OCD and Tic Disorder: OCD Behavior Therapy and Causes
The comorbidity with tic disorders suggests interesting pathophysiological and therapeutic implications. In juvenile OCD the rate of tic disorders affects up to 40% of cases and there is a substantial increase in the prevalence of Tourette’s syndrome (TS) among relatives of OCD patients. Tic-related OCD may constitute a separate OCD phenotype, on the basis of symptom profiles, sex ratio, age of onset, family and genetic data, neurochemical and neuroendocrine findings, and patterns of response to treatment.
