CLINICAL FEATURES OF FOCAL EPILEPSY WITH SECONDARY BILATERAL SYNCHRONIZATION ON EEG AMONG ADOLESCENTS

Abstract

Abstract: current work is dedicated to analysis of features of clinical and encephalographic manifestations of focal epilepsy with secondary bilateral synchronization on EEG and onset in adolescence. The other aim was comparison these findings among patients with onset in adolescents and adult patients. We analyzed data of 66 adolescent patients and 61 adult patients with focal epilepsy with secondary bilateral synchronization on EEG. All patients were investigated with prolonged videoencephalographic monitoring and MRI of the brain. Analysis of types of epileptic seizures was made too. We revealed that etiological factor of focal epilepsy with secondary bilateral synchronization on EEG could not be found in case of onset of epilepsy in adolescence in contrast to epilepsy with onset in adult age. Secondary generalized convulsive seizures with fast generalization, bilateral myoclonic seizures and dialeptic seizures were more appropriate for focal epilepsy with secondary bilateral synchronization on EEG in case of onset of epilepsy in adolescence than for epilepsy with onset in adult age. Moreover focal epilepsy with secondary bilateral synchronization on EEG in case of onset in adolescence can form phonotypical copies of idiopathic generalized forms of epilepsy.
