The leading cause of Multiple Sclerosis is not known. Environmental factors not yet identified may trigger the disease in certain predisposed individuals
Women are two to three times more likely than men to be diagnosed with MS, and most cases of MS happen between the ages of 20 and 50 years of age. How severe specific symptoms can get in any one person can not be predicted.
With Multiple Sclerosis, the myelin, central nervous system, and even nerve fibers suffer various degrees of damage making brain and spinal cord transmission weak in addition to other parts of the body.
Though the cause of MS still is unknown, scientist and research groups are studying the ways different elements involved interact with each other. Also, studies in immunology, epidemiology, and genetics are ongoing. Research groups are studying other infectious agents and how they may link to understanding what causes MS, ways to treat it effectively which could lead to a cure, and finally how to prevent its occurrence from ever happening.
