Study reports 13% of hospitalizations for COVID-19 with severe neurological symptoms

According to a study that analyzed data from 16,225 patients in 24 countries, about 13% of patients hospitalized for COVID-19 developed severe neurological symptoms during the first year of the pandemic.

Led by Boston University and published this Wednesday (4) by the journal Critical Care Exploration, it aims to describe the prevalence, associated risk factors and outcome of severe neurological manifestations in patients hospitalized with COVID.

Sars-CoV-2 has been shown to cause dysfunction of several organ systems, including the nervous system, and neurological symptoms “frequently” occur even in patients with mild symptoms, and in some people they continue as part of persistent COVID-19. can stay.

The team studied 16,225 patients from 179 hospitals in 24 countries and found that about 13% of those admitted in the first year of the pandemic developed severe neurological manifestations.


The data showed that 1,656 (10.2%) had encephalopathy (any diffuse disease of the brain that alters brain function or structure) at the time of admission; 331 (2%) had a stroke; 243 (1.5%) had seizures; and 73 (0.5%) had meningitis or encephalitis at admission or at hospitalization.

“Our findings suggest that inpatient encephalopathy is present in at least one in ten patients with SARS-CoV-2 infection, whereas stroke, seizures and meningitis/encephalitis were much less common,” said one of the study’s authors, Anna Cervantes-Arslanian explained. Boston University.

All severe neurological manifestations were associated with greater disease severity, greater need for ICU intervention, longer hospital stay, use of respirators, and higher mortality.

Patients with neurological manifestations were more likely to have a medical comorbidity, particularly a history of stroke or neurological disorders, which increase the risk of developing neurological manifestations.

Anna Cervantes said that, given the association of neurological manifestations with poor outcomes, “more studies are urgently needed” to understand why these differences occur and how to intervene.
