NeurologyAdvisor: A cross-sectional study found that sleep duration may affect episodic memory, according to study findings published in the Journal of Sleep Research.

Sleep is an important component to healthy aging and cognitive function. Although this link has been well-established, it remains unclear what specific components of sleep and cognition are related. The objective of the current study was to examine cross-sectional and prospective associations between self-reported sleep and cognitive function in middle-to-older aged adults in the United States.

These data suggested that people with long sleep durations may have lower cognitive performance. This association likely affects men and women differently. Additional studies are needed to confirm these findings.
