什么是多发性硬化症_多发性硬化

内容

multiple sclerosis is an immune mediated disease

多发性硬化症是一种免疫介导的疾病

in which the body's immune system attacks the nerves in the brain and spinal cord

身体的免疫系统攻击大脑和脊髓的神经

this disrupts the flow of nerve signals throughout the body

这会扰乱全身神经信号的流动

nerve fibers have a protective sheath called myelin which insulates the nerves

神经纤维有一个称为髓磷脂的保护鞘,可以使神经绝缘

aiding the fast transmission of electrical signals along the nerve fibers

帮助电信号沿着神经纤维快速传输

in multiple sclerosis

在多发性硬化症中

an unknown trigger causes the immune cells to start attacking and breaking down the myelin sheath

未知的触发因素导致免疫细胞开始攻击并分解髓鞘

over time repeated damage causes hard Scar Tissue known as Plax to form on the nerve

随着时间的推移,反复损伤会导致神经上形成称为Plax 的硬疤痕组织

as a result the nerve impulses are disrupted

结果神经冲动被扰乱

because the electrical signals can't travel as fast and may leak out between the damaged mland

因为电信号无法快速传输并且可能会在损坏的基板之间泄漏

Vision speech movement and sensation can all become affected

视觉、言语、运动和感觉都会受到影响,

as these functions require effective communication between nerves

因为这些功能需要神经之间的有效沟通
