Establishing a Dose-response Relationship With Accelerated Transcranial Magnetic Stimulation
This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In a double-blind, randomized, sham-controlled fashion, half the participants will receive accelerated theta-burst stimulation while half will receive sham treatment.
Stanford is currently accepting patients for this trial.
