New research reveals that lower proportions of specific sleep stages are associated with reduced brain volume in regions vulnerable to the development of Alzheimer's disease over time.

These findings provide some evidence that reduced slow wave sleep (SWS) and rapid eye movement sleep (REM) may contribute to brain atrophy, thereby increasing the risk of Alzheimer disease (AD).
