Association of Elevated Reward Prediction Error Response With Weight Gain in Adolescent Anorexia Nervosa.
CONCLUSIONS: Reward system responsiveness is elevated in adolescent anorexia nervosa when underweight and after weight restoration. Heightened prediction error activity in brain reward regions may represent a phenotype of adolescent anorexia nervosa that does not respond well to treatment. Prediction error response could be a neurobiological marker of illness severity that can indicate individual treatment needs.
