LATERAL FRONTAL-LOBE SEIZURES

On the basis of cytoarchitectural and functional studies, the frontal lobe can be subdivided into the primary motor cortex, premotor cortex, prefrontal cortex, and the limbic and paralimbic cortices. However, w e are still a long way from clearly identifying individual frontal lob e epilepsies. Instead, we are limited to a discussion of frontal lobe seizures arising from various regions of the frontal lobe. Supplementa ry motor area epilepsy and perirolandic epilepsy have been quite well defined, in contrast to syndromes involving other regions of the front al lobe. Recent technological advances in neuroimaging, electroencepha lography, magnetoencephalography and detailed videotape analysis of se izure semiology may enable us to delineate these frontal lobe syndrome s with better accuracy, thereby improving outcome after epilepsy surge ry.
