[Abstract] Objective To explore the effects of EEG biofeedback intervention on cognitive function and life ability in schizophrenia. Methods A total of 105 patients with schizophrenia included from February 2023 to May 2025. They were randomly divided into two groups using the numerical table method. The control group received drug treatment, while the observation group received combined EEG biofeedback intervention, both for 8 weeks of treatment. The positive and negative symptom assessment scales, mini mental state examination (MMSE), and activity of daily living scale (ADL) before and after treatment were compared. Results After treatment, the scores of various mental symptoms in both groups were lower than before treatment, but the negative symptom scores in the observation group were significantly lower than those in the control group after treatment (P<0.05). There was no significant difference in the scores of the other two items (P>0.05). After treatment, the MMSE scores and ADL scores in both groups were higher than before treatment, but the observation group had significantly higher scores in both categories compared to the control group (P<0.05). Conclusion EEG biofeedback intervention can alleviate negative symptoms in patients with schizophrenia, improve cognitive function and daily living abilities.
