There is no fixed time because life expectancy depends on age, overall health, and the stage of dementia at admission. Some people live in a care home for a short time after a crisis, while others stay for several years. The average length of stay is typically in the range of 1 to 3 years, though people admitted in the earlier stages of the illness may live there for 4 years or more. Aspiration pneumonia, urinary tract infections, and cardiovascular events are the most common immediate causes of death. The main goal is comfort, safety, and dignity, not a set length of stay.
