作为痴呆症研究的一部分，162名年龄在65-84岁之间的正常志愿者接受了一系列9项神经心理学测试，评估时间定向、短期记忆、语言功能和视觉感知能力。与年龄小于65岁的受试者相比，该组在80岁之前几乎没有表现出认知功能全面下降的证据。80-84岁的亚组在测试中显示出比年轻亚组更高的总体失败率。然而，80-84岁亚组中70%的受试者在9次测试中失败不超过1次。在对老化影响的敏感性方面，这些测试之间存在实质性差异。短期视觉记忆、连续数字学习和面部识别测试中表现下降幅度最大。其他语言、记忆和视觉感知测试在80岁时仍表现良好。这些发现为正常衰老不一定涉及认知功能水平的普遍下降这一假设提供了有限的支持。被认为是敏感或不敏感的老化的影响测试的临床应用。
As part of a study of dementia, 162 normal human volunteers in the age range of 65-84 yr were given a battery of 9 neuropsychological tests assessing temporal orientation, short-term memory, language functions and visuoperceptive capacity. When compared to subjects less than 65 yr of age, the group showed little evidence of generalized decline in cognitive function before the age of 80 yr. The 80-84 yr subgroup showed a higher overall failure rate on the tests than the younger subgroups. Nevertheless, 70% of the subjects in the 80-84 yr subgroup made no more than 1 failure on the 9 tests. There were substantial differences among the tests in respect to their sensitivity to the effects of aging. The largest decline in performance was shown on tests of short-term visual memory, serial digit learning and facial recognition. The other verbal, memory and visuoperceptive tests were performed well up to the age of 80 yr. The findings provide limited support for the hypothesis that normal aging does not necessarily involve a general decline in the level of cognitive functioning. The clinical application of the tests that were sensitive or insensitive to the effects of aging is considered.
