Neurocognitive Disorders in COVID-19 Patients: Controversed and Unresolved Issues

Abstract

New Coronavirus Infection (COVID-19) is an infectious disease caused by Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2). Since 2019, a large number of studies on cognitive impairment in the background of COVID-19 have emerged, and “long COVID” is among them. A non-systematic review based on 2019-2022 studies provides information on the severity of cognitive changes in patients with COVID-19, diagnostic methods that can detect these cognitive impairment and long-term neuropsychiatric and cognitive outcomes that may pose a serious public health challenge.
