ObjectiveTo report clinical and laboratory characteristics, as well as treatment and clinical outcomes of patients admitted for neurologic diseases with and without COVID-19.MethodsIn this retrospective, single center cohort study, we included all adult inpatients with confirmed COVID-19, admitted to a Neuro-COVID Unit from February 21, 2020, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records and compared (FDR-corrected) to those of neurologic patients without COVID-19 admitted in the same period.ResultsOne hundred seventy-three patients were included in this study, of whom 56 were positive for COVID-19 while 117 were negative for COVID-19. Patients with COVID-19 were older (77.0, IQR 67.0–83.8 vs 70.1, IQR 52.9–78.6, p = 0.006), had a different distribution regarding admission diagnoses, including cerebrovascular disorders (n = 43, 76.8% vs n = 68, 58.1%), and had a higher quick Sequential Organ Failure Assessment (qSOFA) score on admission (0.5, IQR 0.4–0.6 vs 0.9, IQR 0.7–1.1, p = 0.006). In-hospital mortality rates (n = 21, 37.5% vs n = 5, 4.3%, p < 0.001) and incident delirium (n = 15, 26.8% vs n = 9, 7.7%, p = 0.003) were significantly higher in the COVID-19 group. COVID-19 and non-COVID patients with stroke had similar baseline characteristics but patients with COVID-19 had higher modified Rankin scale scores at discharge (5.0, IQR 2.0–6.0 vs 2.0, IQR 1.0–3.0, p < 0.001), with a significantly lower number of patients with a good outcome (n = 11, 25.6% vs n = 48, 70.6%, p < 0.001). In patients with COVID-19, multivariable regressions showed increasing odds of in-hospital death associated with higher qSOFA scores (OR 4.47, 95% CI 1.21–16.5; p = 0.025), lower platelet count (0.98, 0.97–0.99; p = 0.005) and higher lactate dehydrogenase (1.01, 1.00–1.03; p = 0.009) on admission.ConclusionsCOVID-19 patients admitted with neurologic disease, including stroke, have a significantly higher in-hospital mortality, incident delirium and higher disability than patients without COVID-19.
Background Clinical investigations have argued for long-term neurological manifestations in both hospitalised and non-hospitalised COVID-19 patients. It is unclear whether long-term neurological symptoms and features depend on COVID-19 severity. Methods From a sample of 208 consecutive non-neurological patients hospitalised for COVID-19 disease, 165 survivors were re-assessed at 6 months according to a structured standardised clinical protocol. Prevalence and predictors of long-term neurological manifestations were evaluated using multivariate logistic regression analyses. Results At 6-month follow-up after hospitalisation due to COVID-19 disease, patients displayed a wide array of symptoms; fatigue (34%), memory/attention (31%) and sleep disorders (30%) were the most frequent. At neurological examination, 40% of patients exhibited neurological abnormalities, such as hyposmia (18.0%), cognitive deficits (17.5%), postural tremor (13.8%) and subtle motor/sensory deficits (7.6%). Older age, premorbid comorbidities and severity of COVID-19 were independent predictors of neurological manifestations in logistic regression analyses. Conclusions Premorbid vulnerability and severity of SARS-CoV-2 infection impact on prevalence and severity of long-term neurological manifestations.

BackgroundPreclinical and clinical investigations have argued for nervous system involvement in SARS-CoV-2 infection and for long term sequalae including neurological manifestationsMethodsa sample of 208 previously hospitalized COVID-19 patients, 165 patients were re-assessed at 6 months according to a structured standardized clinical protocol. Premorbid comorbidities and clinical status, severity of COVID-19 disease, complications during and after hospitalization were recorded.ResultsAt 6-month follow-up after hospitalisation due to COVID-19 disease, patients displayed a wide array of neurological symptoms, being fatigue (34%), memory/attention (31%), and sleep disorders (30%) the most frequent. Subjects reporting neurological symptoms were affected by more severe respiratory SARS-CoV-2 infection parameters during hospitalisation. At neurological examination, 37.4% of patients exhibited neurological abnormalities, being cognitive deficits (17.5%), hyposmia (15.7%) and postural tremor (13.8%) the most common. Patients with cognitive deficits at follow-up were comparable for age, sex and pre-admission comorbidities but experienced worse respiratory SARS-CoV-2 infection disease and longer hospitalisation.Conclusionslong term neurological manifestations after hospitalization due to COVID-19 infection affects one third of survivors. Multiple neurological abnormalities including mild cognitive impairment are associated with severity of respiratory SARS-CoV-2 infection.
