Céline Dion was filmed enduring an excruciating 10-minute-long “seizure” provoked by Stiff Person Syndrome (SPS). A clip of the vulnerable scene was featured in the singer’s new documentary, I Am: Céline Dion, which was released worldwide on Prime Video on Tuesday (June 25).

In the heartbreaking segment, the 56-year-old talent could be seen writhing in pain, tearful, and flushed while lying on an examination table, unable to move.

The scene displayed the Charlemagne, Québec, native having a physical therapy session shortly after viewers saw her recording a new song titled Love Again.

As Céline was filmed gasping for air, medical professionals surrounding her were seen working to alleviate her painful muscle spasms. Eventually, a healthcare professional was seen administering a nasal spray to the songstress.

Her physician, Dr. Amanda Piquet, director of the autoimmune neurology program at the University of Colorado Anschutz Medical Campus, told Today on Tuesday that Céline had received benzodiazepine nasal spray, which is part of a class of depressant drugs that relieve anxiety and reduce muscle spasms.
