Researchers at Western University's Schulich School of Medicine and Dentistry released a new study Tuesday that expands on the connection between COVID-19 and strokes.

 The team found about two per cent of patients admitted to hospital with COVID-19 will suffer a stroke. And 35 per cent of those individuals will die as a result of both conditions. 

One of the most concerning symptoms of COVID-19, researchers report, is the development of large blood clots that can block arteries leading to the brain, causing a stroke. 

Researchers also found that in patients younger than 50 years old, nearly half had no other visible symptoms of the novel coronavirus at the time of the stroke. 

"One of the most eye-opening findings of the study is that for patients under 50 years old, many were totally asymptomatic when they had a stroke related to COVID-19," Luciano Sposato, who holds the stroke research chair at the school, said in a news release."This means that for these patients, the stroke was their first symptom of the disease." 

"The take-home message here for health care providers is that if you are seeing a patient with a stroke, particularly in those under 50 years old with large clots, you need to think of COVID-19 as a potential cause even in the absence of respiratory symptoms," he added.
