目的 探讨额叶癫痫发作临床表现及脑电改变特征。方法 利用 ZN80 0 0型同步录像脑电图(EEG)对 10例额叶癫痫患者进行脑电和行为监测。结果 监测时间内共监测到 89次临床发作 ,睡眠 6 2次 ,清醒 2 7次 ,持续时间 10～ 90秒。临床表现 :单纯部分性发作 3例 12次 ,复杂部分性发作 6例 70次 ,强直 -阵挛性发作 1例 7次 ;发作期 EEG:额区或额区为主的癫痫样放电 (棘波、尖波、棘慢、尖慢综合波 ) 8例 71次 ,高 -极高幅慢波 (θ,δ) 2例 18次 ,痫样放电出现率 10 0 % ;发作间期 EEG:睡眠 EEG示额区阵发性痫样放电 5例 ,阵发性高幅慢波 (θ,δ) 4例 ,未见特殊 1例 ;清醒 EEG示额区高幅慢波 3例 ,痫样放电 2例 ,背景正常而过度换气诱发痫样放电 2例。结论 额叶癫痫临床发作以运动症状为主 ,常于夜间发作 ,发作频繁而短暂。发作期EEG为额区痫样放电亦可为高幅慢波 ,与临床发作同步。
Objective To investigate the clinical manifestations and the changes of EEG in frontal lobe epilepsy. Methods 10 cases of frontal lobe epilepsy were monitored by EEG of ZN80 0 type. Results A total of 89 clinical seizures were monitored during the monitoring period, 62 times of sleep, 27 times of awake, and the duration of 10 ~ 90 seconds. Clinical manifestations: simple partial seizures in 3 cases 12 times, complex partial seizures in 6 cases 70 times, tonic - clonic seizures in 1 case 7 times; seizure EEG: frontal or forehead epileptiform discharges (spikes , Echocardiography, echocardiography, echocardiography, echocardiography, echocardiography, echocardiography, echocardiography, There were 5 cases of paroxysmal epileptiform discharge in frontal area, 4 cases of paroxysmal high amplitude slow wave (θ, δ), and no special case in 1 case. There were 3 cases of high amplitude slow wave in awake EEG area, 2 cases of epileptiform discharge , Normal background and hyperventilation induced epileptiform discharges in 2 cases. Conclusions The clinical onset of frontal lobe epilepsy is characterized by motor symptoms, and often occurs at night. The seizures are frequent and transient. Seizure EEG epileptiform discharge for the frontal region may also be high amplitude slow wave, and clinical seizures simultaneously.
