This multi-center collaborative grant (Weill Cornell, Columbia, Massachusetts General Hospital) The three centers are collecting and organize data from Covid-19 patients in New York City and in Boston (another US epicenter) at the Massachusetts General Hospital. The teams at each location have been collaborating over several years under JSMF grants studying recovery of consciousness following structural brain injuries and mechanisms underlying surgical anesthesia. This proposal is focused on the identification of factors improving the care and treatment of Covid-19 patients who develop disorders of consciousness.
