Summary

This trial is examining how well a new treatment - navigated repetitive transcranial magnetic stimulation (nrTMS) - works in people with schizophrenia. They are testing to see if this treatment can improve symptoms and cognitive function.

Who is the study for?
This trial is for English-speaking individuals with schizophrenia who are clinically stable on a low to moderate dose of antipsychotic medication, without neurological disorders or substance use issues. They must be in good physical health and able to undergo MRI scans. Pregnant individuals, those with implanted metal/electronic devices, scalp wounds/infections, ongoing seizures, or severe claustrophobia cannot participate.
What is being tested?
The study tests whether high-frequency transcranial magnetic stimulation (TMS) targeting the medial prefrontal cortex can improve self-agency judgments in people with schizophrenia. It will also assess cognitive improvements and daily functioning as well as potential changes within the brain's self-agency network.
What are the potential side effects?
Potential side effects of TMS may include discomfort at the stimulation site, headache, lightheadedness, or seizures in very rare cases. Most people tolerate TMS well and serious side effects are uncommon.
