Celine Dion Has Lost Control of Her Muscles, Her Sister Confirms

Celine Dion Has Lost Control of Her Muscles, , Her Sister Confirms. Dion was diagnosed with a rare neurological condition known as Stiff-Person Syndrome last year.

In a new interview with '7 Jours,' Dion's sister, Claudette, shared an update about the singer's health, according to 'The Hollywood Reporter.'.

She said that Dion "is working hard [to battle through her disorder], but she doesn’t have control of her muscles." .

What pains me is that she’s always been disciplined.

She’s always worked hard.

Mom always said to her: ‘You will do well, you will do things as they should be done.’ , Claudette Dion, via '7Jours'.

There’s no doubt that in our dreams and in hers, the idea is to come back to the stage.

In which state?

I don’t know.

The vocal cords are muscles, and the heart is also a muscle, Claudette Dion, via '7Jours'.

Claudette went on to say that science hasn't found a way to treat the condition yet.

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, Claudette Dion, via '7Jours'.

You know how people often jump up in the night because of a cramp in the leg or the calf?

It’s a bit like that, but in all muscles.

There’s little we can do to support her, to alleviate her pain, Claudette Dion, via '7Jours'
