Multiple Sclerosis, often called MS, is a disease that affects the central nervous system (CNS): the brain, spinal cord, and optic nerves.
I am not a scientist or even an educated researcher, I’m simply a woman living with MS. My almost 20 years of life with this condition has led me to many questions. Like many average people, I look online to have my questions answered. Wikipedia and YouTube have answers to most questions.
The problem is that one question leads to another.
What is actually happening in the body with progressive MS? One theory was shared by the MS society is possibly if the myelin is the only part of the central nervous system being attacked then new myelin sheath can be formed but if the whole cell, the Oligodendrocytes is damaged then repair tends very poorly.
Oligodendrocytes are found only in the CNS. It sounds to me that the Oligodendrocytes form myelin. Wikapedia has a great write up about Oligodendrocytes you can read it right here.
Knowledge is important, and it helps to have an understanding about this condition MS condition.
