Devices for Treating Seizures
Seizure medicines do not control seizures or can cause bothersome side effects in at least 3 out of 10 people with epilepsy. For some of these people, surgery may be possible to remove the area of the brain causing the seizures. For others, surgery is not an option or they may not want it at this point. Neuromodulation for epilepsy is another option.
Neuromodulation involves using a device to send small electric currents to the nervous system. This type of therapy:
- Electrical stimulation using implanted devices began in the 1980s.
- When used in epilepsy, a neuromodulation device sends an electrical signal to change what a nerve or the brain does. The purpose is to make the brain cells work the way they are supposed to.
- Each device may work differently. In general, stimulating nerve cells can release substances that change how the cells act or help them go back to their normal state.
Devices and therapy approaches to reduce seizures include:
- Vagus nerve stimulation (VNS Therapy®)
- Responsive neurostimulation (RNS® Therapy)
- Deep brain stimulation
- External trigeminal nerve stimulation
