My brother is autistic, one in 150 or one in 70 boys.
20 years ago or so it was one in 25,000. A strong part of me feels we as a society have done something WRONG and we have altered these children in some way. Im not a doctor but I have seen a lot of them in the last few months and I can tell you they dont know what autism is either. My mother knows a women who's daughter was the most severe case of autism her peadiatrition had seen, self harm rocking tantrums that lasted 3 hours and with intensive therapy she is indistinguishable from 'typical' kids at the age of 13.
