as i posted above, this is false. it's my only soapbox about autism, because the numbers do not support it, but people are misinformed and i find it bad taste to assume things and not have numbers to support it.
about halfway down, when it says,"better diagnosis?"
"some have suggested that autism is just being better diagnosed today versus ten years ago and that many cases of mental retardation are now being coded as autism. this would also assume that the experts diagnosing autism before did not know what they were doing.this is not true. autism is the only disorder dramatically on the rise while mental retardation, down syndrome and cystic fibrosis remain relatively the same.a january 2009 uc mind institute refutes this notion.
