What this trial studies

This research aims to evaluate a combined treatment approach for depression by using transcutaneous auricular vagus nerve stimulation (taVNS) alongside transcranial magnetic stimulation (TMS). Participants will undergo a screening session followed by six treatment days, where they will receive either taVNS, TMS, or both in a randomized order. The study is conducted in-person at the Institute of Psychiatry in Charleston, South Carolina, and targets individuals who have not responded to traditional antidepressant medications. The goal is to determine if this combined method can more effectively alleviate depressive symptoms compared to each treatment alone.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who are experiencing depression and have either undergone cervical VNS or have tried and failed two antidepressant medications.

Not a fit: Patients with preexisting neurological disorders, significant cognitive impairments, or current suicidal intent may not benefit from this study.

Why it matters

Potential benefit: If successful, this combined treatment could provide a more effective option for patients suffering from depression who have not responded to standard therapies.

How similar studies have performed: While the combination of taVNS and TMS is a novel approach, similar studies exploring each treatment individually have shown promise in alleviating depressive symptoms.
