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

This is a randomized, double-blind, sham-controlled study to detect the effect of dTMS for treatment of bipolar depression. 100 participants were randomly assigned 1:1 to dTMS group or sham-control group. For both active and sham group, daily dTMS sessions were scheduled in a 5-day sequence for four consecutive weeks, and each session lasted 20minutes. Based on the original and stable medication, the active stimulation consisted of 55 18 Hz, 2 s trains at 120% motor threshold (MT) intensity, with a between-train interval of 20 s (1980 pulses per day or 39 600 pulses per treatment). The sham stimulation was performed using the same procedures, with the sham coil. Scale assessments are performed at baseline, week 2, week 4 and week 8. Collection of blood took place at baseline, week 4 and week 8.
