Complex partial seizures (CPSs) of extratemporal origin are frequently misdiagnosed. Common reasons for diagnostic errors are failure to recognize the epileptic cause of the attacks or to appreciate localizing clinical seizure characteristics and nonspecific or misleading scalp EEG findings. This report describes clinical characteristics of two types of extratemporal CPSs, frontal and occipital. Frontal lobe CPSs are brief, frequent attacks that begin and end suddenly. They are dominated by complex, semi-purposeful motor automatisms, and vocalization and sexual automatisms are common. Their often bizarre appearance frequently leads to a misdiagnosis of hysteria. Occipital lobe CPSs are characterized primarily by their spread pattern, which can follow various paths. They may mimic temporal lobe CPSs, sensorimotor partial seizures, or supplementary motor partial seizures. Scalp EEGs are frequently misleading. The initial clinical symptoms are the most important clue to correct diagnosis and include elemental visual symptoms, visual loss, eye pulling or movement sensations in the absence of detectable movement, rapid forced blinking or eye flutter, and contralateral eye deviation.

Ictal sexual automatisms such as masturbatory activity, pelvic thrusting, or similar automatisms for which the patient is amnesic have been attributed to temporal lobe disease. Of 61 patients with medically refractory complex partial seizures, 14 had frontal lobe seizure foci. Four of these patients manifested sexual automatisms in some or all of their seizures. Frontal lobe seizure origin was documented by depth EEG in three patients. In the fourth, a calcified lesion was demonstrated radiologically. In three patients, frontal lobectomy revealed abnormal frontal lobe pathology and was followed by 75 to 100% reduction in seizure frequency. Sexual automatisms did not occur in patients with seizures originating in any area other than the frontal lobe.
