What is CDD: Childhood Disintegrative Disorder?

    CDD is, in brief, a later-developing form of autism. After an average of 3 to 4 years of normal development, complete with warm social connection and blossoming language, a child, whether slowly or abruptly, loses much that had been gained: social engagement, words and sentences, play skills, sometimes even bowel or bladder control. By the time this regression is over, the child may look very much the same as a child with autism and some degree of mental retardation.
