PROJECT SUMMARY Approximately 16 million Americans serve as family caregivers for a person with Alzheimer's disease and related dementias and this care can take a physical and emotional toll. Understudied is how this informal care can affect caregiver cognitive health and associated daily sleep and activities, all of which are modifiable health behaviors. Engaging in personally meaningful, and cognitively stimulating activities can benefit cognitive and sleep health among dementia care dyads. Despite the importance of activity engagement for cognitive functioning and sleep quality, existing assessment of activities and outcomes is often self-reported asynchronously at global levels. Contemporaneous assessment of activities, sleep, and cognitive health and well-being would significantly advance research in this area by 1) conducting objective assessments on daily sleep and activities within a dyadic context, 2) determining how the social context of caregivers' assistance for the individuals with dementia's activity engagement moderates the associations between cognitive health and well-being, and daily sleep and activities, and 3) determining how a chronic stress biomarker, hair cortisol concentration, mediates the activities- and sleep-cognition associations in naturalistic settings. The proposed mentored career development award combines a rigorous program of research, mentorship, and didactics to facilitate the candidate's growth toward an overall career goal of becoming an independent investigator focused on informing the design of interventions for aging caregiving dyads with complex care needs including dementia to improve both partners' well- being. The training aims will assist the candidate in acquiring: 1) grounded knowledge of clinical care and educational needs among care dyads relating to neurocognitive assessment, functioning, and understanding the clinical aspects of dementia, 2) specialized skills in the assessment, analysis, and interpretation of daily sleep and activity measures and the biological measure of chronic stress that link to the dementia care situation and specifically to caregiver cognitive health and well-being, and 3) expertise in the application of intensive repeated measures designs that will generate novel insights on proximal risk and protective factors for poor caregiver outcomes within the dyadic context. The training aims seek to further develop the candidate's expertise as an interdisciplinary researcher in the area of later-life dementia family caregiving and align closely with the research aims to: 1) quantify caregiver daily sleep characteristics with actigraphy and determine their associations with caregiver cognitive functioning and well-being; 2) quantify caregiver daily activity characteristics with accelerometry and determine their associations with caregiver cognitive functioning and well-being; and 3) To characterize how caregiver assistance for PLwD's activity engagement moderates, and how hair cortisol concentration mediates associations of sleep➔cognition and activities➔cognition. An integrated, biopsychosocial approach to identifying protective factors that promote resilience and reduce harmful risk factors will inform the development of future targeted caregiver interventions in the dyadic context for a highly vulnerable aging population.

项目概要 大约 1600 万美国人担任阿尔茨海默病及相关疾病患者的家庭护理人员 痴呆症和这种护理可能会造成身体和情感上的损失，但这种非正式护理对护理人员的影响尚未得到充分研究。 认知健康以及相关的日常睡眠和活动，所有这些都是可改变的健康行为。 对个人有意义且刺激认知的活动可以有益于痴呆症护理中的认知和睡眠健康 尽管活动参与对于认知功能和睡眠质量很重要，但现有的评估 活动和成果通常在全球层面异步进行自我报告，同时对活动进行评估。 睡眠、认知健康和福祉将通过以下方式显着推进该领域的研究：1）进行客观 在二元背景下评估日常睡眠和活动，2) 确定护理人员的社会背景如何 对痴呆症患者的活动参与的帮助可以调节认知健康之间的关联 和幸福感、日常睡眠和活动，以及 3) 确定慢性压力生物标志物——头发皮质醇 注意力，调解自然环境中的活动和睡眠认知关联。 职业发展奖结合了严格的研究、指导和教学计划，以促进候选人 朝着成为一名独立调查员的总体职业目标成长，专注于为设计提供信息 对具有复杂护理需求（包括痴呆症）的老年护理二人进行干预，以改善伴侣双方的健康状况 培训目标将帮助候选人获得：1）临床护理和教育的基础知识。 护理双人组中与神经认知评估、功能和理解临床方面相关的需求 痴呆症，2) 评估、分析和解释日常睡眠和活动测量的专业技能以及 与痴呆症护理情况尤其是护理人员认知健康相关的慢性压力的生物学测量 和福祉，以及3）应用密集重复测量设计的专业知识，这将产生新颖的见解 培训目标旨在研究二元背景下护理人员结果不佳的近端风险和保护因素。 进一步发展候选人作为晚年痴呆症家庭领域跨学科研究人员的专业知识 护理并与研究目标密切结合，旨在：1）通过体动记录仪量化护理人员的日常睡眠特征 并确定看护者与认知功能和幸福感的关联；2) 量化看护者的日常活动； 加速度测量特征，并确定它们与护理人员认知功能和幸福感的关联； 3) 描述护理人员对 PLwD 活动参与度的帮助如何调节，以及头发皮质醇如何调节 注意力介导睡眠➔认知和活动➔认知的关联。 确定可促进复原力和减少有害风险因素的保护因素的方法将为 在二元背景下为高度脆弱的老龄化人口制定未来有针对性的护理干预措施。
