Multiple sclerosis (MS) is a chronic disease of the central nervous system. An autoimmune disorder, MS is an unpredictable condition that can be relatively benign, disabling, or even devastating. Some people with MS may be mildly affected, while others may lose their ability to see clearly, write, speak, or walk when communication between the brain and other parts of the body becomes disrupted. With MS, myelin (a fatty tissue that surrounds and protects the nerve fibers) is lost in multiple areas and that loss forms scar tissue called sclerosis. These areas are also called plaques or lesions. When damaged in this way, the nerves are unable to conduct electrical impulses to and from the brain.
Symptoms can be mild or severe and can last a long time or short time. Also, depending on what areas are affected, they can present in many different combinations. The most common symptoms that a patient may notice first are: Blurred or double vision, Visual color distortion, Pain and loss of vision, Difficulty walking and Sensations of pain, numbness, or “pins and needles”
