PDD NOS Symptoms

Among five autism disorders, PDD-NOS are most common. It stands for Pervasive Developmental Disorder Not Otherwise Specified. This is a diagnosis which is prescribed in cases of severe social interaction problems, whether these were verbal or nonverbal. This condition is usually mentioned as an atypical kind of autism, as there are some criteria for autism that haven’t been met. Still, it is considered to be a milder condition in comparison with regular autism, but there are some exceptions. Some patients might be less influenced by this while some others might have severe problems. In this article we will take a closer look at some of the most common pdd nos symptoms which will help you distinguish this condition from typical autism.

Common Symptoms

Autism terminology can be quite confusing at times and it’s not really easy to understand all of it. There is a good reason for this as well – autism manifests in a number of different ways, so it’s impossible to simply make a single condition out of it, because symptoms do appear to be different and there are different methods of treatment used for each of these, with some important similarities of course. While some people display more severe damages, like mental retardation, extreme quietness, repeating motoric with hands some other patients tend to show less significant symptoms. These can easily be recognized by the person interacting in a different way, with narrow interests and a wide approach to overall communication.

PDD-NOS make up for a significant percentage of overall autism patients, while Asperger syndrome is much rarer. Atypical forms of PDD can be identified by Mendel’s observation, whether this is done through chromosome abnormality or other genetic syndromes. In case of PDD, most patients show regular intelligence quotient, but shows improved risks of epilepsy.


The point of treatment is to establish control and decrease the effect of symptoms and their function towards the psyche of the patient. It often needs to be adapted to some specific and personalized problems that condition any treatment methods that might happen on the go. If you start early with an intensive programs of education and therapy, there are higher chances for the patient to acquire a new level of undependability and many social and business skills. It has been noted that a proper treatment needs to last up to three years, but there were many cases proving otherwise. As I’ve said before, it really depends on individual issues and the overall condition of the patient, so there are no general conclusions to be made here.

Drugs are often used in order to improve the efficiency of treatment. More than half of children in USA have been prescribed with some psycho-active medicines or something against muscle cramping. There are other types of therapies and interventions, some of which are still pending for scientific research and approval. The only thing missing in these therapies is an empiric support in terms of quality life concepts, as there are always scientific proofs that need to be made and this often jumps ahead of some personal issues.
