VNS Therapy has been shown to significantly enhance the quality of life. Benefits include increased energy, improved relationships with friends and family members, and better ability to function at work and in daily activities. VNS Therapy has been shown to succeed when other antidepressant treatments have not worked or have stopped working. The effectiveness of VNS Therapy improves over time and lasts long term.
VNS Therapy is delivered by a small device that is implanted in the left chest, just under the skin much like a pacemaker. From there, electrical leads are connected through a second incision to the left vagus nerve in the neck. This whole procedure takes about an hour. It's typically done as an outpatient basis.
VNS delivers a small amount of electrical current to the left vagus nerve. The electrical impulses are thought to desynchronize the abnormal electrical brain activity.
