Celine Dion has been keeping a low profile ever since she stepped out of the spotlight in October 2021 after revealing she was suffering from a debilitating health condition – and one year later, she revealed the rare disease she has finally been diagnosed with.

The singer shared the news with fans in December 2022 that she has been diagnosed with a rare neurological disorder called stiff person syndrome, which had been inducing the muscle spasms she’d dealt with that forced her to withdraw from performing. Her worsening health meant she canceled her Las Vegas residency and postponed the North American and European legs of her Courage world tour.

Sharing a video on social media, which you can watch below, Celine said that stiff person syndrome impacts “one in a million people,” before explaining how she is treating the condition.

What is wrong with Celine Dion?

Celine is battling a rare neurological disorder called stiff person syndrome. Speaking of her diagnosis, she said: “I’ve been dealing with problems with my health for a long time, and it’s been really difficult for me to face these challenges and to talk about everything that I’ve been going through.”

While Celine is recovering at her $1.2 million Las Vegas home, her sister Claudette shared an emotional – but positive – update on the famous singer.

Chatting to Le Journal de Montreal, Claudette said: “I am confident that life will give her back what she gave because she is an extremely intelligent woman, so very generous and talented and in love with life as well.”

She added: “Rather than crying over her fate, I try to send her positive vibes in the hope that one day she will go back on stage. I truly believe in the power of love. I wish her the best of luck, that’s for sure. She is surrounded by specialists as she continues to recover.”

What is stiff person syndrome?

Stiff person syndrome is a rare neurological disorder. Symptoms include muscle rigidity in the trunk and arms, often triggered by noise, touch, and emotional distress. Celine’s condition is characterized by muscle spasms.

People with stiff person syndrome suffer from frequent falls because they lack defensive reflexes to save themselves. Sufferers are often unable to walk or move, and it’s twice as common in women than in men.

When did Celine Dion’s health battle start?

Celine first publicly revealed she was suffering from poor health in October 2021. At the time, she revealed she was battling “severe and persistent muscle spasms” so was forced to delay her Las Vegas shows, and she’s not taken to the stage since.

When Celine canceled the North American leg of her tour in January 2022, she admitted that she thought she would have been in better health by then. “I was really hoping that I’d be good to go by now, but I suppose I just have to be more patient and follow the regimen that my doctors are prescribing,” she said.

In her initial statement, Celine said she was postponing her Las Vegas show until March 22 due to “unforeseen medical symptoms”.

“I’m heartbroken by this. My team and I have been working on our new show for the past eight months, and to not be able to open this November saddens me beyond words,” she said at the time.

“I feel so bad that I’m letting them down, and I’m especially sorry for disappointing all the fans who’ve been making their plans to come to Las Vegas. Now, I have to focus on getting better… I want to get through this as soon as I can. – Celine xx.”

When will Celine Dion perform again?

As of now, Celine has cancelled all her upcoming tour dates up until April 2024. Her website currently reads: “With a sense of tremendous disappointment, Celine Dion’s Courage World Tour today announced the cancellation of all remaining dates currently on sale for 2023 and 2024.”

In a personal statement, Celine said: “I’m so sorry to disappoint all of you once again. I’m working really hard to build back my strength, but touring can be very difficult even when you’re 100%. It’s not fair to you to keep postponing the shows, and even though it breaks my heart, it’s best that we cancel everything now until I’m really ready to be back on stage again.”

She continued: “I want you all to know, I’m not giving up… and I can’t wait to see you again!”

Celine’s Las Vegas residency also remains uncertain, as no new dates for shows have been revealed yet either.

What has Celine’s sister said about her condition?

Celine’s sister Claudette recently spoke to Canadian site showbizz.net to give an update on her sister’s treatment. Sharing a glimpse inside her loved one’s journey, Claudette said: “I know she went to Denver a couple of times because there are great researchers there and I’m crossing my fingers. That’s all we can do. Tell her how much we love her and that we wish her all the best.”

Meanwhile, during a televised appearance with Le Journal de Montreal, Claudette said: “When I call her and she’s busy, I speak to my sister Linda who lives with her and tells me that she’s working hard. She’s listening to the top researchers in the field of this rare disease as much as possible.”

“I honestly think that she mostly needs to rest. She always goes above and beyond; she always tries to be the best and top of her game. At one point, your heart and your body are trying to tell you something. It’s important to listen to it.”

And in an exclusive interview with HELLO! Canada, Claudette shared a hopeful update. Opening up, she said: “She’s doing everything to recover… She’s a strong woman.”
