My father is a registered mental nurse and (claims he) has in depth knowledge of psychology and psychiatry of adults, although he is somewhat weaker when it comes to child psychology. Apparently he knew nothing about AS until I told him about it last year.
I am 99.999% sure that I suffer from AS, and barely a term went by at school during the second half of the 1980s before seeing a doctor or a psychologist and none of them had a clue what was wrong with me. My father has contacts in the psychiatric profession and nobody there had any explanation either.
I find it quite surprising that virtually no research into AS ever took place in Britain before the paper by Hans Asperger was translated into English.
