The nervous system is made up of the central nervous system and the peripheral nervous system. Multiple Sclerosis
Definition : Multiple sclerosis or MS is a disease that affects the brain and spinal cord, resulting in loss of muscle control, vision, balance, and sensation With MS, the nerves of the brain and spinal cord are damaged by one's own immune system. Thus, the condition is called an autoimmune disease.
CAUSES No one is sure what causes the body's immune system to go awry in multiple sclerosis. Some scientists believe that it is a combination of genetics and something in the environment to which the person was exposed to early in life. 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.
Signs and symptoms: 1.Partial or complete loss of central vision, usually in one eye, often with pain during eye movement (optic neuritis) 2.Double vision or blurring of vision 3.Tingling or pain in parts of your body 4.Electric-shock sensations that occur with certain head movements 5.Tremor, lack of coordination or unsteady gait 6.Slurred speech 7.Fatigue: you may feel tired even after a good night’s sleep 8.Dizziness Diplopia
