Hypersomnia secondary to severe acute respiratory syndrome coronavirus-2 infection

Excessive daytime sleepiness (EDS), with or without an excessive need for sleep, is a primary reason for patients seeking consultation at the sleep unit. EDS is observed in ~5% of the general population. Common causes of EDS include obstructive sleep apnea, sleep deprivation, effects of medication, psychiatric disease (especially depression), and circadian rhythm disorders. Coronavirus disease 2019 (COVID-19) infection is a rare cause of EDS. We present a case of mild COVID-19 infection as an unusual cause of hypersomnolence.
