Analysis of cerebral function in sub-healthy people with insomnia

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.
