Clinical Application Value of Video-EEG Monitoring in Epilepsy

Objective To explore the clinical application value of Video-EEG monitoring in epilepsy.Methods Video-EEG monitoring under state of awaking and sleeping were performed continuously in 975 patients with paroxysmal events.We analysed the relation between seizures and abnormal discharge,the phase when abnormal discharge appeared,and relation between classification of epilepsy and abnormal discharge.We also observed EEG changes before seizures and different EEG findings in both ictal and interictal period.Results The characteristic events were captured in 568 of the 975 patients and out of the 568 patients,443 had clinical events accompanying epileptiform discharge.Seizure types were defined in 403 of 443 patients with epilepsy seizure,and 125 seizure types were amended.The antiepileptic drugs were changed in 55 cases.With drawled in 16 cases,76 refractory epilepsy patients whose EEG were abnormal change before seizure were performed operations.Conclusion VEEG can record much more epileptiform discharge.It is an effective method in both diagnosis and classification of epilepsy.To guide medical therapy and preoperative localization of epilepeogenic zone.
