What is Pervasive Developmental Disorder Not Otherwise Specified?

Sometimes a child will show some, but not all, of the signs of Autism.  Or they may show signs of Autism some of the time, but not all of the time.  Or, again, they may show the signs in some, but not all, places.  This condition may be classified as Persuasive Developmental Disorder Not Otherwise Specified.  This long name is often shortened to PDD-NOS. Some childeren may show these signs while still a baby, but PDD-NOS is Usually seen first in children who are three or four years old.  Several different types of signs may be seen. We will explore two of the main types here.

Social Interaction

Even when a child is still an infant, delays in development of social interaction can often be noticed. The child often will not look people in the eyes.  They may not smile when you are playing with them.  They usually will not extend their arms to be picked up. They sometimes prefer to play by themselves, away from other people.  Children with PDD-NOS may sometimes enjoy being cuddled, however. They also may enjoy wrestling or rough housing with their parents or older brothers or sisters.

Children with PDD-NOS usually do not display problems with being separated from their parents.  Strangers may also not be a problem. In fact, they often will run right up to strangers just as they would to their parents. Older children with PDD-NOS will usually have close relationships with their parents and other adults. They usually find it difficult to make friends. They do not want to participate in games with other children. Many children with mild PDD-NOS do want to have friends, but because it is hard for them to interact socially, making friends will be hard for them.

Communication Impairments

Communication impairment can start very early in children with Persuasive Developmental Disorder Not Other Specified (PDD-NOS). Frequently the babbling and attempts to talk common to other children will not be present in the PDD-NOS child.  They may, however, learn a single word and repeat it over and over again.

In some cases, PDD-NOS children learn to speak fairly easily, but they often will not use the right words for the situation. They will often not understand the tone of voice people use when when they are joking or being sarcastic. They take what people say literally.  If someone tells the child that it is raining cats and dogs, for example, they might go to a window and look out to see the cats and dogs falling from the sky. Children with Persuasive Developmental Disorder Not Otherwise Specified will frequently talk only about topics that interest them. They may seem to be talking at you, not talking with you.

Children with Persuasive Developmental Disorder Not Otherwise Specified usually experience emotions in the extreme. When they are angry they may throw temper tantrums that will be more severe and last much longer than would be expected in normal children. Fears, sadness, and other emotions may also cause problems. At times they may be extremely happy. At other times they may be extremely sad.  Their facial expressions usually will not go along with the emotion.

There are many signs of a child with Persuasive Developmental Disorder Not Otherwise Specified. These are just two of them.  If you notice signs such as these in your child, tell their doctor of your concerns. The doctor can help by examining the child and suggesting further if he/she feels it is advisable.
