Celine Dion's Health Battle: Sister Reveals Worsening Neurological Disease

Celine Dion's sister, Claudette Dion, has provided an update on the singer's health battle with stiff-person syndrome, revealing that Celine "doesn't have control over her muscles." While the family remains hopeful that Celine will be able to return to the stage one day, the extent of her recovery is uncertain. Stiff-person syndrome is a rare neurological disorder that causes muscle spasms and can be debilitating. Celine Dion first revealed her diagnosis in December 2020 and has since canceled all remaining concerts.
