Summary: <p>As many as one in 500 Americans has multiple sclerosis. Ann Romney, wife of the Republican presidential nominee, has MS. So did first lady Michelle Obama's late father. It's believed to be an autoimmune disease that damages neurons in the brain and spinal cord, sometimes leading to permanent disabilities. There is no cure, but there are a number of treatments available to alleviate symptoms and possibly slow the progression of the disease. Some of the most effective MS drugs can cause dangerous side effects. But one promising new drug won FDA approval earlier this month, and a decision on another drug is expected by year's end. Guest host Susan Page will talk with a panel of experts, including a doctor who has MS, about diagnosing, treating and living with multiple sclerosis.</p>
