Céline Dion's sister Claudette says Celine has lost control over her muscles amid battle with stiff-person syndrome.
In a recent interview Claudette Dion revealed that there are some who have lost hope because it is a disease that is not very well known.
The elder Dion explained that while the singer (and her family) hope to see her back onstage, the progression of her illness has left them uncertain.
Scientists haven’t done that much research on the disease because it does not affect many people.
In December last year the singer announced her diagnosis in an emotional video, where she shared that the rare disorder “affects something like one in a million people.”
