【摘要】 目的:比较分析亚健康人群中失眠患者与正常人群的脑电地形图,获得诊断学上的证据。方法:对500例亚健康人群中失眠患者(亚健康组)及500例健康人群(健康组)均进行脑电地形图及头颅CT检测,并把二者进行对比研究。结果:脑电地形图中亚健康组中失眠者α波波幅降低463例,调节调幅欠佳474例。β活动增多473例。过度换气(HV)后θ活动增多456例。δ活动增多27例。无明显变化17例。α频带平均功率谱降低且不对称,在Scale(标尺)为32时其平均功率谱值<1.5uV,颜色灰阶为<3灰阶为479例,θ频带平均功率谱在大脑前部有增高者276例。平均功率谱值在<1.5 uV。β频带平均功率谱增高为479例。健康组中α波波幅降低26例,调节调幅欠佳23例。β活动增多37例。过度换气(HV)后θ活动增多33例。δ活动增多2例。无明显变化465例。α频带平均功率谱正常并且对称,在Scale(标尺)为32时其平均功率谱值在>3.5uV,颜色灰阶为>5灰阶为465例。与健康组比较,亚健康组出现的异常率明显增高(P<0.05);头颅CT检测2组均显示正常范围。结论:亚健康失眠患者的脑电活动不稳定,具有明显焦虑趋势,脑电地形图侧重于大脑功能性诊断,对亚健康人群中失眠患者有诊断价值。更多还原

【Abstract】 Objective: To analyze brain electrical activity mapping between patients with insomnia in subhealth population and normal population.Methods: Five hundreds cases of insomnia in subhealth population(subhealth group) and 500 normal controls(control group) were subjected to examinations of brain electrical activity mappings,electroencephalograms and CT.Results: Frequency of δ,θ,α,and β in brain electrical activity mappings of control group was significantly higher then in subhealth group(P<0.05).CT examination revealed normal findings in both two groups.Conclusion: The brain electrical activity of patients with insomnia in subhealth population is unstable.Psychological intervention can improve the recovery of patients with insomnia,and the quality of daily life.更多还原
