Abstract

A sample of 33 young-old (ages 65 to 74) and 20 oldest-old (ages 84 to 93) healthy elderly without dementia were assessed with neuropsychological tests annually over a 4-year period to examine longitudinal changes in cognitive functioning. Significant age-group differences existed at baseline in participants' performances on tests of immediate memory and visuospatial skills. There were no age-group differences in the rate of change over the 4-year interval on any neuropsychological tests. Within each age-group, the amount of change over time was minimal for most tests though some practice effects were apparent, and on some tests mild decline was observed. Results suggest that healthy old adults, including the oldest-old, do not experience measurable declines in cognitive functioning over a 4-year period.
