Childhood disintegrative disorder is a condition occurring in 3- and 4-year-olds who have developed normally to age 2. Over several months, a child with this disorder will deteriorate in intellectual, social, and language functioning from previously normal behavior.

Disintegrative psychosis; Heller syndrome

The cause of childhood disintegrative disorder is unknown, but it has been linked to neurological problems. An affected child shows a loss of communication skills, has regression in nonverbal behaviors, and significant loss of previously acquired skills. The condition is similar to autistic disorder (autism).
