Anorexia nervosa is one of the most frequent chronic disorders of adolescence associated with a high mortality. During the COVID-19-pandemic, the number of hospitalized children and adolescents with anorexia nervosa significantly increased. This article outlines new research findings to decode the etiology of this serious disorder, especially a genetic disposition and changes of metabolism. Against the background of increasing rates during the COVID-19 pandemic, the importance of the gene-environment interaction is discussed, and new treatment forms are described. Besides the development of new biological treatment strategies, there is also some important progress in psychotherapeutic interventions. Carers should always be integrated when treating children and adolescents with anorexia nervosa, which is especially emphasized in the new "home treatment" setting. The new concept of anorexia nervosa as a metabo-psychiatric disorder gives us hope for new research ideas and treatment strategies in this often-debilitating disorder of childhood and adolescence.

Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) often share multiple similar symptoms and are highly comorbid; however, the common and distinct brain neuroanatomy of these two diseases are unclear. The current study attempted to identify the overlapping and different gray matter volume (GMV) between AN and OCD. We conducted a voxel-wise meta-analysis of GMV using the latest Seed-based d Mapping with Permutation of Subject Images Toolbox (SDM-PSI) software.

Objective: Obsessive compulsive disorder (OCD) and anorexia nervosa (AN) are conditions associated with poor cognitive flexibility, a factor considered to interfere with treatment, but research into the relationship between cognitive flexibility and treatment outcome is limited. This study explores whether baseline measures of cognitive flexibility predict outcomes in OCD and AN, evaluates whether changes in these measures contribute to treatment outcome, and evaluates the effectiveness of adjunctive cognitive remediation therapy (CRT) in improving cognitive flexibility.
Methods: This secondary analysis utilized linear mixed model analysis on data from a randomized controlled multicenter clinical trial involving adult participants with OCD (n=71) AND AN (n=61).

Objectives: Refeeding syndrome (RS) defines the deleterious clinical and metabolic changes occurring during nutritional support of severely malnourished patients. Pediatric guidelines to prevent and treat RS are scarce and highly variable. This study aimed to evaluate the effectiveness and safety of an enteral refeeding protocol in severely undernourished hospitalized children with anorexia nervosa (AN) or organic diseases (OD).

Background: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with multisystemic involvement and unclear etiology. Although SLE could be linked to multiple neuropsychiatric manifestations, the co-occurrence of anorexia nervosa was only described through a few case reports that mainly affected children and adolescents.
Case Presentation: a 40-year-old Filipina woman presented to hospital with a 3-day history of agitation, anorexia and auditory hallucinations.

Background: Currently, we know little regarding how stigma attributed to eating disorders compares to that of other psychological disorders and additionally within different types of eating disorders. In the current study, we aimed to explore the stigmatisation of eating disorders by comparing the stigma attributed to anorexia nervosa, bulimia nervosa, and binge-eating disorder, utilising depression as a comparative control.
Methods: A total of 235 participants from the general population were randomly assigned to an anorexia nervosa, bulimia nervosa, binge-eating disorder, or depression condition.
