"Air Pollution's Link to Dementia and Alzheimer's Disease Risk"

Research suggests that air pollution from traffic, specifically fine particulate matter known as PM2.5, is linked to higher levels of amyloid plaques in the brains of individuals, which are associated with Alzheimer's disease. The study conducted in Atlanta found that even those not genetically predisposed to dementia could be significantly affected by air pollution. The findings highlight the potential harm caused by road traffic pollution and its impact on brain health, particularly for those living near busy roads.
