Description

A large team reports 2025 baseline results from the U.S. POINTER trial, which follows older adults at higher risk for memory loss. The study links watch-based sleep measures with brain scans in 454 people. Scans cover brain size, white matter damage, and markers tied to Alzheimer disease.

Sleep length showed a U-shaped link with brain health, so both short and long sleep near six to seven hours went with worse scan results. Sleep length did not track memory test scores or the two Alzheimer markers. The links held mainly in people with no sign of amyloid in the brain.
