ABSTRACT

Neurological symptoms are increasingly recognized in SARS-CoV-2 infected individuals. However, the neuropathogenesis remains unclear and it is not possible to define a specific damage pattern due to brain virus infection. In the present study, 33 cases of brain autopsies performed during the first (February-April 2020) and the second/third (November 2020-April 2021) pandemic waves are described. In all the cases, SARS-CoV-2 RNA was searched. Pathological findings are described and compared with those presently published.

ABSTRACT

Encephalopathy is emerging as a recurrent complication of COVID-19 yet remains poorly characterized. We report the case of a middle-aged woman with COVID-19-related encephalopathy presenting as expressive aphasia and inattentiveness, subsequently progressing to agitation and marked confusion. Brain MRI and CSF analysis were unremarkable, while EEG showed slowing with frontal sharp waves. Neuropsychiatric symptoms resolved following treatment with tocilizumab. CNS involvement in COVID-19 may present as a subacute encephalopathy characterized by prominent frontal lobe dysfunction, with language disturbances as first neurological manifestation. Future studies should further investigate the role of tocilizumab in treating COVID-19-related encephalopathy.
