概括
白质高强度 (WMHs) 在患有皮下渐进性上核性麻 (PSP) 和皮质基底综合征 (CBS) 的患者的深静脉区域更为普遍. 这表明静脉系统功能障碍在这些四重复的病变中可能发挥作用.
科学领域:
- 神经退行性疾病的神经退行性疾病
- 神经病理学神经病理学
- 血管神经学 血管神经学
背景情况:
- 渐进性上核性麻 (PSP) 和皮质皮质综合征 (CBS) 是影响常见大脑网络的4重复 (4R) 类型病变,涉及不同的皮质和皮质下皮质.
- 白质超强度 (WMHs) 在神经退行性疾病中很常见,但它们在4R-tauopathies中的分布尚不清楚.
研究的目的:
- 为了研究WMHs在皮层和皮层下主要的4R-tauopathies的分布.
- 使用基于静脉区域和分层的图谱进行详细的WMH分析.
主要方法:
- 招募了95名PSP或CBS (64个皮层,31个皮下) 和50个对照的参与者.
- 在表面,深静脉和围静脉区域计算WMH体积.
- 创建了一个分层的地图库来评估从侧心室到大脑表面的WMH.
主要成果:
- 与皮层组相比,皮层组在深静脉区域表现出更多的WMH (p=0.04).
- 皮下组的WMH集中在5-10层 (12-30毫米从侧心室) (p≤0.01).
- 皮质下变体报告了更多的中风病史,慢性脏病和头痛.
结论:
- 在深静脉区域和流域中WMH的分布表明4R-tauopathies中的潜在静脉系统功能障碍.
- 静脉功能障碍可能有助于4R-tauopathies的发病,特别是皮质下形式.

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

4.2K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
