Celine Dion‘s sister Claudette Dion shared a new update on the singer’s health amid her struggles with Stiff-Person Syndrome. In a recent interview with 7 Jours (translated from French by The Hollywood Reporter), Claudette said the 55-year-old “is working hard [to battle through her disorder], but she doesn’t have control of her muscles.” She also lamented that there’s not enough scientific advancement yet to treat the condition: “That’s what is so upsetting to me. Since these cases are one in a million, scientists have not done that much research since it doesn’t affect that many people.”
