Causes of Multiple Sclerosis
No one has a definitive idea on the specific causes of multiple sclerosis. The best reasons experts were able to come up with are four theories all of which merely attempt to explain multiple sclerosis. However, none of these theories offer a thorough explanation.
Essentially, the potential cause of multiple sclerosis may be the interaction of all the theories combined, namely genetics, the immune system, infectious diseases and the environment.
Researchers agree that multiple sclerosis is caused when the immune system attacks the body. Basically, the T-cells of the immune system attack spinal cord cells as well as brain cells. The impact of the damage will dictate the function of the affected nerves thereby resulting in multiple sclerosis symptoms and disability.
Environment-wise, it has been discovered that that people in specific areas have a potential risk of acquiring multiple sclerosis compared to others. Researchers also realized that one' s risks of having multiple sclerosis change as based on one' s specific location.
Take note that multiple sclerosis occurs in regions which are far from the equator. Some even believe that the lack of vitamin D causes multiple sclerosis as those regions distant from the equator receive less sun exposure thereby decreasing the production of vitamin D in the body.
Researchers also believe that viruses are the cause of multiple sclerosis. Specifically, infections have the ability to trigger the body' s immune system and assault the nerve cells.
The virus which causes the infection primarily resemble a nerve cell. The immune system then develops certain T-cells in order to battle the virus. The T-cells then stay in the body even after the infection has disappeared. They then become confused whenever they spot a nerve cell and perceives it as a foreign invader. The end-result is the body' s immune system drastically attacking the nervous system.
Genetics also plays a role in the development of multiple sclerosis. It is seen that one' s chances of getting multiple sclerosis increases when one has a relative which has multiple sclerosis. Also, experts believe that specific genetic combinations intensify the risk of multiple sclerosis.
For one, your risk of having multiple sclerosis is one in a thousand if you have no family members or relatives with multiple sclerosis.
Meanwhile, your risk of developing multiple sclerosis is one in a hundred if you have a grandparent or any other 2nd degree relative who have multiple sclerosis.
Mainly, your risk of developing multiple sclerosis increases, specifically you have one in forty chances of acquiring multiple sclerosis if your sibling or your parents have MS. Also, if you have an identical twin who has multiple sclerosis, your risk is one in four.
