Mini Theta Burst TMS to Promote Brain Plasticity Indexed by fMRI in MDD Patients
In Brief
A clinical study evaluating Transcranial Magnetic Stimulation for Major Depressive Disorder. Completed, enrolled 41 participants across 1 site.
Detailed Summary
This is not a treatment study. In this study, the researchers are primarily interested in examining whether functional MRI (fMRI)-guided transcranial magnetic stimulation (TMS) may be more effective than traditional TMS methods at temporarily influencing neural circuit communication. The investigators test this by combining TMS and fMRI technologies to probe and modulate brain activity. If the novel fMRI-guided TMS stimulation used in this study is more effective than traditional methods, future studies may utilize similar personalized TMS targeting methods to yield even better clinical outcomes.
Study Details
Timeline
Interventions
Transcranial Magnetic Stimulation (TMS) is a non-invasive form of brain stimulation. TMS can influence activity in various brain regions, and it allows researchers to test or modify brain circuit communication. Repetitive TMS (rTMS) is FDA-approved for depression treatment. TMS is administered over 5 study visits: an initial TMS/fMRI session, a 3-day TMS intervention regimen, and a post-intervention TMS/fMRI session. During TMS/fMRI sessions, participants receive single pulses of TMS pre/post a short round of Intermittent Theta Burst Stimulation (iTBS), a modified rTMS protocol. Throughout the 3-day intervention regimen, participants receive two full rounds of iTBS daily. All study participants receive active TMS.
