de·lir·i·um (də-lērґe-əm) pl. delirґia [de- + L. lira furrow or track; i.e., “off the track”] [DSM-IV] an acute, transient disturbance of consciousness accompanied by a change in cognition and having a fluctuating course. Characteristics include reduced ability to maintain attention to external stimuli and disorganized thinking as manifested by rambling, irrelevant, or incoherent speech; there may also be a reduced level of consciousness, sensory misperceptions, disturbance of the sleep-wake cycle and level of psychomotor activity, disorientation to time, place, or person, and memory impairment. Delirium may be caused by a number of conditions that result in derangement of cerebral metabolism, including systemic infection, cerebral tumor, poisoning, drug intoxication or withdrawal, seizures or head trauma, and metabolic disturbances such as fluid, electrolyte, or acid-base imbalance, hypoxia, hypoglycemia, or hepatic or renal failure; specific types are named according to etiology, e.g., delirium due to hypoglycemia.
