There are many debates over the specific causes of multiple sclerosis. However, in the absence of conclusive evidence, medical scientists can only speculate upon the causes and risk factors behind multiple sclerosis and other similar autoimmune diseases. Although certain theories regarding a series of multiple sclerosis specific triggers have been partially confirmed by recent medical studies, doctors need additional data in order to identify the exact set of multiple sclerosis causes.

At present, medical scientists believe that genetic factors play a major role in the occurrence and development of multiple sclerosis. However, the specific genes involved in triggering the disease haven’t yet been identified. It is suspected that multiple sclerosis occurs due to a combination of genetic factors corroborated with a series of environmental factors. The autoimmune response characteristic to multiple sclerosis is also believed to be triggered by prolonged exposure to chemicals (long-term treatments with chemotherapeutic drugs are suspected to facilitate the development of multiple sclerosis) or by past infections.
