Childhood disintegrative disorder, also called CDD, is one of the pervasive developmental disorders (PDD) and a rare condition. PDD are categorized as neurological disorders.
Children with CDD seem to develop normally the first couple of years, but by age 3 or 4 there is a permanent deterioration in both expressive and receptive verbal skills, loss of toilet training skills, motor skills and social withdrawal - not relating with peers. Speaking may become non-existent or reduced to one-word responses.
Though the cause is currently unknown it has been associated with seizure disorders and shows up on an EEG. It appears to be from some defect in the developing nervous system, and it is more common in males.
CDD has been mistaken for autism, which it resembles. But where there may be improvement with autism, the regression in CDD seems to be permanent and supportive care needs to be ongoing.
Parents, may I remind you to get the support you need to maintain your peace of mind and bodily health, to best take care of all your family!
