Mechanisms Of Orbitofrontal Stimulation in Depression

NCT07230990 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 80

Summary

The orbitofrontal cortex (OFC), a region involved in emotional regulation, decision making, and reward processing, is a key area linked to antidepressant response. This study tests whether noninvasive stimulation of the OFC using transcranial magnetic stimulation (TMS) can improve depressive symptoms. TMS uses magnetic fields generated by a coil placed next to the scalp to alter brain activity.

Conditions

  • Major Depressive Disorder (MDD)

Interventions

DEVICE

Sham TMS

The MagVenture MagPro system's active/sham coil (e.g., Cool-B65 A/P) will be used to deliver either active or sham TMS. The sham mode reproduces the same clicking sound and scalp sensation as active stimulation but does not induce cortical activation. The built-in MagPro double-blind feature ensures operator, participant, and investigator blinding. All participants will be randomized to receive active or sham TMS to the OFC in the first phase.

DEVICE

Active TMS

TMS uses magnetic fields generated by a coil placed next to the scalp to alter brain activity at a specific region (i.e., OFC) protocol. Here, active TMS protocol is continuous intermittent theta burst stimulation (cTBS, a type of inhibitory TMS) to the right OFC. Investigators will use the MagVenture MagPro system's active/sham coil (e.g., Cool-B65 A/P) to deliver either active or sham TMS. All participants will be randomized to receive active or sham TMS to the OFC in the first phase. In the second phase, all participants will receive active TMS to the OFC. The active protocol to the right OFC is: continuous intermittent theta burst stimulation (cTBS, a type of inhibitory TMS).
