Early Childhood Intervention: Module Two – Special Needs & Conditions

Children with Pervasive Developmental Disorders (PDD)

The Early Intervention Dictionary describes “Pervasive developmental disorders” (PDD)1 as an “umbrella” term.

It is important for physicians and others in the medical and health professions to learn about the early signs of PDD.  This way they can work with parents and begin a referral process in order to assess and either rule out or confirm the PDD diagnosis between the ages of 2 and 3 years2, as opposed to waiting until the age of 5 years.

To learn about PDD in the middle childhood years, please visit the six to 12 part of this course.
