The prevalence of subjective sleep and cognitive complaints increases with age. The purpose of this study was to investigate the link between subjective cognitive and sleep complaints in a population aged 65.analysis of a cohort of 1011 subjects aged 65 years old at time of inclusion.Older people underwent a cognitive tests battery and a nocturnal polygraphy recording. Subjective cognitive difficulties were scored on the McNair and Kahn Scale. Subjective sleep complaints were evaluated according to the St. Mary's Hospital Sleep Questionnaire and the Epworth Sleepiness Scale score.In a 65 years old population, an association between subjective cognitive difficulties and poor sleep quality was observed. This remained significant after adjustment on gender, depression score, anxiety, educational level, medication intake, Apnea/Hypopnea index, Body Mass Index and Mini-Mental State Examination (OR = 2.1; p = 0.0002). Similar significant association was demonstrated between subjective cognitive difficulties and daytime sleepiness (OR = 2.6; p = 0.0007).There was a significant association between subjective cognitive and sleep complaints, and daytime sleepiness in our population of older people.
