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.
Inclusion Criteria: * People between the ages of 18 and 70 at the time of screening. * Able to read, understand, and provide written, dated informed consent prior to screening. Proficiency in English sufficient to complete questionnaires / follow instructions during interventions. Stated willingness to comply with all study procedures, including availability for the duration of the study, and to communicate with study personnel about adverse events and other clinically important information. * Currently diagnosed with Major Depressive Disorder (MDD) and meets criteria for a Major Depressive E…
Spaced-tDCS will be self-administered at home under the supervision of a trained clinical research coordinator using the Soterix Medical mini-CT device with remote monitoring via a secure videoconferencing platform (e.g., Microsoft Teams).
Soterix Medical mini-CT device sham protocol that match real stimulation parameters will be used.
