Social (pragmatic) communication disorder

Social (pragmatic) communication disorder (SPCD), also known as pragmatic language impairment (PLI), is a neurodevelopmental disorder characterized by significant difficulties in the social use of verbal and nonverbal communication. Individuals with SPCD struggle to effectively engage in social interactions, interpret social cues, and use language appropriately in social contexts. This disorder can have a profound impact on an individual's ability to establish and maintain relationships, navigate social situations, and participate in academic and professional settings. Although SPCD shares similarities with other communication disorders, such as autism spectrum disorder (ASD), it is recognized as a distinct diagnostic category with its own set of diagnostic criteria and features.

It has only been since 2013 that SPCD has become its own category in the DSM-5. In creating this new category it allowed individuals to be considered with a form of communication disorder distinct from PLI and Autism Spectrum Disorder (ASD). SPCD lacks behaviors associated with restrictions and repetition which are seen in ASD.
