Electroencephalogram and neurological manifestations in times of COVID-19. Why and how to do it?
Keywords:
electroencephalogram, seizures, SARS-CoV-2, COVID-19, encephalopathyAbstract
The objective of this study is to review the available evidence on the role of Electroencephalogram (EEG) in the context of the impact of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the central nervous system. The study was based on an exhaustive review of the publications indexed in the National Library of Medicine of the United States of America (Pubmed/Medline). In addressing the neurological complications of SARS-CoV-2 infection, emphasis is placed on reports of epileptic seizures, non-seizure epileptic states, acute symptomatic seizures, and encephalopathies. The EEG findings reported in the literature are detailed. Recommendations for the EEG recording and interpretation are also presented concerning patients under investigation for coronavirus disease 2019 (COVID -19), in both outpatient and hospitalization statuses, emphasizing the Care Intensive Units. It is concluded that EEG provides relevant information for the evaluation of neurological manifestations in patients under investigation for COVID-19. Carrying out the different types of EEG studies requires the assessment of risk versus benefit, and demands compliance with biosafety protocols.Downloads
