Transcranial Magnetic Stimulation for Depression

(R33 MDD Trial)

This trial explores how transcranial magnetic stimulation (TMS) affects the brain in people with depression. Researchers aim to determine if changes in the subgenual anterior cingulate cortex (sgACC) can predict improvements in depressive symptoms. Participants will receive either real or sham (fake) TMS treatments over six weeks to compare results. Ideal participants are adults diagnosed with major or persistent depressive disorder who can commit to daily sessions for six weeks. As an Early Phase 1 trial, this research focuses on understanding how TMS works in people, offering participants a chance to contribute to groundbreaking insights.

Research has shown that transcranial magnetic stimulation (TMS) is generally safe for treating depression. Patients usually tolerate it well, as studies have found. For instance, a review of several studies found that TMS significantly reduced depression symptoms without causing severe side effects. Although some studies reported rare cases of serious events like mania and psychosis, these were uncommon.

One study indicated that both standard repetitive TMS (rTMS) and intermittent theta burst stimulation (iTBS) have similar safety levels, showing no major differences in side effects. Concerns about effects on thinking were not supported by the evidence.

Researchers are excited about transcranial magnetic stimulation (TMS) because it offers a non-invasive way to treat depression by directly targeting the brain. Unlike traditional medications that often take weeks to show effectiveness and can have various side effects, TMS uses magnetic fields to stimulate specific brain areas involved in mood regulation. The active intermittent theta burst stimulation (iTBS) being studied is especially promising because it applies this technique more precisely, potentially leading to faster and more effective relief from depressive symptoms. This direct approach could provide a new option for those who haven't found success with standard treatments like antidepressants or psychotherapy.

This trial will compare two forms of transcranial magnetic stimulation (TMS) for treating depression: Active Repetitive Transcranial Magnetic Stimulation (rTMS) and Sham Transcranial Magnetic Stimulation (TMS). Research has shown that TMS can help treat depression, with studies finding significant symptom reduction for some individuals. This treatment uses magnetic fields to stimulate specific brain areas involved in mood regulation. Patients often report feeling better and experiencing fewer symptoms after regular sessions. While results can vary, many have had positive experiences with TMS in managing their depression.⁶⁷⁸⁹
