Study Summary

The overarching goal of this project is to examine the effect of combining theta burst stimulation (TBS) and N-acetylcysteine (NAC) on cocaine craving and brain response to cocaine-related images.

Primary Outcome

Measured using fMRI during cocaine cue reactivity task. Percent BOLD signal change in OFC from baseline (Visit 2) to post-TBS (Visit 3). Measured using functional MRI during a cocaine cue reactivity task. The outcome reflects the change in raw BOLD signal in the orbitofrontal cortex (OFC) between baseline and post-TBS sessions. Signal change was calculated by comparing activation during cocaine-related image blocks versus neutral image blocks. Values are reported as raw BOLD signal units (not pe

Interventions

  • DRUG N-acetylcysteine
  • DEVICE Theta-burst stimulation (TBS)
