Discusses the recent deletion of the term "organic" from Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) in order to help emphasize that the neurobiological underpinnings of psychiatric disorders. Thus, in DSM-IV the major diagnostic categories include a diagnostic entity where the phrase "due to a general medical disorder" is used (e.g., psychotic disorder due to a general medical disorder and mood disorder due to a general medical disorder). Furthermore, there is a category "Mental Disorders Due to a General Medical Condition," which includes the diagnosis of "Mental Disorder Not Otherwise Specified Due to a General Medical Disorder." The authors argue that at least some additional conditions are sufficiently important to deserve their own specific term. In particular, the misdiagnosis of a general medical disorder with eating symptoms as anorexia nervosa may have grave consequences. The authors argue that the availability of a diagnostic entity such as "Eating Disorder Due to a General Medical Condition" would help clinicians to appreciate an important differential diagnosis in patients with eating disorder symptoms. Similar considerations would apply in the sections of paraphilia, impulse control disorder, and dissociative symptoms
