Study Summary
The investigators propose a randomized 3-arm double-blinded parallel experimental trial (20 sessions over 4 weeks) in 75 patients with TRD. The three arms include (1) the combination of a fully Individualized form of intermittent Theta Burst Stimulation (iTBS) (using BOTH the frequency and electric field (E-field) targeting approaches) (Ind-iTBS)), (2) iTBS individualized using E-field targeting only (targeted-iTBS) and (3) Standard iTBS treatment (i.e., typical iTBS localized to the dorsolateral prefrontal cortex (DLPFC) using the Beam F3 method). Electroencephalography (EEG) data will be collected at rest and during a working memory task, at baseline, and at the end of treatment along with clinical assessments of depression severity. The target engagement dependent variable of interest in these three arms will be fronto-parietal theta connectivity measured through resting-state EEG. The investigators hypothesize that stimulation with Ind-iTBS will lead to greater changes in fronto-parietal theta connectivity than that produced with targeted-TBS and standard iTBS. Aim: To evaluate the effects of two individualized forms of iTBS (i.e., using BOTH the frequency and E-field individualization; Ind-iTBS) compared to iTBS individualized for E-field targeting only (targeted-iTBS) and standard iTBS on fronto-parietal theta connectivity. Hypotheses: (1) Ind-iTBS will lead to greater changes in fronto-parietal theta connectivity compared to both targeted-iTBS and standard iTBS. (2) Ind-iTBS will also lead to a greater reduction in depressive symptoms (as defined by the mean reduction in Montgomery Åsberg Depression Rating Scale Scores (MADRS)) compared to both targeted-iTBS and standard iTBS.
Primary Outcome
Source-localized fronto-parietal theta connectivity will be calculated from resting EEG
