ClinConnect Summary

This clinical trial is looking at a treatment called repetitive Transcranial Magnetic Stimulation (rTMS) to help adults with major depressive disorder who haven't found relief from previous treatments. The researchers want to see how effective and safe rTMS is when aimed at different areas of the brain, specifically the left prefrontal cortex, by using a special method to identify the best target. They will also analyze brain images to understand how this treatment works and determine the most effective approach for patients with depression.

To participate in this trial, individuals aged 18 to 65 who are experiencing a significant depressive episode and have not responded well to at least one antidepressant treatment may be eligible. Participants should be willing to sign consent forms and comply with the study's requirements. Throughout the trial, participants will receive rTMS treatment and undergo evaluations to monitor progress. It’s important to note that some individuals, such as those with certain medical conditions, a history of seizures, or those currently pregnant or breastfeeding, may not be able to join. If you think you might qualify or are interested in learning more, keep an eye out for more details as the study begins recruiting participants.
