概括

一个新的移动认知自我评估尺度 (CogSAS) 在社区环境中有效地选轻度认知障碍 (MCI) 和阿尔茨海默病 (AD). 这种数字工具具有很高的可靠性和有效性,有助于在不同人群中早期检测.

科学领域:

老年学是一门学科.
神经科学是一个神经科学.
数字健康数字健康

背景情况:

经过验证的移动认知秤用于社区查认知障碍很少.
现有的工具往往面临着社区环境中教育水平较低的挑战.
需要对轻度认知障碍 (MCI) 和阿尔茨海默病 (AD) 的可访问查工具.

研究的目的:

开发和验证一个移动的认知自我评估尺度 (CogSAS) 用于社区查.
为了确保规模对于受限教育的老年人来说是可行的.
评估CogSAS对MCI和AD的诊断准确性.

主要方法:

该CogSAS是使用Delphi过程开发的,包括评估记忆和执行功能的三个任务.
第1阶段涉及518名参与者的项目优化.
第二阶段验证了754名参与者 (认知正常,MCI,痴呆症) 的尺度的可靠性和有效性. 第三阶段测试了83名生物诊断参与者的敏感性和特异性 (MCI/AD导致的痴呆症).

主要成果:

在CogSAS中,表现出良好的内部一致性 (0.81) 和测试复试可靠性 (0.82).
构造有效性为0.74,标准有效性为0.77.
观察到高灵敏度和特异性来区分临床诊断的MCI/痴呆症 (0.90/0.67) 和生物学诊断的MCI/痴呆症由于AD (1.00/0.78) 从认知不受损的个体.

结论:

"CogSAS"是一个可靠,有效和可行的移动尺度用于认知查.
它在社区和临床环境中显示出高灵敏度和特异性.
CogSAS有效地识别了生物诊断的MCI和AD导致的痴呆症.

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Dementia

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....
