摘要
目的探讨脑梗死后癫痫患者定量脑电图(QEEG)的特点。方法将67例脑梗死后初次癫痫患者作为观察组,选择同期健康体检者74例作为对照组,入选者采用上海诺诚电气有限公司生产的型号为Z2N-F-32W脑电图仪进行QEEG功率谱分析,δ(0.8~3.9Hz)、θ(4.0~7.7Hz)、α(7.8~12.9Hz)和β(13.0~20.0Hz),计算出各个频带的绝对功率值及(δ+θ)/(α+β)值,并作为观察评估指标进行比较。结果观察组脑梗死病灶大小与(δ+θ)/(α+β)值无相关性(P>0.05);观察组左额区(3.15±2.63 vs 1.97±1.42,P=0.002)、右额区(3.17±2.53 vs 1.88±1.46,P=0.000)、左中央(2.69±2.59 vs 1.65±1.28,P=0.004)、左顶区(2.58±2.45 vs 1.28±1.10,P=0.000)、右顶区(2.69±2.81 vs 1.21±1.06,P=0.000)、左枕区(P=0.000)、右枕区(P=0.000)、左颞区(P=0.000)以及右颞区(P=0.002)的(δ+θ)/(α+β)值显著高于对照组,而在右中央的(δ+θ)/(α+β)值与对照组比较无统计学差异(P>0.05)。脑梗死后早发性癫痫患者与迟发性癫痫患者的(δ+θ)/(α+β)值无统计学差异(P>0.05)。结论QEEG对脑梗死后癫痫的诊断、脑梗死后患者异常脑电活动评价有重要价值。
Objective To study the characteristics of quantitative EEG in epilepsy patients after ischemic stroke. Methods Sixty-seven first-ever epilepsy patients after ischemic stroke served as an observation group and 74 age-matched healthy persons served as a control group in this study. The quantitative EEG power spectra of two groups,including δ （0.8--3.9 Hz） ,θ（4.0--7.7 Hz）, α （7.8--12.9 Hz） and β （13.0--20.0 Hz）,were analyzed using the Z2N-F32w EEG device made in Shanghai. The （δ＋θ）/（α-β） power value on different regions of brain between the two groups was computerized and used as an observation index. Results The isehemie stroke size was not re- lated with the （δ＋θ）/（α-β） power value in observation group （P〉0.05）. The （δ＋θ）/（α-β） power value on the left frontal area （3. 15±2.63 vs 1.97±1.42,P=0. 002）,right frontal area （3.17±2.53 vs 1. 88±1. 46,P=0. 000）,left central area （2. 69＋2. 59 vs 1. 65±1. 28,P= 0. 004） ,left parietal area （2.58±2.45 vs 1.28±1.10,P=0. 000） ,right parietal area （2.69＋_2.81 vs 1.21±1.06, P=0. 000）, left occipital area, right occipital area, left temporal area and right tempo- ral area was significantly higher in observation group than in control group （P〈0.01）. No signifi- cant difference was found in （δ＋θ）/（α-β） power value on the right central lobe and left occipital lobe between the two groups and between early and late onset epilepsy patients after ischemic stroke （P〉0.05）. Conclusion Quantitative EEG plays an important role both in diagnosis of epi- lepsy and in assessment of abnormal brain electrical activity in epilepsy patients after ischemic stroke.
