COVID-19 and clinical neuropsychology: A review of neuropsychological literature on acute and chronic pulmonary disease.

The illness resulting from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), better known as COVID-19, has quickly escalated to a worldwide pandemic. Although understanding of the short and long-term manifestations of COVID-19 remains incomplete, there is a preponderance of respiratory pathology in COVID-19 and potential for chronic loss of pulmonary function in recovered patients, raising concerns for associated cognitive impacts. We conducted a narrative review of the existing literature on neuropsychological variables in acute/severe respiratory disease and various forms of chronic pulmonary disease to inform expectations about potential cognitive manifestations of COVID-19. Cognitive dysfunction is common but not inevitable in acute and chronic pulmonary disease, although unique predictors and symptom trajectories appear to be associated with each. Although the full scope of neuropathophysiology associated with COVID-19 remains to be established, pulmonary insults associated with the disease are likely to produce cognitive dysfunction in a substantial percentage of patients.
