Medical Professionals Who Diagnose Adults

Many people believe that getting an official autism diagnosis will mean they will receive help and services. For adults, there are generally fewer services available than for children. In addition, getting a diagnosis often costs a few thousand dollars out of pocket depending on your insurance. Also, a diagnosis does not mean you will get access to all the services out there. For instance, the Regional Center may still deny services despite having a diagnosis, if for instance, you did not receive any services or therapy as a child while in school.

Luckily, there are various support groups (often free or low cost) that do not require an official diagnosis to attend. You may find answers and reassurances to meet other people on the autism spectrum like yourself. Please check the section on support groups to learn more about these groups.

With that said, you may still want an official autism diagnosis. Most insurance providers will cover some services and therapies if you have an official autism diagnosis. Often a psychologist or primary care provider provides a referral to get an autism diagnosis.
