COMPARISON OF CHILDHOOD DISINTEGRATIVE DISORDER WITH OTHER DISORDERS

Childhood disintegrative disorder is an unusual disorder when compared to other pervasive developmental disorders like Rett’s disease. With CDD, a child can be diagnosed with this disorder if he or she has a normal development for at least 2 years of age and the deterioration of skills acquired are loss before age ten. And these will supported through baby book records, medical records, and home movies that are captured to document the normal development of the child for the first two years. 10

CDD is unlike Landau-Kleffner syndrome (LKS); the onset of the symptoms for LKS are more delayed in age compared with CDD. The beginning of the symptoms is around 5-1/2 years old, while CDD is around 3-4 years. The abnormalities of children with childhood disintegrative disorder is life-long for auditory responsiveness and verbal communication than with pervasive developmental disorder, however, the defect is not as severe in LKS. 11

In addition, CDD and autism is sometimes mistakenly recognized as the same with some of the similar manifestations but there are many differences between the two. The key differences of CDD from autism are normal development of the child up to two to three years of age, loss of skills that were recently learned like language and social skills, unable to control the bladder and bowel, and seizures. Also, compared to autism, childhood disintegrative disorder is more likely to include mental retardation. 12
