not my impression. i asked my psychologist about it and he said "no, it won't be that - that's a thing that's diagnosed in children i think. someone would've diagnosed you by now".
I asked if it would have been known back when i was a child, and he said "yeah - you weren't exactly born in the 50's."
Next week he came back and said he'd found out that it could sometimes get diagnosed in adulthood, but he didn't think i had it.
Also, I'd been to another (nhs) psychiatrist once, before i'd heard of AS, thinking i might have ADHD. He told me that condition had been made up by pharmaceutical companies to sell drugs.
There are places with better understandings than that I think, but it seems to vary around location, doctor, private/nhs.
I'm self dx-ed by the way, but am pretty sure of it, having met and compared experiences with several diagnosed aspies. Can't really see the point for met to get a professional dx now
