Many parents wonder, "how do I know if my child has PDD-NOS?" This checklist will help you answer this question by focusing on the signs and symptoms of PDD-NOS that you might notice in your child.
What is PDD NOS?
If you are asking "how do I know if my child has PDD-NOS?" you probably have some idea of what the diagnosis means. The acronym PDD stands for Pervasive Developmental Disorder, and all disorders on the autistic spectrum (PPD-NOS, autism, Asperger's syndrome) are considered PDDs.
The acronym NOS stands for "Not Otherwise Specified" - which means that children with PDD-NOS share some of the same symptoms as others on the autistic spectrum, but do not meet the criteria for true autism or Asperger's syndrome. For example, a child with PDD-NOS may meet all of the other criteria for Asperger's syndrome except for the fact that children with Asperger's syndrome only lack language skills in social areas, whereas PDD-NOS child may lack language skills in all areas.
The following three sections list questions that you can use as a checklist to see if your child may have PDD-NOS.
