Study Links Poor Sleep to Memory Issues in Older Women

A study of 69 women aged 65 and older suggests poor sleep quality is linked to weaker visual memory in those with a high inherited risk of Alzheimer’s.

Brain scans of participants revealed that those with higher genetic risk and poor sleep patterns showed increased build-up of harmful substances associated with Alzheimer’s disease.

Published in the August 2026 issue of The Journal of Prevention of Alzheimer’s Disease, the research emphasizes sleep as a critical factor in healthy aging.
