- Treatment of Bipolar Depression with Deep TMS: Results from a Double-Blind, Randomized, Parallel Group, Sham-Controlled Clinical Trial(2017) TAVARES, Diego F.; MYCZKOWSKI, Martin L.; ALBERTO, Rodrigo L.; VALIENGO, Leandro; RIOS, Rosa M.; GORDON, Pedro; SAMPAIO-JUNIOR, Bernardo de; KLEIN, Izio; MANSUR, Carlos G.; MARCOLIN, Marco Antonio; LAFER, Beny; MORENO, Ricardo A.; GATTAZ, Wagner; DASKALAKIS, Zafiris J.; BRUNONI, Andre R.Bipolar depression (BD) is a highly prevalent condition with limited therapeutic options. Deep (H1-coil) transcranial magnetic stimulation (dTMS) is a novel TMS modality with established efficacy for unipolar depression. We conducted a randomized sham-controlled trial to evaluate the efficacy and safety of dTMS in treatment-resistant BD patients. Patients received 20 sessions of active or sham dTMS over the left dorsolateral prefrontal cortex (H1-coil, 55 18 Hz 2 s 120% MT trains). The primary outcome was changes in the 17-item Hamilton Depression Rating Scale (HDRS-17) from baseline to endpoint (week 4). Secondary outcomes were changes from baseline to the end of the follow-up phase (week 8), and response and remission rates. Safety was assessed using a dTMS adverse effects questionnaire and the Young Mania Rating Scale to assess treatment-emergent mania switch (TEMS). Out of 50 patients, 43 finished the trial. There were 2 and 5 dropouts in the sham and active groups, respectively. Active dTMS was superior to sham at end point (difference favoring dTMS = 4.88; 95% CI 0.43 to 9.32, p = 0.03) but not at follow-up. There was also a trend for greater response rates in the active (48%) vs sham (24%) groups (OR = 2.92; 95% CI = 0.87 to 9.78, p = 0.08). Remission rates were not statistically different. No TEMS episodes were observed. Deep TMS is a potentially effective and well-tolerated add-on therapy in resistant bipolar depressed patients receiving adequate pharmacotherapy.
