Women's Dementia Risk May Be Shaped by These Key Factors, Study Finds
- A large observational study of 17,182 adults links sex-specific dementia risk to several factors, with some impacting women more than men.
- Depression, physical inactivity, and sleep problems were more common in women in the study.
- Some risk factors reduced cognition more in women, notably high blood pressure, hearing loss, and diabetes.
- Higher BMI was linked to poorer cognition in women in their 50s and 60s, but not in older ages.
- Education and total cholesterol showed positive associations with cognition, suggesting potential protective roles.
- The study cautions that observations do not prove cause and effect and calls for longer-term analysis.
- Researchers emphasize sex should be treated as a key variable in dementia research to tailor prevention.
- Alzheimer's affects about one in nine US adults aged 65 and older, with two-thirds of cases in women.
