What is Delirium?

Most often occurring in elderly adults, delirium is an impairment of consciousness, marked by a disturbance in attention and awareness. A life-threatening yet potentially reversible disorder of the central nervous system (CNS), delirium often involves perceptual disturbances, abnormal psychomotor activity, ad sleep cycle impairment. The condition develops over a short period of time (usually hours to a few days)and tends to fluctuate in severity during the course of a day. Cognition is also impaired, which can include memory problems, disorientation, language difficulties, or impairment of visuospatial ability and perception. The symptoms are not better explained by another preexisting or evolving neurocognitive disorder. Major causes of delirium include CNS disease (e.g., epilepsy), systemic disease (e.g., cardiac failure), and either intoxication or withdrawal from pharmacological or toxic agents.

 Substance intoxication delirium may be caused by alcohol, cannabis, phencyclidine, opioids, inhalants, sedatives, hypnotics, anxiolytic drugs, amphetamines, cocaine, or other substances.
