Recent research has focused on clarifying the neurological basis of symptoms associated with dissociation by studying neurochemical, functional and structural brain abnormalities that can result from childhood trauma. Others in the field have argued that recognizing disorganized attachment (DA) in children can help alert clinicians to the possibility of dissociative disorders. In their 2008 article, Rebecca Seligman and Laurence Kirmayer suggest the existence of evidence of linkages between trauma experienced in childhood and the capacity for dissociation or depersonalisation. They also suggest that individuals who are able to utilise dissociative techniques are able to keep this as an extended strategy to cope with stressful situations.Clinicians and researchers stress the importance of using a developmental model to understand both symptoms and the future course of DDs. In other words, symptoms of dissociation may manifest differently at different stages of child and adolescent development and individuals may be more or less susceptible to developing dissociative symptoms at different ages. Further research into the manifestation of dissociative symptoms and vulnerability throughout development is needed. Related to this developmental approach, more research is required to establish whether a young patients recovery will remain stable over time. Current debates and the DSM-5
A number of controversies surround DD in adults as well as children. First, there is ongoing debate surrounding the etiology of dissociative identity disorder (DID). The crux of this debate is if DID is the result of childhood trauma and disorganized attachment.
Dissociative disorders (DD) are conditions that involve disruptions or breakdowns of memory, awareness, identity, or perception. People with dissociative disorders use dissociation as a defense mechanism, pathologically and involuntarily. The individual experiences these dissociations to protect themselves. Some dissociative disorders are triggered by psychological trauma, but depersonalization-derealization disorder may be preceded only by stress, psychoactive substances, or no identifiable trigger at all.The dissociative disorders listed in the American Psychiatric Associations DSM-5 are as follows:
Dissociative identity disorder (formerly multiple personality disorder): the alternation of two or more distinct personality states with impaired recall among personality states. In extreme cases, the host personality is unaware of the other, alternating personalities; however, the alternate personalities can be aware of all the existing personalities. Dissociative amnesia (formerly psychogenic amnesia): the temporary loss of recall memory, specifically episodic memory, due to a traumatic or stressful event. It is considered the most common dissociative disorder amongst those documented. This disorder can occur abruptly or gradually and may last minutes to years depending on the severity of the trauma and the patient. Dissociative fugue was previously a separate category but is now treated as a specifier for dissociative amnesia. Depersonalization-derealization disorder: periods of detachment from self or surrounding which may be experienced as "unreal" (lacking in control of or "outside" self) while retaining awareness that this is only a feeling and not a reality. The old category of dissociative disorder not otherwise specified is now split into two: other specified dissociative disorder, and unspecified dissociative disorder.
