Bombay, Shanghai, Delhi, Beijing, New York, London, Los Angeles, Tokyo are some of the most populated cities on earth. It turns out living in these sorts of places may be really bad for your long term brain health. A new study out of the Keck School of Medicine at the University of Southern California indicates that smog may speed the development of atherosclerosis.

Nino Kuenzil, an associate professor of preventative medicine at USC notes: “If confirmed, the public-health relevance would be enormous. Atherosclerosis plays a major role in a broad array of diseases, and almost everybody is regularly exposed to ambient air pollution, 24 hours a day, over a lifetime.”

As I’ve commented on in several earlier posts, the ability of your brain to function well is critically dependent on its blood supply. The better the blood supply, the better your brain will function as you get older. Since atherosclerosis cripples the blood supply to the brain, avoiding atherosclerosis is incredibly important when it comes to maintaining brain power.
