Brain Shrinkage, Memory Problems, Depression Linked to Air Pollution Chemicals

Two separate scientific studies have revealed some sobering news about the link between air pollution chemicals and serious brain harm.  In the first study, higher exposures to air pollution chemicals were associated with increased depressive symptoms and subsequent memory decline. In the second study, people who had higher levels of air pollution exposure had more brain shrinkage–the kind of shrinkage commonly seen in people suffering from Alzheimer’s disease.
