Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 14-65 with drug-resistant focal epilepsy requiring SEEG exploration for presurgical assessment.
✕Probably not a fit
Patients who are pregnant or have experienced surgical complications during the implant procedure will not benefit from this study.

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.
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 gone: 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.
