Transcranial Direct Current Stimulation for Depression
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.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Spaced Transcranial Direct Current Stimulation (tDCS)
Trial Overview
The study compares real versus fake (sham) transcranial direct current stimulation (tDCS), a non-invasive brain stimulation, delivered at home under remote monitoring, to see if it helps people with treatment-resistant depression.
How Is the Trial Designed?
2
Treatment groups
Active Control
Placebo Group
Active tDCS applies low-intensity electrical current to the scalp to modulate cortical excitability through subthreshold shifts in neuronal membrane potentials, influencing synaptic plasticity
Sham tDCS is a placebo control that simulates the physical sensations of tDCS but does not deliver any actual, prolonged electrical current to the brain.
