Pervasive Developmental Disorder
Pervasive Developmental Disorder
Pervasive Developmental Disorder (PDD) is a term that was formerly used to refer to a group of five different disorders characterized by delays in the development of multiple basic functions including socialization and communication. The five disorders under PDD were autism, Asperger syndrome, childhood disintegrative disorder (CDD), Rett syndrome, and PDD not otherwise specified (PDD-NOS).
Pronunciation: /pərˈvāsiv dēvələpməntəl ˈdisôrdər/
Etymology: The term "Pervasive Developmental Disorder" is derived from the English language. "Pervasive" means spreading widely throughout an area or a group of people. "Developmental" refers to the process of developing or growing. "Disorder" is a state of confusion or a disruption to regular order or functioning.
Symptoms and Diagnosis
The symptoms of Pervasive Developmental Disorder can vary widely but may include difficulties with social interaction, problems with verbal and nonverbal communication, and repetitive behaviors or narrow, obsessive interests. Diagnosis is typically made by a specialist in Child Psychiatry or Pediatric Neurology based on observation and assessment of the child's behavior and development.
Treatment
While there is no cure for Pervasive Developmental Disorder, treatments can often improve a person's functioning. Treatments include Behavioral Therapy, Speech Therapy, Occupational Therapy, and in some cases, medication.
