Global MS prevalance data
Canada has one of the highest rates of multiple sclerosis in the world, according to an international survey.
The 2008 Atlas of Multiple Sclerosis suggests that MS strikes as many as 240 out of every 100,000 people in Canada. That's the fifth highest rate among countries surveyed. According to the atlas, the median age of onset of symptom is 24.5 in Canada — and women are twice as likely as men to be diagnosed with the condition.
