I asked the same thing on the Asperger's/Autism forum and they said it is possible to have both disorders. I don't mind having them. It doesn't change who am I and my potential. It is just additional information that I want to have in order to gain insight into my problems.
I remember as a young four year old kid I love to mimic my karate teacher and tease him. I didn't like to obey my teachers, and have thrown temper tantrums when confronted with something I consider unjust.
With respect to autism, I remember I was obsessed with having a string straightened so I could observe it. I liked to observe how straight it was and it satisfied me. But the storm came when the string was curved a little bit by either my parents or other family members. I would scream at the top of my lungs and straighten the string again. I outgrew that quirk, but I can still be obsessive about details in data or in books. I deslike vagueness and perfunctoriness whenever data is presented. I don't want any "scientists found..." No! Which scientists found that datum? Were they experts in that field? Do they even exist?
Stuff like that.
You are the second person that agrees with Asperger's syndrome
