The Fingerprint of Scalp-EEG in Drug-Resistant Frontal Lobe Epilepsies.

ABSTRACT:

Purpose

Scalp-EEG incompletely covers the frontal lobe cortex. Underrepresentation of frontobasal or frontomesial structures, fast ictal spreading, and false lateralization impede scalp-EEG interpretation. Hence, we investigated the significance of scalp-EEG in the presurgical workup of frontal lobe epilepsy.

Methods

Using descriptive statistical methods and Pearson chi-squared test for group comparisons, we retrospectively investigated postsurgical outcome, interictal epileptiform discharges (iiEDs), and electrographic seizure patterns on scalp-EEG in 81 consecutive patients undergoing resective epilepsy surgery within the margins of the frontal lobe.

Results

Postoperatively, patients with frontopolar iiEDs ( n = 7) or concordant frontopolar iiED focus and seizure-on
