==Overview==
History, complication of delirium and prognosis depends for many factors such as, etiology, risk factors, and co-morbid illness.
The duration of [[delirium]] may vary from hours to months. After remission , [[delirium]] may increase the risk of functional decline, [[cognitive dysfunction]], and [[institutional placement]], and with higher [[mortality]]. [[Delirium]] in the elderly, can cause many complications, which may include [[pneumonia]] and [[decubitus ulcers]], prolonging [[hospital]] stays. [[Delirium]] was associated with longer postoperative recovery periods, longer hospital stays, and long-term disability after [[orthopedic]] surgery. Common complications associated with  [[delirium]] include increased [[mortality]], [[cognitive impairment]], longer durations of [[mechanical ventilation]], longer lengths of stay in the [[ICU]]. Prognosis is  dependent on the severity of [[delirium]], and the 1 year [[mortality rate]] of [[patients]] with [[delirium]] is approximately 10%-26%.

Overview

The duration of delirium may vary from hours to months. After remission , delirium may increase the risk of functional decline, cognitive dysfunction, and institutional placement, and with higher mortality. Delirium in the elderly, can cause many complications, which may include pneumonia and decubitus ulcers, prolonging hospital stays. Delirium was associated with longer postoperative recovery periods, longer hospital stays, and long-term disability after orthopedic surgery. Common complications associated with delirium include increased mortality, cognitive impairment, longer durations of mechanical ventilation, longer lengths of stay in the ICU. Prognosis is dependent on the severity of delirium, and the 1 year mortality rate of patients with delirium is approximately 10%-26%.

History

  • The duration of delirium is typically affected by the underlying cause.
  • If caused by a fever, the delirious state often subsides as the severity of the fever subsides.
  • Ranges from less than a week to more than 2 months.
  • Most of the time symptoms resolve by 10 to 12 days.
  • Up to 15% of patients, typically elderly, delirium may last for a month and beyond.
  • Delirium associated with substance withdrawal develops when concentrations of the substance in fluid and tissue decrease.
