A study from the University of California San Diego School of Medicine, published in Biology of Sex Differences, analyzed data from over 17,000 middle-aged and older adults to examine sex-based differences in dementia risk. The research found that women carry a disproportionately higher burden of certain modifiable dementia risk factors compared to men. Furthermore, women appear to show greater cognitive vulnerability to these risk factors, meaning the same risk exposures may produce stronger negative effects on cognitive function in women than in men.
Why it matters
These findings suggest that dementia prevention strategies may need to be tailored by sex, with women potentially benefiting from earlier and more targeted interventions targeting modifiable risk factors. Understanding these biological and epidemiological differences could help reduce the overall prevalence of dementia, which already affects women at higher rates globally.
Researchers from the University of California San Diego School of Medicine have found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function. The study, which analyzed data from more than 17,000 middle-aged and older adults, is published in Biology of Sex Differences.
