Comparing the Efficacy of Accelerated Vs. Standard FMRI-guided ITBS in Treating Adolescents Depression

Depression | Depressive Disorder, Major

Repetitive transcranial magnetic stimulation (rTMS) is a Health Canada approved treatment for major depression. Theta burst stimulation (TBS), a type of rTMS, is a very promising new treatment for major depression in adults and adolescents. However, very few studies have assessed the efficacy of accelerated, three times a day TBS in comparison with standard once a day TBS in adolescents. The study aims to explore further evidence in hopes to conduct a large-scale, randomized, multisite, placebo-controlled clinical trial evaluating the effects of a functional magnetic resonance imaging (fMRI)-guided accelerated rTMS protocol vs. standard once/daily rTMS for treatment-resistant depression in adolescents.

9. Unwilling to maintain the current antidepressant regimen.
10. Taking more than 1 mg/day of lorazepam or equivalent.
