People with dissociative amnesia usually suffer from significant memory loss, often surrounding past and childhood abuse and neglect. It is rare for the patient to lose every memory. Most people with Dissociative Amnesia only have amnesia affecting a specific event or time.
With depersonalization disorder, some patients feel separated from the things happening around them, including their feelings, thoughts, and actions.
People tend to start experiencing symptoms before 16, but it’s possible to encounter the first episode later. However, it is rare for this dissociative disorder to show up after age 20. For those who do experience it, it is a pattern that can repeat throughout their life.
Dissociative Identity Disorder
Previously called multiple personality disorder, DID is described as having two or more different identities. The different identities carry various personalities, behaviors, and memories. People with this diagnosis often have significant trauma in childhood.
