Despite adequate pharmacological therapy, up to 30% of schizophrenia patients suffer from treatment-refractory auditory hallucinations (TRAH). Studies defining the role of transcranial direct current stimulation (tDCS) in the management of auditory hallucinations have shown mixed results.
To address the controversial efficacy of this treatment strategy, recently a meta-analysis was published in Asian Journal of Psychiatry by Jiang et al. The authors have shown that adjunctive tDCS is not more efficacious than sham tDCS in improving auditory hallucinations symptoms. But subgroup analysis suggested that twice-daily stimulation or ≥ 10 stimulation sessions may be beneficial in this regard.
