Semi-automatic interictal electric source localization based on long-term EEG monitoring: a prospective study.

In this prospective study, SAEA of long-term video-EEG, spanning several days, we found excellent localizing information and a high yield, even in difficult patient groups. This compares favorably to HD-ESI, most likely due to marked improved signal-to-noise ratio of the averaged IEDs. We propose to include ESI, or SAEA, in the work-up of all patients who are referred for epilepsy surgery.
