慢性失眠和认知障碍是老年人的常见症状。这项研究探讨了老年人慢性失眠与认知功能变化之间的关联。研究人群包括两组：64 名没有失眠症的老年人和 35 名患有失眠症的老年人。每个参与者的认知能力在参与者的家中使用计算机化的“MindFit”测试（CogniFit，Inc.）进行测试。在五个类别的认知功能中，与睡眠良好的老年人相比，失眠的老年人表现出较差的表现。具体来说，失眠症患者和睡眠良好的人在记忆广度、目标注意力分配、时间估计、执行功能以及二维（视觉和语义）测试的整合方面存在显着差异。研究结果表明，失眠可能会对健康老年人的某些认知功能产生不利影响。
Chronic insomnia and cognitive impairment are both common complaints among older adults. This study explores the association between chronic insomnia and changes in cognitive functioning among older adults. The study population comprised two groups: 64 older adults without insomnia and 35 older adult insomniacs. The cognitive capacity of each participant was tested at the participant's home using the computerized "MindFit" test (CogniFit, Inc.). In five categories of cognitive functioning, older adult insomniacs displayed impaired performance compared to older adult good sleepers. Specifically, significant differences were found between insomniacs and good sleepers on memory span, allocating attention to a target, time estimation, executive functioning, and integration of two dimensions (visual and semantic) tests. The findings imply that insomnia may have detrimental effects on some cognitive functions in healthy older adults.
