Childhood disintegrative disorder is a condition in which children develop normally through age 3 or 4. Then, over a few months, children lose language, motor, social, and other skills that they already learned.

Disintegrative psychosis; Heller syndrome

The cause of childhood disintegrative disorder is unknown, but it has been linked to brain and nervous system problems. A child who is affected loses:

• Communication skills
• Nonverbal behaviors
• Skills they had already learned

The condition is similar to autistic disorder (autism).
