hi, I think low level asperger's would still be an autism spectrum disorder - dyspraxia is a developmental disorder that manifests itself as a lack of physicqal co-ordination.

Asperger's is more about cognitive and communication issues.

I've got no where searching for "social dyspraxia" - you probably need the psychiatrist to clarify - dyspraxia is a physical disability.

I wonder if they meant "social (pragmatic) communication disorder (SCD)" which is a new diagnostic term in the new edition of the diagnostic manual, the DSM-V:

"Social (Pragmatic) Communication Disorder
The new diagnosis of social (pragmatic) communication disorder (SCD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) will more accurately recognize individuals
who have significant problems using verbal and nonverbal communication for social purposes, leading to impairments in their ability to effectively communicate, participate socially, maintain social relationships, or otherwise perform academically or occupationally. Previous editions of DSM did not provide an
appropriate diagnosis for people with such symptoms, which led to inconsistent treatment across clinics and treatment centers. For these individuals, SCD brings their social and communication deficits out of the shadows of a not otherwise specified label to help them get the services and treatment they need.

Characteristics of the Disorder
SCD is characterized by a persistent difficulty with verbal and nonverbal communication that cannot be explained by low cognitive ability. Symptoms include difficulty in the acquisition and use of spoken and written language as well as problems with inappropriate responses in conversation. The disorder limits effective communication, social relationships, academic achievement, or occupational performance. Symptoms must be present in early childhood even if they are not recognized until later when speech,
language, or communication demands exceed abilities.

Process for a New Diagnosis
New diagnoses were included in DSM-5 only after a comprehensive review of the scientific literature; full discussion by Work Group members; review by the DSM-5 Task Force, Scientific Review Committee, and Clinical and Public Health Committee; and, finally, evaluation by the American Psychiatric Associations Board of Trustees. Trustees approved the final diagnostic criteria for DSM-5 in December 2012.

Improving Diagnosis and Care
While previous editions of DSM included diagnoses with related symptoms, the SCD diagnosis was needed to ensure that the unique needs of affected individuals are met. For example, while autism spectrum disorder (ASD) does encompass communication problems, it also includes restricted, repetitive patterns of behavior, interests or activities and gives equal weight to both communication issues and repetitive behaviors. ASD must be ruled out for SCD to be diagnosed. Because the symptoms described in SCD were not defined in previous editions of DSM, many individuals with such symptoms may have been lumped under the not otherwise specified category of pervasive development disorder. This led to inconsistent treatment and services across different clinics and practices. Research shows that communication disorders are amenable to treatment, so identifying distinct communication problems are an important first step in getting people appropriate care. "
