Celine Dion has been diagnosed with stiff person syndrome, a rare neurological condition that causes spasms and muscle rigidity. This condition has caused her to cancel her "Courage World Tour" dates through 2024. Dion postponed several performances in December 2022 after learning the reason for her muscle pain and difficulties with mobility. Despite undergoing daily physical therapy, she is still in a lot of pain. In May 2023, Dion announced the cancellation of her remaining tour for health reasons. She is working hard to build back her strength, but touring can be very difficult even when youre 100% . Dion has a great team of medical professionals and her childrens support. She is determined to return to the stage at some point. Her sister Claudette Dion said that Celine is "doing everything to recover," while they continue "crossing our fingers that researchers will find a remedy for this awful illness".
