dementia was also found in 70% of delirious
patients. Mean age of patients with dementia was
85 years, but 81 years with delirium. The mortality
rate of delirious patients was 32% and the main
causes of delirium was congestive cardiac failure
(27%) and severe infections (30%). The mortality
rate for dementia alone was 8%.
Cognitive dysfunction is common among acute
medical elderly patients and special emphasis of
care will be needed for patients in delirious states.
