The presentation will extensively review literature on the evolution of American Psychiatric Association's diagnostic system (DSM) for Autism. It will discuss the concerns by many professionals in the field of autism regarding the potential impact of DSM-5 ASD on many aspects of ASD including epidemiology, educational interventions, medication treatment, and forensic issues. The definitions and the diagnostic criteria of Autism have changed over the past years. The changes will have a substantial impact in several fields: epidemiology, diagnosis, treatment, research, education, and regulations. This presentation will show the evolution of the American Psychiatric Association's diagnostic system (DSM) regarding Autism.

The presentation will describe the recently published DSM-5 ASD which has a very different definition of Autism as comparing to the definition and diagnostic criteria used by the field of Autim from 1980 to 2013. The new DSM-5 ASD, a single category disorder, has shown that the prevalence of ASD is reduced about 30%. Many individuals diagnosed as having ASD based on DSM-IV and DSM-III will no longer be considered as having ASD and may lose their treatment benefits. In the future, many individuals with significant ASD features will not be diagnosed as having ASD and will not be able to obtain needed treatments. This presentation will provide information and guidelines to assist individuals with ASD and their careproviders to obtain the needed helps/interventions.

On the other hand, more than 30 years of research results and learned knowledge of Autistic disorder, Asperger disorder, and PDDNOS, will be lost or wasted due to the changed concept of Autism by the new DSM-5 ASD. This presentation will show the validity of the previous research results to argue for the continuous study of the "subtypes of ASD" and to provide suggestions for additional research approach in the future so that ten or twenty years later the field will again consider "ASD subtypes" concept with all the new and additional research data to support such a concept.

Learning Objectives:

Explore the impacts of the new DSM-5 ASD on the diagnosis and prevalence of ASD, the implication of treatment of ASD and the outcome of ASD
Examine the changes of diagnostic systems (DSM)from DSM-III to recently published DSM-5 regarding Autism and the attendees will learn what problems have been considered in the new DSM-5 ASD
Discuss what would be a more appropriate and productive way of applying the new DSM-5 ASD diagnostic criteria to daily practice and research endeavors
