Washington Post: September Medical Mystery

Washington Post::  September Medical Mystery
The September installment of the "Medical Mysteries" series is out in today's Washington Post, with an interesting story about a young boy's sudden, inexplicable development of anxiety and obsessive-compulsive tics.  As with the previous illustrations in the series, the design was to convey the symptoms as well as the culprit, which in this case interestingly enough was an autoimmune neuropsychological disorder's (PANDAS) response to to a bacterial strep infection.
