There are currently no standard diagnostic criteria for adults with suspected ASD, but they are in development.
In the meantime, clinicians primarily diagnose adults with ASD through a series of in-person observations and interactions. They also take into consideration any symptoms the person reports experiencing.
If you’re interested in being evaluated for ASD, begin with your family doctor, who will evaluate you to be certain that there isn’t an underlying physical illness accounting for your behaviors. Your doctor may then refer you to a psychiatrist or psychologist for in-depth assessment.
The clinician will want to talk with you about any issues you have regarding communication, emotions, behavioral patterns, range of interests, and more. You’ll answer questions about your childhood, and your clinician might request to speak with your parents or other older family members to gain their perspectives about your lifelong behavior patterns.
