Efficacy of transcranial direct current stimulation (tDCS) as a treatment for persistent hallucinations in patients with schizophrenia: A systematic review and meta-analysis

Hallucinations are common symptoms of schizophrenia, yet 25% to 30% of patients would still continue to experience persistent hallucinations even after continuous pharmacological treatment (Shergill et al., 1998). Studies have thus investigated on the use of transcranial direct current stimulation (tDCS) in reducing the severity of hallucination in patients with psychosis. TDCS is a non-invasive brain stimulation technique. It acts by depolarizing (anodal stimulation) or hyperpolarizing (cathodal stimulation) the neuronal membrane potential by applying a very low-intensity electrical current on scalp.
