The recent systematic review and meta-analysis by Inal-Kaleli et al. is situated within a growing area of research, investigating the relationship between anorexia nervosa and autistic characteristics. Their synthesis of research within the topic finds support for elevated autistic characteristics and autism in individuals with anorexia nervosa and a small but significant correlation between autistic traits and level of eating disorder symptoms. In this commentary, we discuss the findings of Inal-Kaleli and colleagues and propose further research to generate insights into the nature of this link. We focus on the potential origins of the observed relationship, specific mechanisms, and manifestation of anorexia nervosa in autistic populations, and the influence of sex and gender on the intersection of eating disorders and autism. By addressing these largely unexplored research avenues, future investigations can go beyond the phenotypic correlations and facilitate the development of prevention and intervention suited for individuals experiencing both disordered eating and elevated autistic traits.

Introduction: Overvaluation of shape and weight is a critical component in understanding and diagnosing eating disorders. While the transdiagnostic model states that overvaluation of shape and weight is the core pathology of all eating disorders, this concept is not a criterion for binge-eating disorder. The lack of recognition of overvaluation of shape and weight may lead to overlooking, and consequently failure to address this construct during treatment.

Objective: Anorexia nervosa (AN) is associated with disturbances in reward processing, cognitive control, and body image perception, implicating striatal dysfunction. Evidence suggests that underweight may modulate brain function in AN. We aimed to investigate whole-brain resting-state functional connectivity (rsFC) of the striatum in patients with AN while controlling for the acute effects of underweight.

Two recent review papers published in the International Journal of Eating Disorders have considerably elevated the rigor of scholarship on the comorbidity between autism spectrum disorder (ASD) and eating disorders. One paper reported that more than one-quarter of individuals with acute anorexia nervosa also have ASD, and that autistic traits are positively correlated with eating disorder psychopathology. The other paper reported that, compared to individuals with low autistic traits, those with high autistic traits report poorer experiences of eating disorder treatment, despite similar treatment outcomes.
