Abstract

Obsessive compulsive disorder with child & adolescent onset (C-OCD) is not a rare disorder. Though OCD patients with prepubertal onset is scarce, the prevalence of OCD with postpubertal, adolescent onset reach nearly that of adult OCD. In clinical features, C-OCD resemble adult OCD. However, the other features of pediatric OCD are different from those of adult OCD. The sex ratio of pediatric OCD is male dominant and C-OCD show high comorbid rate with tic disorder, which is not prevailing in adult OCD. Family data analysis of tic disorder and C-OCD reveal the close genetic linkage between two disorders. Neuroimaging studies of C-OCD indicate very consistent findings in basal ganglia volume change (usually reduction of striatum) that may not be so consistent in adult OCD. SSRIs are less effective in C-OCD and combined therapy with antipsychotics is more frequently needed than adult OCD. In conclusion, child and adolescent OCD can be a distinctive subtype of OCD that is different from adult OCD in many ways.
