Yes, these criteria have been developed for children, however, adults undergoing evaluation are usually asked about their childhood development. The clinician must rely upon the individuals memories, eye witness accounts (such as a parent or sibling or school reports). This information about one's childhood is one of the things that helps the clinician to make their decision on a diagnosis. Many people withe Asperger's have learned adaptive behaviors through the years (didn't you do a post on this The_little_didgee?), while others have never experienced some of what is considered symptomatic of Asperger's. Again, each person is a unique individual and the original post should not be taken as anything more than a thought provoking question based upon material found on the two disorders from authoritative websites.
