An Early Warning Sign of Alzheimer's May Be Keeping Some Women Up at Night
- New study finds poor sleep linked to more brain tau buildup in older women at high genetic risk for Alzheimer’s.
- Worse sleep linked to poorer visual memory in older, high-risk women, per the study's tests.
- The research focused on 69 women aged 65 or older with varying genetic risk for Alzheimer's.
- No causal link established; authors call for further research before drawing conclusions.
- Researchers suggest improving sleep might help mitigate genetic risk for Alzheimer's.
- The study indicates sleep quality is a modifiable factor that could influence Alzheimer’s risk.
- Research was published in the Journal of Prevention of Alzheimer's Disease.
- The study analyzed sleep quality via self-reports and objective tau measurements in brain regions.
- Experts say misalignment between perceived and actual sleep may signal early symptoms among high-risk individuals.
