Clinical remission of a treatment-refractory individual with severe repetitive rituals and rumination.

Background: Obsessive-compulsive disorder (OCD) is a severe chronic mental disorder and tends to be refractory to pharmacotherapy or psychotherapy. For treatment-refractory patients, neurosurgical interventions are options. 64 % of OCD patients who undergo neurosurgery still have greater than 16 in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) after a long-term follow-up. Here, we reported a patient living with long-term OCD (20 years) who was refractory to pharmacotherapy, mindfulness-based psychotherapy, and neurosurgery that injured his bilateral anterior cingulates (AC) and caudate nucleus.

Methods: The patient accepted a novel psychotherapy named cognitive-coping therapy (CCT) and completed Y-BOCS, Hamilton depression rating scale, the Hamilton anxiety rating scale, social and occupational function assessment, and resting-state function magnetic resonance imaging scans (rs-fMRI) before and after 4-week CCT.

Results: His Y-BOCS score was reduced from 25 to 4. His depression score and anxiety score were reduced from 19 to 3 and from 12 to 3, respectively. The global assessment of functioning score increased from 32 to 88.

Conclusions: The remission of the patient suggested that CCT could be an alternative intervention for treatment-refractory OCD and those with severe OCD could be cured in short-term.
