Developing Functional Connectivity-Guided TMS for Alcohol Use Disorder
Sponsor: VA Palo Alto Health Care System
Summary
Alcohol Use Disorders are currently positioned as the third leading cause of preventable death in the United States, constituting a humanitarian crisis with substantial financial burden on society and medical facilities. While several pharmacological interventions exist, 60% of individuals who seek these treatments relapse to alcohol within 6 months. These high relapse rates are due in part to elevated brain response to alcohol cues in the environment. This study seeks to evaluate the efficacy of one session of functional Magnetic Resonance Imaging (fMRI) guided transcranial magnetic stimulation (TMS) as a strategy to reduce brain reactivity to alcohol cues.

Interventions
Active Transcranial Magnetic Simulation
1 session of active continuous theta burst stimulation (3600 pulses, 110% RMT) will be delivered to the cortical region demonstrating maximal functional connectivity with the striatum during alcohol cue presentation. TMS will be delivered using the Magventure MagPro X100.
Sham
1 session of sham continuous theta burst stimulation (3600 pulses, 110% RMT) will be delivered to the cortical region demonstrating maximal functional connectivity with the striatum during alcohol cue presentation. The MagVenture MagPro x100 is capable of administering a sham stimulation. The reverse side of the TMS coil is plated with a magnetic shield such that electromagnetic energy cannot stimulate the brain. The device offers compatibility with Transcutaneous Electrical Nerve Stimulation devices such that titrated electrical pulses can be delivered to the scalp location to mimic the sensation of a TMS pulse without stimulating the brain.
