The global vagus nerve stimulation (VNS) market is on a clear upward trend, projected to grow from $488.5 million in 2022 to $836.1 million by 2032, at a CAGR of 5.5%. This growth is being propelled by increasing demand for non-invasive therapies, ongoing technological innovations, and greater awareness of neurological and psychiatric disorders.
What Is Vagus Nerve Stimulation?
Vagus nerve stimulation involves applying mild electrical impulses to the vagus nerve, which runs from the brain to various organs including the heart, lungs, and gut. This therapy helps regulate brain activity and has shown promise in treating several chronic conditions:
✅ Common Conditions Treated by VNS:
Epilepsy, especially drug-resistant cases
Treatment-resistant depression
Migraines and cluster headaches
Inflammatory diseases like rheumatoid arthritis
🔌 VNS Device Types:
Implantable devices (surgically inserted under the skin)
External devices (non-invasive, wearable, or handheld)
