【評論內容】In MS, for reasons still unknown, the body’s immune system attacks the myelin insulation of nerve fibers. This can cause some of nerve fibers to die, while others become ineffective during a prolonged period of regeneration. The effects of this nerve damage can include reduced or spasmodic control of the body, and lowered capacity or disruptions of the senses. 在多發性硬化症中,由於未知的原因,身體的免疫系統會攻擊神經纖維的髓鞘絕緣層。 這可能會導致一些神經纖維死亡,而另一些神經纖維在長時間的再生過程中變得無效。 這種神經損傷的影響可能包括身體控制力減弱或痙攣,以及感覺能力降低或破壞。(A) 寒冷的溫度。(B) 傷口感染。(C) 神經受損。(D) 以上皆非。
