Multiple Sclerosis and Dance
Worldwide, 2.5 million people have been diagnosed with multiple sclerosis. In the US, approximately 10,000 to 15,000 new cases are diagnosed every year. Multiple sclerosis (MS) is a chronic disease of the central nervous system, which is made up of the brain, spinal cord, and optic nerve. The nerves in the CNS are surrounded by a protective fatty material called myelin. It is believed that in MS the immune system attacks the central nervous system, the myelin is damaged – resulting in the formation of dense, scar-like tissue. These scars (also known as lesions) occur in many places throughout the central nervous system. 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. The result may be symptoms that could be moderate, such as numbness in the limbs, or severe, such as paralysis or loss of vision. The progress, severity, and specific symptoms of multiple sclerosis are unpredictable and vary depending on the individual. While the specific cause of MS is unknown, scientists and doctors are exploring four possible areas that may trigger the onset of the disease, immunology, environment, genetics, and infections.
There are four types of multiple sclerosis. Each type has its own unique symptoms and patterns. The first is called Relapsing-remitting MS (RRMS). 85% of initial MS diagnoses RRMS. People with RRMS have isolated relapses when symptoms may appear or resurface. The relapses are followed by periods of time when a person experiences fewer symptoms or none at all. The second type is called Secondary-progressive MS (SPMS). 50% of people with RRMS develop SPMS. This typically happens gradually, typically within ten years within the initial diagnosis. People with SPMS experience fewer relapses, however, their disability worsens and symptoms may become pronounced. The third type is called Primary-progressive MS (PPMS)....
