메스암페타민 사용 장애에 대한 가속 TMS 프로토콜 테스트
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.

상세 설명
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.

위약 비교기: Sham TMS
Participants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of sham TMS, and then have weekly study visits for the next 12 weeks. |
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. |

실험적: Active TMS
Participants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of active TMS, and then have weekly study visits for the next 12 weeks. |
The TMS Cool-B65 A/P coil delivers magnetic stimulation to targeted cortical structure. |
