Neurological manifestations as prognostic factors in COVID-19: a retrospective cohort study.

Background: Neurological manifestations are frequent during COVID-19 but have been poorly studied as prognostic markers of COVID-19.

Objectives: The aim of this study was to assess whether neurological manifestations are associated with a poor prognosis of COVID-19, and which patient and COVID-19 characteristics were associated with encephalopathy.

Methods: This was a retrospective cohort study and included patients admitted with COVID-19 in four hospitals from Recife, Brazil.
