Complex partial seizures of frontal lobe origin

Authors


Abstract

Complex partial seizures of medial or orbital frontal origin were documented in 10 of 90 patients with intractable epilepsy who were studied with depth electrodes. The clinical features that, in part, served to distinguish these seizures from complex partial seizures originating elsewhere included brief, frequent attacks, complex motor automatisms with kicking and thrashing, sexual automatisms, vocalization, and frequent development of complex partial status epilepticus. The constellation of clinical characteristics was often bizarre, leading to the erroneous diagnosis of hysteria. Stereotyped attack patterns helped establish the diagnosis of epilepsy. Interictal and ictal scalp electroencephalograms were often not helpful and were sometimes misleading.
