For example, the DSM-IV was published in 1984 and revised in 2000. However, it can take a significant amount of time for each revision to be completed. It is revised periodically to incorporate the newest research findings and evolving notions of the human brain. The DSM is published by the APA and serves as the “rulebook” for diagnosing mental conditions, including autism. How has the understanding of autism evolved from the DSM-IV to the DSM-5? Chung is the associate clinical professor of pediatrics and the medical director of the Center for Autism and Neurodevelopmental Disorders at University of California, Irvine, an Autism-Speaks supported Autism Care Network site. Chung discusses the diagnostic criteria for autism in the DSM-5, ways the understanding of autism has evolved and the benefits of a formal diagnosis.ĭr. Thanks to years of research, our understanding of ASD has grown dramatically, leading to significant changes in the Diagnostic and Statistical Manual of Mental Disorders (DSM), the manual published by the American Psychiatric Association (APA) and used by clinicians to diagnose autism and other disorders.
