Interictal EEG topography of frontal lobe epilepsy

Ictal localization of seizure discharges in the frontal lobe is difficult and not easily resolved by simple translation of techniques that have proved useful for localization within the temporal lobe. There is need for improved interictal localization of functional abnormalities within the frontal lobe utilizing CET and other methods of functional localization including magnetoencephalography, cerebral blood flow, and cerebral metabolism. It is likely that improved localization within the frontal lobe and clarification of clinical syndromes of frontal epilepsy will be obtained through the use of a combination of these interictal methods, aided by the results of intracranial ictal recording and surgical extirpation (7a,b,10a,b,15a-c).
