“This is an area of investigation where more research is vital to helping us better understand the connection between pollution and the various factors that cause or contribute to Alzheimer’s disease,” Ismail, who also did not work on the study, told Fox News Digital.
“Previous studies, including those presented at the Alzheimer’s Association International Conference in 2019, 2021 and 2025, have shown evidence for connections between exposure to air pollution and other environmental toxins and risk for Alzheimer’s or other dementias.”
“Avoiding exposure to air pollution is a risk factor that may be easier for some people to change than others,” one expert said. (iStock)
