We examined the relation of level of cognition to survival in a biracial community population of more than 10,000 older persons. At baseline, participants completed 4 cognitive tests from which a composite global cognitive measure was derived. During up to 14 years of follow-up (mean = 6.9 years), 4201 people died (41.6%). Higher level of cognitive function was associated with increased survival even after controlling for health related and lifestyle variables. The association did not differ between African Americans and whites; it was stronger in older than younger persons; and it was especially pronounced for perceptual speed. The results underscore the importance of cognition to survival in old age. (Contains 2 tables and 2 figures.)
