Nerve Stimulation for Migraine
The world of migraine treatment is constantly evolving, offering new hope and new options for those living with this complex disease. One of the most exciting and rapidly growing areas of treatment is neuromodulation—the use of gentle electrical or magnetic pulses to alter nerve activity. For many people who are looking for effective, drug-free options, nerve stimulation devices can be a transformative part of their treatment plan. It can sound like science fiction, but the science is real and the relief it can provide is significant. This guide is here to offer a gentle and clear introduction to the world of nerve stimulation for migraine.
How Does Neuromodulation Work?
The underlying principle of neuromodulation is simple: a migraine is a neurological event, so by directly influencing the nerves involved in the migraine process, we can help to stop an attack or prevent it from starting. These devices work by delivering targeted energy to specific nerves, which helps to calm them down and disrupt the pain signals being sent to the brain. It’s like turning down the volume on an overactive nervous system.
There are now several FDA-cleared neuromodulation devices available for both acute and preventive treatment of migraine.
Types of Nerve Stimulation Devices
1. External Trigeminal Nerve Stimulation (e-TNS)
This is the technology used by the Cefaly device, which we discuss in our article on Migraine Headbands. It is a device worn on the forehead that delivers gentle electrical pulses to the trigeminal nerve, the primary nerve involved in migraine pain. It has settings for both acute treatment (to be used at the start of an attack) and preventive treatment (to be used daily).
2. Non-invasive Vagus Nerve Stimulation (nVNS)
This approach targets the vagus nerve, which is a major information highway between the brain and the body. The gammaCore device is a handheld, non-invasive stimulator that you place on the side of your neck. It delivers a gentle electrical stimulation to the vagus nerve, which can help to calm the nervous system and reduce the severity of an attack. It is cleared for both acute and preventive treatment of migraine.
3. Remote Electrical Neuromodulation (REN)
This is a fascinating approach used by the Nerivio device. It is a wireless armband that you wear on your upper arm at the onset of a migraine attack. It delivers electrical pulses to the nerves in the arm, which then sends a signal to the brainstem to trigger a natural, pain-relieving process. It essentially uses the body's own pain management system to turn off a migraine attack. It is cleared for the acute treatment of migraine.
4. Single-Pulse Transcranial Magnetic Stimulation (sTMS)
This technology uses a magnetic pulse rather than an electrical one. The SAVI Dual device is held at the back of the head and delivers a single magnetic pulse. This is thought to disrupt the wave of brain activity known as cortical spreading depression, which is the cause of migraine aura. It is cleared for both acute and preventive treatment of migraine with aura.
Is Nerve Stimulation Right for You?
Neuromodulation can be an excellent option for many people, especially those who:
-
Cannot tolerate or have not had success with traditional migraine medications.
-
Are looking for effective, drug-free treatment options.
-
Are pregnant or breastfeeding and need to avoid medications.
-
Are at risk of medication overuse headache.
These devices are generally very safe with minimal side effects, but they do require a prescription. It is essential to have a conversation with your doctor or headache specialist to determine if one of these devices is a good fit for your specific situation and treatment goals.
A Final, Compassionate Thought
The development of nerve stimulation devices represents a significant and hopeful shift in migraine care. It acknowledges that migraine is a complex electrical and chemical event and offers a way to gently and directly influence the brain's activity without medication. Exploring these options with your doctor is an empowering step, a way of seeking out the latest, most innovative tools to help you manage your disease and live a fuller life.
