摘要: 目的 探讨亚健康失眠人群的脑功能状态变化及其与失眠程度之间的关系。方法 应用脑电超慢涨落图(EFG)分析仪与匹兹堡睡眠质量指数(PSQI)量表,检测亚健康失眠人群的脑功能状态指数,包括运动指数、兴奋抑制指数、血管舒缩指数与PSQI总分。结果 46例失眠者(其中男27例,女19例)脑功能均有异常,其中脑功能状态指数中的运动指数、兴奋抑制指数的实测值都高于正常参考值,差异均有统计学意义(P<0.01)。全部受检者PSQI总分均≥7分,其中以12～16分的中度失眠为主,占受检总人数的50.0%。所有失眠者PSQI总分与脑功能状态3种指数实测值之间均无线性相关性。结论 亚健康失眠人群脑功能状态存在不同程度的异常,但脑功能状态异常与其失眠程度之间无明显密切关系。Abstract: Objective To investigate the change of cerebral function in sub-healthy people with insomnia and the relationship between the index of cerebral function(ICF)and the degree of insomnia.Methods Detecting the ICF and Pittsburg sleep quality index(PSQI)values of 46 insomniacs by encephalofluctuograph(EFG)technique and PSQI scale respectively.Results The cerebral function of 46 insomniacs(male 27,female 19)were all abnormal.The exercise index and the excitement-inhibition index were decreased obviously(P<0.05).PSQI value of each insomniacs exceeded 7,and the value of most objects was between 12 and 16(50.0%).The ICF were not significantly correlated with the value of PSQI(P>0.05).Conclusion The cerebral function in sub-healthy people with insomnia is abnormal obviously,but the abnormal state is not inevitable relative to the degree of insomnia.
