Closed-loop TBS Targeting rPO for the Core Clinical Features of the Methamphetamine Use Disorder

The goal of this clinical trial is to evaluate whether closed-loop theta-burst stimulation (TBS) targeting the right parietal-occipital cortex (rPO) can improve core clinical symptoms in individuals with methamphetamine use disorder (MUD), such as cue-reactivity and impaired inhibitory control. The main questions it aims to answer are: Can closed-loop rPO-TBS significantly reduce cue-reactivity, as measured by a Visual Analog Scale (VAS) and a cue-reactivity task? Does closed-loop stimulation enhance cognitive control, assessed by performance on the Stop Signal Task (SST)? Researchers will administer closed loop TBS to determine whether it can improve the core symptoms of MUD. Participants will: Complete a single closed-loop sessions. Receive theta-burst stimulation targeting the right parietal-occipital cortex while complete the cue-reactivity task. Undergo cue-reactivity assessment using a Visual Analog Scale (VAS) and complete the Stop Signal Task (SST) before and after the stimulation session.
