After experiencing a similar episode three weeks later, he went to a doctor and learned he had epilepsy, a neurological disorder caused by
abnormal electrical activity in the brain.
The NeuroPace ® Responsive Neurostimulation (RNS ®) System is an implantable therapeutic device designed to
detect abnormal electrical activity in the brain and respond by delivering imperceptible electrical stimulation to normalize brain activity before an individual experiences seizures.
The RNS System, manufactured by NeuroPace Inc. of Mountain View, Calif., is a responsive stimulation device that's implanted in the skull along with brain electrodes to
detect abnormal electrical activity in the brain associated with seizures.
According to MedlinePlus, a seizure in humans is defined as «the physical findings or changes in behavior that occur after an episode
of abnormal electrical activity in the brain.»
The device essentially «reboots» the portion of the brain where the seizure is originating, thereby effectively interrupting
the abnormal electrical activity before it spreads or causes its unwanted effects.
The team was also able to reverse
the abnormal electrical activity associated with the fragile X syndrome.
Focal seizures are due to
abnormal electrical activity in one localized part of the cerebral cortex.
Epilepsy refers to
abnormal electrical activity in the brain resulting in seizures or convulsions.
The type of seizure produced depends on the location in the brain where
the abnormal electrical activity occurs.
Like seizures,
the abnormal electrical activity responsible for heart arrhythmias can have a number of causes, including genetic, with some breeds predisposed to them.
