What causes clinically isolated syndrome?

ANSWER

When you have clinically isolated syndrome (CIS), your body attacks and damages the protective coating around your nerves, called myelin. That keeps your nerves from sending signals the way they should. It's what causes your symptoms. Doctors aren't sure why the body attacks itself this way. Some think a virus could be to blame, but the exact cause of CIS is unknown. Women and people between the ages of 20 and 40 have a higher risk of getting the condition.
