Daytime Hypersomnolence in COVID-19: A Case Report and Literature Review

Coronavirus infectious disease 2019 (COVID-19) is confirmed to develop neurocognitive complications. In the present paper, we describe two patients with laboratory-confirmed COVID-19 and excessive daytime sleepiness. In the present study, we reported two laboratory-confirmed cases of COVID-19 with excessive daytime sleepiness. Patients had drowsiness and mild confusion on presentation. In both cases, CNS infections, including meningitis and encephalitis, were ruled out. Both patients’ symptoms remarkably improved following the therapeutic course indicating the direct effect of SARS-CoV2 in sleep modulating centers on the brain. COVID-19 should be considered in patients with excessive daytime sleepiness and drowsiness in the current outbreak.
