“…The limited research investigating this question found that ON is unrelated to performance on traditional neuropsychological assessments of executive function. Namely, ON symptomatology was unrelated to performance on the Wisconsin Card Sorting Test and Trail Making Test that assess cognitive flexibility or set shifting [32,33], and unrelated to performance on the Stroop Task, Go/No-Go Task, and Flanker Task that assess inhibitory control or response inhibition [32,34]. These initial findings suggest that ON is not associated with executive dysfunction.…”

This research explored whether orthorexia nervosa is associated with deficits in executive function.Method: Participants (n = 405; 80% women, 53% White, mean age = 24, mean body mass index = 25) completed the Orthorexia Nervosa Inventory (ONI) and the Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A).Results: ONI scores were significantly correlated with all BRIEF-A scales, exhibiting the strongest correlations with the scales assessing behavioral regulation: Set Shifting, Inhibition, Emotional Control, and Self-Monitoring. Hierarchical regression analyses revealed that these relationships remained significant after controlling for demographic variables (e.g., gender, body mass index, age, education level) and diagnoses of an eating disorder, obsessive-compulsive disorder, attention deficit/hyperactivity disorder, autism, and learning disability. Conclusion:These findings suggest that, despite unique manifestations, orthorexia and anorexia may possess an overlapping neuropsychological profile marked by deficits in executive function, which may negatively impact daily life.
