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. Some dissociative disorders are triggered by psychological trauma, but dissociative disorders such as depersonalization/derealization disorder may be preceded only by stress, psychoactive substances, or no identifiable trigger at all.

Some dissociative disorders are triggered by psychological trauma, but dissociative disorders such as 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 Association's DSM-5 are as follows: Both dissociative amnesia and dissociative fugue usually emerge in adulthood and rarely occur after the age of 50. The ICD-10 classifies conversion disorder as a dissociative disorder while the DSM-IV classifies it as a somatoform disorder. Cause: Dissociative identity disorder is caused by ongoing childhood trauma that occurs before the ages of six to nine. People with dissociative identity disorder usually have close relatives who have also had similar experiences. Treatment: Long-term psychotherapy to improve the patients quality of life. Cause: A way to cope with trauma. Treatment: Psychotherapy (e.g. talk therapy) counseling or psychosocial therapy which involves talking about your disorder and related issues with a mental health provider. Psychotherapy often involves hypnosis (help you remember and work through the trauma); creative art therapy (using creative process to help a person who cannot express his or her thoughts); cognitive therapy (talk therapy to identify unhealthy and negative beliefs/behaviors); and medications (antidepressants, anti-anxiety medications or tranquilizers). These medications help control the mental health symptoms associated with the disorders, but there are no medications that specifically treat dissociative disorders. However, the medication Pentothal can sometimes help to restore the memories. The length of an event of dissociative amnesia may be a few minutes or several years. If an episode is associated with a traumatic event, the amnesia may clear up when the person is removed from the traumatic situation. Cause: A stressful event that happens in adulthood. Treatment: Hypnosis is often used to help patient recall true identity and remember events of the past. Psychotherapy is helpful for the person who has traumatic, past events to resolve. Once dissociative fugue is discovered and treated, many people recover quickly. The problem may never happen again.
