| Annotation | The relationship between cognitive function and survivorship was examined in a community-dwelling sample from the Seattle Study. Survival analysis was used to examine how level of change in intellectual functioning, verbal memory, perceptual speed, perceived speed, and psychomotor speed were related to mortality in a sample of 601 individuals who subsequently died (mean age 73.81 years), and a control group of 609 survivors of similar ages and levels of education. Those in the lowest 25th percentile of performance had significant risk for subsequent mortality compared to those in the highest 25th percentile. However, after adjusting for demographic variables and psychomotor speed, only perceived speed remained a significant risk factor for mortality. Significant 7-year declines (lowest 25th percentile) in measurements of Verbal Meaning, Spatial Ability, Reasoning Ability, and Psychomotor Speed were risk factors for subsequent mortality relative to those who had least amount of decline. Decrease in cognitive performance tended to be a better predictor of subsequent mortality than was level of cognitive performance. (RH). |
