Background: Eating disorders in the elderly are often overlooked. When they occur, significant morbidity and mortality result. In this study we review all existing literature on eating disorders in the elderly and provide practical guidelines for clinicians in recognizing and managing eating disorders in the elderly.
Methods: A literature search using Medline, PubMed, Web of Knowledge, and PsychINFO revealed 48 published cases of eating disorders in people over the age of 50 years.
Results: The mean age was 68.6 years (range 50-94), and the majority (88%) of cases were females. The majority (81%) of cases had anorexia nervosa, and 10% had bulimia nervosa. Late onset eating disorders were more common (69%) than early onset. Comorbid psychiatric conditions existed in 60%, most commonly major depression. Management with a combination of behavioral and pharmacologic interventions was most successful, although only 42% were treated successfully. Mortality was high (21%) secondary to the eating disorder and its complications.
Conclusion: Eating disorders do occur in the elderly and should be included in the differential diagnosis of unexplained weight loss in the elderly.

Eating disorders among people with and without type 1 diabetes: incidence and treatment in a nationwide population-based cohort.
Diabetologia
January 2025
Department of Public Health, University of Helsinki, Helsinki, Finland.
Aims/hypothesis: Eating disorders are over-represented in type 1 diabetes and are associated with an increased risk of complications, but it is unclear whether type 1 diabetes affects the treatment of eating disorders. We assessed incidence and treatment of eating disorders in a nationwide sample of individuals with type 1 diabetes and diabetes-free control individuals.
Methods: Our study comprised 11,055 individuals aged <30 who had been diagnosed with type 1 diabetes in 1998-2010, and 11,055 diabetes-free control individuals matched for age, sex and hospital district.

The Influence of Negative Affect on Working Memory Updating of Food Stimuli Among Adolescents With Anorexia Nervosa.
Int J Eat Disord
January 2025
School of Psychological Sciences, University of Haifa, Haifa, Israel.
Objective: Difficulty updating information in working memory has been proposed to underlie ruminative thinking in individuals with anorexia nervosa (AN). However, evidence regarding updating difficulties in AN remains inconclusive, particularly among adolescents. It has been proposed that exposure to negative emotion and disorder-salient stimuli may uniquely influence updating in AN.

J Child Psychol Psychiatry
January 2025
National Centre for Register-Based Research (NCRR), Aarhus University, Aarhus, Denmark.
Background: More research is needed to understand psychopathology among parents of children with mental disorders in the years before and after the child is diagnosed. Here, we estimated the risk of mental disorders and psychotropic medication use in parents of children with versus without mental disorders and the temporal associations between child and parental psychopathology.
Methods: We conducted a population-based matched cohort study using Danish register data.
Exploring the relationship between proactive inhibition and restrictive eating behaviours in severe and enduring anorexia nervosa (SE-AN).
J Eat Disord
January 2025
Centre for Research in Eating and Weight Disorders, Department of Psychological Medicine, Institute of Psychiatry, Psychology & Neuroscience, King's College London, London, UK.
Background: There is a need for improved understanding of why 20-30% of individuals with anorexia nervosa (AN) develop a severe and enduring form of illness (SE-AN). Previously, we reported differences in proactive inhibition (a pre-emptive slowing of responses) in individuals with AN compared to healthy controls (after controlling for intolerance of uncertainty). The present study is a preliminary exploration of proactive inhibition in which we compared women with SE-AN with healthy comparison (HC) women and explored its association with restrictive/avoidant eating behaviours.
