Céline Dion Battles Rare Disease, Cancels Tour

Singer's struggle with Stiff Person Syndrome prompts career hiatus, hopes for future return to stage remain.

Céline Dion has been diagnosed with Stiff Person Syndrome, a rare disease that causes the body to stiffen and can be triggered by sounds, light, touch, or emotional stress.
The disease has caused Dion to lose control over her muscles, affecting her ability to perform and prompting her to cancel her 2023-2024 world tour.
There is no known cure for Stiff Person Syndrome, but it can be managed with specific treatments including antibody injections, anti-anxiety drugs, and muscle relaxants.
Dion's sister, Claudette, has shared that the singer is working hard to recover and hopes to return to the stage, though it is unclear in what capacity.
Stiff Person Syndrome is thought to be an autoimmune disorder, affecting fewer than 5,000 people in the U.S., and is more common in women than men.
