Pervasive Developmental Disorder

A normal child starts babbling when he/she is about 6 months old. By the time his/her first birthday arrives, he/she responds, when name is called out. They also point to toys on their own. But this is not the case with children who are diagnosed with PDD.

PDD or Pervasive Developmental Disorders involves different disorders which are followed by delay in manner of socializing and development of communication skills. Concerned parents usually note the symptoms of this disorder in their infant child. The typical age of its development is after 3 years. It usually has more occurence in boys.

    Children with PDD have different abilities and behaviors. Some dont speak at all, few speak in small and limited phrases, while some have a bit of normal development.
