I have had some experience of working with young adults [14-20]. This is unique work and it does take some time because, as you know, if you have a child with this diagnosis each child is different in how the syndrome presents in them. The nature of Aspergers often means that establishing a relationship can be slow. However I have found that once this happens the work of helping that young person with obsessive behaviour, anxiety, and other issues is completely possible.
