Patients were stratified into a younger (under 60) group and an older (over 60) group, and symptoms were clustered into broader clinical syndromes associated with COVID-19 and classified into case definitions, including ‘Cerebrovascular event (abnormalities of the blood flow in the brain)’, ‘Altered Mental Status’, ‘Peripheral Neurology’, and ‘Encephalitis’. Members of these professional organizations identified patients exhibiting these syndromes and a swift 5-minute clinical dataset was completed. It contained four critical components: diagnosis of COVID-19, demography, geography, and nature of the clinical syndrome.
