MEG vs EEG tests to find the epilepsy trigger before surgery
Part of Brain & nervous system clinical trials.
This study compares two brain tests—MEG and routine scalp EEG—to pinpoint where seizures start before surgery. It may help doctors choose the safest and most effective plan if you’re being considered for an epilepsy procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 60 years old.
- You have had focal (partial) epilepsy for at least 2 years.
- Doctors have already planned that you may need surgery to remove the seizure-start area, either now or after more brain monitoring.
- Your routine scalp EEG should show clear abnormal seizure-signs within the last 2 years (at least 5 abnormal findings in a 20-minute recording).
- You can get an MRI and MEG (no MRI/MEG safety problems like certain metal implants or other contraindications).
- If you could become pregnant, you must have a negative urine pregnancy test at the first visit.

This trial tests a new type of brain scanner (MEG) to help locate the exact area in the brain causing seizures in people with drug-resistant epilepsy. The goal is to improve planning for surgery to remove that area.
This study tests a new “hybrid” type of electrodes placed inside the brain to better map where seizures start in people with difficult (drug-resistant) focal epilepsy. It may help doctors plan safer and more effective surgery, though it involves an invasive brain monitoring procedure.
This study collects noninvasive brain scan data (mainly MRI, sometimes MEG) from people being evaluated for focal epilepsy surgery, and from healthy volunteers. It aims to build reference “normal” brain images and improve how doctors plan and interpret epilepsy surgery evaluations.
This study looks at how to map brain function in people having epilepsy surgery by recording brain signals using special electrodes placed on or inside the brain. It may help doctors better understand which brain areas cause seizures.
This trial uses special MRI scans to create a detailed map of the brain areas causing seizures, helping doctors plan SEEG surgery. It's for people with hard-to-control epilepsy who are already scheduled for SEEG.
This study uses a special kind of brain recording with stimulation to better map seizure activity while you are already having monitoring for epilepsy surgery. It may help doctors understand how to plan safer, more effective treatment.
