UC San Diego Study Finds 13 Dementia Risks Hit Women Harder in 17,000-Adult Analysis

Summary
More than 17,000 U.S. adults in the Health and Retirement Study showed several modifiable dementia risks were tied to steeper cognitive declines in women than in men, UC San Diego researchers reported.
The analysis of 13 established risk factors found hypertension, higher body mass index, hearing loss and diabetes had stronger links to poorer cognition in women, even when some of those conditions were more common in men.
Women also reported several risks more often, including depression at 17% versus 9% in men, physical inactivity at 48% versus 42%, and sleep problems at 45% versus 40%; high blood pressure affected about 60% of both groups.
The findings may help explain why women make up nearly two-thirds of the roughly 7 million Americans living with Alzheimer’s and support sex-specific prevention strategies focused on depression, exercise and cardiovascular health.
Men have higher rates of diabetes and hearing loss, so why do these conditions cause more cognitive damage in women?

Women Face 2x Greater Dementia Risk: New 2026 Study Reveals Modifiable Factors and Urgent Need for Targeted Prevention
Overview
A major study published in May 2026 revealed that women are more severely impacted by modifiable dementia risk factors than men. This discovery highlights the urgent need for targeted prevention strategies focused on women. The research shows that many dementia risk factors, such as depression, low physical activity, and poor cardiovascular health, can be changed, offering clear opportunities for intervention. By addressing these factors, especially in women, it is possible to reduce the overall burden of dementia. This groundbreaking work marks an important step toward more effective and personalized prevention efforts for women.
