RNS for Epilepsy Has Long-Term Benefits
More than half of epilepsy patients treated with the recently approved responsive neurostimulation device (RNS) had reductions of 50% from baseline in seizure frequency lasting for up to 80 months, researchers reported here.
Among 250 participants in the pivotal trial of the implanted RNS System neurostimulator, approved last month for treating drug-resistant focal epilepsy, long-term follow-up indicated that responder rates increased steadily over the first 2 to 3 years after implant, reaching about 55%, said Martha Morrell, MD, chief medical officer of NeuroPace, based in Mountain View, Calif., which manufactures the device.
