Objective: To report three patients infected with COVID-19 with severe respiratory syndrome requiring intubation, who developed acute demyelinating encephalomyelitis (ADEM). Method: Patient data were obtained from medical records from the North Memorial Health Hospital, Robbinsdale, MN, USA Results: Three patients (two men and one woman, aged 38 - 63) presented with fatigue, cough and fever leading to development of acute respiratory distress syndrome secondary to COVID-19 infection requiring intubation and ventilatory support. Two patients were unresponsive, one with strong eye deviation to the left and the third patient had severe diffuse weakness. MRI in all patients showed findings consistent with ADEM. CSF showed elevated protein in all patients with normal cell count and no evidence of infection, including negative COVID-19 PCR. All three of the patients received Convalescent plasma therapy for COVID-19. All patients were treated with intravenous corticosteroids and improved, although two responded minimally. Two patients treated with IVIG showed no further improvement. Conclusion: Neurological complications from COVID-19 are being rapidly recognized. Our three cases highlight the occurrence of ADEM as a postinfectious/immune mediated complication of COVID-19 infection, which may be responsive to corticosteroid treatment. Early recognition of this complication and treatment is important to avoid long term complications.
