I agree with you Planet Autism–that Asperger’s and autism are related. I meant that they’re substantially different, but I think they are still related. I’m sorry if I wasn’t more clear in my blog. I don’t think I would have regressed if I hadn’t already had Asperger’s, which as you know is generally considered to be part of the so-called spectrum. Since I’ve written this I’ve been in contact with two other people who have regressed as adults. I definitely think there’s a sort of association that makes this possible. I’ve also observed the same thing you have–Asperger’s parents with children who are more severely autistic. Though there are neurotypical parents with severely autistic kids too.
