Prevalence of Childhood Disintegrative Disorder.
Peer reviewed Peer reviewed
Fombonne, Eric – Autism: The International Journal of Research and Practice, 2002
A review of 32 epidemiological surveys of autism and pervasive developmental disorders found four surveys yielded estimates for childhood disintegrative disorder (CDD) ranging from 1.1 to 6.4 per 100,000. It is concluded that CDD is very rare and its prevalence is 60 times less than that of autistic disorder. (Contains references.) (Author/CR)
