The Opioid Epidemic-Pollution and Dementia

Caleb Finch, PhD, ARCO/William F. Kieschnick Professor in the Neurobiology of Aging at the University of Southern California's Leonard Davis School of Gerontology led a study that found that tiny particles that pollute the air—the kind that come mainly from power plants and automobiles—may greatly increase the chance of dementia and Alzheimer’s disease. He said his research indicates that air pollution could be responsible for about 21 percent of all dementia cases.
