| Annotation | Cognitive functions of centenarians in Japan, Sweden and the United States are described. Definitions and prevalence of dementia are compared between the three countries; levels of cognitive performance between centenarians and younger age groups are presented; and inter-individual variations in cognitive performance in centenarians and younger people are compared for Sweden and the US. Swedish and Japanese studies show a variation in the prevalence of dementia between 40% and 43%, with a relatively higher prevalence in women. Along with the lower cognitive performance in centenarians, the Swedish and US results also show a wider range of performance for centenarians for those semantic or experientially related abilities that tend to be maintained over the adult life span. In contrast, a smaller range of performance is found for centenarians on those fluid or process-related abilities that have shown a downward age-related trajectory of performance. The conclusions agree with the assumption of a general increase in cognitive differentiation with increasing age. (RH). |
