Host: What is PDD/NOS? Peggy Halliday: For all intents and purposes PDD/NOS, it means Pervasive Developmental Disorder Not Otherwise Specified, and it should be treated just as you would treat autism, in terms of interventions. It just means that the characteristics are not quite as clear cut, as they are in classic autism. Autism is a spectrum disorder and it really is a continuum of behaviors and so you are going to see children that have any of the behaviors that you are talking about to a lesser or a greater degree. So PDD/NOS is often thought to be a milder form of autism, that may or that may not be true. It just means that they do not have as many of the characteristics that they would have, if they were diagnosing Classic Autism. Now, a lot of times doctors who are diagnosing very young children are reluctant to give a diagnosis of autism, and they will give the diagnosis of Pervasive Developmental Disorder, because that will allow children to receive intervention services, perhaps later they will receive a diagnosis of Classic Autism, perhaps they wont, but at least they are able to receive services with that diagnosis.
