Associations between cognitive function, actigraphy‐based and self‐reported sleep in older community‐dwelling adults: Findings from the Irish Longitudinal Study on Ageing

Abstract

Self-reported long sleep duration was consistently associated with worse cognitive performance across multiple domains. Marginal associations between cognition and both actigraphy-based sleep and self-reported sleep problems were also apparent. These results further affirm poor sleep as a risk factor for cognitive impairment.
