Emerging research suggests that a sizeable portion of individuals hospitalized due to COVID-19 develop cognitive and psychological sequelae. In our conversation with Dr. Chaya Fridman, a board-certified neuropsychologist at Cornell, we discuss the ways that SARS-CoV-2 (the virus that causes COVID-19) may lead to neurocognitive impairment, including both direct effects of the virus and secondary factors (e.g., respiratory distress and treatments used in the Intensive Care Unit). We review how the virus gains access to the central nervous system and the potential underlying mechanisms by which it causes an increased risk of stroke and other neurological issues. We also examine the long-term effects of prior coronaviruses (SARS-CoV and MERS-CoV) to attempt to forecast the long-term effects of COVID-19, with a focus on how neuropsychological practice (both inpatient and outpatient) might be affected.
