Treating refractory obsessive-compulsive disorder using real-time functional magnetic resonance imaging
Obsessive compulsive-disorder (OCD) is a chronic psychiatric illness associated with significant morbidity and dysfunction. The therapeutic response to conventional treatments (pharmacotherapy and cognitive-behavioral therapy) is relatively poor compared with that of other mental disorders. Radio and neurosurgical procedures are reserved for severe, treatment-refractory disease that has not responded to treatments. Identifying alternative and non-invasive treatments is a priority. Although the pathophysiology of OCD is unclear, hyperactivity of orbitofrontal cortex (OFC) has been consistently demonstrated. Neurofeedback with real time functional magnetic resonance has been demonstrated as an effective technique to normalize OFC activity in OCD patients. Thus, we propose to investigate the effectiveness of this therapeutic approach in refractory OCD.
