Background:
Anorexia Nervosa (AN) poses significant therapeutic challenges, especially in cases meeting the criteria for Severe and Enduring Anorexia Nervosa (SE-AN). This subset of AN is associated with severe medical complications, frequent use of services, and the highest mortality rate among psychiatric disorders.
Case Presentation:
In the present case series, 14 patients were selected from those currently or previously taken care of at the Eating Disorders Outpatients Unit of the Maggiore Hospital in Bologna between January 2012 and May 2023. This case series focuses on the effects of the disease, the treatment compliance, and the description of those variables that could help understand the great complexity of the disorder.
Conclusion:
This case series highlights the relevant issue of resistance to treatment, as well as medical and psychological complications that mark the life course of SE-AN patients. The chronicity of these disorders is determined by the overlapping of the disorder's ego-syntonic nature, the health system's difficulty in recognizing the problem in its early stages, and the presence of occupational and social impairment.
