Treatment recommendations and predictors in Eating Disorders

Abstract Eating disorders are severe mental disorders with a high mortality rate - suicidality - and a high incidence in adolescence and early adulthood, especially in women. The course of these disorders is uncertain and treatment outcomes are limited, with successful outcomes in 50-75% of cases. For bulimia nervosa (BN) and binge eating disorder (BED), several factors, such as duration of the disorder, eating and general psychopathology, dysfunctional personality traits and cognitive impairment, have been found to be associated with treatment adherence and response. In anorexia nervosa (AN) and atypical ED (OSFED), treatment response is poorer, with higher dropout rates and longer duration and chronicity. In this presentation, we will describe recent prospective observational studies in large samples of EDs analysing clinical, personality and cognitive predictors of treatment response in eating disorders, as well as potential associated neurobiomarkers. Optimisation of health care resources and transitions, as well as early and effective personalised treatments, can change the trajectory of EDs. Disclosure of Interest F.
