flag Poor sleep, especially less deep and REM sleep, may increase Alzheimer's risk, study suggests.

flag Recent research links poor quality sleep, especially less deep sleep and REM sleep, to an increased risk of Alzheimer's disease. flag The study, involving 270 participants, found that less time spent in these sleep stages was associated with smaller volumes in critical brain regions, particularly the inferior parietal region, linked to early Alzheimer's changes. flag The findings suggest that improving sleep could be a way to reduce Alzheimer's risk, though more research is needed to confirm the link.
