For Immigrants to Canada, Risk of MS Increases with Proportion of Life Spent There
American Academy of Neurology (AAN)Immigrants to Canada who have spent a greater proportion of their lives in Canada have a greater risk of developing multiple sclerosis (MS) than people who have spent a smaller proportion of their lives there, according to a study published in the April 24, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that an increased proportion of life in Canada causes MS; it only shows an association.
