Post-Traumatic Stress Disorder (PTSD) refers to a mental illness that develops after an individual experiences a significant trauma or life-threatening event. In recent years, repetitive transcranial magnetic stimulation (rTMS) has gradually been applied to the treatment of PTSD. This article aims to review the research on rTMS treatment for PTSD, clarifying its therapeutic parameters, mechanisms of action, safety, and adverse reactions, with the hope of providing guidance for clinical practice.
