Video-telemetry, with EEG recordings from intracranial electrodes, has been used for the past 15 years at the National Center for Epilepsy to identify candidates for epilepsy surgery. The recordings have been a useful tool for correlating neuroanatomy and ictal, epileptic symptoms. The authors describe the most characteristic clinical symptoms and electroencephalographic findings in seizures deriving from the frontal lobe. An attempt is made to subclassify seizures deriving from different parts of the frontal lobe. Frontal lobe seizures are illustrated by three case histories.
