A Study on Multitarget Magnetic Modulation Based on Neural Network Endophenotypes in Attention-Deficit/Hyperactivity Disorder (ADHD)

INTERVENTION: Group 1:Single‐target Transcranial Magnetic Stimulation;Group 2:Multi‐target Transcranial Magnetic Stimulation; CONDITION: Attention‐Deficit/Hyperactivity Disorder PRIMARY OUTCOME: Clinical symptoms assessed using the SNAP‐IV questionnaire.; SECONDARY OUTCOME: Weiss Functional Impairment Rating Scale (WFIRS);Phase Lag Inde X(PLI);The Conners' Parent Rating Scale (CPRS);Safety evaluation: general vital signs, neurological adverse events, hearing impairment, local scalp reactions, cognitive and emotional adverse events, and serious adverse events (SAEs).; INCLUSION CRITERIA: 1.Aged 3–18 years, with no gender restriction; 2.Meet the diagnostic criteria for ADHD (attention‐deficit subtype or combined subtype) according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM‐V); 3.Full‐scale IQ >= 70 as assessed by the Wechsler Intelligence Scale for Children (Chinese Revised Edition, Second Version); 4.Not using methylphenidate, atomoxetine, traditional Chinese medicines (e.g., Duodongning Capsules, Xiao’er Zhili Syrup, Jingling Oral Liquid, or other Chinese herbal formulas) or other ADHD medications, or have discontinued such medications for at least 2 weeks prior to screening; 5.The guardian agrees to participate and cooperate with the study, and voluntarily signs the informed consent form;
