One issue with autistic spectrum disorders is that many people go undiagnosed. There is a belief of a \u201clost generation\u201d of people who are unaware they have the disability. In this programme campaigners Georgia Harper and Sam Ahern, both of whom have autism, attempt to get rid of some of the myths concerning the condition, and show others what it is really like to have it. Are You Autistic? is on Channel 4 at 20.00.
