Core Tip

Core Tip: This work rigorously follows the PRISMA guidelines and includes nine studies with a total of 425 participants, highlighting a significant reduction in auditory hallucination scores post-transcranial direct current stimulation treatment. Given the pressing need for effective adjunctive treatments for schizophrenia, especially for symptoms as challenging as auditory hallucinations, our findings offer valuable insights into innovative therapeutic strategies.
