New onset left frontal lobe seizure presenting with ictal asystole

Ictal asystole is a presumably rare but potentially fatal complication of seizures, most often of temporal lobe origin. It is believed that at least some cases of sudden unexplained death in epilepsy (SUDEP) might be triggered by ictal bradycardia or asystole. Current standard practice is to implant a permanent pacemaker in these patients to prevent syncope and/or death. However, emerging data ...

Ictal regional cerebral blood flow in frontal lobe seizures

99mTC (single photon emission computed tomography) (HMPAO SPECT) was carried out during 16 frontal-lobe seizures in 15 patients. Focal changes in regional cerebral blood flow were seen during all seizures. In 9 of 16 seizures SPECT showed hyperperfusion localized to one frontal lobe. In 1 of 16 seizures ictal hypoperfusion was seen in one frontal lobe. In 2 of 16 seizures there was hyperperfusi...

Surface ictal electroencephalographic patterns in frontal vs temporal lobe epilepsy.

The effectiveness of long term EEG monitoring in the localization of the epileptic focus was studied in 37 patients with temporal lobe epilepsy comprising 190 recorded seizures, in 19 frontal lobe epileptic patients with 172 recorded seizures and in 12 additional patients which were classified as fronto-temporal. In the temporal lobe group, 49/190 seizures began focally (26%) and 20/190 seizure...
