Air pollution may cause more than just lung disease: New research suggests that if tiny particles in the air from power plants and cars are inhaled, they might also invade the brain, increasing the risk for dementia.
"Although the link between air pollution and Alzheimer's disease is a new scientific frontier, we now have evidence that air pollution, like tobacco, is dangerous to the aging brain," said study co-senior author Caleb Finch. He's with the University of Southern California's (USC) Leonard Davis School of Gerontology.
