Cerebellar Repetitive Transcranial Magnetic Stimulation (rTMS) for the Treatment of Alcohol Use Disorder

To achieve study aims, 34 treatment seeking adults with AUD will be recruited from local
intensive outpatient (IOP) treatment programs and randomized to treatment with either
inhibitory 1Hz rTMS to cerebellar vermis given daily for 2 weeks (total of 10 sessions) or
sham. Alcohol use outcomes, self-reported negative affect, and craving will be obtained at
baseline, 1 day, 1 week and 6 weeks following rTMS termination. An fMRI scan during a Stroop
task will be obtained at baseline and 1 day after the final rTMS session.
