Application of Video EEG in Early Diagnosis and Prognosis Evaluation of Epilepsy Secondary to Cerebral Infarction
Objective To analyze the efficacy of video EEG in the early diagnosis of epilepsy secondary to cerebral in-farction and its prognostic value.Methods 110 patients with epilepsy secondary to cerebral infarction were studied,and they were followed up for one year.Routine electroencephalogram and video electroencephalogram were performed.The detection rate of abnormal electroencephalogram was compared between the two methods,and the detection rate of epileptic focus in differ-ent infarcts was counted;Then the patients were divided into groups according to whether they had relapse or not,and the initial video EEG signals and medication were observed in the two groups.Results The detection rate of abnormal EEG in video EEG was higher than that in routine EEG,and the detection rate of abnormal EEG in epilepsy without cerebral cortex infarction was higher than that in routine EEG;The detection rate of diffuse slow waves in video EEG in the epilepsy recur-rence group was lower than that in the non recurrence group,and the detection rate of abnormal epileptiform discharge waveform was higher than that in the non recurrence group,with statistical significance(P<0.05).Conclusion It is feasible to use video EEG to diagnose epilepsy secondary to cerebral infarction,especially to effectively detect the epilepsy focus formed after deep cerebral infarction,and to evaluate the prognosis of the disease according to epileptic discharges.
