Continuous EEG findings in patients with COVID‐19 infection admitted to a New York academic hospital system
Epilepsia Sep 07, 2020
Pellinen J, Carroll E, Friedman D, et al. - Researchers sought to report on the prevalence of seizures and other electroencephalography (EEG) abnormalities among COVID‐19‐infected patients. They reviewed medical records and EEG studies of 111 patients who were hospitalized with confirmed COVID‐19 infections over a 2‐month period at a single US academic health system (four hospitals). Excluding 11 patients monitored after cardiac arrest, moderate generalized slowing was the most frequently identified EEG finding (57%); epileptiform findings were noted in 30% and seizures in 7% (4% with NCS). In support of growing evidence, this study suggests the effect of COVID‐19 on the central nervous system, although seizures did not appear to be the common cause of encephalopathy. Infrequent occurrence of seizures and epileptiform activity on EEG was observed. Only having epilepsy or seizure(s) prior to EEG was independently correlated with epileptiform EEG findings. This has significant implications for prioritizing EEG testing in this population.
