Since the start of the COVID-19 pandemic, researchers have been working to better understand and characterize the varied symptoms of the disease. One of the most concerning symptoms is the development of large blood clots that can cause blockages in the arteries that lead to the brain causing stroke.

Researchers at Western University and Lawson Health Research Institute led by Dr. Luciano Sposato have been investigating the relationship between COVID-19 and stroke to better understand the risk in patients and aid in treatment planning. In a new study published in the September 15, 2020 online issue of Neurology, the medical journal of the American Academy of Neurology, the research team reports that approximately two in every 100 patients admitted to hospital with COVID-19 will suffer a stroke, and 35 per cent will die as a result of both conditions.
