Smog in the brain: Dirty air speeds Alzheimer’s decline

Scientists have discovered that even short-term exposure to polluted air can speed up Alzheimer’s, worsening toxic protein buildup in the brain and accelerating memory loss. The research connects fine particulate matter (PM2.5) from sources like smoke and traffic directly to faster cognitive decline.

Air pollution has been tied to Alzheimer’s disease. Here’s what you need to know

‘Air pollution doesn’t just increase the risk of dementia — it actually makes Alzheimer’s disease worse,’ Dr. Edward Lee says

Exposure to Air Pollution Linked to Alzheimer’s Disease

Research from the University of Pennsylvania shows a link between more severe dementia and Alzheimer’s disease and high exposure to air pollution. Using autopsy data from individuals with Alzheimer’s disease or other forms of dementia, as well as controls, the researchers showed increased exposure to air pollution specifically led to worsened symptoms and brain pathology. “Air pollution has been suggested to be an environmental risk factor for d…
