Celine Dion has "lost control of her muscles" during her battle with Stiff Person Syndrome, her sister Claudette Dion has revealed.
Claudette told Canadian news show 7 Jours that Celine has not given up on her fight against the condition. The rare neurological condition Stiff Person Syndrome reportedly affects just one person in every million.
The incurable disease can cause debilitating muscle spasms and affects the central nervous system, specifically the brain and spinal cord.
"What breaks my heart is that she's always been disciplined," Claudette told 7 Jours.
"She's always worked hard. Our mother always told her, 'You're going to do it well. You're going to do it properly'."
She also said that Celine still harboured the dream of performing live again. In December 2022, Dion was forced to postpone several European tour dates after she was diagnosed with the condition, which impacted her ability to perform.
"It's true that in both our dreams and hers, the goal is to return to the stage," she said. "In what capacity? I don't know."
"The vocal cords are muscles, and the heart is also a muscle. This is what comes to get me. Because it's one out of a million case, the scientists haven't done that much research because it didn't affect that many people," US website Page Six quoted her as saying.
The interview comes just over a month after the 'My Heart Will Go On' singer was seen out in public for the first time in over three years.
She attended an NHL hockey game in Las Vegas and went to meet the team afterwards, posing for photographs with the team and manager.
"We had a beautiful visit at the game in Vegas yesterday. Thanks @celinedion for your generosity. The whole team is so happy to have met you and your family," a social media post from the Montreal Canadians' communications manager said at the time.
