About this trial
In this study, the investigators will examine whether a type of repetitive transcranial magnetic stimulation called accelerated intermittent theta burst stimulation (iTBS) can augment neurocognition in individuals who receive treatment with clozapine. Following a baseline evaluation and magnetic resonance imaging (MRI), participants will undergo a session of iTBS +MRI and session of sham delivery + MRI. The order for these sessions will be blinded and randomized. The investigators predict that accelerated iTBS will enhance neurocognition relative to sham delivery.
