Multiple Sclerosis
Multiple Sclerosis is a disease of the central nervous system that causes increasing physical and mental disabilities. The disease process causes a breakdown of the myelin sheath (protective coating) of the nerve cells that causes a great many diverse symptoms; pain and weakness in the body as well as mental and psychiatric symptoms.
The progress of the disease varies between individuals and is known to go into remission for varying periods of time. The cause of this condition is unclear but is believed to be a destruction of the immune system that may be associated with genetic and/or environmental factors or infections. There is no known cure at this time.
