Abstract

Aims: We investigated whether the longitudinal relation between memory complaints and subsequent decline in executive functioning over 6 years differed by leisure activity engagement as major contributor to cognitive reserve in old age.

Methods: We analyzed longitudinal data from 897 older adults (M = 74.33 years) tested on the Trail Making Test (TMT) in two waves 6 years apart. Participants reported information on memory complaints and leisure activity engagement.

Results: There was a significant interaction of memory complaints with leisure activity engagement on latent change in executive functioning. Specifically, only for individuals with less (but not those with greater) leisure activity engagement, memory complaints significantly predicted a steeper subsequent decline in executive functioning across 6 years (i.e., increases in TMT completion time).

Conclusion: The role of memory complaints as an early predictor of decline in executive functioning seems to vary by individuals' cognitive reserve.

认知储备调节记忆抱怨对随后执行功能下降的预测作用。

目的:我们调查了记忆抱怨与随后的执行功能下降之间的纵向关系是否因休闲活动参与作为老年认知储备的主要贡献者而有所不同。方法:我们对897名老年人(M = 74.33岁)的纵向数据进行了分析，这些老年人分两波进行了追踪测试(TMT)，间隔6年。参与者报告了关于记忆抱怨和休闲活动参与的信息。结果:记忆抱怨与休闲活动参与对执行功能的潜在变化有显著的交互作用。具体来说，只有休闲活动参与较少的个体(而不是休闲活动参与较多的个体)，记忆抱怨显著预测了6年内执行功能的急剧下降(即TMT完成时间的增加)。结论:记忆抱怨作为执行功能下降的早期预测因素的作用似乎因个体的认知储备而异。

期刊介绍： This open access and online-only journal publishes original articles covering the entire spectrum of cognitive dysfunction such as Alzheimer’s and Parkinson’s disease, Huntington’s chorea and other neurodegenerative diseases. The journal draws from diverse related research disciplines such as psychogeriatrics, neuropsychology, clinical neurology, morphology, physiology, genetic molecular biology, pathology, biochemistry, immunology, pharmacology and pharmaceutics. Strong emphasis is placed on the publication of research findings from animal studies which are complemented by clinical and therapeutic experience to give an overall appreciation of the field. Dementia and Geriatric Cognitive Disorders Extra provides additional contents based on reviewed and accepted submissions to the main journal Dementia and Geriatric Cognitive Disorders Extra .
