Scientists have found that people who contract Covid are at greater risk of brain damage one year after infection than those who don’t have the virus.
American researchers have said that strokes, seizures, memory problems and movement disorders are among the problems suffered by patients after the virus.
According to researchers from Washington University School of Medicine in St Louis.
The year-long study, published in natural medicineanalyzed 44 brain disorders using the medical records of millions of US veterans.
The scientists said their findings translated to about 6.6 million Americans suffering from brain disorders linked to Covid infections.
“The results show the devastating long-term effects of Covid-19,” said lead author Dr. Ziyad Al-Aly of the University of Washington School of Medicine. said in a press release.
The researchers analyzed the medical records of 154,000 American veterans who tested positive for Covid from March 1, 2020 to January 15, 2021.
They compared these records with those of 5.6 million patients who did not have Covid during the same period and 5.8 million people just before Covid arrived in the United States.
The study found that memory impairment, often referred to as brain fog, was the most common symptom in people who contracted the virus.
People who contracted Covid had a 77% higher risk of having memory problems, the study found.
Those with Covid were 80% more likely to have seizures, 43% more likely to have mental health issues such as depression or anxiety, and 35% more likely to have headaches.
They were also 42% more likely to experience movement problems, such as tremors, compared to the control group.
“Given the colossal scale of the pandemic, addressing these challenges requires urgent and coordinated – but so far absent – response strategies at global, national and regional levels,” Al-Aly said.
