A new study has found that stroke may be the first symptom of “Covid-19” in younger patients.
The researchers conducted a meta-analysis of data from 10 studies, including 160 patients with “Covid-19″ who had had a stroke, and found that nearly half of the patients under the age of 50 were asymptomatic at the time the stroke appeared.
Lead author Dr Luciano Sposato, Associate Professor and Head of Stroke Research at Western University in Ontario, Canada, said: “One of the most eye-opening findings in this study is that for patients under the age of 50, many of them were completely asymptomatic when They had a stroke related to Covid-19, which means, for these patients, that the stroke was the first symptom of the fatal disease. ”
When “Covid-19” appeared in the world more than eight months ago, medical experts considered it a respiratory disease in the first place. Today, after months of reports that “Covid-19” patients suffer from blood clots, pulmonary embolism and strokes, they say it may also be a vascular disease, meaning that it affects blood vessels.
“In early April 2020, we realized that Covid-19 was a highly coagulant (blood-clotting) disease,” Sposato told Medscape this week, which prompted him and his colleagues to conduct the study.
The study found that 43% of Covid-19 patients under the age of 50 had no previous risk factors for stroke. And 48% of these patients had a stroke before they had any respiratory symptoms of “Covid-19”.
“We should consider Covid-19 a new cause or risk factor for stroke. At the very least, stroke patients are likely to be tested for SARS-CoV-2 infection if they are young and have a large blood vessel blockage,” Sposato noted. In the absence of typical respiratory symptoms of Covid-19 disease.
Why does this happen?
Researchers speculate that the blood clotting that leads to stroke could be the result of an “exaggerated inflammatory response” caused by the new coronavirus.
Covid-19 appears to cause widespread inflammation throughout the body, including the brain, lungs, heart and blood vessels.
In severe cases, this could be fatal and cause a stroke or respiratory failure. Even in mild cases of disease, researchers believe that this inflammation can lead to fatigue, muscle problems, and nerve problems that can last for weeks or months.

“Infections and infections increase the risk of stroke. Covid-19 is an infection that produces a strong inflammatory reaction. It also appears that Covid-19 causes the occurrence,” Dr. Babak Navi, medical director of the Weill Cornell Stroke Center, wrote on the hospital’s website on August 26. Heart attacks. All of these factors can lead to a stroke. Also, Covid-19 causes a serious illness that can lead to the failure of many organs, including kidney failure. Having a serious disease and the failure of many organs can put patients at risk “The last possible explanation is how Covid-19 affects the blood clotting system. It appears to enhance clot formation, as shown by laboratory studies, but we do not know exactly how.”
According to the CDC, signs of a stroke include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, difficulty speaking, or difficulty understanding speech, that is, sudden vision problem, sudden difficulty walking, dizziness, loss of balance or lack of coordination. If you experience any of these symptoms, seek medical help immediately.
