A new W5 documentary, "Céline’s Silence," digs into the rare disorder that has put Celine Dion's career on hold, while hearing from her long-time collaborators, friends and family. 

For decades, Céline Dion has captured the hearts of Canadians with her powerful voice. The singer has been out of the spotlight ever since announcing she has been diagnosed with stiff person syndrome, a rare neurological disorder that causes muscle stiffness and painful spasms.

Stiff person syndrome occurs when the body’s antibodies attack enzymes in the central nervous system that work to control muscle movement. Only one or two people per million are afflicted with the disorder, and it affects women more than men.

This documentary reveals testimonies from medical experts on stiff person syndrome. Dion’s close friends and early collaborators share their wishes and fears about her heartbreaking health crisis.
