Personalized Transcranial Magnetic Stimulation (TMS) for Metabolic Dysfunction and Alcohol-Related Liver Disease

The goal of this clinical trial is to learn if repetitive Transcranial Magnetic Stimulation (rTMS), a non-invasive brain stimulation technique, works to treat Metabolic dysfunction-associated and alcohol-associated liver disease (MetALD). The main questions it aims to answer are: * Can rTMS effectively treat MetALD? * Is an individualized, precision-targeted rTMS approach more effective than the standard rTMS method? * What changes in brain activity are associated with the treatment? Researchers will compare three different types of stimulation: * Group A: Individualized rTMS targeting a deep brain reward area (the Nucleus Accumbens) based on each participant's brain scan (fMRI). * Group B: Standard rTMS applied using the traditional "5 cm" rule for positioning. * Group C: Sham (placebo) rTMS, which mimics the procedure but delivers no significant magnetic stimulation. Participants will: * Be randomly assigned to one of the three groups (A, B, or C). * Undergo an MRI brain scan before starting treatment. * Receive a total of 20 rTMS sessions, completing at least 4 sessions per week. * Have additional MRI scans and clinical assessments halfway through and immediately after the treatment course. * Attend follow-up visits at 1, 3, and 6 months after treatment completion to assess long-term effects.
