Accelerated vs. Conventional Theta Burst Stimulation for Late-life Depression

Sponsor: Centre for Addiction and Mental Health

View on ClinicalTrials.gov

Summary

The purpose of this trial is to compare the treatment efficacy (improvement in depressive symptoms) of accelerated TBS protocol (where participants receive multiple TBS treatments daily) to conventional TBS protocol (where participants receive a single TBS treatment daily) in late life depression. In addition, the study also aims to determine if specific patterns of stimulation are more or less effective. To do this, all participants will receive active treatments, but some of the participants in this study will receive accelerated TBS and some will receive once daily TBS.

DEVICE

TBS

Repetitive transcranial magnetic stimulation (rTMS) is a form of non-invasive neurostimulation that uses focused magnetic field pulses to directly stimulate cortical neurons. Theta burst stimulation (TBS) is a briefer form of patterned rTMS that has been shown to be effective against major depressive disorder. Each treatment will consist of either 1) cTBS of right DLPFC followed by iTBS of left DLPFC; or 2) iTBS of left DLPFC.
