概括
偏头痛涉及神经元白色和灰色物质的损失,随着慢性恶化而恶化. 这种灰质神经元损伤与神经递质变化有关,提供了新的治疗见解.
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:
- 人们对偏头痛的病理生理学知之甚少,这阻碍了有效的治疗.
- 神经成像研究表明,偏头痛中存在异常的大脑功能连接和宏观结构变化.
- 神经元可塑性和神经递质失调与偏头痛发作和慢性有关.
研究的目的:
- 用多式神经成像来调查偏头痛中的微观结构和神经递质变化.
- 提供对偏头痛病理机制和潜在治疗点的新见解.
主要方法:
- 扩散张力成像 (DTI) 和神经元定向分散和密度成像 (NODDI) 用于评估白质 (WM) 和灰质 (GM) 微观结构.
- 基于管道的空间统计 (TBSS) 和基于表面的分析 (SBA) 比较了慢性偏头痛 (CM),偶发性偏头痛 (EM) 和健康对照 (HCs) 之间的微结构差异.
- 朱空间工具箱分析了转基因神经元变化和神经递质之间的相关性.
主要成果:
- 偏头痛患者在WM中显示神经元密度指数 (NDI) 降低,与HC相比.
- 与EM患者相比,慢性偏头痛 (CM) 患者在WM中表现出降低的NDI和分数异质性 (FA),以及增加的辐射扩散性 (RD).
- 皮质转基因显示偏头痛和CM组的特定区域的神经元较少,损伤与神经递质负相关.
结论:
- 在偏头痛患者中,神经质损失存在于WM和皮质GM中.
- 轴突损伤似乎随着偏头痛进展到慢性而增加.
- 皮层转基因神经元损伤与神经递质水平的改变有关.

Degenerative Disc Disease I: Introduction
29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology
30
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
