高龄癫的低电压脑电图与CT的对比分析

THE COMPARATIVE ANALYSIS ON LOW-VOLTAGE EEG WITH CT IN SENILE PATIENT WITH EPILEPSY

目的:探讨低电压脑电图与老年人癫发病的相关性。方法:对22例62～79岁的老年晚发癫患者的脑电图与CT进行对比分析,并将18～55岁,脑电图为低电压的人群做为对照组进行分析。结果:入选组,22例患者的低电压脑波,14例CT显示阳性,其中,9例为脑梗塞,4例为脑动脉硬化伴脑萎缩,1例为脑软化灶。而对照组中44例,仅有1例CT显示脑梗塞,1例钙化点,两组比较X2=27.9134,P<0.01。结论:在老年人中,癫发作患者表现为低电压脑波时,应警惕脑器质性病变的存在,要及时做CT检查。

Objective：To explore the pathogenesis on low-voltage EEG of senile patient with epilepsy.Methods：EEG and CT on 22 cases of 62～79 years-old senile patients with late-onset epilepsy were compared,and 18～55 years-old crowd with low-voltage EEG as the control group was analyzed.Results：In selected group,CT of 22 patients with low-voltage EEG showed that 14 cases were positive,9 cases were cerebral infarction,4 cases were cerebral arteriosclerosis with cerebral atrophy and 1 case was cerebral malacia.In the control group of 44 cases,CT of only 1 case showed that cerebral infarction,1 case was calcification point.The x2 of two groups = 27.9134,P 0.01.Conclusion：In senile patients with epileptic seizures,low-voltage EEG shows probable presence of cerebral organic disease,CT should be examined in time.
