5-SENSE Score Validation Study

The purpose of this study is to assess how well a new scoring system called the 5-SENSE score can predict where seizures start in the brain using Stereoelectroencephalography (SEEG). The 5-SENSE Score is a 5-point score based on routine presurgical work-up, designed to assist in predicting whether SEEG can identify a focal seizure onset zone, thereby sparing patients the risk of undergoing this invasive diagnostic procedure.

Inclusion Criteria: * patients aged 15 years or older in whom no direct surgical approach can be offered and who are discussed in the multidisciplinary team discussion * availability of complete non-invasive presurgical work-up (including high-resolution MRI according to the in-center epilepsy protocol, video-telemetry with the recording of a minimum of one habitual clinic and EEG seizure, available as original files for review) Exclusion Criteria: * no telemetry/scalp EEG in center * no protocol MRI in center * subdural/GRID electrodes
