Brain imaging duo may sharpen epilepsy surgery targeting
NCT ID NCT03278210
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether combining EEG and fMRI scans can better pinpoint the exact brain area causing seizures in people with drug-resistant focal epilepsy. 102 participants who were already being evaluated for surgery had this extra scan. The goal was to see if the combined scan helps doctors decide who can benefit from surgery and improve outcomes.
