He definitely sounds like he's gifted.

Seeing as how you already have 2 diagnoses and are concerned about a 3rd, I'd recommend trying to find a Neuropsychologist who can do a full battery of tests, including IQ.

Our NeuroPsych likes to see the kids and re-test them every couple of years to make sure they are making expected progress as well. I'm going to schedule DS9 for next year for his second go-round.
