Abstract
SARS-CoV-2 responsible for Covid-19, although having a primary pulmonary tropism, also causes variable neurological damage that it is important to know. In this narrative review, after briefly recalling the particularities of SARS-CoV-2 infection in the elderly, the authors present the main hypotheses that explain the neurotropism of SARS-CoV-2, the main types of neurological damage and the possible interactions with Parkinson's disease and Alzheimer's disease.
