Abstract
Abstract: As COVID-19 continues to infect millions of people globally, it is essential to understand how SARS-CoV-2 affects the brain. The purpose of this study is to determine if there are any associations or patterns of gross and microscopic neuropathological autopsy findings in the brains of patients who died from COVID-19. We analyzed 32 autopsy cases that met 3 requirements: (1) positive polymerase chain reaction (PCR) SARS-CoV-2 test at autopsy; (2) pulmonary histological features of SARS-CoV-2; (3) complete autopsies conducted during the COVID-19 pandemic from 2020 to 2023. We accounted for the presence of the following gross and microscopic neuropathological findings: cerebral edema (CE), cerebral cortical atrophy (CCA), chronic cerebrovascular disease (CCD), cerebral ischemic injury (CII), cerebral inflammation (CIN), and/or cerebral parenchymal hemorrhage (CPH) in every case. We found that CE, CCA, and CII diagnoses had a statistically significant association with age. There were no distinctive or recurrent neuropathological alterations in the autopsied brains that may be interpreted to be pathognomonic of SARS-CoV-2 infection in our cohort. These findings may suggest that SARS-CoV-2 infection is not associated with any distinct histomorphologic abnormalities that are diagnostic of COVID-19 in the brains of autopsied patients.
期刊介绍:
Drawing on the expertise of leading forensic pathologists, lawyers, and criminologists, The American Journal of Forensic Medicine and Pathology presents up-to-date coverage of forensic medical practices worldwide. Each issue of the journal features original articles on new examination and documentation procedures.
While most articles are available as web based articles, PDF and in ePub reader format, some earlier articles do not have PDFs available. If you would like to view an article in the ePub format, you will need to download an ePub reader to view this file, a number of which are available for free online.
