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.
