Plain-language summary
BACKGROUND: Binge eating disorder (BED) is the worldwide most-prevalent eating disorder. It is associated with psychiatric comorbidities and obesity, a high impact in life functioning, and high morbidity and mortality. First symptoms appear frequently in youths, who most commonly present incomplete (subthreshold) criteria for BED (precursor forms, PREC-BED). While some subjects will evolve from PREC-BED to BED, there is no gold standard to identify the clinical evolution. Information from prior studies suggest early alterations in reward and inhibitory brain circuits in PREC-BED may predict increased vulnerability or resilience to develop BED. Tools based on MRI brain connectivity analyses (MRI-BC), built on robust and interpretable connectivity whole-brain models, have proven successful in diagnostic classification and predicting certain clinical outcomes. OBJECTIVES: To study MRI-BC diagnostic markers of PREC-BED and to explore prognosis at 1 year of follow-up in a sample of adolescents with obesity (12-17 years old). METHODS: A) Transversal analytical design: 3-group (n=34 per group) comparison of neuroimaging (MRI-BC), neurocognitive and clinical markers in adolescents with obesity and i) BED, ii) PREC-BED, iii) no BED nor PREC-BED (Healthy group, HC). B) Longitudinal analytical design, pilot, exploratory: adolescents with PREC-BED will be evaluated in clinical and neurocognitive variables at 1 year. Baseline brain neuroimaging variables (alone and in combination with clinical and neurocognitive variables) will be analyzed as predictors of clinical prognosis, including conversion to BED.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients derived to the Endocrinology Department with obesity as the main criterion for consultation, measured as body mass index (BMI) z-score above 2 standard deviations.
* Age between 12-16 years old.
* Signed informed consent by parents or legal guardians of subjects, plus the signed consent by the adolescent when being 12 or older years/old.
Additional inclusion criteria for the BED and PREC-BED groups:
* The presence of DSM-5 criteria for BED in the BED group.
* Fulfilling the LOC (loss of control) criteria (related to the original Marcus\&Kalarchian) in the PREC-BED group.
Exclusion Criteria:
* Intelligence quotient \< 70 measured with the K-BIT.
* Any comorbid psychiatric disorder, except BED in the BED group or PREC-BED in the PREC-BED group. Tobacco use and the presence of an adaptative disorder or any mild anxiety disorder will be accepted in all groups.
* Traumatic brain injury or any neurological disorder.
* Use of dental braces (due to important artifact in MRI).
* MRI: Absolute contraindications (e.g.: metal objects), relative contraindications (claustrophobia). Anthropometric measures: Weight \> 150Kg or shoulder to shoulder measurement \> 70 cm.
* Any severe medical conditions (including Sleep apnea-hypopnea syndrome), except for obesity and metabolic syndrome.
* Not signing the informed consent.
* Pregnancy for females.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
