Clinical treatment of OCD is mainly based on pharmacotherapy and psychotherapy. Pharmacological treatment is currently used in clinical practice mainly to treat systematically with 5-hydroxytryptamine reuptake inhibitors, such as paroxetine, sertraline, fluvoxamine and other drugs in sufficient amounts and courses, and the dosage of their application should be sufficient to control the symptoms of OCD during treatment. Psychotherapy is also a very effective means of OCD treatment, especially the exposure and response prevention method, the core essence of which is to interrupt the pattern of compulsive behavior when the patient is experiencing pain due to compulsive thinking, which can be relieved by compulsive behavior itself, and expose the patient to the anxiety caused by compulsive thinking, which can be relieved when the anxiety reaches its peak, and through this treatment method to help Patients get effective relief. In addition, Morita therapy is also a very effective treatment method in the clinical treatment process. When compulsive thinking arises, let nature take its course and do not interfere, but do what you want to do at the moment, without using compulsive behavior to relieve anxiety. This is the core point of both psychotherapeutic approaches.
