Prospective associations among nonverbal reasoning abilities, illness duration, and eating disorder symptoms in anorexia nervosa and bulimia nervosa

In AN, longer illness duration was linked to poorer nonverbal reasoning, whereas in BN, better nonverbal reasoning predicted improvement in symptoms over time. These findings support the relevance of nonverbal reasoning to AN and BN. Future longitudinal studies are needed to confirm the findings and gain additional insights into associations among nonverbal reasoning, illness duration, and ED symptoms.
