Choose to Fight MS. Understanding what causes MS will speed the process of finding more effective ways to treat it, or prevent it from occurring.
In MS, an abnormal immune-mediated response attacks the myelin coating around nerve fibers in the central nervous system, as well as the nerve fibers themselves.
Epidemiologists are looking at variations in geography, age, gender, ethnic background, genetics, infectious causes and migration patterns.
The cause of MS has yet to be discovered. Scientists believe the disease is triggered by as-yet-unidentified environmental factor in a person who is genetically predisposed to respond.
The progress, severity and specific symptoms of MS in any one person cannot yet be predicted. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease.
