Several parts of the aging brain are an important target of neurotoxic effects induced by long-term exposure to fine particles in the ambient air.

Older women who lived in places with higher air pollution had significantly reduced white matter in their brain. These findings suggest that ambient particulate air pollutants may have a deleterious effect on brain aging.
Lead author Dr. Jiu-Chiuan Chen said, "Our study provided the convincing evidence that several parts of the aging brain, especially the white matter, are an important target of neurotoxic effects induced by long-term exposure to fine particles in the ambient air."
The study appears in Annals of Neurology.
