Sleep deficiency is associated with atrophy of the inferior parietal region of the brain, according to a study published online.

The National Institute of Information and Communications Technology (NICT) has revealed, through fMRI-based brain activity analysis, that multiple regions in the human cerebral cortex flexibly ...

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).
