Abstract

Background and objective: Discrepancies between objective and subjective evaluations of sleep efficiency have been observed in individuals with pathological and healthy aging. Objective sleep evaluation using actigraphy has been proposed as a potential tool for the clinical assessment of mild cognitive impairment.

Methods: Habitual sleep at home was evaluated using actigraphy (objective measure) and sleep diaries (subjective measure) in 45 participants (between 28- and 72-years-old). Participants were divided into four groups by age and by diagnosis (mild cognitive impairment and Alzheimer's disorder). Cognitive and sleep measures were analyzed for comparisons and correlations.

Results: Significant discrepancies between objective and subjective sleep efficiency were observed in healthy and pathological ages. The MCI group showed the lowest sleep efficiency compared to other groups. Correlation analysis revealed a significant relationship between cognitive impairments and sleep efficiency in MCI and AD groups.

Conclusions: Objective sleep evaluation, with a particular focus on sleep efficiency, should be considered as a potential marker for MCI.

主观与客观睡眠评价的差异：轻度认知障碍的潜在标志。

背景与目的：在病理性和健康衰老个体中观察到客观和主观睡眠效率评价的差异。利用活动描记仪进行客观睡眠评价已被提出作为轻度认知障碍临床评估的潜在工具。方法：采用活动记录仪（客观测量）和睡眠日记（主观测量）对45名年龄在28 ~ 72岁之间的家庭习惯性睡眠进行评价。参与者根据年龄和诊断（轻度认知障碍和阿尔茨海默病）分为四组。对认知和睡眠测量进行了比较和相关性分析。结果：客观睡眠效率与主观睡眠效率在健康年龄和病理年龄之间存在显著差异。与其他组相比，轻度认知障碍组的睡眠效率最低。相关分析显示MCI组和AD组认知障碍与睡眠效率有显著关系。结论：客观的睡眠评估，特别关注睡眠效率，应被视为轻度认知损伤的潜在标志。
