Summary

This trial is testing whether VNS Therapy, which sends electrical impulses to the vagus nerve, can reduce depression symptoms in patients who haven't responded to other treatments. The study will observe the effects of VNS therapy over a year. Vagus nerve stimulation (VNS) is a recognized treatment for severe treatment-resistant depression and has shown promising results.

Who is the study for?
This trial is for adults with treatment-resistant depression, which means they've tried at least four different treatments without success. They should be currently in a major depressive episode that's lasted for two years or more, or have had at least four episodes of major depression. Participants must not change their medications for four weeks before getting the VNS device and can't join if they have certain cognitive disorders, a history of rapid cycling bipolar disorder, schizophrenia, other psychotic disorders, or current suicidal thoughts.
What is being tested?
The study is testing whether using Vagus Nerve Stimulation (VNS) as an additional treatment helps reduce symptoms of severe depression compared to no stimulation control after one year. Patients are randomly assigned to either receive active VNS Therapy or be part of the control group that does not receive stimulation.
What are the potential side effects?
Possible side effects from Vagus Nerve Stimulation may include voice changes due to nerve irritation, coughing, sore throat, shortness of breath, tingling sensation in the skin and difficulty swallowing. These side effects vary among individuals.
