Asperger’s Syndrome and PDD NOS

Aspergers Syndrome, a form of high functioning autism spectrum disorder, impacts an individual’s socialization and communication abilities. However, a person with high functioning autism also has average or above-average intelligence.


Most of us take non-verbal cues from people we interact with through body language, expressions or tone of voice. Individuals with Aspergers, however, find this difficult to do. And this can result in anxiety or confusion in their minds.


Aspergers Syndrome (AS) differs from other forms of autism spectrum disorder because there is no delay in language and symptoms are less severe. A child with Aspergers wants to interact with others generally, but finds it hard to do so.


A child with AS or high functioning autism may show symptoms of the condition within the first year itself. A parent or guide may notice something unusual about the infant quite early. Below are some symptoms of the conditions:

  • Fascination with certain interests – The child/adult may be obsessed with a single topic and become an expert in it. This topic can range from airplanes to mathematics or even kitchen appliances. This generally occurs at the expense of all other subjects.
  • Restricted and repetitive patterns of behavior – These include preference for rigid routines and rituals, repetitive hand flapping or body movement, and an emotional attachment to inanimate objects.
  • Restrictive social interactions – The individual finds it difficult to read non-verbal signs and interact with others. As a result, he may prefer being aloof because even normal conversations may pose challenges due to his behavior.
  • Delayed motor skills – The child has a tough time indulging in activities like cycling, catching a ball, running or playing other sports. This results from poor coordination.

Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) is one of the three types of autism spectrum disorder. According to the Diagnostic and Statistical Manual (DSM-IV), PDD-NOS is a diagnosis that is used for “severe and pervasive impairment in the development of reciprocal social interaction or verbal and nonverbal communication skills, or when stereotyped behavior, interests, and activities are present, but the criteria are not met for a specific PDD.”


While PDD-NOS is not included as an option for Autism Spectrum Disorder in DSM-V, it still is often considered as atypical autism i.e. a milder form of the condition, but this is not always true. While some characteristics may be milder, others may be more severe. PDD NOS is different from high functioning autism
