Pervasive developmental disorders or PDD are those conditions due to which the developments of many basic skills in children are delayed. These children face problems in socializing with others, in using their creativity and their imagination. They face many difficulties in understanding the world around them due to their problems of thinking and communication. Pervasive developmental disorders or PDDs are also known as developmental disorders. This is because they usually occur during the developmental phase of a child- around the age of 3 years or so.
Pervasive Developmental Disorder Behavior Inventory (PDDBI)
A pervasive developmental disorder is one of five disorders characterized by deficits or delays in communication and socialization. Symptoms may begin during infancy, but diagnosis usually occurs after the age of three years. These disorders are also called autism spectrum disorders or PDDs. Depending on the specific diagnosis and severity of symptoms, children with PDD vary widely in intellectual, physical, and social abilities.
Pervasive Developmental Disorders: Types, Causes, Symptoms, Treatment, Prognosis
Pervasive developmental disorder PDD includes a few mental disorders which affect the development of communication and social skills in children. This condition is typically noticed by parents before a child is three years old. The main disorders which come under PDD are autism , asperger syndrome, rett syndrome and childhood disintegrative disorder. The symptoms associated with this disorder can vary from child to child.
In fact, people diagnosed with pervasive developmental disorder-not otherwise specified PDD-NOS are no more likely to marry or have a job than those with more disabling forms of autism, according to a Norwegian study published online in June in the Journal of Autism and Developmental Disorders 1. Early intervention has the potential to alter this trajectory, say experts. These findings provide support for the proposed merging of pervasive developmental disorder into the autism spectrum in the DSM-5, the edition of the Diagnostic and Statistical Manual of Mental Disorders DSM set to be published in , the researchers say. The new edition of the manual takes a spectrum approach , absorbing the separate categories of childhood disintegrative disorder, Asperger syndrome and PDD-NOS into the broad category of autism spectrum disorder.
