Subjective Sleep Characteristics and Cognitive Impairment from Ages 60 to 90+: A Pooled Analysis of Four Prospective Cohorts
Prolonged sleep duration and excessive time in bed were associated with a higher risk of cognitive impairment in adults over 80, independent of comorbidities. These findings highlight somnolence as a potential marker for cognitive impairment in advanced aging, suggesting that tailored sleep monitoring could aid detection.
