My son was diagnosed at a very late age and is now comfortable about his autism. I would be reluctant to confront him with anything that would seem like a cure. In his mind he tends to think that it is all his fault and needs constant reasurrance. He is in the position at last to meet with people who understand. However, not all care workers themselves know all about the different aspects of autism unless it is their particular field we had to track down a particular person who specialised in it. He also has an occupational therapist (not specialised in autism) who occasionally has to be re-reminded about some of the issues regarding autism and so as soon as there is another hiccup (putting it politely) we have to sort it all out again. The worst thing is when he is promised that something is going to happen and it falls through. With my son he has to have structure something concrete to focus on rather than cures or wishy washy promises.
