I think what you are officially diagnosed with depends where you are and what for. For me I have an offical DX of PDD-NOS because that is what the government requires in order for me to qualify for disability support pension. The Guy who DX'ed my is one of the top guys around here, so he knows what he is doing. He'll pretty much do anything in order for you to get what you need, re government assistance, schooling etc. He basicly said that the only time he wont bend the truth in order for you to get what you want is when it comes to the court system. Cool guy.
