Poor Sleep Linked to Alzheimer's Risk | JQJO

New research links poor sleep quality to reduced brain volume in areas vulnerable to Alzheimer's. A study of 270 participants found that lower amounts of slow-wave and REM sleep correlated with smaller brain volumes, particularly in the inferior parietal region. This association remained even after accounting for other health factors. The findings suggest sleep quality could be a modifiable risk factor for Alzheimer's, emphasizing the importance of restorative sleep for brain health. Further research is needed to confirm the causal link.
