Neuronavigated aiTBS for TRD

Официальное название

Neuronavigated and Non-Neuronavigated Accelerated Intermittent Theta-Burst Stimulation for Treatment-Resistant Depression A Sham-Controlled Randomized Controlled Trial

Обзор

The purpose of this study is to confirm the efficacy of two recently introduced repetitive transcranial magnetic stimulation (rTMS) interventions - accelerated intermittent theta-burst stimulation (aiTBS) and individualized neuronavigation - in treatment-resistant depression (TRD). Using a three-arm design (neuronavigated aiTBS, non-neuronavigated aiTBS, and sham), this randomized controlled trial (RCT) is the first to specifically investigate the incremental benefit of neuronavigation within an accelerated stimulation protocol, as well as the first confirmatory RCT comparing the efficacy of each of these active treatments vs. sham, overcoming previous generalizability issues and being conducted in an independent, multicenter US TRD sample.

Критерии участия

Критерии включения
