Celine Dion revealed in an Instagram video on Wednesday that she is battling an incurable rare neurological disorder.

In the video, a clearly emotional Dion is seen facing the camera directly addressing fans. The Canadian singer posted another video with the same message addressing her fellow French fans.

“Recently, I’ve been diagnosed with a very rare neurological disorder called Stiff Person Syndrome,” Dion said. “While we’re still learning about this rare condition, we now know this is what’s been causing all of the spasms that I’ve been having.”

Stiff Person Syndrome is an autoimmune and neurological disorder that causes muscles in the torso and limbs to alternate between rigidity and spasms. It affects one in one million people.

It can make walking difficult, which Dion has been experiencing. The disorder has also made it hard for the “My Heart Will Do On” singer to utilize her vocal cords. Therefore, Dion’s spring 2023 shows will be rescheduled to 2024 and eight summer 2023 show were canceled.

In the video, Dion goes on to apologize to her fans for the cancellation and assures that she is working hard with therapists and doctors to improve her health. She is also looking forward to making her way back to the stage and to her fans. 

“I want to thank you so much for your encouraging wishes of love and support on my social media,” Dion said. “This means a lot to me. Take care of yourselves. Be well. I love you guys so much and I really hope I can see you again real soon.”
