Like WhittenKitten, I got to the point at which I was informed it is likely that I have AS. I never took it beyond that point to make anything official. That said, my son was later diagnosed with Asperger's and others in my family have been diagnosed with Autism and Asperger's. Basically, we are a family on the spectrum.
The issue of official v. unofficial diagnosis comes up quite often here, and I immediately think of Tourette's syndrome which also runs in my family. We have had two "official" diagnoses of TS in my extended family, but it doesn't take a doctor to identify the other ticcing machines in my family. Should I tell them they don't "officially" have TS or tics and therefore are just like everyone else?
I do agree that some people who post here clearly do no have AS, but for most I cannot tell.
This being the Internet, we will never ferret out who does and does not have AS. Anyone can alter their identity and traits in their profile or postings. I can't be sure that "garyww" is who he says he is (for the record I trust what I have read from him), but that is just part of communicating on the Internet.
