项目摘要

ABSTRACT / PROJECT SUMMARY Early onset dementia (EOD) is devastating because it affects individuals at a time of life when they have peak personal and professional responsibilities and are actively contributing to society. Previous work has identified Alzheimer’s disease (AD) and frontotemporal lobar degeneration (FTLD) as the most common causes of EOD. Despite this, most studies of EOD primarily have recruited non-Latinx Whites (NLW). Black and Latinx adults bear a disparate and disproportionate burden of biological and sociocultural vulnerabilities that confer increased ADRD risk in older persons, but the etiologies of dementia in younger members of these Diverse Populations (DPs) are not well understood. Dedicated and well-resourced efforts specifically tailored to study EOD in DPs, including identification of unique risk and resilience factors, are urgently needed. Plasma biomarkers of amyloid, tau and neurodegeneration and remotely collected automated clinical and cognitive assessments could greatly reduce barriers to characterization of EOD in DPs, but most studies evaluating these technologies have been conducted in older NLW. The Biomarker Evaluation in Young Onset Dementia from Diverse Populations (BEYONDD) longitudinal study will address these gaps in knowledge. This five-year longitudinal study will implement a scalable, intensive, and culturally-informed community-engaged research approach to remotely enroll 2,000 adults (<65yrs with 70% DPs and 30% NLW; n=1,700 with cognitive or behavioral impairments [CBI] & n=300 healthy controls) who will complete baseline automated cognitive, clinical, and sociocultural assessments, and blood draws for plasma biomarkers (Aβ42/40, P-tau217 and NfL) in the community, followed by either in-person (n=1,000 with CBI & n=300 healthy controls) or remote (n = 700) longitudinal evaluations. The annual in-person evaluations include “gold standard” clinical evaluations for etiologic diagnosis performed by expert clinicians including neuroimaging evaluations (MRI and amyloid PET). The annual remote evaluations will rely on automated tools. The study aims to: (1) Compare the etiology, severity, and cognitive and biomarker (plasma biomarkers and amyloid PET) profiles of EOD across ethnocultural groups (Black, Latinx and NLW); (2) Examine the effects of biological, psychological and sociocultural factors on EOD and resilience (resistance to EOD despite biological risk) outcomes across ethnocultural strata; (3) Validate plasma biomarkers and cognitive markers collected in the community by comparing the diagnostic accuracy of plasma Aβ42/40, P-tau217, and NfL versus “gold standard” clinical diagnosis and neuro-imaging biomarkers across ethnocultural groups, and evaluating the added value of remote cognitive assessments and clinical metabolic tests to plasma biomarkers’ diagnostic accuracy. Eligible participants will be co-enrolled in ongoing longitudinal ADRD studies focused on EOD while the rest will return for longitudinal assessments through BEYONDD. This project brings together a diverse team of leading scientists in EOD and brain health disparities, private and public stakeholders, and diverse community-based partner organizations, to create new resources to promote inclusive research in EOD.
摘要/项目总结 早发性痴呆(EOD)是毁灭性的,因为它影响个人在生命的时候,当他们有高峰期 个人和职业责任,并积极为社会做出贡献。以前的工作已经确定 阿尔茨海默病(AD)和额颞叶变性(FTLD)是EOD最常见的原因。 尽管如此,大多数爆炸物处理研究主要招募非拉丁裔白人(NLW)。黑人和拉丁裔成人 在生物和社会文化脆弱性方面, 老年人的ADRD风险,但这些不同人群中年轻成员的痴呆症病因 (DPs)并没有得到很好的理解。专门为研究流离失所者的爆炸物处理问题作出了专门的、资源充足的努力, 包括确定独特的风险和复原力因素。淀粉样蛋白的血浆生物标志物, tau蛋白和神经退行性变以及远程收集的自动化临床和认知评估, 减少对确定爆炸物处理在发展中国家的特点的障碍,但大多数评估这些技术的研究都是 在旧的NLW中进行。不同人群青年痴呆的生物标志物评价 (BEYONDD)纵向研究将解决这些知识差距。这项为期五年的纵向研究将 实施可扩展的,密集的,文化知情的社区参与的研究方法,以远程 入组2,000名成人(<65岁,70% DP和30% NLW; n= 1,700名认知或行为障碍[CBI]) & n=300名健康对照),他们将完成基线自动认知、临床和社会文化 评估,并在社区抽血检测血浆生物标志物(Aβ42/40、P-tau 217和NfL),然后 无论是在人(n=1,000与CBI和n=300健康对照)或远程(n = 700)纵向评价。的 年度亲自评估包括由以下人员进行的病原学诊断的“金标准”临床评估: 专家临床医生,包括神经影像学评价(MRI和淀粉样蛋白PET)。年度远程评价将 依靠自动化工具。本研究的目的是:(1)比较病因、严重程度、认知和生物标志物 (血浆生物标志物和淀粉样蛋白PET)的EOD跨民族文化群体(黑人,拉丁裔和NLW)的概况;(2) 研究生物、心理和社会文化因素对爆炸物处理和复原力(抵抗 EOD(尽管存在生物学风险)在民族文化阶层中的结果;(3)血浆生物标志物和认知功能 通过比较血浆Aβ42/40、P-tau 217和NfL的诊断准确性, 与跨民族文化群体的“金标准”临床诊断和神经成像生物标志物相比, 评估远程认知评估和临床代谢测试对血浆生物标志物的附加值 诊断准确性。符合条件的受试者将共同入组正在进行的纵向ADRD研究,重点是 爆炸物处理处,其余人员将通过BEYONDD返回进行纵向评估。该项目汇集了一个 爆炸物处理和脑健康差异方面的领先科学家、私人和公共利益相关者组成的多元化团队, (c)与各种社区伙伴组织合作,创造新的资源,促进爆炸物处理方面的包容性研究。
