A resurfaced clip of Celine Dion shaking and crying uncontrollably has reignited concerns amongst her fans. The harrowing footage shows the iconic vocalist evidently trembling and grappling with involuntary movements whilst being filmed.

The clip, which has lately spread across social media platforms, originates from Dion's intimate documentary I Am: Celine Dion and showcases a distressing episode during her continuous medical struggle. Within the video, Dion can be seen enduring what appears to be severe muscular contractions, prompting alarm from viewers. On X/Twitter, one fan declared: "This is hard to watch," while another said: "I don’t think this should have been documented, what’s the intention behind it?" One more said: "This is heartbreaking. Sending her loads of love."

One more person added: "This is just one moment of her journey. She has gotten better with ongoing treatment. This video is from 2024. I think it's important to see that celebrities don't all have it easy just because they are rich and famous.

"They are humans just like us, going through life's highs and lows."

The Canadian superstar has openly disclosed her diagnosis of stiff-person syndrome - an uncommon neurological condition affecting the brain and spinal cord.

The ailment triggers acute muscular rigidity and abrupt, unmanageable contractions which may be activated by tension, physical activity, or psychological pressure.

Dion has previously stated that the condition has significantly affected virtually all facets of her everyday existence, particularly her capacity to take to the stage and perform vocally.

The Grammy-winning artist initially revealed her diagnosis in late 2022 and later postponed and cancelled numerous tour dates whilst concentrating on treatment and recuperation.

Since that time, she has predominantly withdrawn from public view, opting to prioritise her wellbeing whilst receiving ongoing therapy under medical guidance.

Whilst there is no known cure for stiff-person syndrome, treatment can assist in managing symptoms.

Dion's choice to chronicle her journey has contributed to raising greater awareness of the condition and highlighting the challenges encountered by those living with rare neurological disorders.
