Obsessive-compulsive disorder (OCD) is a relatively common disorder, most of the time under diagnosed and under treated despite the existence of effective treatments. OCD can be discriminated from other disorders, having obsessive or compulsive features on the basis of obsession content or the characteristics of the compulsions. Selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT) seem to be proven treatments for OCD. They cause a significant reduction in symptoms, although complete remission in clinical cases is not seen commonly. Long-term drug treatment with cognitive behavioral therapy has shown better results than drug alone.
