Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system which is composed of the brain and spinal cord. The disease attacks the myelin which is a protective covering wrapped around the nerves of the central nervous system.

• Canada is known as having the highest rate of MS in the world, at 240 cases per 100,000 people.
• Approximately 75,000 Canadians are living with MS and half of the population knows someone with the disease.
• The mean age of onset of symptoms is 25.
• More than three women have the disease for every one man.
