Our Neurocritical Care Team at the Intermountain Neurosciences Institute uses the RNS® System, which is a proven treatment option for adults who have disabling seizures that are not controlled by medication. It is a smart device that responds to what's happening in your brain to stop seizures at their source. Once your doctor programs the RNS System to detect and respond to your brain activity, it automatically delivers treatment when you need it. 

What is brain-responsive neurostimulation?

The RNS® System is the only medical device designed to monitor and respond to your brain's electrical activity to prevent seizures before they start. 

  • Implantable device that monitors your brain activity twenty-four hours of the day
  • Detects unusual activity that can lead to a seizure. 

How does the RNS® System work?

Similar to a pacemaker that monitors and responds to heart rhythms, the RNS® System is the first and only medical device that can monitor and respond to brain activity. The RNS® system constantly monitors your brainwaves, detects unusual activity that may lead to a seizure, and responds within milliseconds by sending brief pulse to disrupt this unusual activity. 

Who is a candidate for the RNS® System?

Studies have shown that if you have tried two anti-seizure medications without achieving seizure control, there is a less than 5% chance that your seizures will be controlled by another medication. If you have failed two medications and still suffer from seizures, your doctor will recommend other treatment options, including RNS® System.

What are the potential benefits?

  • Seizure reduction: In clinical studies, patients treated with the RNS® system experience significant seizure reductions that continue to improve over time, achieving 60% seizure reduction at three years and 72% seizure reduction at seven years.
  • Improved quality of life: Patients treated with the RNS® System show no evidence of cognitive decline. In fact, some demonstrated statistically significant improvements in naming and verbal memory. 
  • Positive cognitive impact: Patients treated with the RNS® System show no evidence of cognitive decline. In fact, some demonstrated statistically significant improvements in naming and verbal memory.
