During the depersonalization or derealization experience, reality testing remains intactĬ. Derealization: Persistent or recurrent experiences of unreality of surroundings (e.g., world around the person is experienced as unreal, dreamlike, distant, or distorted)ī.
Depersonalization: Persistent or recurrent experiences of feeling detached from, and as if one is an outside observer of, one’s mental processes or body (e.g., feeling as though one is in a dream sense of unreality of self or body or time moving slowly)Ī2. Also, it is thought that trauma and childhood abuse (physical, emotional, and/or sexual) could be a factor to depersonalization disorder.Ī1. Individualism is stressed in most Western cultures and may have an effect on an individual’s sense of self. Western cultures where individuals live in a more individualistic society may be more likely to suffer from a depersonalization disorder. Lower levels of nerve cell responses in the area of the brain that controls emotion may correlate to the emotional detachment that individual’s feel during an episode of depersonalization. The sensory cortex controls the senses and perception of an individual’s body in space. Positron emission tomography scans used to assess brain glucose metabolism show abnormalities in the sensory cortex including the temporal, occipital, and parietal lobes.
Brain imaging including pet scans show sensory cortex abnormalities. Similar to the other dissociative disorders, scientists link severe childhood abuse to depersonalization disorders. Gender and cultural differences in presentation.
