Celine Dion suffering from rare neurological disorder

Celine Dion announced this week that she has been diagnosed with "stiff person syndrome," a rare and incurable neurological disorder that causes severe muscle spasms and stiffening in the limbs. The diagnosis came after the French-Canadian singer was forced to cancel shows over the past year due to difficulties walking and singing. "I've been dealing with problems with my health for a long time," Dion told her 5.2 million Instagram followers in a video. "And it's been really difficult for me to face these challenges and to talk about everything that I've been going through." Dion, 54, said her condition would prevent her from resuming her tour in Europe next February.
