It is well recognized that diagnostic assessments and evidence-based treatment approaches developed for anorexia nervosa (AN) or bulimia nervosa (BN) do not apply as well to atypical and complex eating disorders. This chapter provides a description of the evolution of diagnostic criteria for eating disorder presentations that do not fall under the categories of AN and BN. The chapter begins with an overview of atypical and complex comorbid eating disorders, including historical development, diagnostic criteria, and symptom presentation. Following this conceptual overview, the chapter discusses the challenges of applying results from randomized clinical trials for AN or BN to individuals affected by atypical eating disorders or comorbid diagnoses such as anxiety and substance abuse. The chapter concludes by outlining some possible solutions to the conundrum of identifying effective solutions for individuals with atypical and complex comorbid eating disorders.
