Social Communication Disorder: Diagnosis

For a child to be diagnosed with social communication disorder, the symptoms of the disorder must be present in early childhood—though they may not fully manifest until speech, language, and communication demands start to exceed her pragmatic skills. Autism spectrum disorder must be ruled out for a SCD diagnosis.

Because the symptoms described in SCD were not defined in previous editions of the DSM, many individu­als with such symptoms may have been included in the not otherwise specified category of perva­sive development disorder.
