Asperger Syndrome/Asperger’s Disorder


Asperger’s Disorder is one of the newest members of a family called Autism Spectrum Disorders, also known as Pervasive Developmental Disorders (PDDs). Therefore, Asperger’s is considered a Pervasive Developmental Disorder as found in the DSM-IV. Asperger’s Disorder was added as a diagnosis to the DSM-IV in 1994.

Hans Asperger was an Austrian pediatrician and the Director of the University Children’s Clinic in Vienna. He spent most of his professional life in Vienna and published his studies predominantly in German. In 1944, Asperger described a condition he termed ‘autistic psychopathy’ after observing four children in his practice who had difficulty integrating socially. Although their intelligence appeared normal, the children lacked nonverbal communication skills, failed to demonstrate empathy with their peers and were physically clumsy.

Hans Asperger’s observations were published in German and were not widely known until 1981, when an English doctor named Lorna Wing published a series of case studies of children showing similar symptoms, which she called “Asperger’s” syndrome. Wing’s writings were widely published and popularized. Asperger’s became a distinct disease and diagnosis in 1992, when it was included in the tenth published edition of the World Health Organization’s diagnostic manual, International Classification of Diseases (ICD-10), and in 1994 it was added to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), the American Psychiatric Association’s diagnostic reference book.
