PDD-NOS Symptoms and Treatment

A person is diagnosed with PDD-NOS if they have some behaviors seen in autism but don’t meet the full criteria for having Autistic Disorder.

All children with PDD-NOS do not have the same degree or intensity of the disorder. PDD-NOS can be mild, with the child exhibiting only a few symptoms while in the school or neighborhood environment. Other children may have a more severe form of PDD-NOS and have difficulties in all areas of their lives.

There is no set pattern of symptoms and signs in children with PDD-NOS. Symptoms vary in severity and age of onset. A single child seldom shows all the features seen in PDD-NOS at one time.
