            cells by the angiotensin-converting
            enzyme 2 receptor (ACE2r), which
            has little expression in the brain.
            There has been hypotesis that
            other  routes  of  CNS  infi ltration
            might account for the respiratory
            failure caused by infection with
            SARS-CoV-2, although there isn’t,
            actually, evidence.There is prelimi-
            nary  in-vitro evidence that  SARS-
            CoV-2 can replicate in neuronal cel-

            to in-vivo settings remains unclear.

            cause sustained mental morbidity.
