Epilepsy affects 3 million people in the US, making it the third most common neurological disorder in the country. In a move that may offer relief for some patients, the FDA has approved a skull implant that helps reduce the frequency of seizures in patients with drug-resistant epilepsy.
The device is known as an RNS Stimulator, a neurotransmitter that sends electrical impulses to areas of the brain where seizures are believed to originate. Seizures occur when groups of neurons fire abnormally. This device is able to detect when seizure-causing electrical signals are happening in the brain, and fires impulses of its own in order to help regulate brain activity.
