Former COVID patients have a higher risk of long-term brain damage, according to a year-long study published Thursday in Nature Medicine. The team, led by Dr. Ziyad Al-Aly of the Washington University School of Medicine and the Veterans Affairs St. Louis Health Care System, reviewed the anonymized medical records of millions of veterans and found that neurological disorders occur produced in 7% more of those who had already been infected with COVID compared to those who had not. The researchers looked at 154,000 U.S. veterans who tested positive for COVID from March 1, 2020 through January 15, 2021. These records were compared to 5.6 million patients who did not test positive for COVID and 5.8 million records shortly before the pandemic hit the United States. The most common neurological disorder was memory problems, commonly referred to as “brain fog.” The infected group showed a 77% higher risk of developing brain fog compared to the control group. depression (43%), headaches (35%) and movement disorders such as tremors (42%). Earlier this year, Al-Aly and his colleagues also published a study showing that vaccines were less effective in preventing long COVIDs than previously thought. This study also relied on millions of veterans’ medical records. Unlike this study, this study was not aimed at long COVID patients, but instead focused on patients with COVID whether or not they had long COVID symptoms. This potentially shows that COVID infection can have long-term health consequences, even after symptoms resolve. Al-Aly says governments must prepare for the strain COVID will have on our health systems and society at large. “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,” he said.
