目的 :探讨Video -EEG监测癫发作早期脑电变化的临床应用价值。方法 :对 96例临床确诊的癫患者进行发作早期Video -EEG监测并分析其结果。结果 :共监测到 3 2例癫发作(3 3 % ) ,其中全身性癫 4例 ;颞叶癫 16例 ,颞外癫 12例。发作早期脑电异常主要分快活动、慢活动及快慢混合活动三大类。根据发作早期脑电变化 ,2 3例 (72 % )作出定位诊断。结论 :癫发作早期脑电图脑电变化对致灶的定位 (定侧 )诊断有重要价值
Objective: To investigate the clinical value of Video-EEG in detecting early EEG changes in epileptic seizures. Methods: Ninety-six patients with clinically diagnosed epilepsy underwent early Video-EEG monitoring and the results were analyzed. Results: A total of 32 epileptic seizures (33%) were detected, including 4 cases of generalized epilepsy, 16 cases of temporal lobe epilepsy and 12 cases of temporal epilepsy. Early episodes of EEG mainly sub-fast activities, slow activities and rapid mixed activities of the three categories. According to the early episodes of EEG changes, 23 (72%) were diagnosed locally. Conclusion: The changes of EEG in the early stage of epileptic seizure are of great value in the diagnosis of foci
