It's really hard to say Upstream. It's difficult to get a diagnosis for Aspergers or HFA once you're an adult, because by that time most people have learned compensating behaviours which mask some of the symptoms. I was diagnosed at 4, before my trauma. Did you have delayed speech as a child? That's one of the major indicators of autism vs. aspergers. Kids with aspergers tend to speak at a normal age or even younger, whereas kids with autism usually have severe speech delays and need speech therapy. I wasn't speaking properly until around 6 or 7.

It is really interesting though, I relate to a lot of what you're saying, especially what you said about the Star Trek characters in the other thread. It's actually quite common for us auties and aspies to relate to the non-emotional Star Trek characters. Lots of my autie friends do, though I have never heard many neurotypicals saying they relate to those characters. So who knows, maybe you have some features?
