Testing New Brain Stimulation Frequencies to Improve Epilepsy Surgery Planning

This trial is testing whether using a wider range of electrical stimulation frequencies during a standard brain monitoring procedure can help doctors more accurately identify where seizures begin in people whose epilepsy doesn't respond well to medication. Right now, doctors typically use only two standard frequencies when stimulating the brain during this monitoring. The study will compare results from the standard frequencies against results from new, additional frequencies chosen based on each patient's own seizure patterns and brain activity.

For people with drug-resistant epilepsy who may benefit from surgery, doctors need to pinpoint exactly where in the brain seizures start. The current approach uses only two standard stimulation frequencies without clear scientific evidence that these are the best choices. This trial aims to see whether testing a broader range of frequencies—tailored to each patient's brain and seizure type—could give doctors a clearer, more accurate picture to guide surgery planning.
