Legendary singer Celine Dion has canceled her Courage World Tour due to an ongoing battle with a rare neurological condition called Stiff-Person Syndrome. The condition causes muscle stiffness and spasms, making it difficult for her to walk and sing. Dion has been working with a sports medicine therapist to manage her symptoms but has not yet recovered enough to resume performing. The upcoming documentary “I Am: Celine Dion” will explore her journey with the condition and aims to raise awareness about Stiff-Person Syndrome.
