Can a gentle brain current silence voices that medication Can't?

This trial tests whether transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, can reduce auditory hallucinations in people with schizophrenia who haven't found relief from antipsychotic medications. Participants receive either real tDCS or a placebo (sham) stimulation, with two sessions per day for two weeks. The study measures changes in hallucination severity and overall symptoms to see if this approach could be a helpful addition to current treatments.
