Diagnosis of Asperger syndrome can be tricky as there is a lack of a standardized diagnostic screening for the disorder. Developmental screening during a routine check-up by a general practitioner or pediatrician may identify signs that warrant further investigation. This will require a comprehensive diagnosis of development disorders of preschool age evaluation to either confirm or exclude a diagnosis of AS.
This team usually includes a psychologist, neurologist, psychiatrist, speech and language pathologist, occupational therapist and other professionals with expertise in diagnosing children with AS. AS, PDD-NOS and atypical autism was similar to that for classic autism. Parents of children with AS can typically trace differences in their children’s development to as early as 30 months of age, although diagnosis is not made on average until the age of 11. By definition, children with AS develop language and self-help skills on schedule, so early signs may not be apparent and the condition may not be diagnosed until later childhood or even old age. Diagnostic confusion burdens individuals and families and may cause them to seek unhelpful therapies. Differentiating between AS and other ASDs relies on the judgment of experienced clinicians. There is much overlap between AS and NLD: both have symptoms of precocious reading, verbosity, and clumsiness, but they differ in that children with AS have restricted interests, repetitive behaviors, and less-typical social interactions.
The diagnosis of AS is complicated by the use of several different screening instruments. In addition to the DSM-IV and the ICD-10 criteria, other sets of diagnostic criteria for AS are the Szatmari et al. Compared with the DSM-IV and ICD-10 criteria, the requirements of normal early language and cognitive development are not mentioned by Szatmari et al. Gillberg and Szatmari include “odd speech” and “language” in their criteria.
The distinction between Asperger’s and other ASD forms is to some extent an artifact of how autism was discovered. Although individuals with Asperger’s tend to perform better cognitively than those with autism, the extent of the overlap between Asperger’s and high-functioning autism is unclear. AS and HFA and aid in differential diagnosis. May 2013 canceled Asperger’s disorder as a separate diagnosis and homogenized it under autism spectrum disorder, with severity measures within the broader diagnosis. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
The diagnosis is broken down into 3 levels of severity. The removal of Asperger’s Disorder from the DSM has been controversial as it is commonly used by health insurers, researchers, state agencies, schools, and individuals with the disorder. Experts are concerned that eliminating the Asperger’s label will prevent mildly affected people from being evaluated for Autism. Autism and Asperger syndrome: an overview”.
