An under-the-scalp implant can improve monitoring of a person's epilepsy, giving doctors data they need to improve control over seizures, a new pilot study says.
Epilepsy patients must now keep a diary to track their symptoms.
But these self-observations are only right about half the time, researchers found when they compared patients' diaries to tens of thousands of hours of brainwave data collected by an implant.
"A small tracker placed under the skin was able to detect seizures far more accurately than the participants themselves," senior researcher Mark Richardson, head of the School of Neuroscience at King's College London in the U.K., said in a news release.
