what is m s disease

Multiple sclerosis (MS) is a chronic disease of the central nervous system, which includes the brain, spinal cord, and optic nerves. In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers, leading to communication problems between the brain and the rest of the body. This can result in a wide range of symptoms, including issues with mobility, vision, speech, and cognitive function. The cause of MS is not fully understood, but it is believed to be an autoimmune disorder, possibly triggered by a combination of genetic, environmental, and infectious factors. The disease course varies among individuals, with most people experiencing periods of new symptoms or relapses followed by periods of remission. While the exact cause of MS remains unknown, ongoing research is focused on understanding the complex interplay of genetic and environmental factors, as well as the role of the immune system in the development of the disease.
