Heck, I say "go for it". Especially with family history like that.
My son saw Dr. Tony Attwood and he sure explained a lot about myself at the same time. I'm very, very thankful that he lives near here. Up until seeing him it had been years of denial by other doctors and years of misdiagnoses and years of unnecessary treatments and years of suggestions that he'd need residential care and years of missed support and guidance in school. Years! Phooey to them.

I found a list somewhere with knowledgeable doctors or psychologists on it. I'll go find it and post it when I do. Are you in USA or elsewhere?

Sometimes it can be a real revelation to finally talk with someone who understands why a person has done or does certain things. By the time we reach middle age people tend to adapt pretty well, but there can always be those nagging questions and self-doubts.

If you're wanting to learn more for the time being, you might find some suitable sites online if you just search "Asperger's Syndrome and adult issues".

Edited to add: This is one of the lists I kept.

Some are Pediatric practices, but others see Adults. I will post the other one for adults if I can find it.

OK, more here...

p.s. I can't personally vouch for any of them. The second one has different people listed than the first. Only one I know is Tony Attwood.
