INTRODUCTION: The coronavirus disease 2019 (COVID-19) caused a collapse situation in many hospitals around the world The aim of this study is to analyse the utility of the electroencephalogram (EEG) in the management of the neurological patient during the COVID-19 pandemic PATIENTS AND METHODS: The Clinical Neurophysiology Department of the Hospital Central de la Defensa Gomez Ulla was dissolved due to the hospital collapse situation Therefore, the EEG was performed exceptionally in those cases with the greatest probability of providing a benefit in its management We describe seven patients (four in ICU and three hospitalized) diagnosed with COVID-19, who underwent through an EEG RESULTS: The EEG showed abnormalities in all cases, including one case of brain death The EEG resulted in a change in clinical management in four of the patients (57%) and helped the clinician provide information to the family In the other three cases, a toxic-metabolic origin was suspected before the EEG was performed, so it did not imply a change in the clinical management already proposed, although it facilitated a prognostic orientation Slow polymorphic waves were evident in five cases Five patients were unresponsive Currently, one patient remain hospitalized and four have died CONCLUSIONS: The EEG was useful and facilitated decision making in COVID-19 patients in whom it was requested It guided the diagnosis in cases where CT was non-contributory and led to a change in therapeutic management in most patients The most frequent findings were signs of encephalopathy and epileptiform discharges
