Asperger's or Autism? What are the different types?
Back to Characteristics
The diagnosis of autism changed with the release of the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSMV) in May 2013. The key change to the new manual for autism is that there is now a single diagnosis of autism, replacing the previous sub-divisions of autistim, Asperger's Syndrome and pervasive developmental disorder - not otherwise specified (PDD-NOS).
Autism is now diagnosed in terms of its severity, with a ranking of 1, 2 or 3, depending on support needs. Diagnosis is now based on difficulties in two areas - deficits in social communication, and fixated interests and repetitive behaviours. See also What is autism?
Asperger’s syndrome is now considered to be part of the autism spectrum, rather than having its own separate diagnosis.
