depersonalization

 [de-per″sun-al-ĭ-za´shun]
alteration in the perception of the self so that the usual sense of one's own reality is lost, manifested in a sense of unreality or self-estrangement, in changes of body image, or in a feeling that one does not control one's own actions and speech; seen in disorders such as depersonalization disorder (see also dissociative disorders), depression, hypochondriasis, temporal lobe epilepsy, schizophrenia, and schizotypal personality disorder. Some authorities do not draw a distinction between this concept and derealization, and use the term depersonalization to include both.
depersonalization disorder a dissociative disorder in which there are feelings of unreality and strangeness in one's perception of self or of one's body image. Individuals with this disorder may feel as though they are in a dream or are not totally in control of their actions. Episodes of depersonalization are usually accompanied by dizziness, anxiety, fears of going insane, and derealization.

Depersonalization as an isolated event occurs in many people without significantly affecting their functioning; it is considered a disorder only when it impairs the patient's daily activities, when it is not associated with some other mental disorder, and when the patient's perception of reality remains intact.
