Dissociative disorders involve problems with memory, identity, sense of self, perception, emotion, and behavior. Symptoms of a dissociative disorder include the experience of feeling detached from reality, feeling outside one’s body, and a loss of memory or amnesia. Dissociative disorders are frequently associated with previous experiences of trauma.
There are several different diagnostic categories of dissociative disorders. These include:
A person with depersonalization disorder feels persistently or repeatedly detached or estranged from one’s themself. Patients with this condition may report feeling like they are on automatic pilot or as if they are watching themselves in a movie. Similar to this is derealization disorder when a person feels detached from their environment or detached from reality. A person may feel a lack of connection and emotion with the outside world, as if they are dreaming or in a trance.
Temporary experiences of depersonalization and derealization are extremely common in normal populations. In fact, they are the third most commonly reported psychiatric symptoms, after depression and anxiety.
Approximately one-third to one-half of patients with depersonalization disorder report histories of significant trauma. Among accident victims, as many as 60 percent with a life-threatening experience report at least transient depersonalization during the event or immediately after it. Military training studies find that symptoms of depersonalization and derealization are commonly caused by stress and fatigue.
