Paramedics treated Kowalczyk at home. Initially diagnosing her with a migraine due to her symptoms of dizziness—considered typical after chiropractic treatments—despite negative FAST tests indicating stroke symptoms could have subsided quickly. Her second FAST test also turned out negative. Kowalczyk’s condition worsened significantly over the next 24 hours; paramedics were called again to transport her to Queen Elizabeth Hospital. Tragically, she passed away on October 19, 2021. A post-mortem CT scan revealed an obstruction near the base of her skull and a CT angiogram confirmed a left vertebral artery dissection.
