Celine Dion's Battle with Stiff-Person Syndrome: Loss of Muscle Control

Celine Dion's sister, Claudette Dion, has provided an update on the singer's health condition, revealing that her struggle with stiff-person syndrome, a rare neurological disorder, has worsened. Claudette stated that Celine "doesn't have control over her muscles" and expressed Celine's desire to return to the stage, although the capacity in which she would be able to do so remains uncertain. Celine had previously announced her diagnosis of stiff-person syndrome in December 2022 and has since faced difficulties in her daily life, including walking and singing. Stiff-person syndrome is a rare autoimmune movement disorder that causes chronic pain and muscle spasms.
