The term pervasive developmental disorders (PDDs) refers to a group of developmental conditions that involve delayed or impaired communication and social skills, behaviors, and cognitive skills (learning)
 
The features of PDD-NOS are severe and pervasive impairment in the development of reciprocal social interaction or verbal and non-verbal communication skills. The behavior a child displays might include stereotyped behaviors, interests, and activities.

A child with PDD-NOS has symptoms similar to autism disorder, they are not diagnosed with autism because the symptoms started at a late age, may have behaviors that are different than a child with typical autism or do not have all the symptoms of autism.
 
Children with PDD-NOS have severe impairment with social skills, verbal and nonverbal communication skills, and may have stereotyped behavior, interests, and activities.
 

Evaluation

Your child may have an evaluation with a speech language pathologist or occupational therapist depending on the reason you are coming to therapy. The therapist will talk with you about your child’s medical history and what difficulties they are having in a typical say. The therapist may use formal tests as well as caregiver questionnaires. They will observe and interact with your child to complete a  social skills assessment.

Treatment

Use of language treatment strategies to help with processing of information as well as specific training in social skills including individual speech therapy and/or social skills group participation.

Occupational therapy can help with sensory integration issues, possible feeding issues (speech or OT) and self-help /care and fine motor skills.
