How are ASDs diagnosed?
There is no medical test for ASDs. Doctors look at behavioral symptoms to make a diagnosis. Typically, a diagnosis is made after a thorough evaluation. Such an evaluation may include clinical observations, parent interviews, developmental histories, psychological testing, speech and language assessments, and possibly the use of one or more of a variety of autism diagnostic scales. Because ASDs are complex disorders, a comprehensive evaluation may also include physical, neurological, and genetic testing.
