A trip to a local county fair ended with a young woman developing a stroke and being rushed to the hospital after going on a new ride.
Halfway through the ride, which swings fairgoers rapidly in circles, the 37-year-old woman started to develop a headache and lost coordination of the muscles on the right side of her body. She also started to walk clumsily, due to the loss of muscle control.
Her husband immediately rushed her to the emergency department, where she was diagnosed with vertigo — a condition in which problems with the inner ear or part of the brain cause dizziness — and sent home with a prescription for anti-nausea drugs. However, two days later her symptoms persisted and she was taken back to hospital.
Doctors involved in the case, published Aug. 26 in the journal Cureus, found that her heart rate and breathing rate had soared, and her blood pressure, which was already historically high, was also extremely elevated. They took a computed tomography (CT) scan of her brain that revealed that she had an area of dead tissue near an artery that supplies the right side of the cerebellum, part of the brain that regulates muscle movements and controls balance. This suggested that she'd had a stroke.
Strokes are the fifth leading cause of death in the U.S. and occur when blood flow to the brain is interrupted, depriving tissues of oxygen and causing them to die. Risk factors include having high blood pressure, obesity, smoking and having an inactive lifestyle. In this case, the woman had a 10-year history of smoking a pack of cigarettes a day, and she had untreated high blood pressure.
Doctors couldn't find the exact source of the woman's stroke, although they suspected it was caused by an embolism, in which an artery is blocked by a blood clot that traveled from another part of the body. They prescribed her medications to control her post-stroke headaches and reduce her risk of developing heart disease, and her status was tracked through physical therapy follow-up appointments.
Over the next month, the woman didn't report any new symptoms of stroke and said she'd quit smoking. However, her coordination had worsened. A magnetic resonance imaging (MRI) scan of her brain showed no evidence of another stroke, but six months later, a scan of her head and neck revealed a bulge in the wall of an artery that supplies the right side of her cerebellum. The artery hadn't yet ruptured, but needed to be closely monitored, doctors concluded.
Based on previous cases of people having strokes on rollercoasters and other amusement park rides, the report authors suggest that hyperextension of the neck and tearing of blood vessels may lead to ride-induced strokes. Rides commonly display health warnings, for example, for people with high blood pressure, certain heart conditions and those who are pregnant. However, it is rare to see signs highlighting potential neurological risks, they wrote.
"Healthcare providers need to be vigilant in identifying and managing these cases, and further research on specific risk factors in young individuals is crucial to improving prevention and safety measures in amusement park settings," they concluded.
