How is Autism Diagnosed?

There is no one test for autism. Autism is diagnosed based on clinical observation, and testing professionals using one or more standardized tests. Professionals most likely to diagnose autism are psychologists, psychiatrists, developmental pediatricians, and speech-language pathologists. Some of the screenings and tests which may be used in the diagnostic process are: CARS (Childhood Autism Rating Scale), Autism Diagnostic Checklist Form E-2, CHAT (Checklist for Autism in Toddlers), M-CHAT (Modified Checklist for Autism in Toddlers), Pervasive Developmental Disorders Screening Test -2, ADOS (Autism Diagnostic Observation Scale), and ADI-R (Autism Diagnostic Interview-Revised). In addition, parental interview and medical history are taken into consideration.

The current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) has specific criterion required to make a diagnosis of autism, or a Pervasive Development Disorder. There are five disorders under the PDD umbrella which include Autism, Aspergers, Rhett's Syndrome, Childhood Disintegrative Disorder, and PDD-NOS (not otherwise specified). 

Three Things Parents Can Look For at Home:

1. Does the child look at you and point when he/she wants to show you something?
2. Does the child look at you when they point to something?
3. Does the child use imagination to pretend play?

If the answer to these questions is no, your child may be at risk for autism. Consultation with a qualified provider such as Autism Community Network is recommended. Call (210) 435-1000 for assistance.
