"The sensation is happening again," Yepes said in the video, her speech already slurred. "Smile they said. It's all tingly on the left side."

"On the — left — side," she repeated again, this time trying to enunciate the words.

She knew that she should breathe deeply and try to control her stress levels, but something as simple as lifting her hand was difficult.

Yepes, 49, went back to the hospital in Toronto, and this time she had proof that it couldn't just be stress.

"I think it was just to show somebody, because I knew it was not stress-related," she said in an interview with CBC News. "And I thought if I could show somebody what was happening, they would have a better understanding."

With the help of the video, specialists at Toronto Western Hospital's stroke center diagnosed Yepes with a transient ischemic attack, or a mini-stroke.

Ischemic strokes account for about 87 percent of all strokes, according to the Stroke Association, and the incidence of strokes among younger people and women is rising.

Yepes' doctors credit her sudden creativity for her diagnosis.

She is now recovering at home, and is taking cholesterol-lowering and blood-thinning medication, according to CBC.
