GARD Fact Sheet


Pervasive Developmental Disorder-

Not Otherwise Specified (PDD-NOS)

PDD-NOS is an abbreviation for Pervasive Developmental Disorder Not Otherwise
Specified. It is one of five disorders classified as Pervasive Developmental Disorders
(others include Autistic Disorder, Asperger's Disorder, Rett's Disorder and Childhood
Disintegrative Disorder).
The diagnosis PDD-NOS is usually given to an individual who does not meet the
diagnostic criteria for any of the four other Pervasive Developmental Disorders, yet
clearly shows unusual development in the areas of communication, social interaction
and interests/attention.
PDD-NOS is a neurological disorder, and symptoms can range from mild to severe.
Often, individuals with a PDD-NOS diagnosis have more intact social skills than
individuals diagnosed with other Pervasive Developmental Disorders. Sometimes this
diagnosis is given to very young children with limited communication skills who also
show characteristics of autism. As the child's communication skills increase, other
symptoms of autism may become more apparent.

Characteristics
No two individuals diagnosed with PDD-NOS are exactly alike. However, many
individuals with PDD-NOS have some characteristics in common, such as:
+ Deficits in social behavior
+ Uneven skill development (strengths in some areas and significant delays in others.)
+ Poorly developed speech and language comprehension and skills
+ Difficulty with changes in environment
+ Deficits in nonverbal communication
+ Uncommon responses to taste, sight, sound, smell and touch
+ Repetitive or ritualistic behaviors (i.e., opening and closing doors repeatedly or switching
a light on and off)
+ Unusual likes and dislikes

Causes
The causes of PDD-NOS are still unknown. There is a strong belief in the medical
community that that the disability's origin is genetic and/or biological and affects brain
function, but specific biological mechanisms remain unclear. There is a possibility that more
than one variable could be responsible for the different symptoms that are present in those
individuals with PDD-NOS.
There are no factors in a child's upbringing that are responsible for PDD-NOS. Parents
do not cause PDD-NOS.

Facts
Current estimates are that 3-4 per 1000 individuals may have PDD-NOS. PDD-NOS
often occurs with some degree of cognitive impairment. Individuals with PDD-NOS are
found in all races, ethnicities, and social statues.

Journal of the American Medical Association, Vol. 285, 24, 3093.







Treatment
Treatment and educational needs for individuals with PDD-
NOS include but are not limited to:
1.An early and accurate diagnosis, which improves a child's
chances of reaching his or her full potential.
2. Specialized and intensive interventions, which may include
educational, behavioral, occupational and speech therapy.
Success is optimized when a collaborative effort occurs among
all parties involved in the individual's life and a comprehensive
treatment approach is utilized.
