COVID-19 hospitalization has been linked to long-term brain impairment, with the severity of the illness and hospitalization being key factors. A Danish study published in JAMA Network Open found that COVID-19 patients experienced neurological and psychiatric impairments, including sleep, executive function, memory, and cognitive symptoms. Other studies suggest that COVID-19 contributes to cognitive decline, with patients hospitalized with COVID-19 experiencing cognitive decline equivalent to losing 10 IQ points.
