Mortality of the Aged with Chronic Brain Syndrome

ABSTRACT: The five‐year survival rates for a group of aged persons in a home and hospital for the aged showed that those with chronic brain syndrome (CBS) died at a much higher rate than those without CBS. Bronchopneumonia predominated as the cause of death among those with CBS but not among those without CBS. The mortality for 145 subjects was computed by relating the actual number of deaths to the expected (life tables) number of deaths as a function of age and sex of residents in the same institution. Differences, on the basis of presence or absence of CBS, were statistically significant for females irrespective of whether they were in relatively poor, or relatively good physical condition.
