Study Summary

This is a prospective clinical trial to confirm the effectiveness of bilateral accelerated theta burst stimulation (aTBS) on suicidal ideation (SI), while exploring cortical inhibition measures in this treatment paradigm. In this proposed study, the investigators will evaluate the anti-suicidal effects of bilateral aTBS over the DLPFC compared to accelerated intermittent theta burst stimulation (aiTBS) over the left DLPFC in participants with TRD and SI. Additionally, the investigators aim to identify neurophysiological targets through which bilateral aTBS induces remission of SI in TRD differentially from aiTBS.

Primary Outcome

The primary outcome will be a comparison of change in score on the suicidality scale index (SSI) from baseline to endpoint of treatment between accelerated bilateral and unilateral treatment. The SSI contains 19 items scored from 0 to 2, higher scores indicating more severity, with overall scores ranging from 0 to 38The primary endpoint will be at treatment completion for both arms. The investigators will follow patients at 1, 2, 3, and 4 weeks post-treatment, as well as 3 and 6 months after tre
