The FDA has approved a new device for people with epilepsy.
The Neuropace System is implanted directly on the skull to detect seizure patterns and then send out tiny electrical impulses to stop a seizure before it starts.
Neurologists say it's not a complete cure, but it can reduce the frequency and severity of seizures.
Patients can use a special laptop and wand to collect data from the device. Their doctor can then use that information to tweak the device remotely if necessary.
Possible sideffects of the system can include infection at the site of the implant. Some patients have also reported seeing flashes of light.
