Celine Dion's Battle with Stiff-Person Syndrome: Losing Control of Muscles

Celine Dion's sister, Claudette Dion, has provided an update on the singer's battle with stiff person syndrome (SPS), a neurological disorder that causes muscle rigidity. Claudette revealed that Celine no longer has control over her muscles, which has affected her ability to sing and perform. Celine had previously canceled tour dates and is now uncertain about returning to full-scale touring. The rarity of the condition has limited research into a cure, but Celine and her family remain hopeful and grateful for the support they receive from fans. SPS symptoms can be triggered by environmental stimuli or emotional stress.
