简要总结
This pilot study aims to compare two different treatment targets for transcranial magnetic stimulation, an FDA-approved treatment for major depressive disorder (MDD), in terms of their relative efficacy for depression versus anxiety.
详细描述
Transcranial magnetic stimulation (TMS) is a safe, noninvasive FDA-cleared technique that is commonly used as a treatment for MDD. It has been shown to focally activate specific brain regions that are believed to be underactive in these patients. This study aims to compare two different TMS targets in the prefrontal cortex. TMS will be administered within FDA-approved guidelines under the supervision of a physician with experience in administering the treatment and monitoring for complications.
This will be a prospective double-blind randomized controlled trial to assess the comparative efficacy of two different TMS targets within the prefrontal cortex (PFC). The "dysphoric" target in the dorsolateral PFC is believed to be more effective for depression, while the "anxiosomatic" target in the dorsomedial PFC is believed to be more effective for anxiety.
Patients with comorbid depression and anxiety will receive 6 weeks of TMS following standard clinical parameters (30 treatments over 6 weeks, 10 Hz frequency, 3000 pulses) with MRI-guided neuronavigation. Participants will be randomized to either the dysphoric or anxiosomatic target. Both targets are believed to be effective treatments for this patient population. Participants and raters will remain blinded to the group assignment. All participants will receive resting-state functional MRI scans before and after the course of treatment in order to study physiological changes.
The dysphoric target is expected to induce greater relative improvement in depression, while the anxiosomatic target is expected to induce greater relative improvement in anxiety.
