Dissociative Identity Disorder
When a person goes through an overwhelmingly traumatic experience, it is common to dissociate from it if it is too distressing to remember. For example, physical or sexual abuse might trigger detachment, the same way that going through an event such as the recent mass shooting at the Las Vegas concert may cause a survivor to “blank out” the memory that is causing emotional pain. For some individuals, however, their distress is so severe they may not be able to connect with their memories, feelings or even to their own sense of identity. These people likely have Dissociative Identity Disorder.
