Psychiatrists (M.D.) can diagnose autism and prescribe medication. However, psychiatrists do not conduct formal testing, and typically provide very short appointments. For an adult who has passed through life under the radar, a more comprehensive diagnostic evaluation is strongly advised.

The mental health professionals listed at right have a degree and licensure that grants them diagnostic privileges.

Not all mental health professionals conduct evaluations, however. Some solely provide therapeutic services. In order to save yourself both time and money and to ensure that you are going to be able to receive the services you are seeking, it is best to ensure that your provider conducts diagnostic work prior to making an appointment.
