What is demyelination?
Demyelination means that the fatty material covering nerves, deteriorates. When the myelin goes, so does coordinated, quick, and efficient movement. This happens because myelin, think of it as insulation like that on an electric cable, allows the nerves it shields to send and receive impulses properly without interference. You want to push your chair away from the kitchen table and stand up. Before demyelination of the nerves involved in those acts, you did them easily and speedily with hardly a thought. After demyelination, you struggle or simply can’t do them. Quick flowing movement has become slow, confused, or impossible.
