1. Worldwide, 2.5 million people have been diagnosed with MS 2. In the US approximately 10,000 to 15,000 new cases are diagnosed every year. 3. The chance of getting multiple sclerosis, on average, is 1 in 750. 4. While anyone can get MS, it is 2 to 3 times more common in women than in men. 5. MS occurs in most ethnic groups but is more common among people of northern European descent 6. Multiple Sclerosis (MS) is a chronic disease of the central nervous system (CNS) 7. The nerves in the CNS are surrounded by a protective fatty material called myelin. 8. In MS, it is believed that when the immune system attacks the CNS, the myelin is damaged. 9. When the Myelin is destroyed it results in the formation of dense, scar-like tissue. 10. These scars (also known as lesions) occur in many places throughout the CNS, hence the name "multiple sclerosis", or many scars. 11. The scar tissue affects the way electrical impulses travel along the nerve fiber, distorting and interrupting signals coming to and from your brain and spinal cord. 12. This may result in symptoms that could be mild, such as numbness in the limbs, or severe, such as paralysis or loss of vision. 13. The progress, severity, and specific symptoms of MS are unpredictable and vary from one person to another. 14. If someone in your immediate family has MS, your chance of developing MS may increase. 15. MS is not directly hereditary, although genetic susceptibility plays a part in its development.
