概括
大脑粉样血管病变 (CAA) 是一种渐进的疾病,大多数症状和一些症状前患者在一年内显示MRI标记物变化. 大脑微出血 (CMB) 和白质强度 (WMH) 是跟踪试验中短期进展的关键指标.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 遗传学 是一个遗传学.
背景情况:
- 大脑粉样性血管病变 (CAA) 是自发性大脑内分叶出血的重要原因.
- 了解CAA的短期进展对于临床管理和治疗试验设计至关重要.
- 这项研究重点关注疾病的零星 (sCAA) 和荷兰型遗传 (D-CAA) 形式.
研究的目的:
- 调查与CAA相关的各种MRI标志物的1年进展情况.
- 为了比较零星CAA和荷兰型遗传CAA (症状和前症状) 之间的进展模式.
- 确定与CAA进展相关的因素,以及对体损伤和放射性进展之间的关系.
主要方法:
- 有98名参与者的前性队列研究设计.
- 在基线和1年随访期间进行的3T MRI扫描.
- 评估MRI标志物,包括巨型血流,大脑微型血流 (CMB),皮质表面 siderosis (cSS),白质超强度 (WMH) 和BOLD fMRI参数.
主要成果:
- 所有患有sCAA和症状D-CAA的参与者,以及60%的症状前D-CAA,在1年内至少有一种MRI标志物呈现进展.
- 在sCAA和症状D-CAA中,CMB表现出最显著的进展.
- 在非症状的D-CAA中,WMH体积增加最为突出;症状的D-CAA状态与更大的整体进展,CMB和WMH进展有关.
结论:
- 大脑粉样血管病变是一种短时间内的放射性渐进性疾病.
- 在临床试验中,MRI标记物,特别是CMB和WMH体积,对于监测短期CAA进展非常有价值.
- 与其他形式相比,有症状的D-CAA与更具侵略性的疾病进展有关.

Tumor Progression
6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Alzheimer's Disease: Overview
342
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...
