概括
不完整的威利斯循环 (CoW) 与健康老年人的认知能力下降有关. 缺少两个或两个以上的Cow血管独立地预测认知障碍,这表明Cow变异是危险因素.
科学领域:
- 神经学 神经学
- 神经科学是一个神经科学.
- 公共卫生 公共卫生
背景情况:
- 不完整的威利斯循环 (CoW) 与缺血性中风的严重程度和预后有关.
- 在健康成年人中,Cow变异的临床意义尚不清楚.
- 这项研究调查了不完整的Cow和社区居住的老年人的认知衰退之间的联系.
研究的目的:
- 检查威利斯圆的变化与认知衰退之间的关联.
- 确定不完整的Cow是否是明显健康的老年人认知障碍的独立风险因素.
主要方法:
- 对829名50岁及以上的社区成年人进行横截面研究.
- 磁共振成像 (MRI) 评估了Cow变异和大脑小血管疾病 (Fazekas尺度).
- 认知功能使用基于计算机的问卷进行评估.
主要成果:
- 与完整的Cow (5.7%) 相比,缺少Cow血管的人 (缺少1个血管:9.0%;缺少≥2个血管:12.2%) 的认知障碍更为普遍.
- 即使考虑到白质病变和常规风险因素,不完整的Cow和认知障碍之间的关联仍然很重要.

The Arch of Aorta
508
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Language and Cognition
302
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Alzheimer's Disease: Overview
405
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...
