What is Pervasive Developmental Disorders PDD-NOS

PDD-NOS is a term used to describe Pervasive Developmental Disorder-Not Specificated. PDD-NOS was among the subtypes of autism previously distinct that were combined into the one diagnostic of autism spectrum disorders (ASD) following the publication of the DSM-5 diagnostic manual in 2013.

The past was when psychiatrists and psychologists frequently used the terms “pervasive developmental disorders” and “autism spectrum disorders” (ASD) in conjunction. Thus, PDD-NOS came to be the name used for individuals who fall autistic but aren’t able to meet the requirements for another ASD like autistic disorder (sometimes also referred to as “classic” autism) or Asperger syndrome..

As with all kinds of autism, PDDNOS can be associated with a broad spectrum of intellectual abilities. The most distinctive features of PDD-NOS are problems with language and social development.

Subthreshold autism

Certain developmental health professionals call PDD-NOS “subthreshold autism.” In this sense, it’s the term they use to describe those who have certain, but not all, traits of autism or exhibits moderate symptoms.

  • A high-functioning population (around 25%) who’s symptoms are mostly in sync with the symptoms in Asperger syndrome, yet who differ in the sense that they have an insufficient development of language as well as mild cognitive impairment. (Asperger syndrome doesn’t typically have a speech delay or cognitive impairment).
  • Another category (around 25%) who’s symptoms closely resemble the symptoms of autism however, they do not satisfy all the diagnostic symptoms and signs.
  • A third category (around 50%) that meet the requirements for diagnosing autistic disorders however, their typical and repetitive behaviors are noticeablely moderate.

These findings suggest that people suffering from PDD-NOS can differ significantly in their strengths and weaknesses..
