Sleep-Wake Patterns Predict Dementia Risk, With 1 Measure Linked to 43% Higher Odds

Summary
A UK Biobank cohort followed for about eight years found accelerometer-derived sleep-wake cycle patterns were associated with future dementia, with one component tied to a 43% higher incident risk.
JAMA Neurology researchers said adding those objective sleep-activity measures to models already using age, lifestyle and clinical factors modestly but significantly improved prediction.
Whitehall II data replicated the associations, strengthening evidence that the link was not limited to a single cohort.
The study suggests wearable monitoring could become a scalable early-identification tool, with predictive value comparable to genetic markers such as APOE status.
