ADHD and eating disorders in childhood and adolescence: An updated minireview

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders with overactivity, inattention, and impulsivity as core characteristics. Recent studies suggest that 20 % of children with ADHD also develop eating disorders (EDs), including anorexia nervosa, bulimia nervosa and binge eating disorder. However, little is still known about the association between ADHD and EDs through childhood and adolescence. Therefore, in the present work, we aimed at summarizing the studies investigating ADHD and EDs in childhood and adolescence over the last 10 years.Methods: A bibliographic search on PubMed was performed and only studies that considered participants with a clinical diagnosis of ADHD, patients with an additional diagnosis of EDs and patients under 18 years old were included. A total of 7 studies were retrieved and included in the review.Results: The majority of the reviewed studies (N = 5) found an association between ADHD and EDs, while the remaining, which focused on EDs symptomatology, reported either lower ED symptoms in ADHD sample or no association between ADHD and EDs.Limitations: the majority of studies were cross-sectional and therefore did not allow to explore the longitudinal casual relation between ADHD and EDs in the developmental age range considered.Conclusions: This review suggests that children and adolescents with ADHD should be monitored for EDs. However, more work is still needed to better understand the clinical implications of the comorbidity between ADHD and EDs and its prospective impact on the life of children and adolescents with ADHD.

Automated summary

ADHD is a common neurodevelopmental disorder characterized by overactivity, inattention, and impulsivity. Recent studies have found that 20% of children with ADHD also develop eating disorders, such as anorexia nervosa, bulimia nervosa, and binge eating disorder. However, the association between ADHD and eating disorders during childhood and adolescence is not yet well understood.
