pBFS-Guided rTMS Therapy Over Different Targets for Treatment-Resistant Depression

ClinConnect Summary

This clinical trial is investigating a treatment called repetitive Transcranial Magnetic Stimulation (rTMS) for adults with major depressive disorder who have not responded well to other treatments. Researchers want to see how effective this therapy is when aimed at different areas of the brain, specifically using a method called pBFS to find the best target for stimulating brain activity. The goal is also to understand which parts of the brain respond to this treatment, which could help improve future therapies for depression.

To join the trial, participants should be between 18 and 65 years old and have been diagnosed with depression according to specific guidelines. They must have experienced a recent episode of depression and have not found relief from at least one antidepressant treatment. Participants will need to sign consent and attend regular appointments to receive the rTMS therapy and help with the study. It's important to note that certain health conditions or previous treatments may prevent someone from participating, so potential volunteers should discuss their medical history with the research team.
