title: Autism, Language Disorder, and Social (Pragmatic) Communication Disorder: DSM-V and Differential Diagnoses.
abstract: • Based on strong research evidence (1), the prevalence of autism spectrum disorders (ASDs) has increased over the past decade, with a 2010 prevalence of 1:68 (1.5%) in children age 8 years. • Based on some research evidence as well as consensus (3), the most recent revision of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM-V) identifies two core dimensions for the diagnosis of ASD: social (social communication and social interaction) and nonsocial (restricted, repetitive patterns of behaviors, interests, or activities). • Based on some research evidence as well as consensus (3) (31) (32) (33) (34), DSM-V identifies social pragmatic communication disorder (SPCD) as a dissociable dimension of language and communication ability that affects how individuals use language for social exchanges. SPCD is often found in children with language impairments and children with attention-deficit/hyperactivity disorder and other genetic/neurologic conditions. • Based on strong research evidence (2) (26) (27) (28), childhood language disorders affect 7.4% of kindergarteners, and 50% to 80% of these children experience persistent language, academic, and social-emotional difficulties into their adult years, despite having normal nonverbal cognitive abilities. • Based primarily on consensus due to lack of relevant clinical studies, differential diagnosis of autism and language disorders may require a multidisciplinary evaluation that takes into account a child’s overall development, including cognitive, communication, and social abilities. Monitoring the response to appropriate interventions and trajectory of development over time may improve the accuracy of diagnosis, especially in very young children.
