Singer Celine Dion disclosed Thursday morning that she suffers from a “very rare neurological disorder called stiff-person syndrome” in an emotional video that was shared on her official Instagram page.

Celine announced the news on Instagram, writing:

“I have been struggling with health issues for a while, and I find it quite challenging to talk about all that I’ve been going through and to face these challenges. “It pains me to inform you that I will not be prepared to resume my European tour in February,” she wrote in the post.

“A rare autoimmune movement disorder that affects the central nervous system (the brain and spinal cord)” is stiff-person syndrome. According to the Cleveland Clinic, people with this illness initially experience a stiffening of their trunk muscles, which is followed over time by the development of stiffness and rigidity in the legs and other body muscles.

She claimed that every element of her daily life, including singing and walking, is impacted by the spasms she has been having, which are reportedly a symptom of the syndrome.

She went on to explain that she’s been diagnosed with a neurological condition called stiff person syndrome, which is causing her to have severe spasms. As a result, she’s understandably taking time to focus on her recovery.

According to the Cleveland Clinic, this condition affects about one person in every one million people. There is no known treatment for it, and its cause is unknown.

Dion stated that in order for her to be able to perform again, her medical team will assist her in managing her symptoms.
