Multiple sclerosis is a chronic illness of the central nervous system. In this article, we'll go over causes, types, symptoms, medications, and much more. Multiple sclerosis is a disease that causes breakdown of the protective covering of nerves. Multiple sclerosis can cause numbness, weakness, trouble walking, vision changes and other symptoms. It's also known as MS. In MS, the immune system attacks the protective sheath that covers nerve fibers, known as myelin. This interrupts communication between the brain and the rest of the body. Multiple sclerosis isn't usually fatal, and life expectancy has improved, but life-threatening complications can impact MS progression. Multiple sclerosis (MS) symptoms are varied and range from pain to vision problems to mobility issues.

Multiple sclerosis (MS) is a central nervous system autoimmune condition. Damage to myelin causes symptoms like muscle weakness and vision changes. Multiple sclerosis (MS) is an autoimmune disease where the immune system attacks myelin, the insulating cover of nerve cells in the human body, causing damage to one's own central nervous system. [1] It is a type of demyelinating disease, where the nervous system's ability to transmit signals is damaged. Symptoms can be physical, mental, or both, [1] including double vision, vision loss, eye.
