Responsive Neurostimulation

badge 1

Responsive neurostimulation (RNS) is a device that is placed in a patient’s skull by a pediatric neurosurgeon and connected to the part of the brain responsible for seizure activity. The device is programmed by a pediatric neurologist to detect pre-seizure brain activity and disrupt any abnormal brain seizure activity with electrical impulses to prevent seizures. 

RNS is approved young adults ages 18 and older who have not had success controlling seizures through medication.

Le Bonheur patient Hannah Lawrence sits down with Neuroscience co-director James Wheless, MD, to talk about about responsive neurostimulation (RNS) devices. Lawrence received her RNS device in January 2015.
