1-A-D-25. Ictal limb posturing differs between seizures arising from temporal lobe and supplementary motor area: A video-EEG study

Focal seizures arising from the temporal lobe (TL seizures) resemble those from supplementary motor area (SMA) with resepct to ictal dystonic and/or tonic posturing. The aim of this study is to clarify the symptomatic difference and then underlying mechanism between TL- and SMA seizures by careful observation of ictal posturing. Among patients with partial epilepsy who performed long-term video-EEG monitoring from 1992 to 2014, we employed 13 patients with TL seizures showing discrete dystonic posture and 12 patients with SMA seizures showing clear abnormal tonic posture. We reviewed the posturing and the movement direction of the shoulder, elbow and wrist joints of both seizures. As the results, shoulder adduction was observed significantly more in TL seizures than SMA seizures ( p p
