Part II - Clinical Description of Orthorexia Nervosa

Summary

Part II presents the definition of orthorexia nervosa and a proposal of its new definition (‘Salussitomania’) due to the inaccurate etymology of the term Orthorexia Nervosa. It includes diagnostic criteria sets for orthorexia nervosa (proposed by Setnick, 2013; Moroze et al., 2015; Barthels et al., 2015; Dunn and Bratman, 2016) to depict key features of orthorexia nervosa, global study distribution on orthorexia nervosa as well as the divergence and overlap of orthorexia nervosa and other mental disorders, namely anorexia nervosa, obsessive-compulsive disorder and avoidant/restrictive food intake disorder, to enable a differential diagnosis. A summation of the highlights is included at the end of this chapter. The commentaries of the invited international experts (Dr Caterina Novara, University of Padova, Italy and Dr Hana Zickgraf, Rogers Behavioral Health, USA) provide valuable insights on orthorexia nervosa.
