**2. Adult autism**

All diagnoses of autism have to take a developmental history from childhood, which will include persistent deficits in social communication and social interaction from the early developmental period, as well as restricted, repetitive patterns of behaviour causing clinically significant impairment in functioning (American Psychiatric Association [2]). The problem with adult autism diagnosis will include getting a relatively early history from an informant which may be a parent or other, the problem of camouflaging because of treatment or just life experience which makes it more difficult to diagnose the adult with autism. They may have learned about eye contact, etc. School reports or home videos sometimes help. They will often present with comorbidities, for example, depression, (70%), anxiety (40%), attention deficit disorder or psychosis.
