A recent study in the Journal of Clinical Sleep Medicine explores how specific sleep patterns relate to brain health and early signs of Alzheimer’s disease. Researchers followed 270 participants, using polysomnography and brain imaging to examine sleep stages and brain volume changes. The results indicate that reductions in slow-wave sleep and REM sleep correlate with brain regions commonly affected early in Alzheimer’s, suggesting sleep quality could be a modifiable risk factor.
