What this trial studies

This investigation aims to gather pilot data on the effectiveness of transcutaneous vagal nerve stimulation (tVNS) combined with exposure and response prevention therapy (ERP) for treating obsessive-compulsive disorder (OCD). The study will assess the tolerability of this combined treatment from both therapists and patients, measure its impact on clinical outcomes, and explore brain changes associated with the treatment. Participants will be adults aged 18 to 55 who meet specific criteria for OCD severity. The study will utilize both sham and active tVNS interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 55 with moderate to severe OCD symptoms.

Not a fit: Patients with major neurological conditions or severe medical diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance treatment outcomes for patients with OCD.

How similar studies have performed: While the combination of tVNS and ERP is a novel approach, similar studies have shown promise in enhancing treatment efficacy for various conditions.
