To find out more, environmental health researcher Yanling Deng of Emory University, Georgia, and her and colleagues, examined data on more than 27.8 million U.S. Medicare recipients aged 65 years and older from 2000 to 2018.

The researchers looked at individuals’ air pollution exposure level and whether they developed Alzheimer's disease, while emphasizing the role of other chronic conditions.

They found that greater exposure to air pollution was associated with an increased risk of Alzheimer’s disease, and that association was slightly stronger in individuals who had experienced a stroke, noting that chronic conditions had little additional impact.
