Depersonalization: Difference between revisions

In psychiatry, chronic depersonalization that arises during sobriety is identified as "Depersonalization/Derealization Disorder" and is classified by the DSM5 as a dissociative disorder.<ref name=":0" />

Temporary depersonalization symptoms lasting hours to days are common in the general population. Approximately one-half of all adults have experienced at least one episode of this effect within their lifetime, and the gender ratio for the disorder is 1:1.<ref name=":0" /> Chronic depersonalization is more common within individuals who have experienced a severe trauma or prolonged stress and anxiety. The symptoms of both chronic derealization and depersonalization are common within the general population, with a lifetime prevalence of up to 26-74% and 31–66% at the time of a traumatic event.<ref>Hunter, E.

It has also been demonstrated that derealization may be caused by a dysfunction within the brains visual processing center (occipital lobe) or the temporal lobe, which is used for processing the meaning of sensory input, language comprehension, and emotion association.<ref>Sierra, M., Lopera, F., Lambert, M.
