2、时脑电图(EEG)各个成分波(8,0,a,B波)的幅度值和治疗后I周内的EEG,以及治疗前脑电活动,刺激电量,发作后抑制指数等相关因素.结果:MELT后的EEG异常发生率比治疗前高(P<0.01);Spearman相关分析显示MECr时8,0,d和p波的幅度值与抑制指数呈显着正相关(占:P<O.05,0,a,p:P<0.01),除p波外均与刺激电量呈显着负相关(艿:P<0.05,0,a:P<0.01,盆:P>0.05),而各个波的幅度值与年龄及治疗前,后脑电活
3、动等因素的相关性分析元统计学意义.结论:MEcr对精神障碍者脑电活动有一定的影响;治疗发作时8,0,a和B波的幅度值与发作后抑制指数及刺激电量关系密切.[关键词]元抽搐电休克治疗;脑电活动;脑电图[中图分类号]R749.054;R454.1[文献标识码]A[文章编号]1007.4716(2010)03.0158.04EffectsofModifiedElectricConvulsiveTherapyonBrainElectricalActivityinthePatientswithMentalD
