Study Description
Brief Summary:
Transcranial magnetic stimulation (TMS) involves the use of magnetic fields to non-invasively stimulate the brain. Studies overseas have suggested this may be an effective and safe treatment for auditory hallucinations in patients with schizophrenia. This is a sham-controlled, double-blind trial of TMS stimulation for the treatment of auditory hallucinations in patients with schizophrenia.
