It is known that Asperger's syndrome is one of the forms of Autism Spectrum Disorder.

Asperger's syndrome is a well-defined clinical entity with a rich semiology and relatively characteristic clinical presentation. It is a disorder involving altered neurobiological brain development, characterized by restrained and repetitive behavior patterns and communication issues in several social contexts. This means that people with Asperger's syndrome develop a number of specific features.

The prevalence of Asperger's syndrome is estimated to be 0,06 % in the general population. Even though ASD etiology is complex and still largely unknown, it probably results from the effects of genetic and environmental risk factors.

The classification suggested a differential diagnosis between AS and the type of Autistic disorder associated with normal cognitive functioning, also known as high functioning autism (HFA) where IQ > 70.

The diagnosis of AS required:

  • at least two symptoms of social interaction impairment and at least one each from symptoms of communication and restricted, repetitive behavior
  • delays or abnormal functioning in at least one of the areas of social interaction, language as used in social communication, or symbolic or imaginative play with onset prior to age 3 years.

Diagnostic criteria for autistic disorder (or another specific PDD) should not be met (otherwise, the AS diagnosis is excluded, and the autistic disorder diagnosis should have precedence).

Asperger syndrome contrasted from autistic disorder in:

  • Absence of diagnostic criteria in the communication domain
  • Absence of a requirement for onset before age 3
  • Addition of criteria specifying the absence of a language delay
  • Addition of criteria specifying the absence of a deficit in cognitive development
