Autism spectrum disorder - childhood disintegrative disorder

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

Childhood disintegrative disorder is a part of the larger developmental disorder category of autism spectrum disorder.
