Aspergers Syndrome

What is Aspergers Syndrome ?

Aspergers Disorder is one of five Pervasive Development Disorders (PDDs), which also includes Autism, Rett's Syndrome, Childhood Disintegrative Disorder, and PDD-Not Otherwise Specified (PDD-NOS). PDDs are a category of neurologically-based disorders that have a range of delays in different developmental stages.

Aspergers Disorder as first described in the 1940s by Viennese pediatrician Hans Asperger who observed autistic-like behaviors and difficulties with social and communication skills in boys who had normal intelligence and language development. Many professionals felt Aspergers Disorder was simply a milder form of autism and used the term "high-functioning autism" to describe these individuals. Professor Uta Frith, with the Institute of Cognitive Neuroscience of University College London and author of Autism and Asperger Syndrome, describes individuals with Aspergers Disorder as "having a dash of Autism." Aspergers Disorder was added to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) in 1994 as a separate disorder from autism. However, there are still many professionals who consider Aspergers Disorder a less severe form of autism.

What distinguishes Aspergers Disorder from autism is the severity of the symptoms and the absence of language delays. Children with Aspergers Disorder may be only mildly affected and frequently have good language and cognitive skills. To the untrained observer, a child with Aspergers Disorder may just seem different.

Children with autism are frequently seen as aloof and uninterested in others. This is not the case with Aspergers Disorder. Individuals with Aspergers Disorder usually want to fit in and have interaction with others; they simply don't know how to do it. They may be socially awkward, not understanding conventional social rules, or may show a lack of empathy. They may have limited eye contact, seem to be unengaged in a conversation, and not understand the use of gestures.

Interests in a particular subject may border on the obsessive. Children with Aspergers Disorder frequently like to collect categories of things, such as rocks or bottle caps. They may be proficient in knowing categories of information, such as baseball statistics or Latin names of flowers. While they may have good rote memory skills, they have difficulty with abstract concepts.

One of the major differences between Aspergers Disorder and autism is that, by definition, there is no speech delay in Aspergers. In fact, children with Aspergers Disorder frequently have good language skills; they simply use language in different ways. Speech patterns may be unusual, lacking inflection or having a rhythmic nature. Speech may be formal and too loud or high pitched. Children with Aspergers Disorder may not understand the subtleties of language, such as irony and humor, or may not understand the give and take nature of a conversation.

Another distinction between Aspergers Disorder and autism concerns cognitive ability. While some individuals with Autism experience mental retardation, by definition a person with Aspergers Disorder cannot possess a "clinically significant" cognitive delay. This does not imply that all individuals with autism have mental retardation. Some do and some do not, but a person with Aspergers Disorder possesses average to above average intelligence.

While motor difficulties are not a specific criteria for Aspergers, children with Aspergers Disorder frequently have motor skill delays and may appear clumsy or awkward.
