Abstract:Objective To investigate the clinical effects of electroencephalographic (EEG) biofeedback combined with lamotrigine in the treatment of chronic schizophrenia with tardive dyskinesia (TD).Methods The 82 cases of chronic schizophrenia with TD in Hangzhou Seventh People's Hospital from June 2018 to June 2020 were randomly divided into control group (41 cases) and observation group (41 cases). Both of the groups maintained the original antipsychotic drug regimens. The control group was treated with lamotrigine, and the observation group was treated with EEG biofeedback on the basis of the control group. The treatment course of the two groups was 8 weeks. The Abnormal Involuntary Movement Scale (AIMS) score, β-band EEG power value, Brief Psychiatric Rating Scale (BPRS) score and Positive and Negative Syndrome Scale (PANSS) score were compared between the two groups before and after 8 weeks of treatment.Results The overall effective rate in the observation group was higher than that in the control group (P < 0.05). The differences of AIMS, BPRS and PANSS scores before and after treatment in the observation group were higher than those in the control group (P < 0.05). Besides, the differences of EEG power values at C3, C4, P3 and P4 before and after treatment in the observation group were higher than those in the control group (P < 0.05).Conclusions EEG biofeedback combined with lamotrigine is effective in the treatment of chronic schizophrenia with TD and can alleviate the severity of TD.
