Dion shared that she was diagnosed with a “very rare” progressive neurological disorder called stiff person syndrome, surely the first time most people had heard of it.
“As you know, I've always been an open book,” she said in an Instagram video. “I wasn't ready to say anything before, but I am now. I have been dealing with health issues for a long time and it has been very difficult for me to face these challenges and talk about everything what's happening. I'm through.”
She suffered from muscle spasms that affected “every aspect” of her daily life, Dion said, making walking difficult at times and, sadder still, it would be impossible for her to go on tour again as she had planned.
“I work hard every day with my sports medicine therapist to regain my strength and ability to perform again,” Dion said. “But I have to admit it was a struggle.”
According to National Institutes of HealthSymptoms include muscle stiffness in the torso, arms, and legs, as well as increased sensitivity to noise, touch, and emotional distress, all of which can trigger muscle spasms.
