Congruence and discrepancy of interictal and ictal EEG with MRI lesions in focal epilepsies

Abstract

The occurrence and localization of interictal and ictal EEG findings differs vastly for lesions in different brain regions. These findings should be used to carefully weigh the results from EEG studies particularly in patients with extratemporal epilepsies considered for epilepsy surgery.

WITHDRAWN: Interiktales EEG bei Epilepsie (Interictal EEG in Epilepsy)

“…verschiedene Aktivierungsmethoden führen zu einer höheren Wahrscheinlichkeit für das Auftreten von ETPs [24]. Bei wenigen M a n u s c r i p t Oberflächen-EEG typischerweise keine ETP aufgezeichnet [26].…”

Mesial Temporal Lobe Epilepsy: A Distinct Electroclinical Subtype of Temporal Lobe Epilepsy

“…These are EEG seizure patterns that have typical rhythmic theta in the temporal regions as in MTLE, but actually represent spread from a distant epileptogenic site that may not be well localized on EEG. One study reported that 11% of patients with an extratemporal MRI lesion had ictal temporal seizure patterns (Remi et al 2011). Pseudotemporal ictal patterns have been reported for nearly all anatomic localizations (i.e., orbitofrontallobe, parietal lobe, occipital lobe, etc.).…”
