Environmental pollution may contribute to racial/ethnic disparities In Alzheimer’s disease risk

Fine particle pollution may be one reason why Black women have double the risk of developing Alzheimer's than white women, suggests new research. Data shows that older people are more likely to develop dementia if they live in locations with high PM2.5, and African American populations are more likely to live in neighborhoods near polluting facilities. Even when controlling for other risk factors, this study found that Black women still had roughly two times greater a risk of developing Alzheimer's disease than white women, and it also found that they had higher exposure to PM2.5.
