Brief Summary
We will perform a randomized sham-controlled trial of aiTBS to an anxiosomatic circuit in patients with anxiety-related disorders (i.e., panic disorder, generalized anxiety disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder). 80 participants with an anxiety-related disorder (defined below) will receive 50 active or sham TMS treatments over 5 days (following the SAINT protocol, which is FDA-cleared for MDD. The primary outcome will be the BAI, with a modified recall window to reflect the short treatment interval. Participants randomized to sham will be offered an open-label crossover extension.

Study Arms (2)
Real aiTBS
ACTIVE COMPARATORParticipants in this group will receive aiTBS with neuronavigation to the anxiosomatic treatment target.
Sham aiTBS
SHAM COMPARATORParticipants in this group will receive sham aiTBS with neuronavigation to the anxiosomatic treatment target.
Interventions
Transcranial magnetic stimulation (TMS) is a focal, non-invasive form of brain stimulation that has FDA clearance for depression. In this study, a form of TMS called accelerated intermittent theta burst stimulation will be administered under the supervision of a physician with TMS expertise.
The sham TMS coil mimics the scalp sensation of real TMS by delivering a small amount of electrical current with a pair of surface electrodes.
