Document Summary

During an episode of depersonalization, your perception alters so that you temporarily lose sense of your own reality. The influence of social and cultural factors is strong in dissociative disorders. Onset usually starts after a traumatic life event, after sexual abuse, or after giving birth. Mean age of onset was 16. 1 years and the course tends to be chronic, lasting about. More than 50% of a sample of patients had additional mood and anxiety disorders. More common is localized, or selective, amnesia: a failure to recall specific events, usually traumatic, that occur during a specific period: very common during war. In most cases of dissociative amnesia, the forgetting is very selective for traumatic events of memories rather than generalized. Dissociative amnesia usually occurs in adulthood and it rarely occurs for the first time after the age of 50: prevalence range anywhere between 1. 8 to 7. 3%, suggesting that it is the most prevalent of all dissociative disorders.
