Investigating brain activity in epilepsy patients using implanted electrodes

Multi-level Approach of Brain Activity Using Intracranial Electrodes in Epileptic Patients

Not applicable Interventional Institut National de la Santé Et de la Recherche Médicale, France · NCT04653012

This study is testing how brain activity in patients with hard-to-treat epilepsy can help us understand their seizures and how it affects their thinking and sleep.

What this trial studies

This project aims to explore the mechanisms of epileptic activities by utilizing both macro and micro intracranial electrodes in patients with focal drug-resistant epilepsy who are undergoing pre-surgical evaluation. The study will involve recording brain activity to gain insights into physiological processes such as sleep and cognitive functions. By analyzing these recordings, researchers hope to better understand the neurophysiology of epilepsy and its impact on cognitive abilities.

Who should consider this trial

Good fit: Ideal candidates include adults with focal drug-resistant epilepsy who are undergoing presurgical evaluation with intracranial electrodes.

Not a fit: Patients with contraindications for intracranial investigations or those who are pregnant, breastfeeding, or minors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with drug-resistant epilepsy.

How similar studies have performed: Other studies using similar intracranial electrode approaches have shown promise in understanding epilepsy, but this specific multi-level approach is relatively novel.
