed etiology dementia session. 6089 05:12:06,360 --> 05:12:08,440 It was an outstanding session. 6090 05:12:08,440 --> 05:12:11,720 And I think there was quite a bit of caregiver 6091 05:12:11,720 --> 05:12:14,040 and patient perspective 6092 05:12:14,040 --> 05:12:19,840 that was introduced in the, in the discussion there. 6093 05:12:19,840 --> 05:12:23,640 The need for engagement across the entire spectrum of disease 6094 05:12:23,640 --> 05:12:26,000 and transparency in communication 6095 05:12:26,000 --> 05:12:29,400 was underlined multiple times. 6096 05:12:29,400 --> 05:12:32,160 Opportunities to impact care and engagement 6097 05:12:32,160 --> 05:12:35,200 via a compassionate and culturally appropriate detection 6098 05:12:35,200 --> 05:12:36,840 and diagnosis process. 6099 05:12:36,840 --> 05:12:39,120 So this is something that I wanted to personally thank 6100 05:12:39,120 --> 05:12:43,680 for this feedback from our participants. 6101 05:12:43,680 --> 05:12:46,600 And I think that this is duly noted 6102 05:12:46,600 --> 05:12:49,680 by the members of the MED working group 6103 05:12:49,680 --> 05:12:54,800 but as well as our entire, entire community. 6104 05:12:54,800 --> 05:12:57,520 There was a note of consideration of provider 6105 05:12:57,520 --> 05:13:00,400 burden and wellbeing, which obviously contributes 6106 05:13:00,400 --> 05:13:03,960 in some sort of either positive perpetuating cycle 6107 05:13:03,960 --> 05:13:06,880 or perhaps an ambitious cycle on the other, 6108 05:13:06,880 --> 05:13:08,800 on the other side of the equation 6109 05:13:08,800 --> 05:13:13,200 where we need to ensure that the providers remain engaged 6110 05:13:13,200 --> 05:13:19,200 and well in being able to provide the needed compassion 6111 05:13:19,200 --> 05:13:21,600 for the patients and families. 6112 05:13:21,600 --> 05:13:24,640 I also enjoyed the discussion on research 6113 05:13:24,640 --> 05:13:26,720 that's needed on cultural aspects 6114 05:13:26,720 --> 05:13:28,880 of risk and benefit perception 6115 05:13:28,880 --> 05:13:32,000 and potentially policy research into economic impact 6116 05:13:32,000 --> 05:13:35,800 of screening and early detection of cognitive impairment 6117 05:13:35,800 --> 05:13:37,760 and dementia on diverse populations. 6118 05:13:37,760 --> 05:13:39,520 I think it's a very important 6119 05:13:39,520 --> 05:13:41,680 and potentially very impactful area 6120 05:13:41,680 --> 05:13:46,480 that we may need to address. We also had opportunities to, 6121 05:13:46,480 --> 05:13:49,280 or discussed opportunities to amplify effectiveness 6122 05:13:49,280 --> 05:13:51,960 of multiple approaches via harmonization 6123 05:13:51,960 --> 05:13:55,000 between MED and VCID topics. 6124 05:13:55,000 --> 05:14:00,600 And then also, the important care partners input from, 6125 05:14:00,600 --> 05:14:07,240 that we again restated from both, from the beginning, 6126 05:14:07,240 --> 05:14:10,000 from the research concept from one side of the spectrum 6127 05:14:10,000 --> 05:14:15,600 to execution of research, and this input is needed. 6128 05:14:15,600 --> 05:14:18,640 There were a few important points in post-TBI, 6129 05:14:18,640 --> 05:14:21,800 AD and ADRD session that I have captured, 6130 05:14:21,800 --> 05:14:27,800 and one of them is central role of biomarkers in diagnosis 6131 05:14:27,800 --> 05:14:34,000 that has been discussed with a great degree of robustness. 6132 05:14:34,000 --> 05:14:36,360 In the face of clinical heterogeneity 6133 05:14:36,360 --> 05:14:39,520 of post-TBI ADRD syndromes, 6134 05:14:39,520 --> 05:14:42,880 I think the panel has ultimately arrived 6135 05:14:42,880 --> 05:14:47,120 at a conclusion that biomarkers in this, 6136 05:14:47,120 --> 05:14:51,800 in this role, would provide probably a greater degree 6137 05:14:51,800 --> 05:14:54,200 of fidelity of diagnosis. 6138 05:14:54,200 --> 05:14:56,120 There was also a very robust discussion 6139 05:14:56,120 --> 05:14:59,800 of post-TBI ADRD versus CTE, 6140 05:14:59,800 --> 05:15:02,000 chronic traumatic encephalopathy, 6141 05:15:02,000 --> 05:15:05,960 where the acknowledgement was made that the study design, 6142 05:15:05,960 --> 05:15:10,400 include specifics of exposure history and biomarker arrays 6143 05:15:10,400 --> 05:15:13,600 are needed to differentiate between the impact 6144 05:15:13,600 --> 05:15:16,960 of acute versus chronic injury. 6145 05:15:16,960 --> 05:15:20,080 There was also point discuss regarding standardization 6146 05:15:20,080 --> 05:15:22,880 and prioritization of translational models. 6147 05:15:22,880 --> 05:15:26,440 A note has been made of a great existing history 6148 05:15:26,440 --> 05:15:32,760 of TBI models prior and also ongoing work done 6149 05:15:32,760 --> 05:15:37,080 by Veterans Administration Department of Defense 6150 05:15:37,080 --> 05:15:41,200 in collaboration with NIH, both NIA and NIDS, 6151 05:15:41,200 --> 05:15:45,720 and these collaborations perhaps are best to be maximized 6152 05:15:45,720 --> 05:15:50,680 on as the models of post-TBI, AD and ADRD are being developed. 6153 05:15:50,680 --> 05:15:53,200 And then of course a very important patient perspective 6154 05:15:53,200 --> 05:15:54,880 that was proposed into this discussion 6155 05:15:54,880 --> 05:15:58,600 with regard to availability and accessibility of public 6156 05:15:58,600 --> 05:16:01,200 facing education in this area. 6157 05:16:01,200 --> 05:16:06,960 I made also a few notes with regard to our late session. 6158 05:16:06,960 --> 05:16:08,720 The discussion was also robust, 6159 05:16:08,720 --> 05:16:12,600 and I think the emerging themes were that there's a need 6160 05:16:12,600 --> 05:16:16,200 for harmonization of data and sample collection. 6161 05:16:16,200 --> 05:16:23,120 And you know, using this in order to benefit other fields 6162 05:16:23,120 --> 05:16:24,920 related within the ADRD 6163 05:16:24,920 --> 05:16:27,480 but also perhaps neurological disorders 6164 05:16:27,480 --> 05:16:30,400 or brain disorders outside of ADRD as well. 6165 05:16:30,400 --> 05:16:34,080 There was a discussion on VCID and late interface, 6166 05:16:34,080 --> 05:16:40,000 particularly with a good proportion of, 6167 05:16:40,000 --> 05:16:45,720 you know, nonagenarians or late octogenarians who survive 6168 05:16:45,720 --> 05:16:51,440 and are diagnosed with late disorder or syndrome. 6169 05:16:51,440 --> 05:16:57,040 I should say they also have a high predominance 6170 05:16:57,040 --> 05:17:00,240 of cerebral vascular findings and exploring 6171 05:17:00,240 --> 05:17:03,000 or exploiting this opportunity 6172 05:17:03,000 --> 05:17:06,560 to study coexistence of this type of pathology, 6173 05:17:06,560 --> 05:17:12,600 neuropathology offers great opportunities to address 6174 05:17:12,600 --> 05:17:15,600 some of the, you know, evolving pathophysiology. 6175 05:17:15,600 --> 05:17:19,880 And in this context, the role of perivascular spaces 6176 05:17:19,880 --> 05:17:23,920 and, you know, clearance in the brain, 6177 05:17:23,920 --> 05:17:26,920 proteinopathies, you know, in the brain was addressed 6178 05:17:26,920 --> 05:17:29,280 as well as opportunities to study 6179 05:17:29,280 --> 05:17:33,560 let's say impact of chronic sleep disorders 6180 05:17:33,560 --> 05:17:35,600 in this patient population. 6181 05:17:35,600 --> 05:17:38,600 There was also a discussion on clinical diagnosis readiness, 6182 05:17:38,600 --> 05:17:41,400 including biomarkers, clinical criteria 6183 05:17:41,400 --> 05:17:45,800 that are needed to validate prospectively the diagnosis 6184 05:17:45,800 --> 05:17:48,480 and to give options for patients and families. 6185 05:17:48,480 --> 05:17:51,040 And I think while the jury is still out on 6186 05:17:51,040 --> 05:17:55,680 where is the risk and benefit ratio stands with regard 6187 05:17:55,680 --> 05:17:58,720 to whether we want to quote/unquote rush in 6188 05:17:58,720 --> 05:18:00,600 in providing a diagnosis to a patient 6189 05:18:00,600 --> 05:18:02,240 or whether we should step back 6190 05:18:02,240 --> 05:18:05,640 until we are actually able to provide something that, 6191 05:18:05,640 --> 05:18:09,200 you know, the diagnosis that not only, 6192 05:18:09,200 --> 05:18:12,840 you know, not only a preliminary but also actionable. 6193 05:18:12,840 --> 05:18:15,920 I think that's the sort of a discussion 6194 05:18:15,920 --> 05:18:17,560 that we will continue to have over 6195 05:18:17,560 --> 05:18:21,120 the, you know, over the next few years. 6196 05:18:21,120 --> 05:18:25,000 And I'll be very interested to see how much progress 6197 05:18:25,000 --> 05:18:27,800 we will make in this space in the next three years. 6198 05:18:27,800 --> 05:18:30,960 Because it clearly in the prior three years, you know, 6199 05:18:30,960 --> 05:18:34,720 since the LATE has been introduced TDP 6200 05:18:34,720 --> 05:18:38,200 for the three topic has been introduced in this context, 6201 05:18:38,200 --> 05:18:41,320 so much progress has been already established. 6202 05:18:41,320 --> 05:18:44,560 And we finished off with a COVID session 6203 05:18:44,560 --> 05:18:47,760 which, you know is just very fresh in our memory. 6204 05:18:47,760 --> 05:18:50,320 And due to my technical errors, 6205 05:18:50,320 --> 05:18:53,600 I have not been able to update my slides very thoroughly. 6206 05:18:53,600 --> 05:18:56,600 But what I heard in our discussion, 6207 05:18:56,600 --> 05:18:58,120 which was a fantastic discussion, 6208 05:18:58,120 --> 05:19:00,400 and I thank all the panelists, is that, you know, 6209 05:19:00,400 --> 05:19:04,200 data sharing is something that is urgently needed. 6210 05:19:04,200 --> 05:19:08,200 You know, data harmonization, syndrome characterizations 6211 05:19:08,200 --> 05:19:11,080 and, you know, focusing on detection, 6212 05:19:11,080 --> 05:19:14,640 you know, of the COVID-19 exposures in patients 6213 05:19:14,640 --> 05:19:16,240 not only

I think she actually has departed. 6584 05:38:16,600 --> 05:38:19,400 -Well, I'm really sorry to hear that. 6585 05:38:19,400 --> 05:38:23,760 She's been trying to make a point with regard to, 6586 05:38:23,760 --> 05:38:26,800 you know, root causes of mixed dementia pathology, 6587 05:38:26,800 --> 05:38:28,240 and I think that she made a comment 6588 05:38:28,240 --> 05:38:31,000 in one of the either MED sessions, 6589 05:38:31,000 --> 05:38:32,920 or late sessions, 6590 05:38:32,920 --> 05:38:36,360 and I think that that's something 6591 05:38:36,360 --> 05:38:39,200 that we could not get to that time. 6592 05:38:39,200 --> 05:38:43,560 And I'm really sorry she hasn't had a chance to stay with us, 6593 05:38:43,560 --> 05:38:47,680 to answer. But I think we all agree, 6594 05:38:47,680 --> 05:38:50,000 this is what this work is all about. 6595 05:38:50,000 --> 05:38:54,400 Okay, I have Sonya Valab next on the -- online. 6596 05:38:54,400 --> 05:38:55,960 -Hi. 6597 05:38:55,960 --> 05:38:59,840 Thank you so much for making the time for me to speak. 6598 05:38:59,840 --> 05:39:02,280 So I'll quickly introduce myself first. 6599 05:39:02,280 --> 05:39:03,920 So I'm Sonya Valab. 6600 05:39:03,920 --> 05:39:07,000 I run a prion lab at the Brode Institute in Cambridge, 6601 05:39:07,000 --> 05:39:11,400 Massachusetts, where we work on drug develop, 6602 05:39:11,400 --> 05:39:14,080 biomarker development, natural history, 6603 05:39:14,080 --> 05:39:15,520 et cetera, for prion disease, 6604 05:39:15,520 --> 05:39:18,600 which as you all know is a rapidly-progressive, 6605 05:39:18,600 --> 05:39:21,880 currently untreatable dementia. 6606 05:39:21,880 --> 05:39:24,800 I'm also at risk myself for genetic prion disease, 6607 05:39:24,800 --> 05:39:27,800 so I inherited a fatal mutation 6608 05:39:27,800 --> 05:39:29,520 in the prion protein gene from my mom, 6609 05:39:29,520 --> 05:39:33,000 who died of genetic prion disease in 2010. 6610 05:39:33,000 --> 05:39:35,720 So I've been on the patient side 6611 05:39:35,720 --> 05:39:38,600 and on the caregiver side of this disease, 6612 05:39:38,600 --> 05:39:41,800 as well as having, inspired by that experience 6613 05:39:41,800 --> 05:39:45,240 to get into the research side. 6614 05:39:45,240 --> 05:39:47,240 So all of that is a preface to say 6615 05:39:47,240 --> 05:39:51,120 that I really just have a targeted plea for the committee. 6616 05:39:51,120 --> 05:39:52,680 Thank you for all of the great work 6617 05:39:52,680 --> 05:39:56,040 that you're doing on Alzheimer's and related dementias, 6618 05:39:56,040 --> 05:39:58,240 and I just want to raise for consideration 6619 05:39:58,240 --> 05:40:01,600 the possibility that prion disease could be named 6620 05:40:01,600 --> 05:40:04,960 among the Alzheimer's disease-related dementias. 6621 05:40:04,960 --> 05:40:07,400 I think, mechanistically, we've seen over the past 6622 05:40:07,400 --> 05:40:09,480 few years a real sort of dovetailing 6623 05:40:09,480 --> 05:40:12,600 of some of the insights in the prion field 6624 05:40:12,600 --> 05:40:17,200 that have sort of come out of propagated prion misfolding, 6625 05:40:17,200 --> 05:40:19,440 including diagnostic assays 6626 05:40:19,440 --> 05:40:22,960 that leverage the sort of prion concept, 6627 05:40:22,960 --> 05:40:25,320 but now have been applied more broadly 6628 05:40:25,320 --> 05:40:26,920 to other neurodegenerative diseases, 6629 05:40:26,920 --> 05:40:30,920 in which we see templated protein misfolding. 6630 05:40:30,920 --> 05:40:33,480 And on the flip side, for example, 6631 05:40:33,480 --> 05:40:36,480 much of the biomarker work and need for better biomarkers 6632 05:40:36,480 --> 05:40:39,280 that was discussed earlier this afternoon 6633 05:40:39,280 --> 05:40:43,600 and in these past two days certainly has enriched our work, 6634 05:40:43,600 --> 05:40:45,360 as we look for many of the same biomarkers 6635 05:40:45,360 --> 05:40:47,400 in our natural history work. 6636 05:40:47,400 --> 05:40:51,760 On the theme of prevention and pre-symptomatic vigilance, 6637 05:40:51,760 --> 05:40:55,080 this is an area where we have really tried to advocate -- 6638 05:40:55,080 --> 05:40:57,760 you know, myself as a healthy carrier myself -- 6639 05:40:57,760 --> 05:41:02,040 for novel biomarker-based and genetically-informed 6640 05:41:02,040 --> 05:41:05,320 clinical trial models, and I think there could be 6641 05:41:05,320 --> 05:41:07,800 shared learnings across these diseases. 6642 05:41:07,800 --> 05:41:12,440 So with that, I'll just say I think very much hearing 6643 05:41:12,440 --> 05:41:15,400 the themes that have been touched on, 6644 05:41:15,400 --> 05:41:17,440 I think we feel a kinship with this community, 6645 05:41:17,440 --> 05:41:19,600 and see a lot of research questions, tools, 6646 05:41:19,600 --> 05:41:23,040 and needs that are shared across these domains. 6647 05:41:23,040 --> 05:41:25,040 So I would love for prion disease 6648 05:41:25,040 --> 05:41:28,520 to be considered among the list of diseases. 6649 05:41:28,520 --> 05:41:30,640 Thanks so much. 6650 05:41:30,640 --> 05:41:32,320 -Thank you, Sonya. 6651 05:41:32,320 --> 05:41:35,920 -I wonder if Ryan wants to go near this one. 6652 05:41:35,920 --> 05:41:40,600 We've discussed this multiple times, Sonya, 6653 05:41:40,600 --> 05:41:43,800 and from what we can figure out, 6654 05:41:43,800 --> 05:41:48,440 it would take somebody to go to Congress to change it. 6655 05:41:48,440 --> 05:41:51,720 Now, it's not impossible, so you should think about it, 6656 05:41:51,720 --> 05:41:55,040 but Congress, we understand, made this

We know what we don't know, 6991 06:00:06,360 --> 06:00:09,720 and we have a path forward that we think, 6992 06:00:09,720 --> 06:00:11,680 you know, will get us the answers in the end. 6993 06:00:11,680 --> 06:00:15,440 So we call it the known unknowns. 6994 06:00:15,440 --> 06:00:18,920 Then, there is the issue of the unknown unknowns, 6995 06:00:18,920 --> 06:00:22,360 and that's usually the scariest part of the business, 6996 06:00:22,360 --> 06:00:25,000 where you think you know what the problem is. 6997 06:00:25,000 --> 06:00:26,640 Spend 10 years, and it doesn't work, 6998 06:00:26,640 --> 06:00:28,320 and you realize, well, 6999 06:00:28,320 --> 06:00:30,800 I made some assumptions that were wrong. 7000 06:00:30,800 --> 06:00:36,200 I didn't know X, Y, or Z, and that's led to the final failure. 7001 06:00:36,200 --> 06:00:41,800 So you always have to think that, you know, as a community, 7002 06:00:41,800 --> 06:00:45,040 we tend to want to look under the lamp post, 7003 06:00:45,040 --> 06:00:47,360 and that's what we know. 7004 06:00:47,360 --> 06:00:50,880 That's the known unknowns, but we've got to be really careful. 7005 06:00:50,880 --> 06:00:53,080 There's something out there beyond the lamp post 7006 06:00:53,080 --> 06:00:56,520 that's really relevant to what we need to do. 7007 06:00:56,520 --> 06:01:01,800 And so, that's, I think, keeping your eye out for things 7008 06:01:01,800 --> 06:01:04,960 that are going on in other areas of biology -- 7009 06:01:04,960 --> 06:01:09,640 cancer, you know, basic molecular biology. 7010 06:01:09,640 --> 06:01:14,800 Sometimes that's where the real breakthroughs come from, 7011 06:01:14,800 --> 06:01:21,280 and so, I think that's how I look at the picture we have, 7012 06:01:21,280 --> 06:01:22,800 where we are now. 7013 06:01:22,800 --> 06:01:26,920 The recommendations that were put together here, 7014 06:01:26,920 --> 06:01:31,120 I think, are, you know, very well thought-out, 7015 06:01:31,120 --> 06:01:38,120 and we can work with those, and make progress. 7016 06:01:38,120 --> 06:01:39,720 It's not going to be easy, 7017 06:01:39,720 --> 06:01:43,120 but I think, you know, with the workforce dedication 7018 06:01:43,120 --> 06:01:47,200 and the funding that's now available through NAPA, 7019 06:01:47,200 --> 06:01:49,400 we can really make progress. 7020 06:01:49,400 --> 06:01:53,880 So I'm very optimistic, and a lot of the optimism 7021 06:01:53,880 --> 06:01:57,800 is because the last two days, the people that have, you know, 7022 06:01:57,800 --> 06:02:03,160 shown their passion and dedication for this field. 7023 06:02:03,160 --> 06:02:06,440 I think we have a good team. 7024 06:02:06,440 --> 06:02:09,000 We need more players, but we have a good team. 7025 06:02:09,000 --> 06:02:12,160 So I want to thank everybody for the teamwork 7026 06:02:12,160 --> 06:02:14,360 to put this together, and for all the work 7027 06:02:14,360 --> 06:02:17,160 you're going to do in the next three years. 7028 06:02:17,160 --> 06:02:20,520 So, thanks very much. 7029 06:02:20,520 --> 06:02:24,240 -Thank you, Walter.
