Conventional high-frequency repetitive transcranial magnetic stimulation has been employed to treat people with obesity and has shown certain effectiveness. The goal of this clinical trial is to evaluate the efficacy of intermittent theta burst stimulation (iTBS) in ameliorating appetite increase and weight gain induced by antipsychotics in patients with schizophrenia.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and analysis<\/jats:title>\n                  <jats:p>In this randomised, double-blind, sham-controlled trial, 60 participants will be enrolled and allocated (1:1) to receive active or sham iTBS on the dorsolateral prefrontal cortex for 5 consecutive\u2009days. Appetite, body mass index, clinical symptoms, cognitive function and laboratory indicators will be assessed at baseline, after 5\u2009days of treatments, and at 2 weeks and 4 weeks after all treatments. MRI examination will be conducted to detect brain structure, perfusion and functional connectivity. Data analysis will be conducted in a modified intention-to-treat population. The results of the study will provide evidence on the effectiveness and feasibility of iTBS in improving increased appetite induced by antipsychotics and explore the underlying neuroendocrine pathway affected by the intervention. The primary objective is to evaluate the efficacy of iTBS in weight gain in patients with schizophrenia taking antipsychotics. The secondary objective is to identify the neuroendocrine changes related to appetite in response to iTBS by assessing the variables of cognitive control, glucolipid metabolism and brain activity.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Ethics and dissemination<\/jats:title>\n                  <jats:p>The study protocol has been approved by the National Clinical Medical Research Center Ethics Committee of The Second People\u2019s Hospital of Dali Bai Autonomous Prefecture (no: 2023YN3) and The Second Xiangya Hospital (no: 2024K008).
