The demyelination happens in patches along the length of the axon, so it's called segmental demyelination.

因为轴突上只发生局限性的脱髓鞘，因此又称为节段性脱髓鞘。

In multiple sclerosis, demyelination happens when the immune system inappropriately attacks and destroys the myelin, which makes communication between neurons break down, ultimately leading to all sorts of sensory, motor, and cognitive problems.

多发性硬化在发生脱髓鞘时，免疫系统异常攻击破坏髓鞘，中断神经元之间交流，最终出现一系列的感觉、运动和认知障碍。
