Multiple sclerosis is a debilitating disease in which body's immune system eat away at the protective sheath that covers the nerves. Damage to myelin can produce interference in the communication between your brain, spinal cord and other areas of your body. This results in deterioration of the nerves themselves, it is a process that is not reversible. Symptoms of multiple sclerosis may vary, depending on the location of affected nerve fibers. Multiple sclerosis symptoms may include various factors: Numbness in one or more limbs, Partial or complete loss of central vision in eyes, usually in one eye, often with pain during eye movement (optic neuritis), Double vision i.e. blurring of vision, Tingling or pain in parts of your body, Electric-shock sensations that occur with certain head movements, Tremor, lack of coordination or unsteady gait, Slurred speech, Fatigue, Dizziness. Heat sensitivity is common in people with multiple sclerosis. Small increases in the body temperature can boost or worsen multiple sclerosis symptoms. The cause of multiple sclerosis is not known yet. It's believed to be an autoimmune disease, in which the body's immune system attacks its own tissues. In multiple sclerosis, this process destroys myelin i.e. the fatty substance that coats and protects nerve fibers in the brain and spinal cord. Myelin can be compared to the insulation on electrical wires. When myelin is damaged, the messages that travel along that nerve may be slowed or blocked.
