Postictal electroencephalographic (<scp>EEG</scp>) suppression: A stereo‐<scp>EEG</scp> study of 100 focal to bilateral tonic–clonic seizures

Abstract

SEEG recordings confirm true absence of signal during postictal EEG suppression. PGES is unlikely when both upper limb extension and oral tonicity are absent. We hypothesize that bilateral tonic seizure discharge at bulbar level brainstem regions is associated with the production of oral signs and may relate to mechanisms of PGES.
