Description
Summary:	Highlights • Sleep and the circadian rhythm impact cognitive functioning. • Sleep and 24-h activity rhythms were measured with actigraphy in 1723 persons. • Cognitive functioning was assessed with five different neuropsychological tasks. • Persons with a longer sleep-onset latency scored worse on memory and verbal tasks. • Persons with disturbed rhythms scored worse on executive function and speed tasks.
