Stiff person syndrome is an uncommon neurological disorder that causes muscular spasms and stiffness. It can be caused by a variety of stimuli, including sound, light, and emotional discomfort, according to the National Institute of Neurological Disorders and Stroke.

Dion, who initially revealed her illness in 2022, has had to postpone her tour and live engagements owing to her health.

"I want to send my encouragement and support to all those around the world that have been affected by SPS. I want you to know you can do it! We can do it!." she concluded.
