Acute Confusional Syndrome in patients with COVID-19

Abstract

In respiratory failure, SARS-CoV-2 can cause central nervous system (CNS) involvement, including acute confusional syndrome (ACS) or delirium that occurs in critically ill patients. The relationship between COVID-19 and acute confusional syndrome was identified. Through a theoretical review, mainly primary sources of information, specialized databases were used: Scielo, Pubmed, Wiley Online Library, BMJ were used. They were included articles on ACS/delirium in patients with COVID-19, published in indexed journals with impact factor > 2.000; with patients about both sexes; in Spanish or English language; open access; with analytical or observational design; systematic reviews and meta-analyzes. The information was organized in characteristics about studied universe data and their main findings/results in the study. Delirium in patients with COVID-19 has a variable incidence; predominates among older adults, with a history of neurocognitive impairment. Social isolation also plays an important role in its appearance. Delirium caused for SARS-Cov-2 infection; therefore, neuropsychiatric assessment is strongly suggested within the care protocol for hospitalized patients with COVID-19
