Progress on distinguishing in epileptic and non⁃epileptic seizure

Abstract

Epileptic seizure is a paroxysmal brain dysfunction caused by the abnormal discharge of excessive synchronization of brain neurons, accompanied by epileptiform discharge of EEG. Non⁃epileptic seizure (NES) is a group of diseases caused by various reasons. Although they are not accompanied by epileptiform discharges of EEG, they have similar clinical manifestations to seizures, rendering the differentiation from seizures difficult. Video electroencephalography (VEEG) technology, which has been widely used in the diagnosis and treatment of nervous system diseases, is key to the differential diagnosis of epileptic seizures. This article reviews the role of symptomatic and EEG features in the differential diagnosis of epileptic seizure and NES, as well as common NES that can be differentiated from epileptic seizure, so as to provide theoretical basis for accurate diagnosis and treatment of epilepsy.
