In the present study, we investigated cognitive status, cognitive development and the effect of mortality on cognitive changes in very old age. Analyzing data from the population-based Heidelberg Centenarian Study, results revealed that centenarians differed quite strongly in their cognitive capacities. While about half of the population showed moderate to severe cognitive impairment, one quarter was found to be cognitively intact. Moreover, analyzing cognitive change over a period of 1.5 years, centenarians' cognitive performance was revealed to be rather stable. Finally, only a small effect of mortality on cognitive status and changes was detected, supporting a recent hypothesis that the terminal decline or drop in cognitive functioning decreases in very old age.
在本研究中，我们调查了高龄老人的认知状况、认知发展以及死亡率对认知变化的影响。通过分析基于人群的海德堡百岁老人研究的数据，结果显示百岁老人的认知能力差异很大。约一半的人群表现出中度至重度认知障碍，而四分之一的人认知功能完好。此外，通过分析1.5年期间的认知变化，发现百岁老人的认知表现相当稳定。最后，仅检测到死亡率对认知状况和变化的微小影响，这支持了最近的一个假设，即高龄老人认知功能的终末期衰退或下降有所减少。
