Dissociative disorders are dysfunctions that cause a disruption in memory, perception, identity, awareness, etc. of a person. These disorders are also called derealization, a change made in DSM-5. Additionally, another change for Dissociative Disorders in DSM-5 is that dissociative amnesia and dissociative fugue are now not considered separate in the diagnosis, but dissociative fugue it is a characteristic of dissociative amnesia. Dissociative amnesia is the inability to remember important personal information (Barlow and Durand 2009). Dissociative Escape is the unexpected trip away from home or usual place of work (Barlow & Durand, 2011). Thesis Statement: Dissociative disorders come in many forms, but the focus will be on dissociative identity disorder and Shirley Ardell Mason (also known as Sybil), highlighting her sixteen personalities. According to the Cleveland Clinic, "Dissociative disorders are mental illnesses that involve disruptions or breakdowns in memory, awareness, identity, and/or perception. When one or more of these functions are disrupted, symptoms may occur. These symptoms can interfere with a person's overall functioning, including social activities, work functions, and relationships." 'have multiple personalities. Furthermore, dissociative traits occurred in a person diagnosed with multiple personality disorder, so the name change was necessary ), they make a transition with the original personality (the patient's personality). The original personality is, in... middle of the paper... beyond the traumatic events. Shirley Mason's treatment was therapy with her psychoanalysts. One of her personalities attempted suicide and as a result her doctor prescribed sodium pentothal for her anxiety. Eventually, four of Shirley's personalities merged and formed a new, cured Shirley, and the others either died out or integrated with Shirley. Eventually, he regained a unique identity with the traits of his old sub-personalities and was finally able to live a normal life. DID is a serious disorder, due to the extremes and lack of control one can experience. Although the etiology is not completely agreed upon, it is safe to assume that this disorder results from some traumatic experience. There is no guarantee that a person will ever fully recover, but it is optimistic to understand that the possibility of full integration exists.
