The greatest decreases in diagnosis were among individuals with intelligence quotients (IQs) over 70 and those with a previous diagnosis of PDD-NOS or Asperger's Disorder (Maenner et al., 2014 Smith et al., 2015). Impact of DSM-5 on Practiceīetween 50% and 75% of individuals diagnosed with PDD under the DSM-IV-TR will maintain a diagnosis of ASD using DSM-5 criteria (see Smith et al. See Paul (2013) for a more detailed discussion of DSM-5 changes and potential practice implications.Īlthough subtypes are no longer specified, the DSM-5 notes, "Individuals with a well-established DSM-IV TR diagnosis of autistic disorder, Asperger's disorder, or pervasive developmental disorder not otherwise specified should be given the diagnosis of autism spectrum disorder" (APA, 2013, p. Severity ratings are used for descriptive purposes only and not to diagnose or determine eligibility for services (APA, 2013).
Severity may vary by context and may fluctuate over time. Each severity level specifies the amount of support needed to function in the general community, given the individual's social communication skills and degree of restricted, repetitive behaviors. Recognition of unusual reactions to sensory input (e.g., hyper- or hypo-reactivity to sensory input unusual interest in sensory aspects of environment).Īccording to the DSM-5, individuals who meet the specified criteria are given the diagnosis of "autism spectrum disorder (ASD)" with one of three severity levels. Omission of criteria related to delay in or lack of development of spoken language and, instead, allowance for the clinician to specify whether ASD occurs "with or without accompanying language impairment."Ĭhange in age of onset from "prior to 3 years" to the presence of symptoms "in the early developmental period." ( Note: The DSM-5 lists Rett syndrome, a genetic disorder, as a separate diagnosis in which disruptions of social interaction may be observed during the regressive phase). The DSM-5 criteria for ASD (the term used in place of PDD) encompass the social and behavioral deficits typically associated with these populations but no longer specify subtypes.

The criteria specified in the DSM-5 reflect a number of changes from those in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (Text Revision DSM-IV-TR ), the most notable of which are the following:Įlimination of the Pervasive Developmental Disorder (PDD) category that included diagnoses of Autistic Disorder, Asperger's Disorder, Childhood Disintegrative Disorder, Rett's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). This definition is consistent with the diagnostic criteria for ASD described in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5 American Psychiatric Association, 2013). Restricted, repetitive behaviors, interests, or activities are manifested by stereotyped, repetitive speech, motor movement, or use of objects inflexible adherence to routines restricted interests and hyper- and/or hypo-sensitivity to sensory input. Social communication deficits present in various ways and can include impairments in joint attention and social reciprocity as well as challenges using verbal and nonverbal communication behaviors for social interaction. See the Autism Spectrum Disorder Evidence Map for summaries of the available research on this topic.Īutism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and social interaction and the presence of restricted, repetitive behaviors. For more detailed information and resources about social communication disorders across the lifespan, including information about social communication deficits without repetitive behaviors, see the Social Communication Disorder Practice Portal page. The scope of this page is autism spectrum disorder (ASD) across the lifespan.
