Background: delirium is customary and is associated with many adverse short-term concatenations Objectives: to examine the relationship between an episode of delirium and after dementia and death over 3 years. Design: prospective cohort application of mind Setting: patients (n = 203) were aged 65 years or older at baseline and survivors of the index admission. Methods: Using a standard assessment of cognitive function, we followed 38 inpatients diagnosed with delirium (22 with delirium and dementia, 16 with delirium only) and 148 patients with no delirium or dementia, for a median of 325 month Follow-up was by way of personal interviews, supplemented by standardized clinical examinations. We calculated the incidence and left over s of dementia and the incidence and hazard ratio for death, with adjustment for potential confounder Results: The incidence of dementia was 56% by year over 3 years for those without delirium and 181% by year for those with delirium. The unadjusted relative risk of dementia for those with delirium was 323 (95% confidence interval 186-563) The adjusted relative risk of death also increased (180; 111- 292) while the median survival time was significantly shorter in those with (510 days; 433-587) than in those without delirium (1122 days; 922-1322) Conclusion: delirium appears to be an important marker of risk for dementia and death, unruffled in older people without prior cognitive or functional impairment.
