Efficacy and Safety of Deep Transcranial Magnetic Stimulation in Office Workers with Treatment-Resistant Depression: A Randomized, Double-Blind, Sham-Controlled Trial
Abstract
Objectives: Major depression is a highly prevalent disorder that causes economic burden in office workers. We conducted a randomized, double-blind, sham-controlled trial to evaluate the efficacy and safety of deep transcranial magnetic stimulation (dTMS) in office workers with treatment-resistant depression.
Methods: In this study, we randomized office workers taking administrative leave for treatment-resistant major depressive disorder or bipolar disorder with current major depressive episode. dTMS treatment was applied at 120% resting motor threshold with 18 Hz over the left dorsolateral prefrontal cortex. The treatment sessions delivered a total of 1,980 pulses a day, 5 days a week, for 4-6 weeks. The primary outcome was change in the total score on the 21-item Hamilton Depression Rating Scale (HDRS-21) from baseline to the end of study in an intent-to-treat analysis. The secondary outcomes were the response and remission rates. We also assessed changes in cognitive function and adverse events.
Results: Forty patients were randomized to active or sham dTMS groups (1:1). The change in the total score on the HDRS-21 was more significantly improved in the active group than in the sham group at 6 weeks (p = 0.045). There were no significant differences in the response and remission rates or cognitive measures between the active and sham groups. No serious adverse events were observed in either group.
Conclusions: These results suggest that dTMS might be effective and safe in office workers with treatment-resistant depression. Further well-designed studies are needed.
