With CDD, there is also the possibility of mental retardation. Fortunately, Childhood Disintegrative Disorder is rarer than autism.

Rett syndrome is a developmental disorder which was first known in infancy and is almost always seen in girls. Rett syndrome symptoms beginning to appear earlier than on classic autism, Asperger's Syndrome and Childhood Disintegrative Disorder, usually begins right after normal development until the age of six to eighteen months. At this point, the baby's skills seem to slow down or stop and then, he actually lost that particular skill which previously he had.
