Childhood disintegrative disorder: A case report

Childhood disintegrative disorder (CDD), is a very rare disorder that is characterized by development of autistic like picture and marked regression following some period (at least two years) of normal development. The condition was first described by Thomas Heller, in 1908, also called as Heller’s syndrome. Typically, the age of onset is 3–4 years, but it can happen any time up to age 10. Case Report: A 6-year-old child brought to the OPD with aggressive behavior, communication problem, repetitive body movements and overactivity since past 18 months. Onset is insidious and progressive. History suggestive of measles four years back and GTCS for two years of age. Since last one and half years there is insidious and progressive regression in developmental milestones which were previously attained at appropriate age. Conclusion: To conclude, the study states the importance to the clinicians about the possibility of the diagnosis of CDD following measles, especially when there is a regression in developmental milestones following normal development.
