Abstract

Aim: We describe the association of neurofibromatosis type 1 (NF1) and feeding and eating disorders (FED) in five patients admitted to our third level centre for both FED and NF1.

Methods: Case series of five adolescent females with NF1 treated for FED.

Results: We collected data from five patients with NF1 aged between 14 and 22 years, all females. The onset of eating disorder symptoms occurred between 13 and 19 years of age and was characterised by food intake restriction, associated with physical hyperactivity in three out of five cases. One patient also reported self-injurious acts and episodic binges. Patients received diagnoses of anorexia nervosa (AN, n = 2), atypical AN (n = 1), bulimia nervosa (n = 1), unspecified feeding and eating disorder (n = 1).

Conclusion: The current literature reports a single case of an adult with NF1 and comorbid AN, focusing on the dermatological features of NF1. Our article describes a case series of five patients in developmental age affected by NF1 and FED. Clinical and psychological features of NF1 may play a role in the pathogenesis of FED when these two conditions co-occur. The dermatological alterations of NF1 may contribute to body image distortion that characterises AN. Further research is required to systematically screen populations of patients with NF1 for the presence of FED.

Keywords: anorexia nervosa; bulimia nervosa; children and adolescent; feeding and eating disorder; neurofibromatosis type 1.
