The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) which was published in May 2013 canceled Asperger's disorder as a separate diagnosis and homogenized it under autism spectrum disorder, with severity measures within the broader diagnosis.[33][34] The DSM 5 noted that "Individuals with a well-established DSM-IV diagnosis of" "Asperger’s disorder" "should be given the diagnosis of autism spectrum disorder."[35]
