Cue-reactivity

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.

The goal of this clinical trial is to evaluate whether closed-loop transcranial magnetic stimulation (TMS) 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 TMS significantly reduce cue-reactivity, as measured by a Visual Analog Scale (VAS) and cue-reactivity task, compared to a conventional treatment protocol and random TMS ? Does closed-loop stimulation enhance cognitive control, assessed by performance on the Stop Signal Task (SST), more effectively than the other stimulation modes? Researchers will compare closed-loop, conventional, and random TMS conditions to determine whether closed-loop yields superior symptom improvement. Participants will: Be randomly assigned to one of the three stimulation group (closed-loop, conventional and random) according to a pre generated random number table, and receive the corresponding stimulation session. Undergo cue-reactivity assessment using VAS and cue-reactivity task, and complete the SST before and after each stimulation session.
