What are Pervasive Developmental Disorders?
The diagnostic category of pervasive developmental disorders
(PDD) refers to a group of disorders characterized by delays in
the development of socialization and communication skills.
Parents may note symptoms as early as infancy, although the
typical age of onset is before 3 years of age. Symptoms may
include problems with using and understanding language;
difficulty relating to people, objects, and events; unusual play
with toys and other objects; difficulty with changes in routine
or familiar surroundings, and repetitive body movements or
behavior patterns. Autism (a developmental brain disorder
characterized by impaired social interaction and communication
skills, and a limited range of activities and interests) is the
most characteristic and best studied PDD. Other types of PDD
include Asperger's Syndrome, Childhood Disintegrative Disorder,
and Rett's Syndrome. Children with PDD vary widely in abilities,
intelligence, and behaviors. Some children do not speak at all,
others speak in limited phrases or conversations, and some have
relatively normal language development. Repetitive play skills
and limited social skills are generally evident. Unusual
responses to sensory information, such as loud noises and
lights, are also common.
Is there any treatment?
There is no known cure for PDD. Medications are used to address
specific behavioral problems; therapy for children with PDD
should be specialized according to need. Some children with PDD
benefit from specialized classrooms in which the class size is
small and instruction is given on a one-to-one basis. Others
function well in standard special education classes or regular
classes with additional support.
What is the prognosis?
Early intervention including appropriate and specialized
educational programs and support services plays a critical role
in improving the outcome of individuals with PDD. PDD is not
fatal and does not affect normal life expectancy.
What research is being done?
