Autism Spectrum Disorder, Language Disorder, and Social (Pragmatic) Communication Disorder: Overlaps, Distinguishing Features, and Clinical Implications
文摘
The diagnostic boundaries between autism spectrum disorder (ASD) and specific language impairment (SLI) are not clear-cut. Evidence of the lack of distinct boundaries between these disorders comes from research identifying a group of children who have pragmatic language difficulties that can be distinguished from those in children with SLI and those with ASD. These findings have led to the inclusion of a new diagnostic category, social (pragmatic) communication disorder (SPCD), in the Diagnostic and Statistical Manual of Mental Disorders-5th Edition DSM-5. While this new diagnostic category appears to capture a subgroup of children who may not have been recognised in the DSM-IV, SPCD has been criticised due to a lack of empirical evidence, showing that the disorder is distinct from ASD in terms of aetiology, intervention, and prognosis.
