According to a review, Delirium, a condition with significant short and long-term effects on cognition and function, should be identified as an indicator of poor long-term prognosis. This helps in prompting immediate and effective management strategies.
"Delirium is extremely common among older adults in intensive care units and is not uncommon in other hospital units and in nursing homes, but too often it's ignored or accepted as inevitable. Delirium significantly increases risk of developing dementia and triples likelihood of death. It can't be ignored," said Regenstrief Institute investigator Babar A. Khan, M.D., M.S., assistant professor of medicine at the Indiana University School of Medicine and an Indiana University Center for Aging Research scientist, the first author of the review.

"As an intensive care unit physician, I have seen that about 80 percent of ICU patients who need mechanical assistance to breathe develop delirium," Dr. Khan said. "That's because in addition to being on a respirator, they have multiple risk factors that can predispose and precipitate delirium, including but not limited to serious illness, restraints and pre-existing cognitive impairment."
