What this trial studies

This research project aims to explore the neurological, physiological, and behavioral factors associated with anorexia nervosa in adolescents. Over three years, the study will follow 100 girls aged 13-17, including 50 with anorexia nervosa and 50 healthy controls, using structural and functional magnetic resonance imaging (fMRI) alongside physiological measurements and questionnaires. The study also includes an investigation of intestinal microbiota and a cardiac sub-study involving MRI and ultrasound examinations. Participants will be monitored annually, with fMRI scans repeated at the final visit to assess changes over time.

Who should consider this trial

Good fit: Ideal candidates include females aged 13-17 with a body mass index less than 17.5 kg/m2 who meet the diagnostic criteria for anorexia nervosa.

Not a fit: Patients with chronic illnesses or other mental disorders, as well as those who smoke or abuse substances, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved methods for predicting and influencing the course of anorexia nervosa in adolescents.

How similar studies have performed: Other studies have shown promise in understanding anorexia nervosa through similar neurological and physiological approaches, but this specific combination of methods is relatively novel.
