A variety of clinical syndromes exist depending on the exact localization of seizures and clinical semiology of the seizure type. Frontal lobe epilepsies have been divided into several specific syndromes including the syndrome of supplementary motor seizures, cingulate seizures, anterior frontal polar region seizures, orbital frontal seizures, dorsolateral seizures, opercular seizures, and seizures of the motor cortex.
