Advances in Eating Disorder Treatment
Severe and Enduring Eating Disorders: Staging Models and Treatment Resistance
Severe and enduring eating disorders (SE-ED) represent a challenging subset of eating disorders characterized by long durations and multiple unsuccessful treatment attempts. Recent research highlights the potential utility of staging models, particularly in anorexia nervosa, to aid in assessment and inform treatment strategies . However, the effectiveness of these models in other eating disorders remains unclear. Emerging psychological therapies show promise in improving outcomes, although treatment resistance and the need for involuntary care remain significant issues .
Emerging Treatments: Pharmacological and Neuromodulatory Approaches
Pharmacological interventions have historically played a limited role in treating eating disorders, primarily addressing comorbid psychiatric issues like depression and anxiety. Currently, there are no FDA-approved medications for anorexia nervosa, and only fluoxetine and lisdexamfetamine are approved for bulimia nervosa and binge-eating disorder, respectively . However, postmarket monitoring has identified several novel treatment options, including the use of antiepileptic agents like topiramate for weight loss in binge-eating disorder . Neuromodulatory interventions targeting specific brain regions are also showing limited but promising support in pilot studies .
Psychological Treatments: Cognitive Behavioral Therapy and Family-Based Approaches
Cognitive behavioral therapy (CBT) remains the most established treatment for bulimia nervosa and binge-eating disorder, with both full and guided forms showing efficacy . Enhanced CBT has also improved symptoms in both adults and youth . For adolescents with anorexia nervosa, family-based therapy, particularly the Maudsley approach, is the most established treatment and may also be effective for youth with bulimia nervosa . Interpersonal psychotherapy is emerging as a promising approach for preventing excess weight gain and reducing loss of control eating in overweight youth .
Weight Management and Eating Disorder Risk: The EDIT Collaboration
The Eating Disorders In weight-related Therapy (EDIT) Collaboration aims to explore the complex interactions between risk factors that precede changes in eating disorder risk following weight management interventions. While medically supervised obesity treatments generally improve risk scores related to eating disorders, a subset of individuals may experience poor outcomes . The EDIT Collaboration seeks to understand these interactions better and develop strategies to mitigate the risk of eating disorders in weight management contexts .
Treatment Seeking and Unmet Needs
A significant proportion of individuals with diagnosable eating disorders do not seek specific treatment for their condition. A systematic review found that only 23.2% of community cases sought appropriate mental health or medical treatment for their eating disorder, although many received treatment for weight loss . This highlights the need for interventions that help community members and healthcare professionals recognize eating disorders and understand the benefits of timely and appropriate treatment .
Conclusion
The treatment landscape for eating disorders is evolving, with significant advances in psychological therapies, emerging pharmacological and neuromodulatory treatments, and a better understanding of the risks associated with weight management interventions. However, challenges remain, particularly in addressing treatment resistance in severe and enduring cases and improving access to effective treatments. Future research and clinical practice must continue to focus on these areas to reduce the burden of eating disorders.
