The Effect of Theta-burst Stimulation on Serum BDNF

Summary

The goal of this clinical trial is to investigate the effect of theta burst stimulation for depression and serum brain-derived neurotrophic factor (BDNF) in individuals with major depression. The main question it aims to answer is whether 10 sessions of theta burst stimulation can influence the serum level of BDNF. Participants will be randomized into active group and sham group. Researchers will compare the level of BDNF in these groups.
