Abstract:
A 19-year-old female patient with anorexia nervosa developed profound weight loss over 1 year associated with vegetarianism and excessive exercise. There was severe wasting and proximal muscle weakness in the legs and bilateral weakness of eye closure. A purpuric rash developed due to vitamin C deficiency. This case demonstrates a new neurological sign in anorexia nervosa indicating a weakness of the orbicularis oculi muscles as part of a more general myopathy. The myopathic and scorbutic features may have a common pathogenesis.
