Research has also shown that vagus nerve stimulation could be effective for treating psychiatric conditions that don’t respond to medication. The FDA has approved vagus nerve stimulation for treatment-resistant depression and for cluster headaches.

Because the vagus nerve influences the immune system, damage to the nerve may have a role in autoimmune and other disorders.
