Efficacy, Tolerability, and Cognitive Effects of Deep Transcranial Magnetic Stimulation for Bipolar Depression

Summary

The aim of this study is to evaluate the feasibility and efficacy of deep transcranial magnetic stimulation (dTMS) as an add-on treatment for bipolar depression. Meanwhile, we aim to evaluate the effect of dTMS on cognitive function of bipolar depressive patients. We hypothesize dTMS would improve depressive symptoms and cognitive function in bipolar disorder.
