title: Deconstructing "Atypical" Eating Disorders: an Overview of Emerging Eating Disorder Phenotypes.
abstract: Recent changes to the diagnostic framework of eating disorders (ED's) in DSM-5 were introduced to reduce the large preponderance of cases falling within the residual and undifferentiated category. However, current reports continue to illustrate overrepresentation of cases in this residual category, suggesting that clinical reality comprises more diverse ED psychopathology than is accounted for in the current diagnostic spectrum. However, with emerging evidence preliminarily delineating several additional distinct phenotypes, we aim to provide a narrative overview of emerging ED phenotypes which (i) are not currently located as a specific diagnostic category in diagnostic criteria for ED's, (ii) centrally feature ED psychopathology, and (iii) have emerging empirical evidence suggesting the distinct nature of the syndrome. A greater awareness of these emerging phenotypes will likely facilitate accurate diagnostic practice and may also serve to facilitate further empirical efforts.
