The lifetime prevalence of anorexia is 1.4% in women and 0.2% in men. Ultimately, only half of people treated for anorexia nervosa in adolescence recover, 30% simply improve, 21% suffer from chronic disorders and 5 to 6% die. At the same time, between a quarter and half of patients abandon their current treatment, including during hospitalization. Relapses occur during the evolution of anorexia nervosa. Even more worrying, mortality is highest the year following the patient's discharge from hospital. This appears to be due to somatic complications in more than half of cases (most often cardiac arrest), to suicide in 27% of cases. Researchers are still trying to clarify the mechanisms involved in the emergence and persistence of this disorder. The objective is to obtain more verified and faster cures. However, the obstacles to successful treatment are mainly due to the denial of disorders and thinness. From a neurocognitive perspective, the representation one has of one's body is underpinned by two types of representations, i.e. body image and body schema.
