Summary

This trial will use transcranial magnetic stimulation (TMS) to study how hallucinations work in schizophrenia and whether or not the magnetic field can improve symptoms.

Who is the study for?
This trial is for individuals with schizophrenia or schizoaffective disorder. It's not suitable for those who've had substance use disorders recently, have ambidexterity, contraindications to TMS or MRI like neurological issues, head trauma with unconsciousness, seizures/epilepsy (or family history of it), metal in the brain/skull, implanted medical devices, or claustrophobia in MRI.
What is being tested?
The study tests transcranial magnetic stimulation (TMS) as a noninvasive brain stimulation technique to understand and potentially improve hallucinations in schizophrenia. Participants will receive repetitive TMS (rTMS) or a sham version that mimics the procedure without actual stimulation.
What are the potential side effects?
Possible side effects of rTMS include discomfort at the coil placement site on the scalp, headache, lightheadedness, and rare risk of seizure. The sham treatment may cause similar sensations due to placebo effect but does not involve active brain stimulation.
