Patients with severe coronavirus disease 2019 (COVID-19) disease suffer from many thrombotic complications including deep vein thrombosis, pulmonary embolism, myocardial infarction (MI), and stroke. Large vessel strokes have been reported in young patients with COVID-19 disease. We report four cases of stroke diagnosed based on CT scan in critically ill individuals treated in the medical intensive care unit in a health facility in New York. All patients were receiving supportive treatment and mechanical ventilation at the time of diagnosis. All patients had impaired consciousness and were unable to wake up after sedation had worn off, prompting further workup. The pathogenesis of stroke could be secondary to the embolic phenomenon vs. hypercoagulopathy in our patients. Stroke should be considered in all COVID-19 patients who present with altered mental status. Severe COVID-19 patients with risk factors of stroke may benefit from therapeutic anticoagulation.
