术语“轻度认知障碍”是指超过正常生理老化过程但不满足痴呆标准的认知缺陷。虽然最近的研究表明，各自的缺陷可以可靠地评估，不同的诊断标准，阻止了广泛的应用，这种诊断在临床实践中。本研究的目的是（1）评估四个当前诊断概念的患病率和（2）调查轻度认知障碍的心理和社会人口学变量。分析了从成人发育跨学科纵向研究中招募的202名先证者的数据。检查时，先证者年龄在60 - 64岁之间，身体健康。确定了以下患病率：年龄相关性记忆障碍（AAMI）为13.5%，年龄一致性记忆障碍（ACMI）为6.5%，晚年健忘（LLF）为1.5%，年龄相关性认知下降（AACD）为23.5%。认知缺陷的投诉与抑郁和神经质量表的较高分数显着相关，但与神经心理学指标无关。在神经心理测试中表现不佳与较低的教育水平和社会经济地位有关。我们的结论是轻度认知功能障碍的患病率在很大程度上取决于所应用的诊断标准。在这方面，自我报告的认知能力下降可能是一个不太有用的标准。纵向研究是必要的，以进一步阐明这些诊断标准的预测价值。
The term "mild cognitive impairment" refers to cognitive deficits which exceed normal physiological aging processes, but do not fulfill the criteria for dementia. While recent studies indicate that the respective deficits can be reliably assessed, different diagnostic criteria have prevented a wide application of this diagnosis in clinical practice. The aims of the present study were (1) to assess the prevalence rates of four current diagnostic concepts and (2) to investigate mild cognitive impairment with respect to psychological and sociodemographic variables. Data from 202 probands recruited from the interdisciplinary longitudinal study on adult development were analyzed. On the time of examination, probands were between 60 to 64 years old and in a good health. The following prevalence rates were determined: 13.5% for age-associated memory impairment (AAMI), 6.5% for age-consistent memory impairment (ACMI), 1.5% for late-life forgetfulness (LLF), and 23.5% for aging-associated cognitive decline (AACD). Complaints of cognitive deficits were significantly correlated with higher scores on depression and neuroticism scales but with none of the neuropsychological measures. Reduced performance in neuropsychological tests was associated with a lower educational level and socioeconomic status. We conclude that the prevalence rates of mild cognitive impairment are highly dependent on the diagnostic criteria applied. In this respect the self-report of cognitive decline might be a less useful criteria. Longitudinal studies are warranted to further elucidate the predictive value of these diagnostic criteria.
