Only one in three patients who became seriously ill with coronavirus do not suffer from neurological symptoms up to six months later, proving that long covid is a condition that needs attention.
Specifically, according to the study published in the Annals of Clinical and Translational Neurology, the most common neurological symptoms were fatigue and headaches (89.3 and 80.4%, respectively) after acute infection. Memory impairment and impaired concentration (68.8 and 61.5%, respectively) were the most prevalent symptoms after six months, although all symptoms showed significant attenuation on average after six months.
The research team from University of California, San Diego examined 56 participants with neurological symptoms (29% with prior neurological disease, such as multiple sclerosis) following acute infection with SARS-CoV-2, the virus that causes coronavirus infection, from October 9, 2020 to October 11, 2021. 27 of them were retested by the scientists 6 months later.
After six months, complete remission of symptoms was observed in 33.3% of participants. Mean cognitive assessment scores improved overall from baseline to six months. Participants' scores decreased to 26.3%. A syndrome with symptoms such as tremor, ataxia and cognitive dysfunction was reported in 7.1% of patients.
"The fact that people's cognitive ability and quality of life are still affected to such an extent so many months after initial infection is something we need to look at closely as a society," say the study authors. "We still need to know how common this phenomenon is, what biological processes cause it and what kind of health care these patients will need."
