What this trial studies

This clinical trial evaluates the effectiveness of deep brain stimulation (DBS) in patients with severe and treatment-resistant obsessive-compulsive disorder (OCD). Participants will be randomly assigned to receive either active or sham DBS targeting the bed nucleus of stria terminalis (BNST) for six months. The primary outcome is the reduction of OCD symptoms, while secondary outcomes include changes in anxiety, depressive symptoms, and daily functioning. Following the initial phase, all participants will receive continuous DBS and will be monitored with yearly follow-ups using validated psychometric scales.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with severe OCD who have not benefited from previous treatments, including cognitive behavioral therapy and multiple medications.

Not a fit: Patients with intellectual disabilities or those unable to understand the treatment consequences will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce OCD symptoms in patients who have not responded to traditional therapies.

How similar studies have performed: Other studies have shown promising results with deep brain stimulation for OCD, indicating potential for success in this approach.
