研究概览
简要总结
This small pilot trial will recruit 10 cannabis use disordered participants and apply 20 sessions of rTMS in conjunction with a two session Brief Marijuana Dependance Counseling treatment paradigm. The investigators are primarily seeking to determine if the proposed paradigm is feasible and well tolerated.
详细描述
The overarching goal of this proposal is to investigate if a course of excitatory DLPFC rTMS is feasible and well tolerated by a group of treatment seeking CUD patients (Aim1). The investigators are also hoping to preliminarily determine if a course of rTMS reduces cannabis cue-induced craving (Aim2). Additionally the investigators want to preliminarily explore the mechanistic underpinnings of any observed effect by collecting functional magnetic resonance imaging (fMRI) data during cannabis cue-administration before and after the treatment course (Aim 3). These aims will be addressed through an open label study in which 10 treatment seeking cannabis use disordered participants will be given 20 sessions of Active excitatory rTMS applied to the DLPFC. TMS will be delivered in an accelerated fashion over two weeks (2 sessions each day, five days each week). TMS will be applied in conjunction with a validated two-session Motivational Enhancement Therapy (MET) behavioral intervention.
