What You Need to Know Before You Apply

What is the purpose of this trial?

This study aims to evaluate the clinical efficacy and neurophysiological mechanisms of home-based spaced tDCS in TRD through a randomized, double-blind, sham-controlled trial conducted under remote supervision. Specifically, this trial will: (1) compare the efficacy of active versus sham spaced tDCS on depressive symptom severity in individuals with TRD and (2) characterize neurophysiological changes associated with spaced tDCS using TMS-EEG, TMS-EMG and resting state EEG.

Are You a Good Fit for This Trial?

This trial is for adults with major depressive disorder who have not improved after trying other depression treatments. Participants must be able to use the tDCS device at home and take part in remote supervision.
