Statistics on Childhood Disintegrative Disorder

Unlike autism, childhood disintegrative disorder (CDD) is not a common disease. In 100,000 children, there is only 1 who has CDD and may possibility be under-diagnosed. Before, it is said that CDD occurred equally in boys and girls, but a recent study shows that it is more common in boys than in girls. It is four times more likely to occur in boys; while girls who are diagnosed with CDD in fact have Rett's disorder, which has almost the same symptoms as CDD. 13

  • There are approximately 20% of children who are diagnosed with childhood disintegrative disorder, acquire the skill in speaking again, especially in sentences. 14
  • Childhood disintegrative disorder is a rare condition and it is possibly 10 times less common than more strictly defined autism. 15
  • CDD is a very rare disorder that occur in less than 5 in 10,000 children in the United States. 15
