This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a new surgical technique for people with drug-resistant focal epilepsy — a type of epilepsy that hasn't improved with medication. During surgery to remove the part of the brain causing seizures, surgeons will use a high-density flexible micro-electrocorticography device (a thin, flexible sensor that records electrical activity from the brain) to precisely identify and remove only the problematic tissue. The goal is to help more patients become seizure-free after surgery.
Many people with focal epilepsy don't respond to medications alone and need surgery, but identifying the exact area causing seizures can be difficult. This trial exists to see whether the new mapping technology helps surgeons be more precise, leading to better seizure control and fewer side effects after surgery.
You likely qualify if…
You likely don't qualify if…
If you qualify, you would undergo epilepsy surgery with the new high-density brain mapping technology used during the operation to guide the surgeon. The research team would then track your recovery and seizure control after surgery to see how well the new technique works. You would likely have follow-up visits and assessments over several months to evaluate the success of the surgery and your overall outcome.
