What this trial studies

This project involves a 4-week randomized trial comparing the effects of pre-meal vagal nerve stimulation (taVNS) to sham stimulation in adolescents with anorexia nervosa. The study aims to assess whether taVNS leads to greater meal satisfaction, increased calorie intake, reduced feelings of fullness, decreased eating disorder symptoms, and lower anxiety levels compared to sham stimulation. Participants will undergo a series of assessments, including eating behavior measurements and self-report questionnaires, during five scheduled visits throughout the intervention period.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 14-22 who are engaged in standardized refeeding and need to gain at least 8 lbs during the intervention.

Not a fit: Patients with gastrointestinal disturbances, recent GI surgery, or acute suicide risk may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve eating behaviors and overall well-being in adolescents with anorexia nervosa.

How similar studies have performed: While the use of vagus nerve stimulation is a novel approach in this context, similar studies have shown promise in other conditions, suggesting potential for success.
