A Retrospective Study to Validate BioEP as an Assessment Aid for Seizure Susceptibility

The goal of this retrospective study is to validate BioEP during routine adult EEG recording in an outpatient setting, using patients with a known epilepsy diagnosis. The main objectives of the study are: * To validate BioEP during routine adult EEG recording in an outpatient setting, using patients with a known diagnosis * To examine whether the use of BioEP could support a more efficient patient pathway to diagnosis (thus adding economic value), by reducing time to final diagnosis and/or the number of clinical appointments needed.
