PROJECT SUMMARY Early detection of cognitive and functional decline is a major goal of the NIA in its fight against Alzheimer's Disease and Related Dementias (ADRD). Physical, physiological, and cognitive changes associated with ADRD may emerge years prior to clinical manifestations, thus there is an urgent need for novel, cost-effective, noninvasive, and scalable tools to improve detection of ADRD risk. Older adults with cognitive impairment often exhibit changes in movement, sleep, and heart rhythms, suggesting possible shared vascular or neurodegenerative pathways. Emerging research from our group and others links digital signals from movement, sleep, and heart rhythms with brain and cognitive health; however, knowledge gaps remain in the associations among these signals and brain and cognitive health across the cognitive spectrum. In response to NOT-AG-20- 017, this application will directly address these gaps using existing and ongoing/new data collection from wearable technology (7-day accelerometry and 14-day ambulatory electrocardiogram (ECG)), cognitive assessments (neuropsychological battery, adjudicated cognitive diagnosis), and neuroimaging (florbetapir PET for beta amyloid (Aβ), 3T brain MRI for neurodegeneration and white matter disease) from ≥1000 older adults participating in the Atherosclerosis Risk in Communities (ARIC) Neurocognitive Study. We will use novel analytic approaches to integrate movement, sleep, and heart rhythm features and assess their individual and joint associations with brain and cognitive health. Our overarching goal is to identify clinically relevant digital biomarkers that combine movement, sleep, and heart rhythm signals as sensitive indicators of cognitive function, cognitive trajectories, ADRD pathology, and cognitive diagnosis. To this end, this research will inform the future use of wearable devices in large-scale studies, provide novel targets for screening and early detection of ADRD in disease stages during which intervention and treatment are more likely to be effective, and aid in identifying high-risk participants for prevention trials.

项目摘要 早期发现认知和功能下降是NIA在与阿尔茨海默氏症斗争中的主要目标 疾病和相关痴呆症（ADRD）。与ADRD相关的身体，身体和认知变化 可能会在临床表现之前几年出现，因此迫切需要新颖，成本效益， 非侵入性和可扩展工具，以改善ADRD风险的检测。经常患有认知障碍的老年人 表现出运动，睡眠和心律的变化，表明可能共享血管或 神经退行性途径。来自我们小组和其他人的新兴研究与运动的数字信号联系在一起， 睡眠和心律与大脑和认知健康；但是，知识差距仍然存在于协会中 在这些信号，大脑和认知范围内的认知健康中。响应不ag-ag-20- 017，此应用程序将使用现有的和正在进行的/新数据收集直接解决这些差距 可穿戴技术（7天的加速度计和14天心理心电图（ECG）），认知 评估（神经心理电池，调整后的认知诊断）和神经影像学（Florbetapir PET 对于≥1000名老年人的β-淀粉样蛋白（Aβ），3T脑MRI） 参与社区（ARIC）神经认知研究的动脉粥样硬化风险。我们将使用新颖的分析 整合运动，睡眠和心律特征并评估其个人和关节的方法 与大脑和认知健康的关联。我们的总体目标是确定临床相关的数字 将运动，睡眠和心律信号与认知功能的敏感指标相结合的生物标志物， 认知轨迹，ADRD病理和认知诊断。为此，这项研究将为未来提供信息 在大规模研究中使用可穿戴设备，为筛查和早期检测提供了新的目标 在疾病阶段，干预和治疗更有可能有效，并有助于识别 高危参与者进行预防试验。
