Autism is real.

--The brain is mildly defective in a way, and the amount of effected tissue determines the autism.
Asperger's Syndrome is real. I have it, and it was NOT diagnosed by a single idiot with his head shoved so far up his ass that he could see through his mouth. It was diagnosed by the entire psychiatric ward at Vanderbilt Psychiatric Hospital in the Nashville area over a period of three days. It is a redistribution of brain cell allocation, as illustrated by
THIS CHART. There are many portions of the brain which are smaller than in the average person, but there are also a few particularly important areas which have been enlarged.
Clinical depression is real -- A Serotonin imbalance causes a lack of clear thinking, causing all things to seem worse than they truly are.
Attention Deficit Disorder is real as well, but many dumbass psychologists seem to be mistaking that for boredom.
