COVID-19 EEG Studies: The Other Coronavirus Spikes We Need to Worry About

Commentary, originally published in Epilepsy Currents

By now it is well-known that neurological manifestations occur in ?35% of COVID-19 patients, and potentially in a majority of patients with more severe infections. Results of electroencephalogram (EEG) in these patients are of particular interest: How frequently is epileptiform activity seen in this patient population, and are the underlying risks for epileptiform activity different from other critically ill patients? Are there novel EEG features specific to COVID-19? Is the EEG informative in guiding the understanding of the pathophysiology of the frequently observed altered mental status, or prognosis, in COVID-19?

We are now starting to see the early COVID-19 EEG studies in the literature.

The 3 papers included in this collection are peer-reviewed studies that systematically assessed EEGs in patients with COVID-19, as of July 26, 2020. That the study authors, clinicians engaged in the momentous task of treating these patients in high prevalence hospitals, were able to quickly disseminate this information is a noteworthy and commendable achievement.
