How can i you determine autism in an adult?

Autism : Autism or autism spectrum asbergers syndrome can be determined with the help of a psychiatrist or neurologist.

Adult diagnosis: It can be difficult to find a provider. I suggest a psychiatrist or psychologist evaluation. Contact your local autism support group for suggestions.

The same DSM-V : criteria of qualitative impairments in social reciprocity & social communication plus narrow, restricted areas of interest or stereotypical motor movements with onset before age 3 are used by adult psychiatrists, neuropsychologists & psychologists to diagnose Autistic Spectrum Disorder in adults as for diagnoses in children.
