One is the inferior frontal gyrus ... when you have those verbal representations." The brain's prefrontal cortex shrinks as a part of normal aging; with Alzheimer's disease, the frontal cortex ...

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).
