May is Multiple Sclerosis Awareness Month, and every May, the MS Society hosts its annual MS Walk, an event encouraging Canadians to come together to raise funds for research and support those affected by MS.
MS is a chronic autoimmune disease of the central nervous system. Since that includes the brain, spinal cord and optic nerve, MS can affect vision, memory, balance and mobility. It is considered an episodic disability meaning that the severity and duration of illness and disability can vary and are often followed by periods of wellness. It can also be progressive.
