I'm not an expert on psychological anything, but

Based on what I've read about personality disorders (not much), they are a diagnosis for when the symptoms develop post adolescence (you were this way before and now you're this way and nobody knows exactly why), whereas for autism and AS the symptoms had to have been present from a very young age even if you or people close to you didn't understand what they were. I think this is why schizotypal has its own diagnosis even though it seems to me (based entirely on jimi's description btw) to be something like a late-onset AS.

Are you prepared to bring in your parents and other people who knew you as a child for these AS tests?
