Is there be a link between cognitive decline and excessive daytime napping?

A study suggests a bidirectional link between daytime napping and Alzheimer’s disease, indicating that increases in napping duration and frequency could both be a symptom and a contributing factor to cognitive decline. This research, conducted by the Rush University Medical Center and published in Alzheimer’s and Dementia, monitored over 1,400 participants, utilizing wrist-worn sensors to objectively record daytime inactivity. Findings revealed that more extensive napping correlated with worse cognitive outcomes, pointing to potential shared pathophysiological mechanisms between excessive napping and Alzheimer’s progression.
