Testing an Accelerated TMS Protocol for Methamphetamine Use Disorder
University of Colorado, Denver
Summary
The investigators will evaluate the effects of an accelerated Transcranial Magnetic Stimulation (TMS) protocol of the left dorsolateral prefrontal cortex (DLPFC) for moderate to severe methamphetamine use disorder. This is a randomized parallel group design to assess feasibility and safety, evaluate efficacy (use, craving) and identify magnetic resonance imaging (resting state and cue craving) associated with group/outcomes.
Description
In a randomized double-blind parallel-group sham-controlled design (n=20) administer a 5-day accelerated iTBS protocol (40 treatments) to the left dorsolateral prefrontal cortex during a short inpatient stay. Magnetic resonance imaging will be completed pre-post TMS and participants will be followed for 12 weeks.

Interventions
- DeviceSham TMS
The TMS Cool-B65 A/P coil on its placebo side delivers electrical stimulation to the scalp (e.g., mimicking sensations associated with real stimulation) but does not provide magnetic stimulation to the targeted cortical structure.
- DeviceActive TMS
The TMS Cool-B65 A/P coil delivers magnetic stimulation to targeted cortical structure.
