Further Evidence That Air Pollution May Age BrainBack in 2011, we reported on this blog that several studies had shown that exposure to air pollution can harm the brain and even lead to premature death. A new study in over 1,400 women has just been published, highlighting additional findings on air pollution’s deleterious effects on brain function.

Measuring air particulate concentrations, the researchers found that increases in exposure to harmful pollutant particulates corresponded with increases in accelerated mental aging.

The lead author of the study, an associate professor of preventive medicine at the Keck School of Medicine at the University of Southern California, noted that the finding means that “particles in the ambient air are an environmental neurotoxin to the aging brain.”
