The relationship between sleep duration and cognition is established through numerous observational and Mendelian randomization studies {fact:1, fact:8, fact:11} that investigate how variations in sleep length correlate with cognitive performance {fact:7, fact:12}. Scientific literature consistently explores this link across different age groups to determine if sleep duration acts as a predictor for cognitive health or dementia risk {fact:4, fact:5, fact:6}.

measurementThe effect of sleep on cognition is similar across age groups, but older participants (60–73 years) show a smaller variance and range of Executive Function scores related to sleep duration compared to younger participants (38–59 years), with F (262,409, 212,006) = 1.01, 95% CI [1.0017, 1.0181], p = 0.017.
