Celine Dion's long-lasting career: What to know about the Canadian singer

Fox News Digital looks at Celine Dion's career highs and lows after the Canadian musician revealed she'd been diagnosed with an incurable neurological disease known as stiff person syndrome.

"Unfortunately, the spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I’m used to," she said.

Stiff person syndrome causes rigid muscles and painful muscle spasms, which can be triggered by such things as loud noises or light touch. The cause isn’t known, but it is thought to be an autoimmune disorder. Severe cases can cause difficulty walking and hunched posture.
