Introduction:
Air pollution causes harmful physical changes in the brain

Now comes information from another Ohio State University study that long-term exposure to air pollution can literally change your brain. And as you might expect, these physical changes in the brain are not beneficial. They areassociated with learning and memory problems and even depression.

The new study, just published online in the journal Molecular Psychiatry is the first long-term research to show the negative impact of air pollution on the brain, according to Laura Fonken, lead author of the study and a doctoral student in neuroscience at Ohio State University. "The results suggest prolonged exposure to polluted aircan have visible, negative effects on the brain, which can lead to a variety of health problems," Fonken said in a statement to the media.

In earlier studies in mice, researchers in Ohio State University's Davis Heart and Lung Research Institute (who also collaborated with Fonken and colleagues on the new research project) found that fine air particulate matter causes widespread inflammation inthe body -- leading to a heightened risk for diabetes and obesity, as well as hypertension. Their extended research on air pollution's impact on the brain adds more disturbing evidence that bad air is bad for thinking, too.

"The more we learn about the health effects of prolonged exposure to air pollution, the more reasons there are to be concerned," stated Randy Nelson, co-author of the studyand professor of neuroscience and psychology at Ohio State, in the press statement.

For the new study, lab mice were exposed five days a week to either filtered air or polluted air for six hours a day. The polluted air contained the same type of pollution created by cars, factories and natural dust and included very fine particulate matter -- particles so minute they are only about 1/30th of...
