My 33-year-old son had ADHD as a child and was treated by a pediatric psychologist for several years. Because he was considered different by his peers, he was often teased and not liked. Now, as an adult, remembering that experience makes him angry. Recently, I am noticing what I believe to be Asperger's disorder symptoms in him. He has outstanding retention of information, and his focus on computers is intense. His conversation moves from subject to subject, but he seems to have problems listening to others and often misunderstands content or their intentions. However, he does not recognize symptoms of Asperger's in himself. Are there support groups he can attend for adults so that he can see he is not alone – and maybe learn better interpersonal skills – so he can eventually have a mate and do better at work?

A significant percentage of children with ADHD continue to manifest the condition as adults. Your son’s problems with socialization may be characteristic of one of the autism spectrum conditions, which include Asperger's syndrome. However, without a more thorough evaluation, it is impossible to make this determination.

Support groups are usually designated for individuals with specific diagnoses. Therefore, I suggest if your son is sufficiently motivated, he should contact a psychiatrist or psychologist well-versed in autism for a thorough assessment.
