Objective Research evidence suggests the need to identify treatments based on a more precise characterization of psychopathology and psychiatric comorbidity in anorexia nervosa. Network analysis provides a new method to conceptualize psychopathology. We use this approach to investigate the relationships between eating disorder and general psychiatric symptoms in adolescents with anorexia nervosa. Methods Four‐hundred and five adolescents with anorexia nervosa and illness duration less than 3 years were consecutively recruited from those admitted to inpatient treatment. They completed the following questionnaires: the Eating Disorder Inventory‐3, the Multidimensional Anxiety Scale for Children, the Children's Depression Inventory, and the Youth Self Report. A network analysis was conducted, including eating psychopathology measures, anxiety and depressive symptoms, and obsessive–compulsive and post‐traumatic stress problems. We employ a novel approach, the bridge function, to identify symptom clusters. Results Depression symptoms and personal alienation were the nodes with the highest centrality in the network, followed by asceticism, post‐traumatic stress problems, drive to thinness, low self‐esteem, and anxiety physical symptoms. Three symptom clusters (relative to eating disorder psychopathology, self‐esteem problems, and internalizing difficulties) were identified. Depression symptoms, personal alienation, low self‐esteem, and interoceptive deficits showed the highest bridge centrality. Besides eating disorder core symptoms, negative affect and internalizing symptoms seem to contribute to anorexia nervosa psychopathology independently from illness duration effects. Discussion These findings suggest that anorexia nervosa is characterized by a broad psychopathological spectrum rather than the mere eating disorder core symptoms, confirm the need to re‐conceptualize psychiatric comorbidity in this disorder, and provide intriguing diagnostic and therapeutic implications.

Poor treatment outcomes are available for anorexia nervosa (AN) and treatment innovations are urgently needed. Recently, non-invasive neuromodulation tools have suggested to have potential for reducing an symptomatology targeting brain alterations. The objective of the study was to verify whether left anodal/right cathodal prefrontal cortex transcranial direct current stimulation (tDCS), may aid in altering/resetting inter-hemispheric balance in patients with AN, re-establishing control over eating behaviors. Twenty-three adolescents with an underwent a treatment as usual (AU), including nutritional, pharmacological, and psychoeducational treatment, plus 18 sessions of tDCS (TDCS+AU = n11; mean age = 13.9, SD = 1.8 years) or a family based therapy (FBT+AU = n12, mean age = 15.1, SD = 1.5 years). Psychopathological scales and the body mass index (BMI) were assessed before and after treatment. After 6 weeks of treatment, the BMI values increased only in the tDCS group, even at 1-month follow-up. Independently of the treatment, all participants improved in several psychopathological measures, included AN psychopathology and mood and anxiety symptoms. Our results demonstrated for the first time a specific effect of the left anodal/right cathodal tDCS treatment protocol on stable weight gain and a superiority compared to an active control treatment for adolescents with AN. Results were interpreted as a possible direct/indirect effect of tDCS in into some pathophysiological mechanisms of AN, involving the mesocortical dopaminergic pathways and the promotion of food intake. This pilot study opens new perspectives in the treatment of an in adolescence, supporting the targeted and beneficial effects of a brain-based treatment.

This study aimed to examine the presence of Autism Spectrum Disorder (ASD) in a sample of female adolescents with Anorexia Nervosa (AN) during the acute phase of illness. We also compare the level of autistic traits, social perception skills and obsessive-compulsive symptoms in four groups: AN, ASD, and two gender- and age-matched control groups. Of the 30 AN participants, only three scored above the conventional ADOS-2 threshold for ASD. The AN participants were similar to their controls on autistic trait measures, and to the ASD group on obsessive-compulsive measures, and on theory of mind ability and affect recognition measures. Further longitudinal studies are needed in order to determine the association between these conditions.

This study aims at examining whether adolescent girls diagnosed with anorexia nervosa and their parents differ in perceiving the different aspects of family functioning. Moreover, the discrepancy between adolescent girls and healthy controls on Family Adaptability and Cohesion Evaluation Scales dimensions, family communication, and family satisfaction is investigated. The study includes 36 female anorexia patients and their parents and 36 healthy controls. The results showed a different view between mothers and their daughters with regard to the dimension of rigidity. In addition, girls with anorexia nervosa were less satisfied about family environment and rated their families as less communicative, flexible, cohesive, and more disengaged, compared to controls.
