Autism didn’t make its debut in the DSM until 1980. In 1987, a new edition expanded the criteria by allowing a diagnosis even if symptoms became apparent after 30 months of age. Autism’s reported prevalence in the U.S. has climbed steadily in the past few decades. Researchers attribute most of this increase to changes in how the prevalence is measured, increased awareness of the condition and shifts in the criteria for diagnosing autism.

There is no blood test, brain scan or any other objective test that can diagnose autism — although researchers are actively trying to develop such tests. Clinicians rely on observations of a person’s behavior to diagnose the condition.


In the U.S., the criteria for diagnosing autism are laid out in the “Diagnostic and Statistical Manual of Mental Disorders” (DSM). #DSM The criteria are problems with social communication and interactions, and restricted interests or repetitive behaviors. Both of these ‘core’ features must be present in early development.
