Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Currently, rare studies have been conducted on dTMS targeting ACC as an intervention in patients with AN. In this research, dTMS, a neuroregulatory technology, is used for the first time to intervene with ACC in the treatment of adult AN. A randomized controlled study design is adopted, in which patients with AN are divided into the dTMS treatment group and the pseudo-stimulation group by 1:1 randomization, followed by a 28-day intervention (once a day) and half-year follow up, to clarify the near-term and long-term efficacy and safety of the dTMS treatment. Patients in both groups undergo fMRI examinations, complete delay discounting task (DDT) and body image task before and after each treatment session. Efficacy is judged by a weight gain of 4 kg in the four weeks following the intervention. Symptoms, psychometrics and side effect questionnaires are followed up at baseline, day 28 (at the end of treatment), and weeks 4, 8, 12 and 24 ( after completion of treatment).
Meanwhile, baseline fMRI data will be extracted and combined with clinical features to establish an efficacy prediction model. We will explore factors predictive of dTMS efficacy in AN patients of dTMS treatment group, divided into two groups according to whether dTMS is effective or not after treatment (defined as a weight gain of 4 kg in the four weeks following the intervention), using pre-treatment (baseline) demographic information, psychological assessment questionnaires, and neuroimaging data in the two groups. This will provide theoretical and practical basis for the pioneering ACC-targeted dTMS treatment in China, helping to establish a new type of intervention program for AN, with expected results of innovation.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
dTMS treatment group
dTMS treatment group has 40 patients with dTMS intervention using real coils, targeting ACC, given once per day, for 28 days, with a total of 28 treatments.
Deep transcranial magnetic stimulation
Neuronavigation: The coil is positioned 4cm in front of the scalp point and foot motor cortex, corresponding to the ACC. The Brainways H7 coil with fluid cooling is used to obtain a greater depth of stimulation, up to about 6 cm below the cortex.
dTMS intervention: The intervention targets are at the left and right ACC, once per day, for 28 days. A total of 28 treatments are given. Stimulation mode: stimulation frequency 1Hz, stimulation intensity 100% RMT, number of pulses 150, sequence interval 20s, total 6 trials, 900 pulses.
Basic treatment
According to national and international guidelines for the treatment of eating disorders, the basic treatment for patients is nutritional therapy, that is, regular and quantitative dietary treatment, with three regular meals followed by a snack meal 2 hours after the regular meal. Both groups received the same nutritional treatment.
pseudo-stimulation group
Pseudo-stimulation group has 40 patients with dTMS intervention using sham coils (with the same parameters as real dTMS and generating the same noise as real coils, but without the magnetic field). It is given once per day, for 28 days, with a total of 28 treatments.
Sham deep transcranial magnetic stimulation
Neuronavigation: The sham coil is positioned 4 cm in front of the scalp point and foot motor cortex, corresponding to the ACC.
Sham dTMS intervention: The intervention targets are at the left and right ACC (The sham coil has the same parameters as real dTMS and generating the same noise as real coils, but without the magnetic field), once per day, for 28 days. A total of 28 treatments are given.
