Musical OCD is not a medical term; it is a form of OCD from a professional perspective. Effective treatment methods for OCD include medication and psychotherapy, as follows: 1. Medication is the main treatment method for OCD. Medication includes three treatment phases: the acute phase, the consolidation phase and the maintenance phase, calling it a full course of treatment. Medication is generally chosen from the first-line drugs, first-line drugs refer to selective 5-hydroxytryptamine reuptake inhibitors, also called SSRI drugs, such as fluoxetine, fluvoxamine, sertraline, paroxetine, citalopram. Medication needs to be adequate, full course and full treatment; 2. Psychotherapy. The onset of OCD is closely related to pre-morbid personality, personal life experience, psychosocial factors, trauma, etc. It is sometimes difficult to achieve satisfactory results with medication alone. Currently, the main psychological treatments for OCD include behavioral therapy, psychoanalytic approach, cognitive therapy, cognitive behavioral therapy, Morita therapy and supportive psychotherapy. Psychotherapy is recommended to be performed regularly in a treatment room under the guidance of a psychotherapist. 3. Physical therapy methods, such as transcranial magnetic stimulation, electroconvulsive therapy, deep brain stimulation, vagus nerve stimulation, etc., but the efficacy is often less precise and therefore physical therapy is not advocated as the main treatment method. Therefore, for most patients with OCD, medication and psychotherapy are advocated to be carried out simultaneously and successively, as they are more effective than any treatment alone.
