Abstract:Objective To investigate the effect of electroencephalogram (EEG) biofeedback therapy combined with cognitive function training on the cognitive function of the patients with schizophrenia. Methods From January 2016 to June 2017, 92 schizophrenic patients were randomly divided into an observation group and a control group with 46 cases in each group. Cognitive function training was given to both groups, while EEG biofeedback therapy was given to the observation group on the basis. The cognitive function of the two groups of patients before and after treatment was compared. Results There was no significant difference in β wave, θ wave or SMR wave before treatment between the two groups (P > 0.05). However, β wave and SMR wave increased (P < 0.05), while θ wave decreased after treatment in the observation group when compared with the control group (P < 0.05). There was no statistical difference between the two groups before treatment in the score of the constant step auditory continuous addition test (P > 0.05). After treatment, the score of the constant step auditory continuous addition test was higher in the observation group when compared with the control group (P < 0.05). There was no significant difference in the number of continuous errors or the completed classification number between the two groups before treatment (P > 0.05). After treatment, the number of continuous errors decreased (P < 0.05), and the completed classification number increased (P < 0.05) in the observation group. There was no significant difference in IL-6 or TNF-α between the two groups before treatment (P > 0.05). After treatment, the levels of IL-6 and TNF-α in the observation group were lower than those in the control group (P < 0.05). Conclusions EEG biofeedback therapy combined with cognitive function training can improve the cognitive function in the patients with schizophrenia.
