Neurologic Manifestations in a Prospective Unselected Series of Hospitalized Patients With COVID-19

Background An increasing number of neurologic problems are being described in coronavirus disease 2019 (COVID-19) disease, but their frequency and type have not been defined. In this study, we sought to determine the extent of neurologic manifestations of COVID-19 in a prospective series of unselected patients admitted to the general medicine wards of our hospitals due to COVID-19 and who were examined by a team of neurologists.

Methods Eight neurologists provided medical attention to patients hospitalized for COVID-19 to provide medical support to other hospital units tasked with the care of an increasingly larger influx of patients with COVID-19. A series of 100 consecutive, unselected patients were evaluated systematically, including a questionnaire that collected medical information derived from the initial examination and the medical history.

Results Eighty-eight percent of the patients had 1 neurologic manifestation associated with COVID-19 during hospitalization. Most common were anosmia-dysgeusia and headache (44% each), myalgias (43%), and dizziness (36%). Less frequent were encephalopathy (8%), syncope (7%), seizures (2%), and ischemic stroke during the period of hospitalization (2%). Anosmia and headache associated with younger patients with less severe disease, and both were associated with each other and with serum inflammatory markers. Encephalopathy was associated with fever and syncope and with markers of inflammation.

Conclusions Neurologic disturbances are common in patients with COVID-19, particularly if patients are evaluated by neurologists. There is a wide variety of neurologic conditions, some of them severe, in the spectrum of COVID-19 disease that will benefit from an evaluation by practicing neurologists.
