Auditory hallucinations are the most common psychiatric symptoms of schizophrenia with high recurrence and refractoriness. Transcranial direct current stimulation (tDCS), a novel, non-invasion and affordable brain stimulation technique, has been recently applying on the schizophrenia patients to treat the auditory hallucinations. To analyze the efficacy of tDCS treatment on such symptoms and to reveal its potential working mechanisms, we carried out a structured literature search in PubMed, Embase and Cochrane Library database up to May 12, 2018. Five studies that met inclusion criteria with a total of 137 patients were included in this meta-analysis. After pooling all the data, we found that there was no significant effect between active group and sham group of tDCS (p = 0.18). When we removed one study that did not collaboratively stimulate the frontal-temporal sites, the active tDCS group marks a significant improvement of therapeutic effect compared with sham group (p = 0.007). Our findings suggested that tDCS could be a promising tool to alleviate auditory hallucinations, provided that the simulation sites and protocols are targeting at the sensorimotor frontal-parietal network.
