This thread is fascinating. I especially respect those who are sharing their experiences and their thoughts about those experiences. In contrast to what Greg F said about anecdotal versus scientific evidence I would imagine that everyone would agree that a person who lives with a particular condition has the ultimate anecdotal evidence, and absolutely no one could say it was not of the greater value.

That is as true of Asperger's and autism as it is of psoriasis or brown hair or musical talent We live anecdotally - if there is such a word- and sharing anecdotes is basic.

Maple Leaf Boy, not that it has anything to do with Asperger's, your story reminds me of a friend of mine. He told me that when he was a little boy and got upset his mother would stroke his head, and that later in his life when he became upset he would stroke his own head, and that it helped. :)
