when was dissociative identity disorder added to the dsm
Dissociative identity disorder The DSM-IV-TR states that acts of self-mutilation, impulsivity, and rapid changes in interpersonal relationships "may warrant a concurrent diagnosis of borderline personality disorder".[2] Steven Lynn and colleagues have suggested that the significant overlap between BPD and DID may be a contributing factor to the development of therapy induced DID, in that the suggestion of hidden alters by therapists who propose a diagnosis of DID provides an explanation to patients for the behavioral instability, self-mutilation, unpredictable mood changes and actions they experience.[8] In 1993 a group of researchers reviewed both DID and borderline personality disorder (BPD), concluding that DID was an epiphenomenon of BPD, with no tests or clinical description capable of distinguishing between the two. Their conclusions about the empirical proof of DID were echoed by a second group, who still believed the diagnosis existed, but while the knowledge to date did not justify DID as a separate diagnosis, it also did not disprove its existence.[19] Reviews of medical records and psychological tests indicated that the majority of DID patients could be diagnosed with BPD instead, though about a third could not, suggesting that DID does exist but may be over-diagnosed.[19] Between 50 and 66% of patients also meet the criteria for BPD, and nearly 75% of patients with BPD also meet the criteria for DID, with considerable overlap between the two conditions in terms of personality traits, cognitive and day-to-day functioning, and ratings by clinicians. Both groups also report higher rates of physical and sexual abuse than the general population, and patients with BPD also score highly on measures of dissociation.[7] Even using strict diagnostic criteria, it can be difficult to distinguish between dissociative disorders and BPD (as well as bipolar disorder and schizophrenia),[17] though the presence of comorbid anxiety disorders may help.[29]
Dissociative identity disorder Dissociative identity disorder (DID), also known as multiple personality disorder,[5] is a mental disorder characterized by at least two distinct and relatively enduring personality states.[1] There is often trouble remembering certain events, beyond what would be explained by ordinary forgetfulness.[1] These states alternately show in a person's behavior.[1] Presentations, however, are variable.[3] Associated conditions often include borderline personality disorder, post traumatic stress disorder, depression, substance misuse disorder, self-harm, or anxiety.[1][3]
