Basic Characteristics

  • Description

Childhood Disintegrative Disorder(CDD) is a rare developmental disorder classified as one of the five disorders under Autism Spectrum Disorders. People with CDD display similar symptoms to autism with social and communicative deficits as well as repetitive behaviors. Some clinicians consider it a low functioning form of autism, but a significant difference is that those with CDD generally reach the hallmarks of normal development without significant delay until a sudden regression or series of regressions in skills. The average onset of regression occurs between 3-4 years of age. CDD can be distinguished from Rett Syndrome by the period of normal development before regression. CDD can be distinguished from autism by the late onset of regression and a much more dramatic loss of skills. Diagnostic criteria for CDD requires an extensive and pronounced losses of motor, language, and social skills, as well as a loss of bowell and bladder control.
