TD, schizophrenia, psychiatric
The important result of this study is that tDCS could not improve cognitive function in patients with long-term hospitalized chronic schizophrenia with TD. Conversely, in an earlier randomized controlled study [In this study, we used PANSS and SANS to assess the psychiatric symptoms of patients. Based on the result, we found that the psychiatric symptom scores of the two groups all improved after tDCS. However, there was no significant difference in psychiatric symptom scores after treatment between the two groups of patients. However, in a 2020 randomized clinical trial [At present, the mechanism of tDCS in the treatment of cognitive function in patients with schizophrenia is not entirely clear. Current research suggests that mechanisms posited to underlie its effects include modification of cortical excitability and neural plasticity [Previous studies [
