Vagus Nerve Stimulation (VNS) is an implanted treatment that uses gentle, intermittent electrical pulses to stimulate the vagus nerve, one of the body's main communication pathways between the brain and the rest of the body. VNS is FDA approved for some people with chronic or recurrent depression who have not responded to multiple antidepressant treatments. At Butler Hospital, VNS may be an option for eligible patients through the BRaIN Program after a careful clinical evaluation and coordination with specialty partners.

VNS uses a small device that's implanted under the skin in the chest and connected to the left vagus nerve in the neck. Once the device is activated and programmed, it sends gentle, intermittent electrical pulses that are intended to help regulate the brain networks involved in mood. Unlike Transcranial Magnetic Stimulation (TMS) or Electroconvulsive Therapy (ECT), VNS is designed as a long-term treatment rather than a series of office-based sessions.
VNS may be an option for adults with chronic or recurrent depression who have not improved after multiple evidence-based treatments. It is not the right choice for everyone, especially people with certain medical or surgical conditions that may make the procedure unsafe. Insurance coverage for depression treatment can also be complex and may depend on your health plan, coverage requirements, participation in a study, and documentation of previous treatments.
Your evaluation will include a review of your mental health history, past medication and psychotherapy treatments, previous neuromodulation treatments, medical history, and treatment goals. If VNS appears to be an appropriate option, the BRaIN team will coordinate the next steps with procedural or surgical partners and your outpatient treatment team. After the device is implanted and activated, you'll have follow-up programming visits to adjust the settings over time.
Insurance coverage for VNS to treat depression is more complex than coverage for treatments like TMS or ECT. Medicare coverage for treatment-resistant depression has historically been limited to Coverage with Evidence Development settings, and coverage through commercial insurance plans may vary. The BRaIN team will verify your insurance requirements before presenting VNS as a routine covered treatment option.
No. Vagus Nerve Stimulation (VNS) is different from TMS and ECT. VNS uses an implanted device to send gentle electrical pulses to the vagus nerve, which communicates with areas of the brain involved in mood regulation. TMS is a noninvasive treatment that uses magnetic pulses delivered from outside the head. ECT is a procedure performed under anesthesia that uses controlled electrical stimulation to produce a therapeutic seizure.
Yes. VNS requires a surgical procedure to place a small device under the skin, usually in the chest. A thin wire connects the device to the vagus nerve in the neck. After the device is implanted, your care team will program it and adjust the stimulation settings over time.
VNS is designed as a long-term treatment. Some people may notice improvement within several months, while others may see changes more gradually over time. Because the benefits often build slowly, regular follow-up visits are important to monitor your symptoms and adjust the device settings as needed.
Common side effects may include voice changes or hoarseness, throat discomfort, coughing, shortness of breath, or a tingling sensation when the device is stimulating. These side effects are often related to the stimulation settings and may improve as the settings are adjusted. As with any surgery, there are also risks associated with placing the device, including infection, pain, or bleeding.
Insurance coverage for VNS varies by health plan. Some insurance companies require documentation of previous treatments, medical necessity, and prior authorization before treatment can begin. Our team can help review your benefits and guide you through the insurance approval process.
Many people with a VNS device can still have MRI scans, but special precautions are required. Whether you can have an MRI depends on the type of VNS device you have, the area of the body being scanned, and the MRI settings. Always let your healthcare provider and imaging center know that you have a VNS device before scheduling or having an MRI.
