What Causes Multiple Sclerosis

Multiple sclerosis can occur in many people. This disease is developed when damage to the nerve fibres of the central nervous system is produced. This is why MS commonly is described as an autoimmune disease. Why the immune system attacks the myelin is something that still remains unknown. However, many specialists have tried to answer the question what causes multiple sclerosis.

Some specialists say that MS is most commonly developed due to a combination of many causes, including genetic and environmental factors. In different cases, the development of MS may be caused by the genes inherited from the parents or by outside factors that can favor the development of this disease.

Still, the disease cannot be classified as a genetic condition, as there is no single gene that determines its development. However, some studies have shown that different combinations of genes make developing MS more likely.

Other studies have shown that what causes multiple sclerosis is actually linked to the content of vitamin D existent in the body. MS is more common in countries that are far away from the Equator, due to the lower amounts of vitamin D contained by the people’s bodies, as these countries are less exposed to sunlight. Lower levels of vitamin D have been associated to this disease.

Viral infection may be a cause of multiple sclerosis, too. Such an infection affects the immune system’s ability to work properly. One of the newest theories on the development of multiple sclerosis indicates that in fact it might be caused by problems with the flow of blood in the body.

Still, the cause of multiple sclerosis remains unknown. However, all researchers claim that this condition is caused by a combination of more than one factor. This condition is not a hereditary one, but family history with MS may be an important risk factor in the development of the disease.

Specialists cannot know for sure what will cause MS and they cannot predict how this disease will evolve after its development. This is why specialists commonly recommend patients to be careful at all symptoms, even though they may not be very persistent. Tracing MS soon will help patients access the right treatment that will stop its progression in time.
