I'm suggesting that the isolation might be causing it. I know that, for my era, I had a very isolated
life - no other children around until school. Now, some of that might have been an effect of what
I was - I don't know for sure - but it strikes me that the anti-social upbringing made patterns. This
is really what I always assumed, until I started seeing some newspaper articles on Asperger's. Along
with some thoughts that I had autistic tendencies, but clearly didn't fit into that model.
As theories go, your's no worse than the others, like thimerol. Except for being wrong, of course, as research will show you if you care to look.
My understanding is that they don't know precisely how much of Autism is
purely genetic, much less Asperger's.
But the research pretty clearly indicates that social factors, such as isolation, do no play a part. Autism and AS are both acquired prenatally or early in life, before social factors such as isolation can do anything. Modern research suggests that AS is part of the autism spectrum, but also that it may not be meaningful to keep AS and HFA as separate dx's.
Remember, while not so long ago, autism was blamed on refrigerator mums, that theory was finally rejected. Today, no serious researcher would even mention it.
