Multiple Scerosis

Multiple sclerosis (MS) is a chronic disease that affects the nervous central system (CNS), which consists of the brain and spinal cord. Doctors and researchers believe is caused mainly due to an autoimmune disease, which means that the immune system attacks parts of the body, thinking it was a foreign substance.

Multiple sclerosis is caused when the body mistakenly directed antibodies and white blood cells to attack the myelin sheath that protects nerve cells in the brain and spinal cord. Get lesions formed in areas at random from the central nervous system of the white matter, which can be long or completely dim cut in parts of the body nerve transmission. The process of demyelination "interferes with the transmission of nerve impulses.

Generally, it has been that the condition usually improves with time, but it has been rising too, which is a continuous process which finally results in progressive disability. The type and severity of symptoms vary greatly, depending on the areas of CNS who are affected and who have been affected.

Over a million people around the world are affected by this disease, but it is commonly prevalent in the western hemisphere. Although the symptoms are varied, most multiple sclerosis patients suffer from partial or complete blindness, a tingling sensation, partial or complete paralysis of limbs, double vision, tremors or unsteady gait, fatigue and dizziness.

It is important to note that multiple sclerosis is a slow progressing disease with a long prognosis. However, the patients can go about their daily lives normally, except for some impairment for several years. Also, multiple sclerosis cannot be transmitted from a patient to a healthy person, as it is not communicable. Unfortunately at present, there is no permanent cure for multiple sclerosis, although there are drugs that are palliative in nature or that may slow down the progress of the disease. A few promising treatments are in the research or experimental testing stage. Multiple sclerosis may be the result of a genetic disposition or, in certain cases, it may be caused due to antibody reaction to the myelin sheath.
