This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for improvement of depressive symptoms and drinking behavior in individuals with alcohol dependence. In this open label study, all participants will receive accelerated theta-burst stimulation.
Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive procedure and an established technology. Research utilizing rTMS in patients with alcohol use disorder has shown some promising results. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session). Recently, researchers have aggressively pursued modifying the treatment parameters, such as using accelerated intermittent theta-burst stimulation (aiTBS), to reduce treatment times with possible enhanced efficacy with some preliminary success. This study intends to further modify the parameters to create a more rapid form of the treatment and look at the change in neuroimaging biomarkers.

| Accelerated theta burst treatment | Device | All participants will receive iTBS (intermittent theta burst stimulation) to the left DLPFC. The L-DLPFC will be targeted utilizing the Localite neuronavigation system. Stimulation intensity will be standardized at 80% of resting motor threshold adjust to the skull to cortical surface distance. Stimulation will be delivered to L-DLPFC using the MagPRo stimulator. |

| Change from baseline Montgomery Asberg Depression Rating Scale (MADRS) | A ten item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. The MADRS uses a 0 to 6 severity scale, scored following the interview. Scoring/Interpretation: Higher scores indicate increasing depressive symptoms. ... Cut-off points include: 0 to 6 - symptom absent, 7 to 19 - mild depression, 30 to 34 - moderate, 35 to 60 - severe depression. | Baseline and immediate post-stimulation |

| Change in functional connectivity from baseline as measured by MR imaging | Pre- and post resting state functional connectivity and structural T1-weighted MRI scans to determine the anti-correlated LDLPFC and SCC treatment location. The identified cluster with the greatest anti-correlation between the LDLPFC and SCC will have been utilized for the targeted aiTBS treatment. This algorithm will have also been applied to the post-imaging sessions to give measurements of voxel-wise blood flow in this anti-correlation targeted brain ROI. |
