Overview
History
Duration
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 times symptoms resolve by 10to 12 days;
- Up to 15% of patients, typically elderly, symptoms of delirium may last for a month and beyond.
Prognosis==
- Majority of patients have complete recovery
- If untreated delirium may progress to stupor, coma, seizures, or death.
- Delirium in AIDS patients has a poorer prognosis, 27% tends to have complete recovery of cognitive faculties, this may be because of underlying AIDS dementia.
- Delirium in an elderly, can cause many complications, which may include pneumonia and decubitus ulcers, prolonging hospital stays.
- Elderly:
- Only 4% to 40% may have complete recovery
- Persistent cognitive deficits are common while recovering from delirium, may be related previously unknown aliments.
- 22%–76% chance of dying during hospitalization if delirium is developed during respective hospital stay and a very high death rate during the months following discharge.
- Up to 25% of patients with delirium die within 6 months and that their mortality rate in the 3 months after diagnosis is 14 times as high as the mortality rate for patients with affective disorders.
- If delirium develops after orthopedic surgery, risk for postoperative complications increases: longer postoperative recuperation periods, longer hospital stays, and long-term disability.[1]
