DELIRIUM IS DEFINED as a "mental disturbance" marked by disorientation and confused thinking in which the patient incorrectly interprets his/her surroundings. The Diagnostic and Statistical Manual of Mental Disorders (DSM) IV criteria 1 Diagnostic and Statistical Manual of Mental Disorders (DSM) IVAmerican Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. American Psychiatric Association, Washington: DC2000 Google Scholar include "disturbance of consciousness such as reduced clarity or awareness of the environment with reduced ability to focus, sustain, or shift attention; a change in cognition or the development of a perceptual disturbance that is not better accounted by a preexisting, established, or evolving dementia; development of the disturbance over a short period of time (usually hours to days) with a tendency to fluctuate during the course of the day; and evidence from the history, physical examination, or laboratory findings that the disturbance is caused by the direct physiologic consequences of a general medical condition." 1 Diagnostic and Statistical Manual of Mental Disorders (DSM) IVAmerican Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision.
