Bigbadwool, if you are looking to rule ASD in or out, a psychiatrist probably isn't your best bet. They tend to be very good at selecting and prescribing meds, but not necessarily at diagnosing ASDs.

I'd seek out a developmental pediatrician or neuropsychologist, preferably one who has seen lots and lots of kids on the spectrum, including gifted ones. That is your best bet for teasing out what is autism and what is giftedness and what is something else.

Best,
