tTIS Targeted of the Striatum as an Intervention for MUD Patients

Targeted temporal interference stimulation (tTIS) of the caudate nucleus can modulate the abnormal electrophysiological activity in individuals with methamphetamine use disorder (MUD), thereby improving their impaired reward-learning behaviors and reducing drug craving.

Effects of Repetitive Transcranial Magnetic Stimulations in Patients With Amphetamine Use Disorders

Amphetamine Use Disorder (AUD) is a major public health issue in Taiwan, where it is the most commonly abused illegal drug. There are currently no effective approved medications to treat it, which makes finding new treatment options urgent. Repetitive Transcranial Magnetic Stimulation (rTMS), a non-invasive brain stimulation method, has shown promise in reducing cravings and drug use in people with addiction, but its effects on AUD are not well studied. To explore this, the investigators plan to conduct a double-blind, sham-controlled study with 20 people diagnosed with AUD. Half will receive real rTMS treatment, and half will receive a placebo-like sham treatment. The treatment targets a specific brain area (the left dorsolateral prefrontal cortex) and will be given 10 times over two weeks. The investigators will assess the effectiveness of rTMS by tracking drug cravings, urine test results, and side effects with follow-up over 12 weeks. The investigators also include brain imaging using near-infrared spectroscopy (NIRS) after the treatment. The study aims to better understand how rTMS might help reduce amphetamine cravings and improve outcomes, potentially leading to new treatment options for AUD.

Closed-loop cTBS for the Core Clinical Features of Methamphetamine Use Disorder

Using specific EEG biomarkers in methamphetamine-dependent individuals, this study systematically probes closed-loop continuous Theta-burst Stimulation (cTBS) based on brain states, assessing dosage, neurologic and behavioral effects, while comparing its efficacy with traditional open-loop cTBS methods.
