Abstract
Introduction: Up to the early 1980s, obsessive–compulsive disorder (OCD) was considered a rare (less than 0.5%) treatment-refractory, chronic condition of psychological origin. Dynamic psychotherapy was widely used and yet had little benefit; this was also the case for pharmacological interventions [1].The observation that clomipramine, a tricyclic drug for depression with a serotonergic profile, is effective in treating symptoms of OCD [2, 3] has increased clinical interest in this disorder, including its epidemiology; several researchers have since reported a prevalence of OCD of about 2% in the general population [4, 5]. However, changes to the diagnostic system, especially the addition of OCD-related disorders (OCRDs) to OCD (and creating the OCRD cluster) [6], have dramatically increased the calculated prevalence of this cluster to close to 9%.
