Vagus Nerve Stimulation For Anxiety – A Complete Guide

Vagus Nerve Stimulation For Anxiety

Anxiety disorders are a common mental health condition that can significantly impact an individual’s quality of life. There are various treatment options available for anxiety disorders, such as medication and psychotherapy. However, some people may not respond well to these treatments or experience significant side effects. Vagus nerve stimulation (VNS) has emerged as a potential treatment option for anxiety. This blog will explore the benefits, risks, and current state of research on VNS for anxiety.

What Is Vagus Nerve Stimulation?

Vagus nerve stimulation (VNS) is a medical treatment that involves the use of a device that sends electrical signals to the vagus nerve, which is a long nerve that runs from the brain to the abdomen. The electrical signals are intended to improve communication between the brain and the rest of the body.

This can have a variety of therapeutic effects. VNS has been used to treat a number of conditions, including epilepsy, depression, and migraines. The device is typically implanted under the skin in the chest and connected to the Vagus nerve in the neck, where it can be activated by a handheld magnet.

Procedure Of Vagus Nerve Stimulation

Given below is a step-by-step procedure followed in Vagus Nerve Stimulation for anxiety:


The evaluation process involves a comprehensive medical examination. It includes a review of your medical history, physical examination, and diagnostic tests. The healthcare professional will evaluate your symptoms. Also, he will determine whether vagus nerve stimulation is a suitable treatment option for you.


The implantation of the vagus nerve stimulation device is usually performed under general anesthesia. A small incision is made in the chest, and the device is placed under the skin, usually near the collarbone. A wire, or lead, is then attached to the device and threaded up to the neck, where it is wrapped around the vagus nerve.


After the device is implanted, it must be programmed to deliver the appropriate electrical signals to the vagus nerve. This is typically done by a healthcare professional using a handheld programmer. The settings on the device can be adjusted to optimize the therapy.


Once the device is programmed, it can be activated using a handheld magnet. The magnet is held over the device to activate it. The device will then deliver the electrical signals to the vagus nerve. The therapy is generally delivered for a set period each day, typically several minutes at a time.

Monitoring and adjustments

The device is monitored regularly to ensure that it is functioning correctly and delivering the appropriate level of electrical stimulation. Adjustments may need to be made to the device settings over time to optimize its effectiveness. You may need to have your device checked and adjusted every few months.

Follow-up care

Regular follow-up care is essential to ensure that the device is continuing to provide the desired therapeutic effects and to address any issues or concerns that may arise. You may need to have regular appointments with your healthcare provider to monitor the device’s function and adjust the therapy settings as necessary. In addition, you may need to have the device replaced every few years when the battery runs out.

Is Vagus Nerve Stimulation For Anxiety?

Vagus nerve stimulation for anxiety has been studied as a potential treatment, but it is not currently FDA-approved as a standalone treatment for anxiety disorders. However, VNS has been approved by the FDA for the treatment of certain medical conditions, like epilepsy and depression. Hence, more research is needed to establish the efficacy and safety of VNS specifically for the treatment of anxiety disorders.

In some cases, healthcare professionals may consider VNS as an adjunctive therapy for anxiety disorders in combination with other treatments, such as medication and psychotherapy. However, the decision to use VNS for anxiety should be made on a case-by-case basis after a thorough evaluation of the individual’s medical history, symptoms, and treatment options.

Benefits Of Vagus Nerve Stimulation

Vagus nerve stimulation (VNS) has been studied as a potential treatment for several medical conditions, and it may offer several potential benefits, including:

  • Epilepsy Control: VNS is effective in reducing the frequency and severity of seizures in people with epilepsy who have not responded to other treatments.
  • Depression Management: VNS has been approved by the FDA as an adjunctive therapy for treatment-resistant depression. Studies have shown that VNS may improve mood, and reduce anxiety and stress. It also enhances cognitive function in people with depression.
  • Migraine Relief: VNS has been studied as a potential treatment for chronic migraines. Early studies have suggested that it may reduce the frequency and intensity of migraine attacks.
  • Reduced inflammation: VNS may also help reduce inflammation in the body, which has been linked to a variety of health problems, including autoimmune diseases and chronic pain conditions.
  • Improved Heart Health: VNS may also improve heart health by reducing inflammation, regulating heart rate variability, and reducing the risk of heart failure.
  • Treatment of other disorders: VNS has also been studied as a potential treatment for several other medical conditions, including anxiety disorders, post-traumatic stress disorder (PTSD), and Alzheimer’s disease.

Side Effects Of Vagus Nerve Stimulation

Vagus nerve stimulation (VNS) is generally considered a safe and well-tolerated treatment, but like any medical procedure, it does carry some potential side effects. Here are some common side effects associated with VNS:

  • Voice changes: VNS can cause hoarseness or changes in the tone or quality of your voice. This is because the vagus nerve is involved in controlling the vocal cords.
  • Neck pain: Some people may experience mild to moderate neck pain or discomfort following VNS implantation.
  • Coughing: VNS can sometimes trigger a coughing reflex, especially during the initial activation period.
  • Difficulty swallowing: In rare cases, VNS can cause difficulty swallowing due to stimulation of the vagus nerve, which controls muscles involved in swallowing.
  • Headache: Some people may experience headaches or migraines following VNS.
  • Nausea: Nausea is a potential side effect of VNS, especially during the initial activation period.
  • Skin irritation: The skin around the implanted device may become irritated or inflamed.
  • Seizures: While VNS is typically used to treat seizures, it can occasionally trigger seizures, especially if the stimulation settings are too high.
  • Mood changes: VNS has been associated with changes in mood or behavior in some people, although these effects are generally mild and may resolve over time.


In conclusion, Vagus Nerve Stimulation for anxiety is not currently FDA-approved as a standalone treatment. However, it has shown promising results in reducing anxiety symptoms in individuals with comorbid conditions such as depression and epilepsy. VNS is a safe and well-tolerated treatment option that may offer several potential benefits, including mood improvement and reduced inflammation, but more research is needed to establish its efficacy and safety specifically for the treatment of anxiety disorders.
