A team of researchers found there is a possible molecular connection between air pollution and an increased risk of developing Lewy body dementia. The study builds on a decade of research linking exposure to fine particulate air pollution (PM_2.5) -- from industrial activity, residential burning, wildfires, and vehicle exhaust—to a higher risk of developing these diseases. The findings add to a growing body of evidence indicating how environmental factors may trigger harmful protein changes in the brain that lead to neurodegeneration.
