Effect of rTMS on Anxiety

Effect of rTMS on Anxiety

Given the overall lack of treatment adherence/efficacy, side effects of drugs, and the substantial burden of anxiety disorders on the individual and on the national healthcare system, there is a critical need for mechanistic research into the CNS mechanisms that underlie these disorders. Accordingly, the objective of this grant is to use noninvasive neuromodulation to causally identify the key neural mechanisms that mediate the cognitive symptoms of anxiety. This project is relevant to public health because it has the potential to lead to novel repetitive transcranial magnetic stimulation treatments for pathological anxiety.

Device - rTMS to the right dlPFC

A Magventure MagPro 100X stimulator with a B65 active/placebo figure-8 coil will be used. The TMS coil will be placed on the head over the target. rTMS intensity will be 100% of the motor threshold (MT), adjusted for field strength difference at motor cortex and target cortex using the individual E-field model. Subjects will receive 3000 pulses/session.
