Long-term exposure to air pollution has been linked to a higher risk of depression. Additionally, suicide risk is measurably higher on days when PM10 levels have been high for over three days following less polluted periods. Read More
Older women exposed to higher levels of air pollution were more likely to experience greater memory decline and Alzheimer's-like brain atrophy compared with those exposed to cleaner air. Read More
Poor air quality has been linked to higher rates of bipolar disorder and major depressive disorder. Exposure to air pollution during the first ten years of like is also associated with a more than two-fold increased risk of schizophrenia and personality disorders. Read More
Maternal exposure to higher levels of air pollution is associated with lower IQ scores in their children. For those whose mothers were in the highest 10% of exposure had IQ score that were, on average, 2.5 points lower than those whose mothers were in the lowest 10%. However, higher maternal folate levels appear to neurtralize the effect of high pollution exposure on offspring. Read More
