概括

血p-tau217准确地预测了在没有认知障碍的个体中轻度认知障碍 (MCI) 的进展. 升高的水平表明未来的认知能力下降,即使与其他生物标志物相结合.

科学领域:

神经科学是一个神经科学.
生物标志物研究生物标志物研究
认知老龄化认知老龄化

背景情况:

评估血p-tau217的预后准确性,以预测在认知不受损 (CU) 个体中轻度认知障碍 (MCI) 的进展.
血采集后的长期随访 (平均5.65年).

研究的目的:

评估血p-tau217作为认知能力下降的预后标志物.
将血p-tau217与CSF和PET生物标志物进行比较,用于MCI预测.

主要方法:

包括215名血Aβ42/40和p-tau217.7的参与者.
在子集中使用了CSF和PET成像 (18F-NAV4694,18F-flortaucipir).
根据专家的共识确定MCI进展,对生物标志物数据视而不见.

主要成果:

与A-T血相比,在血p-tau217 (A+T+血,A-T+血) 升高的个体中观察到较高的MCI进展率.
在CSF和PET的生物标志物中发现了类似的预后准确性.
血Aβ42/40并没有提高MCI的p-tau217预测准确性.

结论:

血p-tau217是一种可靠的预后标志物,可用于识别10年内患有认知障碍风险的个体.
在CU个体中血p-tau217升高意味着未来的临床进展.
在时间元ROI中异常的tau PET在所有病例中都预测了MCI进展.

关键词:

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...

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....

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,...
