Adjunctive High-Definition Transcranial Direct Current Stimulation in Treatment of Resistant Auditory Verbal Hallucinations in Schizophrenia: A Randomized Sham-Controlled Trial.

Background: Resistant auditory verbal hallucination (AVH) remains a disabling symptom in schizophrenia. Transcranial direct current stimulation (tDCS) and its more targeted variant, high-definition tDCS (HD-tDCS), have shown promising results in reducing AVH. We aimed to determine the effects of adjunctive HD-tDCS on various dimensions of AVH in patients with schizophrenia.
