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.
To reconcile between these theories and to test the link between visual and cognitive decline in mildly cognitive impaired people.
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.
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.
Our results suggest that visual and cognitive abilities decline simultaneously, but they do so independently across visual and cognitive functions and across participants.
最近的研究表明认知和视觉障碍之间存在关联，提出了两种主要理论，即感觉剥夺理论和共同原因理论。大多数研究仅考虑了基本的视觉功能，如视力或视野大小，并评估了与痴呆的关联。
调和这两种理论，并测试轻度认知障碍者的视觉和认知下降之间的联系。
我们对 39 名轻度认知障碍者和 91 名没有任何认知能力下降迹象的老年人进行了 19 项视觉任务测试，测试工具是蒙特利尔认知评估。
我们的研究结果表明，视觉障碍与轻度认知障碍之间存在很强的关联。与以前在年轻和健康老年人中进行的研究结果一致，我们还发现，轻度认知障碍的老年人中，大多数测试之间只有微弱的相关性。
我们的研究结果表明，视觉和认知能力同时下降，但在视觉和认知功能以及参与者之间，它们的下降是独立的。
