Neurological Manifestations and Their Effect on Outcome in Second Wave of COVID-19 Pandemic: A Retrospective Cohort Study

Abstract

Aim: There is a need for a better understanding of the relation of various neurological symptoms and complications with manifestations and outcomes of coronavirus disease 2019 (COVID-19). Hence, we planned this study to get an insight into the relation of neurological manifestations and COVID-19.

Materials and methods: This was a retrospective study. All patients ≥18 years in age, admitted with reverse transcription-polymerase chain reaction (RT-PCR) confirmed COVID-19 were included in the study. Their clinical records were accessed for collecting demographic and laboratory data. The data collected were analyzed for prevalence and pattern of neurological symptoms at admission and neurological complications developed during hospitalization. It was also analyzed to find the relation of neurological manifestations with duration of hospital stay, requirement of bilevel positive airway pressure (BiPAP) or ventilator, severity of disease, development of neurological complications, and mortality.

Results: A total of 440 patients were included. The mean age was 59.28 ± 13.28 years. The most common neurological symptom at presentation was headache while the most common neurological complications were altered sensorium, cerebrovascular stroke, seizure, and encephalitis. Significantly, more patients with neurological complications than those without had severe disease and needed ventilation. Duration of hospitalization was significantly longer (16.26 ± 5.15 vs 12.73 ± 4.89, p = 0.0173) and mortality was also significantly higher (OR 6.59, 95% CI 2.23-19.43; p = 0.0006) in patients with neurological manifestations.

Conclusion: The presence of neurological manifestations is associated with greater morbidity and mortality in patients with COVID-19 and thus warrants more aggressive treatment. However, a study of association of individual neurological manifestation with severity of COVID-19 will provide a more meaningful insight regarding the approach to the management of such patients.
