Abstract

Purpose: Frontal lobe seizures are second in frequency to temporal lobe seizure. The frequency of frontal lobe seizures may be underestimated, as they often are not correctly identified and many are unfamiliar with their clinical characteristics in children. We studied to correlate clinical manifestations with interictal electroencephalographic spike activities in the children of frontal lobe epilepsy.
Methods: We studied the characteristics of children with frontal lobe epilepsies showing interictal abnormalities on electroencephalography(EEG). The clinical characteristics included seizure characteristics, mental retardation, speech and motor delay and methods of medication.
Result: In 79 children manifesting electroencephalographic paroxysmal activities at the frontal area, 60 children had generalized seizures(46 generalized tonic clonic or generalized tonic seizures, 14 absence or atonic seizures) and 19 partial seizure disorders. 51 children was showed spike waves, 16 children was showed spike and waves, 9 children was showed slow waves and 3 children was shows polyspikes. Effect of medication was poor in children with specific etiology, absence seizure, or spike and slow waves in scalp EEC.
Conclusions: Reliability of electroencephalographic abnormalities in frontal area to predict clinical type of seizure is limited. Epileptic children with frontal lobe epilepsy have characteristics of both partial and generalized seizure.
