Celine Dion made a triumphant return to the stage at the Olympic opening ceremony, marking her first performance since being diagnosed with stiff person syndrome. This rare neurological condition is characterized by spasms, muscle rigidity, and heightened sensitivity to stimuli like sound and lights. The severity of these spasms can be so intense that they may lead to bone fractures, and any fall could result in serious injury, according to experts.
Stiff person syndrome is an exceptionally rare disorder, with only about 1 in every 1 million individuals developing it. Most general neurologists encounter just one or two cases in their entire careers. The condition can manifest at any age and is known to affect twice as many women as men.
