Science has already demonstrated that Covid-19 attacks our brain, and more specifically our central nervous system. Some symptoms like loss of taste and smell prove it. They would reflect the ability of the coronavirus to attack our nervous system, by damaging the areas processing olfactory information (relating to the sense of smell).
Over time, many neurological symptoms have appeared in Covid patients. This was particularly the case in people affected by the syndrome called Covid long. “The ‘long Covid’ is defined by the presence of symptoms which last more than three months after an acute infection with Sars-CoV-2”, explains the Government.
A news study published on June 15, 2022 within theAnnals of Clinical and Translational Neurology revealed the prevalence of neurological symptoms that would last more than six months in some patients.
Covid: two thirds of patients have persistent neurological symptoms
Researchers from the Faculty of Medicine at the University of California, San Diego (USA) conducted their research on 56 people with neurological symptoms. They were asked to complete a neurological examination, cognitive assessment, self-report questionnaires and an optional brain scan.
Of these patients, 89% of participants were still experiencing their neurological symptoms 3 months after their Covid-19 infection. At the end of six monthsonly a third reported complete resolution of symptoms.
The other two-thirds of participants reported persistent neurological symptoms, although most decreased in severity.
The researchers point out that none of them hadbackground pre-existing neurological disorders before Covid contamination.
“It’s encouraging that most people were showing some improvement at six months, but that wasn’t the case for everyone,” said lead author Jennifer S. Graves, MD, PhD, professor fellow at UC San Diego School of Medicine and neurologist at UC. San Diego Health.
