Instead of showing visibly distinct alternate identities, the typical DID patient presents a polysymptomatic mixture of dissociative and posttraumatic stressdisorder (PTSD) symptoms that are embedded in a matrix of ostensibly non-trauma-related symptoms (e.g., depression, panic attacks, substance abuse,somatoform symptoms, eating-disordered symptoms). The prominence of these latter, highly familiar symptoms often leads clinicians to diagnose only these comorbid conditions. When this happens, the undiagnosed DID patient may undergo a long and frequently unsuccessful treatment for these other conditions.- Guidelines for Treating Dissociative Identity Disorder in Adults, Third Revision, p5
