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?
The NINDS conducts and supports
research on developmental disabilities, including PDD. Much
of this research focuses on understanding the neurological
basis of PDD and on developing techniques to diagnose,
treat, prevent, and ultimately cure this and similar
disorders.
