Abstract

Introduction: Recent work has shown an association between cognitive and visual impairments and two main theories were advanced, namely the sensory deprivation and the common cause theories. Most studies considered only basic visual functions such as visual acuity or visual field size and evaluated the association with dementia.

Objectives: To reconcile between these theories and to test the link between visual and cognitive decline in mildly cognitive impaired people.

Methods: We employed a battery of 19 visual tasks on 39 older adults with mild cognitive impairment and 91 without any evidence of cognitive decline, as measured by the Montreal Cognitive Assessment.

Results: Our results show a strong association between visual impairment and mild cognitive impairment. In agreement with previous results with younger and healthy older adults, we found also only weak correlations between most tests in older adults with mild cognitive impairment.

Conclusion: Our results suggest that visual and cognitive abilities decline simultaneously, but they do so independently across visual and cognitive functions and across participants.

轻度认知障碍患者视觉能力下降无共同因素。

近年来的研究表明认知障碍与视觉障碍之间存在联系，并提出了两种主要的理论，即感觉剥夺理论和共同原因理论。大多数研究只考虑基本的视觉功能，如视力或视野大小，并评估与痴呆的关系。目的:调和这些理论，并测试轻度认知障碍人群的视觉和认知能力下降之间的联系。方法:我们对39名有轻度认知障碍的老年人和91名没有任何认知衰退迹象的老年人进行了19项视觉任务，这些都是通过蒙特利尔认知评估来测量的。结果:我们的研究结果显示视力障碍和轻度认知障碍之间有很强的联系。与先前对年轻和健康老年人的研究结果一致，我们还发现，在患有轻度认知障碍的老年人中，大多数测试之间的相关性也很弱。结论:我们的研究结果表明，视觉和认知能力是同时下降的，但它们在视觉和认知功能以及参与者之间是独立下降的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
