Research Abstract

Recent epidemiological studies have reported physical activity or sleep duration were associated with cognitive decline and brain's natural capacity for plasticity. However, it is not clear the effects of sleep duration on the brain areas in the elderly. The purpose of this study is to evaluate the relationships between self-reported habitual sleep duration and brain's natural capacity / cognitive function among elderly subjects. We analyzed cross-sectional data from a community-based Comprehensive Geriatric Assessment (CGA) conducted among elderly Japanese subjects living in Tsurugaya district. The correlation between self-reported habitual sleep duration and brain gray matter volumes of all region including the hippocampus was not significant (p<0.05). The significant relationship was not found for the cognitive function score
