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。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.
