背景：睡眠对最佳认知功能至关重要，但随着年龄的增长，认知障碍和睡眠问题都会增加。纵向，以人群为基础的研究可以用来调查睡眠和cognition.Methods之间的时间关系：共2012认知未受损的个人65岁及以上的MRC认知功能和老龄化研究（CFAS）。他们回答了自我报告的措施，包括：失眠症状和发病年龄，夜间觉醒，打鼾，睡眠开始潜伏期，午睡，白天嗜睡和夜间睡眠持续时间。认知能力通过简易精神状态检查进行测量。结果：研究发现，在基线时白天小睡与2年和10年认知能力下降的风险较低有关，
Background: Sleep is critical for optimal cognitive function, but as we age both cognitive impairment and sleep problems increase. Longitudinal, population-based studies can be used to investigate temporal relationships between sleep and cognition.Methods: A total of 2012 cognitively unimpaired individuals 65 years and over were drawn from the MRC Cognitive Function and Ageing Study (CFAS). They answered self-reported measures including: insomnia symptoms and age of onset, night time wakings, snoring, sleep onset latency, napping, daytime sleepiness and duration of night time sleep. Cognition was measured via the Mini-Mental State Examination.Results: It was found that daytime napping at baseline was associated with a lower risk of cognitive decline at two and 10 years, and that obtaining
