On a separate note, during the evaluation last year for my 2E son with Asperger's, the evaluator could not decide if his ADHD-like characteristics were just part of the Aspereger's or not. She said that she couldn't tell if he was distracted because he was focusing on his special interests or was just distracted. For example, I can tell when he's not listening to me, but sometimes he will say something that shows he was thinking very deeply about something totally unrelated to homework or chores or whatever.
