A less invasive brain monitor takes on Epilepsy's hardest seizures
NCT ID NCT07821697
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers are testing whether a minimally invasive electrode placed under the scalp, called subgaleal EEG, can detect seizures as well as the standard approach that places electrodes inside the brain. The study enrolls 15 adults with drug-resistant epilepsy who are already scheduled for inpatient stereoelectroencephalography (SEEG) monitoring. Both recordings run at the same time, and the team compares how well subgaleal EEG identifies seizures, measures signal quality, and locates where seizures start. The goal is to see whether a less invasive method could one day support epilepsy monitoring.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Subgaleal EEG recording, a minimally invasive electrode placed under the scalp to record brain signals
- What this could lead to
- If subgaleal EEG can reliably detect and localize seizures, it could offer a less invasive way to monitor epilepsy than electrodes placed inside the brain.
- What could go wrong
- This is a small, early-stage recording study with only 15 participants, so it may not show that subgaleal EEG is accurate enough. It records signals during a hospital stay and does not test whether the approach improves treatment or outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years or older. * Diagnosis of drug-resistant epilepsy. * Scheduled to undergo clinically indicated inpatient standard-of-care stereoelectroencephalography (SEEG) monitoring. * Able and willing to provide written informed consent. * In the investigator's judgment, able to comply with study procedures. Exclusion Criteria: * Any medical, neurological, psychiatric, or social condition that, in the investigator's judgment, would make participation unsafe or interfere with study procedures or data interpretation. * Active infection, skin condition, or other finding at the planned subgaleal electrode placement site that could increase procedural risk. * Known bleeding disorder, clinically significant coagulopathy, or use of anticoagulant/antiplatelet therapy that cannot be managed per institutional requirements for the planned procedure. * Pregnancy or breastfeeding. * Participation in another investigational study that, in the investigator's judgment, could interfere with TRACE procedures or outcomes.
