title: Obsessive-compulsive disorder in Tourette syndrome.
abstract: Several lines of evidence suggest a meaningful association between obsessive-compulsive disorder and Tourette syndrome, including comorbidity, phenomenologic overlap, evidence from family and genetic studies, and the possible role of basal ganglia circuitry in both conditions. Obsessive-compulsive behaviors occur frequently in patients who have Tourette syndrome and tend to have a later onset than tics. Despite commonalities, the approaches to treating tics and obsessive-compulsive symptoms are actually quite distinct. A specialized form of cognitive behavior therapy and pharmacotherapy with a potent serotonin reuptake inhibitor are the two established first-line therapies for obsessive-compulsive disorder. An adequate trial of a serotonin reuptake inhibitor is 10 to 12 weeks in duration at doses near the upper end of the recommended range for age and weight. Cases of obsessive-compulsive disorder that do not sufficiently improve with serotonin reuptake inhibitors might benefit from adjunctive low-dose antipsychotic (eg, risperidone) medication whether or not tics are present. Warnings about an increased risk of suicidality among children and adolescents taking antidepressants for pediatric depression extend to those taking the medications for obsessive-compulsive disorder, but the risk-to-benefit ratio is more favorable in this latter population because several serotonin reuptake inhibitors have been shown to be efficacious in obsessive-compulsive disorder.
