Smog in the Brain: Dirty Air Speeds Alzheimer’s Decline
Researchers found pollution exposure was linked to cortical thickness changes equal to about 13 months of aging for PM2.5 and three months for NO2.

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.
Researchers analyzed brain images of adults without dementia and found differences in cortex thickness associated with exposure to PM2.5 and nitrogen dioxide.

Air Pollution May Reshape Alzheimer’s-Vulnerable Brain Regions—But the Pattern Changes With Age Common outdoor air pollutants may be associated with structural changes in brain regions that are particularly vulnerable to Alzheimer’s disease, according to a new observational study led by researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute at the Keck School of Medicine of USC. The research, published in NeuroToxico…
