Feasibility Study of Cortical Recording Depolarizations in Brain-injured Patients, and Their Use as Biomarkers of New Lesions.
France20 participantsStarted 2021-01-01
Plain-language summary
The progression of brain lesions after severe head trauma or subarachnoid hemorrhage results from extra cranial aggression which is well controlled in intensive care and intracranial aggression which is less well known and therefore less well managed. The detection of events that can generate new lesions from intracranial monitoring is limited and late once the lesions are irreversible. Invasive cortical depolarizations (SD) can be observed using cortical electrodes and an acquisition system having access to the usually filtered DC signal (0 to 1 Hz). SD are observed at the onset of a new attack of the cortex and spread widely away from the site of aggression. During their propagation, SD generate a significant metabolic demand, and can cause ischemic injury, particularly after meningeal or post-traumatic hemorrhage. SDs are therefore both a marker of new lesion and a mechanism of progression of primary lesions. Yet this type of monitoring is only performed in some expert centers around the world. The analysis of the feasibility and safety of the placement of cortical electrodes in this indication is therefore an essential step to study the clinical benefit of individualized management on the basis of this monitoring.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
