项目摘要
DESCRIPTION (provided by applicant): There is a considerable amount of social and behavioral data that is correlational in nature suggesting that individuals who are deeply engaged in social and intellectual activities in mid and late adulthood show delays in normal age-related cognitive decline as well as in the onset of dementia. The present project entitled "Active Interventions for the Mind" is designed to provide one of the first experimental tests of the impact of sustained engagement on cognition in late adulthood. In the AIM project, we distinguish between productive engagement (engaging activities that require sustained activation of cognitive resources such as working memory, reasoning, and long-term memory, often in a social setting) and receptive engagement (engagement that relies primarily on existing knowledge and social interactions). Based on a successful pilot program, we propose to enroll older adults in intensive productive engagement conditions (e.g., learning to quilt or to use digital photography) a receptive engagement condition (e.g., participating in a primarily social program where leisure activities have low resource requirements), or control conditions (Wait-List or Placebo Control where low level cognitive activities are performed at home). All subjects except Wait-List controls will engage in activities 15 hours per week over a period of 16 weeks. We will contrast cognitive, affective and neural function in the productive engagement group with the other conditions, and hypothesize that sustained engagement in conditions that are both intellectually and socially stimulating over this time period will facilitate cognition in older adults relative to a wait-list control. Moreover, because learning a new skill and making new social contacts may permanently impact participants' daily behavior, the impact of the engagement will be assessed initially as well as a year later. Both behavioral and neural measures of cognitive change will be assessed, providing considerable insight into mechanisms of change. Subjects will be characterized thoroughly in terms of behavioral tests of cognitive function, measures of brain structure through structural imaging, and measures of brain function through functional neuroimaging, as well as in terms of psychosocial variables.. The AIM project represents one of the first systematic attempt to change and then measure older adults' lifestyle for a sustained period in an attempt to understand lifestyle factors that contribute to cognitive and neural vitality in late adulthood, much as we understand lifestyle factors that contribute to good cardiovascular health.
描述(由申请人提供):大量的社会和行为数据在本质上是相关的,表明在成年中后期深度从事社会和智力活动的个体在正常的年龄相关的认知能力下降以及痴呆症的发病方面表现出延迟。目前的项目题为“积极干预心智”,旨在对持续参与对成年后期认知的影响进行首批实验测试之一。在AIM项目中,我们区分了生产性参与(需要持续激活认知资源的参与活动,如工作记忆、推理和长期记忆,通常在社会环境中)和接受性参与(主要依赖于现有知识和社会互动的参与)。基于一个成功的试点项目,我们建议将老年人纳入密集的生产性参与条件(例如,学习拼布或使用数码摄影)、接受性参与条件(例如,参与休闲活动资源需求低的主要社交活动)或控制条件(等待名单或安慰剂控制,在家中进行低水平的认知活动)。除等候名单控制组外,所有受试者将在16周内每周参加15小时的活动。我们将对比生产性参与组与其他条件下的认知、情感和神经功能,并假设在这段时间内,在智力和社会刺激的条件下持续参与,相对于等待名单控制,将促进老年人的认知。此外,由于学习一项新技能和建立新的社会联系可能会永久地影响参与者的日常行为,因此参与的影响将在最初和一年后进行评估。认知变化的行为和神经测量都将被评估,为变化的机制提供相当大的见解。通过认知功能的行为测试,通过结构成像测量大脑结构,通过功能神经成像测量大脑功能,以及根据社会心理变量,对受试者进行彻底的表征。AIM项目是第一次系统地尝试改变老年人的生活方式,然后在一段持续的时间内测量老年人的生活方式,试图了解影响成年后期认知和神经活力的生活方式因素,就像我们了解有助于良好心血管健康的生活方式因素一样。
