If you're seriously looking for advice this has to be a question for medical professionals who have been able to study your brother properly. How ever much additional information you might offer in a forum such as this, we'd still be guessing. The list of characteristic behavior usually associated with autism, or Asperger's Syndrome, as well as an introduction to the kind of treatment and support available, is all listed at sites like
http://www.autism-resources.com/autism.faq.html
but don't let a website answer your questions about this condition!
I really hope this wasn't a joke question. This is not the place to attempt 'humour' about a medical condition!
