rTMS and MEG for auditory hallucinations via self controlled clinical trials. Repetitive transcranial magnetic stimulation (rTMS) can increase or decrease cortical excitability in patients with psychosis (such as schizophrenia). Here, we conducted an open clinical trial on 60 schizophrenics with auditory hallucinations. We searched for targets through magnetoencephalography and then intervened to prove that rTMS guided by magnetoencephalography is effective for auditory hallucinations.
Before intervention, each patient was scheduled to collect three magnetoencephalogram data sessions. Apply MEG technology to calculate possible locations and determine three intervention targets. Pseudo stimulation in the first week, 5-day intervention, 3 targets per day, each target for 23 minutes, with a 30 minute interval between each target. Evaluate the scale after the first week of pseudo stimulation. Week 2-4 real stimulation, intervention 5 days a week, 3 targets per day, each target for 23 minutes, with a 30 minute interval between each target. After the end of the fourth week, evaluate the scale. And follow-up evaluations will be conducted on the 7th, 14th, 30th, 60th, and 90th days after the intervention.
