What this trial studies

This study aims to analyze electrophysiological and clinical data from patients aged 14-65 with drug-resistant epilepsy who undergo stereoelectroencephalography (SEEG) to explore the functional characteristics of white matter fibers. By recording brain signals, the study seeks to understand how white matter connectivity changes between wakefulness and sleep. The research focuses on the impact of sleep on brain connectivity and its implications for epilepsy treatment. The findings could provide insights into the neuronal functional states and cortical excitability related to epilepsy.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 14-65 with drug-resistant focal epilepsy requiring SEEG exploration for presurgical assessment.

Not a fit: Patients who are pregnant or have experienced surgical complications during the implant procedure will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of brain connectivity in epilepsy, potentially leading to improved treatment strategies.

How similar studies have performed: While the approach of using SEEG to study white matter connectivity is innovative, similar studies have shown promise in understanding brain function during different states.
