What is Asperger syndrome?

Asperger syndrome, also known as Asperger’s syndrome or simply Asperger’s, is the old name for a condition that is now recognized as part of autism spectrum disorder (ASD). Since 2013, Asperger’s has no longer been used as a separate medical diagnosis in large parts of the world including the U.S., though many people continue to use the term in their personal lives or colloquially. 1

People who previously might have been diagnosed with Asperger’s would generally be considered to be on the higher functioning end of the autism spectrum and may have less severe symptoms than others affected by autism. Their IQ is usually in what is considered to be the normal or above-normal range, and their language skills may be very good. However, they still experience challenges with communication. 2

Autism spectrum disorder is a lifelong developmental disorder that significantly affects the ways in which people communicate and interact. 2 For some people, a diagnosis of Asperger’s may not have been made until fairly late in childhood or adulthood, as signs of the condition may not have been immediately recognized.

Symptoms of Asperger syndrome

While they tend to vary from person to person, signs of autism spectrum disorder that may have previously led to a diagnosis of Asperger syndrome include: 3 4 5

  • A narrow range of interests or obsession with certain topics
  • Difficulties with social situations and communication with others
  • Speech and hearing abnormalities
  • Heightened sensory sensitivity
  • Placing high value on rules and routines

Symptoms such as these may sometimes be referred to as Asperger’s traits or characteristics. 6

In addition, typical physical signs that may have previously led to a diagnosis of Asperger syndrome include: 5

  • Clumsiness
  • Hypermobile (loose) joints
  • Difficulties with walking, balance, handwriting, rhythm and other coordinated movements
  • Difficulties with ball play

Good to know: People who might have previously been diagnosed with Asperger syndrome tend to have normal or above-average intelligence, but may behave insensitively in social situations. They may also appear indifferent toward their loved ones. 5

Asperger’s in women

Autism spectrum disorder is diagnosed more often in men, and symptoms may not be recognized as quickly, if at all, in girls and women. This may lead to possible underdiagnosis of the condition, particularly in those who could be considered to be higher-functioning.

  • Not expressing emotion or expressing only a limited range of emotions
  • Difficulty understanding emotions in others
  • Lack of interest in playing with other children
  • Interest in one particular toy or object

Diagnosis of Asperger syndrome

Asperger’s was previously a separate medical diagnosis. However, in 2013, Asperger syndrome was classified under the umbrella of autism spectrum disorder with the introduction of the widely-used Diagnostic and Statistical Manual of Mental Disorders 5, or DSM-5. 1 8

In the International Classification of Diseases, tenth edition, or ICD-10, another major diagnostic manual, which is used in the U.K. among other parts of the world, Asperger syndrome still appears as a diagnosis under pervasive developmental disorders. However, with the adoption and implementation of the new edition, ICD-11, this is due to change, classifying Asperger’s as part of autism spectrum disorder in line with the DSM-5. 9 10 11

Autism spectrum disorder, whether in a child or adult, can only be diagnosed by a licensed healthcare professional. They will typically use a number of different assessments and tests to confirm the diagnosis.
