Pervasive Developmental Disorder
PERVASIVE DEVELOPMENTAL DISORDERS’
The term “pervasive development disorders,” also called PDDs, refers to a group of
conditions that involve delays in the development of many basic skills, most notably
the ability to socialize with others, to communicate, and to use imagination. In these condition the was confuse in their thinking and generally have problems
understanding the world around them. Because these conditions typically are identified
in children around 3 years of age, a critical period in a child’s development, they are
called developmental disorders. Although the condition begins far earlier than 3 years
of age, parents often do not notice a problem until the child is a toddler who is not
walking, talking, or developing as well as other children of the same age..
The use of the word “pervasive” to describe these illnesses is somewhat misleading.
The definition of pervasive is “to be present throughout,” but children with PDDs
generally do not have problems in all areas of functioning. Rather, most children with
PDDs have specific problem areas and often function very well in other areas.
Children with PDDs, such as autism, can display a wide range of symptoms that can
range in severity from mild to disabling. They also vary widely in their individual
abilities, intelligence, and behavior
