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.
This study was a randomized sham-controlled trial to evaluate the efficacy and safety of dTMS in treatment-resistant BD patients.
Fifty patients received 20 sessions of active or sham dTMS over theleft dorsolateral prefrontal cortex (H1-coil, 55 18 Hz 2 s 120% MT trains). The primary outcome was changes in the 17-item HamiltonDepression Rating Scale (HDRS-17) from baseline to endpoint (week 4). Secondary outcomes were changes from baseline to the end ofthe follow-up phase (week 8), and response and remission rates. Safety was assessed using a dTMS adverse effects questionnaireand theYoung 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 dTMSwas 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.
