AEEG monitoring in 257 patients with clinical diagnosed epilepsy or proxysmal disease

Objective: To explore the value of AEEG monitoring in the diagnosis and differential diagnosis of epilepsy. Methods: AEEG was carried out in 257 patients (devided into clinical diagnosed epilepsy group and doubtful epilepsy group)with no epileptiform discharges in routine EEG and the findings were analyzed.Results: The positive rate of epileptiform discharges in patients with epilepsy was 59.4%,and it was 19.9% in the doubtful epilepsy group. The epileptiform discharges were mainly found during NREM phase. No significant difference of the positive rate of epileptiform discharges was found in all kinds of seizure type. Conclusion: AEEG might increase the detection rate of epileptiform discharges.It might be of important significance in the diagnosis of epilepsy.
