摘要
为比较Alzheimer病(AD)和老年精神分裂症(SS)患者脑电图(EEG)的各自特点。方法对32例AD患者、24例SS患者及39例正常老人,使用丹麦SEEG—16道脑电图仪,完成EEG检查。结果AD患者EEG异常率87.5%,显著高于SS患者的66.7%和正常老人的28.2%。(X检验,P<0.01)。AD患者、SS患者分别较正常老人慢波活动及α慢波化显著增加(X检验,P<0.01)。AD患者和正常老人2个年龄组的异常率随年龄增大而增高。AD患者和正常老人EEG检查结果与CASI量表分之间存有一定关系,但在SS患者中则否。结论AD患者和SS患者的EEG表现出具有不同于正常衰老的变异,且AD和SS在<8.5Hzα波上有明显差异,因而EEG对了解AD患者和SS患者及两个疾病鉴别上仍有一定参考价值。
Objective To investigate the variations of electroencephalogram(EEG) of aged patients with Alzheimer's disease(AD)and chronic schizophrenia.Methods The BEAM-EEG was recorded from the scalps of 32 patients diagnosed as AD according to DSM-Ⅲ-R,24 patients diagnosed as chronic schizophrenia according to CCMD-Ⅱ-R and 39 normally aged controls,using a Dantec Concerto SEEG-16 Instrument.Results Compared with that of normal controls(28.2%) and of schizophrenics(66.7%),the abnormal ratio of EEG was significantly higher in AD patients(87.5%,P<0.05).The varied EEG was presented as slower α wave(<8.5Hz),increased θ and δ waves.Both AD patients and normal controls showed their EEG further abnormal as their age increased.The relationship between EEG and one cognitive assessment-CASI score was also found within the AD group,but in was not found within schizophrenia group.Conclusions The variations of EEG between AD patients and aged schizophrenics were confirmed in the present study,and their clinical significances were suggested.
