Wednesday Definition: Asperger Syndrome

Because Asperger’s is on the Autism spectrum – actually considered a form of high functioning autism – here are the essential features of Asperger’s Disorder and how it differs from Autism:
Criterion A. Severe and sustained impairment in social interaction
Criterion B. The development of restricted, repetitive patterns of
behaviour, interests, and activities
Criterion C. The disturbance must cause clinically significant impairment
in social, occupational, or other important areas of
functioning.

Criterion D. In contrast to Autistic Disorder, there are no clinically
significant delays in language (eg: single words are used
by age 2 years, communicative phrases are used by age 3
years).
Criterion E. There are no clinically significant delays in cognitive
development or in the development of age-appropriate
self-help skills, adaptive behaviour (other than in social
interaction), and curiosity about the environment in
childhood.
Criterion F. The diagnosis is not given if the criteria are met
for any other specific Pervasive Developmental Disorder or
for Schizophrenia.
