Anterior Versus Posterior Insular Epilepsy: Correlations with Semiology Based on Stereoelectroencephalography.

ABSTRACT:

Objective

To characterize insular seizure semiology and correlate with stereoelectroencephalography (SEEG) seizure onset in a well-defined cohort, in particular examining differences between anterior and posterior insular seizures.

Methods

We documented all semiological signs and the timing of emergence for 45 patients with SEEG-confirmed insular epilepsy, along with the precise location of the seizure onset zone (SOZ) within the insula. Semiological signs and other non-invasive data were compared between those with anterior and posterior insula SOZ, with more detailed insular subregion description when appropriate. Co-occurrence patterns of insular semiological signs were also investigated.

Results

A total of 87% reported auras and the corresponding insular SOZ demon
