![]() ![]() While this change has gotten a lot of media attention, the end result is likely not to be significant to people who are diagnosed with an autism spectrum disorder. The symptoms of some patients diagnosed with DSM-IV pervasive developmental disorder not otherwise specified may meet the DSM-5 criteria for social communication disorder. Because social communication deficits are one component of autism spectrum disorder (ASD), it is important to note that social (pragmatic) communication disorder cannot be diagnosed in the presence of restricted repetitive behaviors, interests, and activities (the other component of ASD). The DSM-5 communication disorders include language disorder (which combines DSM-IV expressive and mixed receptive-expressive language disorders), speech sound disorder (a new name for phonological disorder), and childhood-onset fluency disorder (a new name for stuttering).Īlso included is social (pragmatic) communication disorder, a new condition for persistent difficulties in the social uses of verbal and nonverbal communication. ![]() Despite the name change, the deficits in cognitive capacity beginning in the developmental period, with the accompanying diagnostic criteria, are considered to constitute a mental disorder. ![]() Moreover, a federal statue in the United States (Public Law 111-256, Rosas Law) replaces the term mental retardation with intellectual disability. Why was the terminology of mental retardation changed? “Intellectual disability is the term that has come into common use over the past two decades among medical, educational, and other professionals, and by the lay public and advocacy groups. ![]() Severity is determined by adaptive functioning rather than IQ score.” Hello “intellectual disability.”Īccording to the APA, “diagnostic criteria for intellectual disability (intellectual developmental disorder) emphasize the need for an assessment of both cognitive capacity (IQ) and adaptive functioning. As our mechanistic understanding of autism improves, diagnoses based on behavioral parameters will continue to provide opportunities for interventions targeting the behaviors, while etiological diagnoses will provide opportunities for interventions tailored to etiology.Intellectual Disability (Intellectual Developmental Disorder)īye bye “mental retardation,” a now politically-incorrect term out of vogue for over a decade. We support the evidence-based changes to autism diagnosis found in DSM-5, and look forward to further studies on the autism phenotype as this has implications for diagnosis and treatment. The commentaries go on to discuss the positive aspects of these changes and raise some areas of potential concern. In addition, DSM-5 collapses social and communication domains into a single combined domain. Both commentaries note how DSM-5 collapses the earlier diagnostic categories of the pervasive developmental disorders into a single category of autism spectrum disorder. We are fortunate to have invited commentaries from the laboratories of Dr Cathy Lord and Dr Fred Volkmar offering their perspectives on the new Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria for the autism spectrum. ![]()
