Asperger's syndrome is no longer given as a category in the DSM-5 because it is assimilated into the ASD rating scale. Asperger's syndrome would fall into the "Autism Spectrum Disorder - Level 1" category. You can see why most people continue to use the term Asperger's :-) The DMS-5 states:

"Individuals with a well-established DSM-IV diagnoses of autistic disorder, Asperger’s disorder, or pervasive developmental disorder not otherwise specified should be given the diagnosis of autism spectrum disorder”. (Not Social Communication Disorder).
