Celine Dion's Sister Provides Alarming Update on Singer's Neurological Condition

Celine Dion's sister, Claudette Dion, provided an update on the singer's battle with stiff-person syndrome, revealing that Dion has no control over her muscles. Stiff-person syndrome is a rare neurological disorder that causes rigidity and increased sensitivity to noise, touch, and emotional distress. Dion had to step away from performing last year due to the condition, and her sister expressed their hope for her return to the stage. The disease affects 1 in a million people, predominantly women, and is often associated with other autoimmune diseases. Treatment options include muscle spasm alleviating drugs and intravenous immunoglobulin therapy.
