What is a responsive neurostimulation (RNS)?

Also known as: RNS® System, RNS, brain-responsive neurostimulation

Responsive neurostimulation is a treatment for epilepsy that is intended to prevent seizures. It does not cure seizures entirely, but it can reduce the frequency and severity of seizures for patients who are not eligible for a focal resection procedure. RNS utilizes a device known as a neurostimulator that is implanted in the patient’s skull and monitors brain electrical activity. When activity that could lead to a seizure is detected, the device delivers a pulse of electrical stimulation to stop the seizure before it begins.
