What is multiple sclerosis?

Multiple sclerosis (MS) is a chronic, often disabling disease of the central nervous system comprising the brain, spinal cord, and optic nerve. The disease is unpredictable and affects each individual differently. Symptoms include fatigue, cognitive impairment, lack of coordination, and vision problems.

Canada has one of the highest rates of MS in the world with 11 Canadians diagnosed with MS every day. Currently, there is no cure but each day researchers are learning more about what causes MS and are zeroing in on ways to prevent it.
