Large study finds higher burden of acute brain dysfunction for COVID-19 ICU patients

Media release:

COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. Choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients.

That’s according to an international study published Jan. 8 in The Lancet Respiratory Medicine, led by researchers at Vanderbilt University Medical Center in coordination with researchers in Spain.

The study, which is far the largest of its kind to date, tracks the incidence of delirium and coma in 2,088 COVID-19 patients admitted before April 28, 2020, to 69 adult intensive care units across 14 countries.

Neurologic complications common even in moderate COVID-19 cases

MINNEAPOLIS – COVID-19 can lead to a broad range of neurologic complications including stroke, seizures, movement disorders, inflammatory diseases and more, even in moderate cases, according to a new study published in the December 9, 2020, online issue of Neurology┬« Clinical Practice, an official journal of the American Academy of Neurology.

“We looked at people with neurologic symptoms and COVID at a racially and socioeconomically diverse hospital and found a wide range of neurologic complications–spanning inflammatory complications, stroke and other vascular conditions, metabolic problems, exacerbation of underlying neurologic conditions and more,” said study author Pria Anand, M.D. of Boston University School of Medicine in Massachusetts and a member of the American Academy of Neurology. “Yet the majority of these people did not require critical care, suggesting that neurologic complications may be common in people with moderate COVID-19 as well as those with severe disease.”
