Studies: Air pollution linked to brain damage

"Scientists in 2004 studied the brain tissue of children and young adults in Mexico who had died of accidents and were stunned by what they found -- a discovery that rocked the world of neuroscience and has gone largely untested until now.
Almost all the young people had evidence of Alzheimer's protein plaques scattered throughout their brain tissue.
The only factor linking one case to another was air pollution in Mexico City, which led scientists at the time to hypothesize that smog might be a trigger of Alzheimer's disease and that the mind-robbing damage might start early in life."
