概括
不成比例地扩大的脑下下空间水脑 (D+E+) 存在于约15%的渐进性上核性患者中. 这种情况与更糟糕的临床结果和成像发现有关,这表明神经退行症的作用.
科学领域:
- 神经科学是一个神经科学.
- 放射学 放射学是一门学科.
- 神经学 神经学
背景情况:
- 正常压力脑症 (NPH) 的特点是走路障碍,认知障碍和尿失禁,MRI显示了扩大的脑下腔空间.
- 步态障碍在帕金森症中很常见,但水头在这些疾病中的作用和患病率尚不清楚.
研究的目的:
- 确定在帕金森氏症疾病中MRI上的水头指标的流行率.
- 调查这些成像发现与临床特征和其他MRI/PET异常的关联.
主要方法:
- 214名患有帕金森氏症的参与者 (包括渐进性超核性,皮质核综合征,帕金森病) 接受了MRI和PET扫描.
- 使用自动检测不成比例扩大的甲状腺下部空间 (D) 和埃文斯指数 (E) 来进行分类:D+E+,D+E-,D-E+,D-E-.
- 临床,人口和成像数据 (包括缩,白质高强度和新陈代谢) 在各组之间进行了比较.
主要成果:
- 大约15%的参与者显示成像暗示水头发症 (D+E+),主要是渐进性上核性麻 (PSP) 病例 (11%).
- 与D+E+参与者相比,D+E+参与者年龄较大,与D-E-.相比,他们表现出更多的迷失方向,俯视麻,中脑/皮层缩,较低的条状代谢,以及较大的白质退化和强度过高.
- 与D-E-.相比,D-E+参与者表现出更严重的疾病严重程度和更大的缩.
结论:
- 在约15%的PSP患者中发现不成比例地扩大的甲状腺下大脑,与较差的临床和成像结果相关.
- 该研究假设PSP中扩大的脑下腔空间可能是退化和脑脊液再分配的结果.

01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
