Inflammation creates areas of damage called lesions. Most people start with a relapsing-remitting pattern: attacks of new symptoms, followed by partial or full recovery. Some people later develop slow, steady progression.
Who gets it
MS is two to three times more common in women and is usually diagnosed between 20 and 40. Low vitamin D, smoking, and past Epstein-Barr virus infection are linked to a higher risk.

Fatigue and changes in thinking or memory
Labs to ask about
MRI of the brain and spinal cord
