Responsive Neurostimulation (RNS)

New Treatment for Seizures

What is Responsive Neurostimulation (RNS)?

LGS is tough. Finding information shouldn’t be. That is why we provide information about this and other medications often used in LGS. We hope you find this information useful as you navigate your LGS journey.

In responsive neurostimulation, a small battery-powered device called a neurostimulator is implanted in the patient’s skull. The neurostimulator is connected to thin wires, called leads, which the surgeon places in the area or areas of the brain where the patient’s seizures originate. The neurostimulator monitors the brain’s electrical activity. When brain activity that could lead to a seizure is detected, the neurostimulator delivers a pulse of electrical stimulation through the leads. The electrical pulse may stop the seizure before it begins.
