Wherever myelin is damaged, the message carried by the affected nerve becomes garbled or lost, altering the performance of some part of the body and demyelination occurs. The type of symptoms one experiences depends on which part of the central nervous system is demyelinated. The symptoms of MS vary greatly from person to person.
Symptoms can be mild or severe.
They may appear briefly and then subside, or they may last for a long time. People also experience different combinations of symptoms. Most people experience more than one symptom, but no one exhibits all of the possible symptoms. An individual's own symptoms can also vary from time to time. Remissions occur when myelin is able to repair itself.
