Dion, 55, first disclosed in December 2022 that she had been diagnosed with Stiff Person Syndrome, which causes stiff muscles in the torso, arms and legs, with noise or emotional distress known to trigger spasms.'Trying to overcome this autoimmune disorder has been one of the hardest experiences of my life, but I remain determined to one day get back onto the stage and to live as normal of a life as possible,' Dion said in a post late Friday to mark International SPS Awareness Day.
''I am deeply grateful for the love and support from my kids, family, team and all of you!' she added in the post, accompanied by a photo of her smiling broadly and posing with her three sons.There is no cure for Stiff Person Syndrome, which is progressive, but treatment can help control symptoms. According to the US National Institutes of Health, SPS affects twice as many women as men.
