Social Communication Disorder is a neurodevelopmental disorder. Patients with social communication disorder have difficulties understanding and using appropriate verbal and nonverbal language for social purposes such as regulating and interacting with others, following rules for storytelling and conversation (initiating or entering a conversation, maintaining the topic, taking turns), making and keeping appropriate peer relationships and understanding nonliterate or ambiguous information (ex. jokes, idioms, riddles, etc.).
Social communication disorder is not linked to low cognitive abilities, Autism Spectrum Disorder, medical or neurological conditions, weak vocabulary or grammatical skills. It can coexist with other developmental disorders such as language impairment, learning disabilities, speech sound disorder, attention-deficit/hyperactivity disorder and traumatic brain injury.
