It's funny how so many people were diagnosed with 2 or more mutually exclusive disorders like PDD NOS and Asperger's or AS and a personality disorder ect. Also, Tyrion and I were officially diagnosed with a disorder that doesn't officially exist! -NVLD. Callista, you almost have a collection of all the disorders in the PDD category of the DSM IV TR (atleast you can say you were diagnosed with them all at one point).

The only one you're missing is Childhood Dintegrative Disorder. They're changing it in a month, though, anyway. I guess it's a good argument for why they need to change it: they can't distinguish between the different PDD's. They really should add NVLD too.
I think it's more that their diagnosis was shifted from PDDNOS to autism or Asperger's upon further evaluation.
