Answers to Your Responsive Neurostimulation (RNS) Questions

Responsive neurostimulation (RNS) is a type of surgery. During the surgery, a small device called a neurostimulator is placed in the skull. It can help to stop epileptic seizures by sending electrical impulses to the part of the brain where the seizure is starting. It works similarly to a pacemaker in the heart. RNS therapy can monitor brain activity and send electrical impulses to the brain to stop seizures.

Before surgery, you will have an epilepsy monitoring unit evaluation. We use this evaluation to find the exact location in the brain where the seizures are located. Using that information, the physician places electrodes where the seizures occur. Then, the neurostimulation device is connected to the electrodes and placed in the skull. 


Once the RNS is implanted, it can detect seizures. It will send electrical impulses to the site to stop the seizure. Once it is programmed, it remains in place to stop seizures as soon as they are detected.


The RNS system comes with a monitor you use at home to wirelessly collect information and then transfer it to the patient data management system. Your doctor can log in to this system to review information about your seizure activity and treatment progress. This helps your doctor learn more about your seizures and improve your care.

RNS can treat epilepsy, multi-focal seizures and well-localized seizures.

The best candidates for RNS are:

  • Patients who have tried at least two anti-seizure medications but still have seizures.

  • Patients who have seizures that come from one or two areas of the brain.

  • Patients who have the ability to use and understand the technology.

You may be able to reduce the amount of medication you take, but your physician will make that decision.

For the first few months, your device will need to be checked monthly. During these check-ups, we will make sure the timing and frequency of the stimulation is correct.

Once your physician thinks the settings are correct, you will only need to visit once every three months.

Every patient has different results with RNS. Many have less frequent seizures. Some are able to go several months with no seizures.

The device is hidden under your scalp. It’s not noticeable to you or other people. Your doctor programs the device so you don’t feel or notice the stimulation.

Most patients go home the day after surgery. Recovery takes two to three weeks.
