One time I had an IEP meeting, and my mom was saying that I have PDD; I couldn't say anything, because she would get upset if I did, but the sped staff took it for granted. So they have me registered as PDD-Asperger's-Tourette's.
To narrow it down: Asperger's is a PDD and can exhibit characteristics from Tourette's, I don't believe that someone can have that many disorders, we need to narrow it down.
