ICU Stay Doubles Dementia Risk
ICU hospitalization doubled the risk of subsequent dementia in older adults, a longitudinal study showed. Researchers studied 3,822 older adults in five diverse epidemiologic cohorts at the Rush Alzheimer's Disease Center without known dementia at enrollment. Compared with similar people who didn't have an ICU stay, older adults who had an ICU experience were more likely to develop all-type dementia or Alzheimer's dementia. Critical illness itself may harm the brain in some cases, researchers noted; for other patients, ICU events like sedation, severe sepsis, or acute dialysis may be contributing factors.
