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).

"We have come to understand that sleep is really intertwined with the neurological processes driving Alzheimer's and similar dementias," said Dr. Alberto Ramos, research director of the Sleep ...
