Pervasive Developmental Disorder Info

Pervasive developmental disorders (PDDs) are characterized by a delay in a person's communication and social skills -- autism and Rett syndrome are good examples. A PDD typically appears before the age of three (and sometimes as early as infancy). Symptoms will vary, but may include things like:
 
  • Difficulty with changes in routine or familiar surroundings
  • Problems with using and understanding language
  • Difficulty relating to people, objects, and events.
 
Although all the conditions that fall under the term of PDD have some of the same characteristics, they may differ in:
 
  • When the symptoms start
  • How fast they appear
  • How severe the symptoms are.
