Can a faster brain stimulation schedule beat the standard for depression?

This clinical trial is testing whether a faster, more intensive schedule of a brain stimulation treatment called intermittent theta burst stimulation (iTBS) works better than the standard schedule for adults with major depressive disorder. Participants will be randomly assigned to receive either accelerated iTBS (45 sessions over about 15 days) or standard iTBS (20 sessions over 4 weeks), in addition to their usual antidepressant medication. The main goal is to compare changes in depressive symptoms, measured by a standard rating scale, from the start to the end of treatment. The study will also look at other outcomes like cognitive function, quality of life, sleep, and safety.
