Comparison of the effect of different electroencephalogram in the diagnosis of temporal lobe epilepsy / 中国基层医药

ABSTRACT

Objective To compare the clinical value of different electroencephalogram (EEG) in the diagnosis of temporal lobe epilepsy.Methods A total of 123 patients in Taizhou Central Hospital received routine EEG , dynamic EEG,routine sphenoidal electrode examination ,and long sphenoidal electrode examination.The the detection rate of epileptic waves in EEG , awake and sleep phases of patients with temporal lobe epilepsy were compared . Results The detection rate of epileptiform wave by the routine EEG was 52.63%,which by the dynamic EEG was 61.11%,and there was no statistically significant difference (P＞0.05).The detection rate of epileptiform wave by the long range sphenoidal electrode EEG was 63.64%,which was higher than that by the conventional sphenoidal electrode EEG(22.22%)(χ2＝8.776,P＜0.05).The detection rate of epileptiform wave in the sleep period EEG in temporal lobe epilepsy was 51.35%,which was higher than that in the awake period (29.73%),and the difference was statistically significant ( χ2＝5.739, P ＜0.05).Conclusion Different types of EEG have their respective advantages in diagnosis of temporal lobe epilepsy ,sphenoidal electrodes and sleep induced temporal lobe epilepsy can significantly improve the detection rate of abnormal EEG ,has important clinical value in the diagnosis of temporal lobe epilepsy.
