As the COVID-19 patients increased, the researchers and medical practitioners are doing their best effort to formulate and produce the vaccine that the world has been longing and waiting for. As the fatality increases, new breeds of symptoms are summing up and evolving worst than everyone could imagine. Aside from the symptomatic and asymptomatic pattern, the virus continuously emerged and evolved.
According to researchers, less than 1% of patients who are admitted with COVID-19 suffer a stroke. But they also found out in their recent study that people with COVID-19 who suffer a stroke are seven times more likely to die than people who have a stroke but aren’t infected with COVID-19. Sounds deadly, isn’t it?
Dr. Shadi Yaghi, an assistant professor in the department of neurology at NYU Grossman School of Medicine in New York City said in the interview with the NY News, “Our study suggests that stroke is an uncommon yet important complication of coronavirus, given that these strokes are more severe when compared with strokes occurring in patients who tested negative for the virus,” lead researcher For the study, Yaghi and his team identified 32 stroke patients among more than 3,500 being treated for COVID-19 at NYU hospitals between March 15 and April 19.
A comparison with the data with COVID patients hospitalized with stroke than the stroke patients who are not infected. They compared these patients with stroke patients without the virus. The researchers found that stroke patients with COVID-19 had more severe symptoms than those without the virus. During the study period, 63% died, compared with 9% of those without the virus and 5% of those who had a stroke before the pandemic.
These findings add to the evidence that COVID-19 is associated with an increased risk for clotting, which can trigger a stroke, the researchers said.
“Our findings provide compelling evidence that widespread blood-clotting may be an important factor that is leading to stroke in patients with COVID-19.” said study co-author Dr. Jennifer Frontera, a professor in the department of neurology at NYU.
“The results point to anticoagulant, or blood thinner therapy, as a potential means of reducing the unusual severity of strokes in people with the coronavirus,” Frontera added in the release.
Although typically considered a lung infection, COVID-19 has been found to cause blood clots that can lead to severe stroke.
Experts say that this can happen in any patients regardless of age, and even in those with few or no symptoms.
People with COVID-19 as young as 30 are experiencing strokes even when their symptoms were mild.

COVID-19, the disease caused by SARS-CoV-2, usually attacks the lungs. It causes symptoms that include cough and difficulty breathing — but doctors are noticing a disturbing trend.
People as young as 30 are experiencing strokes, even when their symptoms were mild.
“The coronavirus has been shown to cause development of microthrombi [small clots]. These clots can travel to the lung and obstruct blood flow to the lung, which is called pulmonary embolism, or travel to brain circulation and cause ischemic stroke,” Dr. Theresa Capriotti, DO, MSN, RN, at Villanova University, told Healthline.
“It seems to be happening to those affected with severe COVID symptoms,” Capriotti said. “It can occur in any age group and it occurs suddenly.”
Symptoms to watch out for include:
- weakness or paralysis of the extremities on one side of the body
- lack of sensation in extremities on one side of the body
- facial droop on one side of the face
- speech impairment
When doctors like Dr. Johanna T. Fifi at Mount Sinai saw unusual numbers of stroke patients with COVID-19 in March, she and colleagues decided to sound the alarm.
“We’re hypothesizing that the virus is having an effect on the lining of the blood vessels all through the body — and that is what is leading to the clots,” she said.
Their report was published in the New England Journal of Medicine (NEJM).
“We published that report because that was a little bit unusual to see so many young patients in such a short period of time,” said Fifi. “But we have some other research looking at our overall numbers, and we saw about double the amount of large vessel strokeTrusted Source than normal during the peak weeks of COVID.”
She confirmed it’s very likely these blood clots are COVID-19-related, and added that it can occur in any age group and can occur suddenly.
“It’s definitely something that it’s [COVID-19] doing, it seems too strong of an association to be unrelated at all, it’s just too much of a coincidence,” said Fifi. “What we know is that COVID is causing blood vessel blockages in other regions, the legs for instance, and COVID is damaging the blood vessel lining throughout the body.”
Severe cases and those with mild or no symptoms
According to Dr. Christopher P. Kellner, professor of neurosurgery at Mount Sinai, the kind of stroke that’s happening is severe stroke — meaning the patients had a large blood clot attach to one of the large arteries in the brain.
“We do know that COVID can increase your chance of developing blood clots if you have severe COVID. Especially if you’re old; older people are more likely to have severe COVID,” he said.
Kellner explained this is why in April, Mount Sinai implemented a plan to give anticoagulant drugs to people with COVID-19. “The reason this is important is we observed this happening in younger patients with no or mild symptoms.”
However, he emphasized “no one recommends that yet for patients at home, with mild disease. But we’re still figuring out the disease and what makes sense to do.”
