""The Diagnostic and Statistical Manual of Mental Disorders (DSM) is a publication of the American Psychiatric Association, and is written with input from a large number of clinical experts-not just psychiatrists-in different specialty areas related to mental health. The DSM describes the signs and symptoms of all psychiatric conditions, and provides criteria to guide treatment providers in deciding whether an individual has a recognized mental disorder. The DSM has been in use since 1952, and the current, fifth edition, DSM-5, was published in 2013. Each revision to the DSM has been aimed at improving the usefulness of the manual. Eating disorders are considered psychiatric illnesses and are therefore listed in DSM-5. Eating disorders are listed in a section called Feeding and Eating Disorders. But, as a shorthand, we are going to refer to all the disorders in this section of DSM-5 as eating disorders. The diagnostic criteria for eating disorders in DSM-5 are different from what came before, in DSM-IV; in the DSM-5, changes were made that aimed to clarify some items, and to make the criteria relevant to all groups of patients (for example, adolescents as well as adults, males as well as females).
