"We are learning that a significant number of hospitalized COVID-19 patients have various degrees of brain impairment. As a medical community, we need to monitor these patients over time as some of them may develop cognitive decline, attention deficit, brain fog, or Alzheimer's disease in the future. There is a lot we can do to promote brain healing in COVID-19 patients, but first we must understand the nature and severity of their neurological deficits. At the patient level, getting a baseline MRI before leaving the hospital is imperative so that we have a starting point to evaluate and treat them," explained Fotuhi.
