Celine Dion reveals that she has a rare neurological disorder and must cancel shows on her world tour

Celine Dion revealed that she is suffering from "stiff-person syndrome" and the symptoms are forcing her to cancel some appearances on her world tour.

The French-Canadian singer announced her difficult diagnosis in an emotional video on Instagram Thursday.

"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," Dion said in the video.

"Unfortunately these spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I'm used to," she added. "I have to admit it's been a struggle. All I know is singing, it's what I've done all my life."

SPS is very rare and only affects about one in a million people. The condition causes rigidity and stiffness in the limbs and torso, as well as muscle spasms. People with SPS are prone to falling down and hurting themselves over the symptoms, which are often triggered by stimuli like loud noises.

"I have a great team of doctors working alongside me to help me get better," she continued. "I'm working with my sports medicine therapist every day to build back my strength and my ability to perform again."

She went on to say that she was canceling and postponing performances scheduled for Europe on her world tour.

There is no cure for SPS, but there are treatments that can ease the severity of the spasms and other symptoms. The condition can also worsen over time.

"Take care of yourselves. Be well. I love you guys so much," she concluded her video in tears. "And I really hope I can see you again real soon. Thank you."
