摘　　要：目的 分析脑梗死后抑郁症脑电图(EEG)特点。方法 选择本院2019年10月~2022年6月脑梗死患者100例作为研究对象,根据是否存在抑郁分为抑郁组53例,无抑郁组47例。另选择同期的45例体检健康者作为对照组。三组均进行EEG检查。比较三组的脑电图差异波型,α、β、δ、θ波的分布。结果 抑郁组的异常脑电图率显著高于无抑郁组、对照组,差异均有统计学意义(P<0.05)。抑郁组的低振幅α波、低振幅δ波均高于无抑郁组和对照组,差异均有统计学意义(P<0.05);三组的低振幅β波、低振幅θ波、α波不对称、α波泛化/前移、β波活动增加比较,差异均无统计学意义(P>0.05)。结论 脑梗死后抑郁症EEG多呈异常表现,并以低振幅α波、低振幅δ波为主。Objectivee To analyze the characteristics of electroencephalogram(EEG)in depression after cerebral infarction.Methods A total of 100 patients with cerebral infarction in our hospital from October 2019 to June 2022 were selected as study subjects.According to whether there is depression,53 cases were divided into depression group and 47 cases were divided into non depression group.Another 45 healthy people in the same period were selected as the control group.EEG examination was performed in all three groups.The EEG difference wave patterns of the three groups,andα、βS、Wave distribution were compared.Results The rate of abnormal EEG in depression group was significantly higher than that in non-depression group and control group(P<0.05).Low amplitude of depression groupαWave,low amplitude S Wave was significantly higher than that in the non-depression group and the control group(P<0.05).Low amplitude of three groupsβWave,low amplitude Wave,αWave asymmetry,αWave generalization/forward,shiftβwere no significant difference in the increase of wave activity(P>0.05).Conclusion The EEG of depression after cerebral infarction showed abnormal performance with low amplitudeαWave,low amplitude Waves predominate.
