Vagus nerve stimulation (VNS) devices are specialized neuromodulation systems that deliver gentle electrical impulses to the vagus nerve to regulate abnormal nerve activity and enhance communication between the brain and the body’s organs. This therapy is designed to improve neurological function and provide long-term symptom relief for patients with chronic neurological and psychiatric disorders.
Widely used for the treatment of drug-resistant epilepsy and treatment-resistant depression, VNS technology is also being investigated for additional applications, including stroke rehabilitation, chronic migraine, anxiety disorders, and other conditions involving autonomic nervous system dysfunction. Available as both implantable and non-invasive external devices, VNS systems offer clinicians flexible treatment options that can complement or reduce reliance on conventional drug therapies while improving patients’ quality of life.
