Effectiveness of Transcranial Direct Current Stimulation (TDCS) on on reducing the symptoms in chronic schizophrenia disorder

The purpose of this study was to evaluate the effect of Trancranial Direct Current Stimulation (TDCS) on reducing positive and negative symptoms in chronic schizophrenia.

The method of this study was quasi-experimental with ABA design. The statistical population was all people with chronic schizophrenia who were admitted to the Fouman Patient Psychiatric Treatment Center. Purposeful and accessible sampling method was used among which 4 people were selected randomly. To collect statistical data research of Positive and Negative Symptoms inventory and transcranial Direct Current Stimulation Instrument (TDCS) has been used.

The results showed that anodic tDCS application on the left dorsolateral prefrontal cortex (DLPFC) had a positive effect on decreasing positive, negative, and depression symptoms in people with schizophrenia disorder.

In general, it can be said that was effective transcranial Direct Current Stimulation (TDCS) in reducing the symptoms of schizophrenia, so this method can be used in the treatment of people with chronic schizophrenia disorder.
