概括
像p-tau217这样的等离子体生物标志物显示出大脑中检测异常的粉样β和tau的潜力. 神经纤维光 (NfL) 可能表明神经退行,有助于在社区环境中早期发现疾病.
科学领域:
- 神经学 神经学
- 生物标志物发现发现
- 神经成像是一种神经成像.
背景情况:
- 在诊断阿尔茨海默病时,ATN (β-粉样蛋白,,神经退行) 框架至关重要.
- 在不同人群中评估这些生物标志物对于公平的医疗保健至关重要.
研究的目的:
- 评估血生物标志物以识别异常的粉样β (Aβ) 定子发射断层扫描 (PET),tau-PET和神经退行.
- 通过使用ATN框架在社会经济上处于不利地位的基于人口的队列中评估这些生物标志物.
主要方法:
- 113名没有痴呆症的参与者 (102名认知正常) 接受了ATN神经影像和血生物标志物分析.

01:26Alzheimer's Disease: Overview
669
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 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.
