A recent study from the University of California, San Diego, has uncovered significant differences in how dementia risk factors affect men and women, particularly highlighting that women are more adversely impacted by these factors. Analyzing data from over 17,000 adults, researchers found that women are more likely to experience depression, physical inactivity, and sleep problems, all of which are linked to cognitive decline. In contrast, men exhibited higher rates of hearing loss and diabetes. The findings suggest that common risk factors like hypertension and elevated body mass index have a disproportionately negative effect on women's cognitive health. With women making up nearly two-thirds of Alzheimer's cases in the United States, the study advocates for more personalized prevention strategies that address these sex differences. The researchers call for further investigation into the underlying reasons for these disparities, which may include hormonal influences and healthcare access. This research supports the growing movement towards precision medicine, aiming to tailor interventions to individual characteristics, particularly for women at risk of dementia.
