Multiple Sclerosis by definition simply means an autoimmune disease that affects the central nervous system (which is the brain and spinal cord.) This particular disease is more commonly found in young adults ranging from early twenties to early forties. A higher percentage of the individuals affected by Multiple Sclerosis are female as well.
Multiple Sclerosis affects ability of nerve cells in the brain and spinal cord to communicate with each other. The exact cause of this disease is still not entirely known but most believe Multiple Sclerosis is resulted from damage of the myelin sheath. The myelin sheath is the protective material that surrounds each nerve cell in the human body. Scientists have found that this disease is a progressive one, this means over time the nerve damage get worse and worse.
Inflammation is yet another symptom of Multiple Sclerosis. When the body’s own immune cells attack the nervous system, inflammation occurs. The inflammation destroys the myelin (which is crucial tissue) leaving many areas of the body’s skin covered with scar tissue. This scar tissue is named sclerosis, which is where multiple sclerosis got its name. The brain and spinal cord are what controls a human’s ability to react to their external environment. Multiple Sclerosis creates repeated episodes, or flare ups, of inflammation along the brain and spinal cord which causes human impulses to slow down or become blocked. Symptoms vary because the location and extent of each attack varies. Episodes that last days, weeks, or months alternate with times of reduced or no symptoms (remission). Recurrence (relapse) is common although non-stop progression without periods of remission may also occur.
Scientists are not entirely sure what causes an individual to catch Multiple Sclerosis, but they have found that individuals diagnosed with this disease are more commonly found in northern Europe, the northern United States, southern Australia, and New Zealand. They believe...
