What Is Pervasive Development Disorder?

Pervasive development disorder refers to a range of conditions that affect socialization and communication skills. The disorders---which may manifest through a wide array of symptoms---usually become apparent before the age of three.

Symptoms

• Symptoms of a pervasive development disorder include playing with toys in an unusual manner, difficulty with language, limited social skills and repetitive movements or behaviors, according to the National Institute of Neurological Disorders and Stroke.

Condition Spectrum

• The range of conditions that fall within the category of pervasive development disorder include Asperger's Syndrome, childhood disintegrative disorder, Rett's Syndrome and autism, according to the Autism Society.

Diagnosis

• A developmental screening during a routine check-up should be done to check for a pervasive development disorder. A comprehensive diagnostic evaluation, completed by a team of professionals, is the next step in diagnosis, according to the National Institute of Mental Health.

Treatment

• Treatment varies according to the specific condition within the spectrum of pervasive development disorder, but options generally include medication, language and behavior therapy or individualized instruction in school, according to the National Institute of Neurological Disorders and Stroke.

Prognosis

• Life expectancy is not impacted by a pervasive development disorder, according to the National Institute of Neurological Disorders and Stroke. Early intervention and therapy is key to successful treatment.
