Wearable accelerometer sleep-wake patterns were linked to later dementia risk in two UK cohorts and modestly improved prediction beyond age and standard risk factors.

Wearable accelerometer sleep-wake patterns were linked to later dementia risk in two UK cohorts and modestly improved prediction beyond age and standard risk factors.

In a large UK Biobank cohort, accelerometer-measured moderate‑to‑vigorous physical activity (100–400 min/week) was associated with lower cardiovascular risk and no excess arrhythmic or cardiomyopathy onset among genotype‑positive phenotype‑
