概括
创致性脑粉样蛋白血管病变 (iCAA) 可能是神经外科手术的结果,可能是由于β-粉样蛋白种子的子传播. 在年轻患者中早期怀疑ICH和神经外科病史对于诊断和管理至关重要.
科学领域:
- 神经学 神经学
- 神经外科 神经外科
- 病理学 病理学 病理学
背景情况:
- 阴性脑粉样血管病变 (iCAA) 是一种与神经外科手术相关的新兴病理.
- 在手术期间,β-粉样蛋白种子的子传递是iCAA开发的拟议机制.
- 大多数报告的iCAA病例的预后不佳,复发性脑内出血 (ICH) 和死亡率高.
研究的目的:
- 为了说明神经外科干预导致的iCAA病例.
- 突出类β-粉样转移在iCAA中的潜在作用.
- 强调早期识别和诊断iCAA在风险患者中的重要性.
主要方法:
- 在神经外科手术后,对疑似iCAA患者的病例报告分析.
- 利用成像研究,包括PET-CT扫描检测β-粉样蛋白.
- 使用脑脊液 (CSF) 分析来确定β-粉样蛋白积累.
主要成果:
- 在有神经外科干预史的患者中出现了两例iCAA.
- 案例1:在儿童神经外科手术后被诊断为iCAA,在PET-CT上显示β-粉样沉积物,在2年的随访后恢复良好 (mRS 1).
- 案例2:在阿诺德-奇亚里形手术后被诊断出可能的iCAA,在CSF中有β-粉样蛋白的证据,在6年的随访中显示出中度残疾 (mRS 3).
结论:
- iCAA是神经外科手术后可能发生的介导病理,因此在有手术史的年轻ICH患者中需要怀疑.
- 识别iCAA的临床和放射性特征对于及时诊断至关重要.
- 为了全面了解和管理这种不断变化的病理,需要标准化的诊断标准和多中心注册表.

Amyloid Fibrils
9.3K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Alzheimer's Disease: Overview
449
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...
