COVID-19 increases risk of long-term brain injury: Study

US researchers reported Thursday that people who had COVID-19 had a higher risk of a series of brain injuries a year later than those who had never been infected with the coronavirus, a finding that could affect millions of people. can do

The year-long study, published in Nature Medicine, assessed brain health in 44 different disorders using medical records without patient identifiers from millions of American veterans.

Neurological disorders and other neurological disorders were 7% higher in people who were infected with COVID compared to the same group of the elderly who had never been infected.

The team said that about 6.6 million Americans have neurological disorders associated with their COVID-19 infection.

“The results show the devastating long-term effects of COVID-19,” lead author Dr. Ziad al-Ali from the University of Washington School of Medicine said in a statement.

Al-Ali and colleagues from the Washington University School of Medicine and the St. Louis Veterans Affairs Health Care System studied the medical records of 154,000 US veterans who tested positive for COVID from June 1, 2020 to January 15, 2021.

They compared these with records from 5.6 million non-Covid patients during the same time period, and with another group of 5.8 million people from the period just before the arrival of the coronavirus in the United States.

Al-Aly pointed out that previous studies looked at a small group of disorders and mostly focused on hospitalized patients, while theirs included both hospitalizations and outpatients.

Memory disorders, commonly known as brain fog, were the most common symptoms. Compared to the control groups, people infected with COVID had a 77% increased risk of developing memory problems.

People infected with the virus were 50% more likely to have an ischemic stroke caused by blood clots than the uninfected group.

People infected with COVID were 80% more likely to have seizures, 43% more likely to have mental health problems such as anxiety or depression, 35% more likely to have headaches, and 42% more likely to have mood disorders. tremors compared to control groups.

“Given the sheer scale of the pandemic, there is a need for urgent and coordinated response strategies, but to address these challenges at the global, national and regional levels are still lacking,” Al-Ali said.
