Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.
Neurological Manifestations of SARS-CoV-2 in Hospitalized Children: A Multi-National Cohort Study

Background: Knowledge about neurological manifestations of SARS-CoV-2 in children is limited. We describe neurological manifestations in an international cohort of hospitalized pediatric patients.
Methods: This is a multi-national observational study involving tertiary healthcare institutions in Canada, Costa Rica and Iran. We included patients 1 day-18 years admitted for any medical reason February 1, 2020-January 31, 2021 with laboratory evidence of SARS-CoV-2 infection by RT-PCR or serological testing. Descriptive analyses and logistic regression were performed where appropriate using JASP version 0⋅13.
Findings: 298 hospitalized children with confirmed SARS-CoV-2 infection (median age 3⋅9 years [IQR 0⋅6-10⋅1]) from Canada (n=152), Costa Rica (n=115) and Iran (n=31) were included. Fifty-one (17%) had neurological manifestations, of which headache (73%), seizures (23%) and altered mental status (6%) were most frequently seen. Children with neurological symptoms had equivalent rates of comorbidities overall but were more likely to have underlying chronic neurological conditions. Additionally, those with neurological symptoms were more likely to be admitted to the ICU (15/51 [29%] vs. 32/247 [13%]; p =0⋅0033) and had longer length of hospital stay (6 days [IQR 3-8] vs. 4 days [IQR 2-7]; p =0⋅0060). Abnormalities were found in all children with neurological manifestations who received neuroimaging (n=6). Neurological manifestations were seen in 19% of the Iranian cohort, 23% of the Costa Rican cohort, and 12% of the Canadian cohort. Country of residence Costa Rica (adjusted OR: 2⋅520, 95% CI: 1⋅325-4⋅791, p =0⋅005), ICU admission (adjusted OR: 2⋅678, 95% CI: 1⋅307-5⋅486, p =0⋅007) and number of acute SARS-CoV-2 infection symptoms (adjusted OR: 1⋅355, 95% CI: 1⋅232-1⋅491, p <0⋅0001) were independently associated with neurological manifestations using multivariate analysis.
Interpretation: We show that children with underlying comorbidities, especially underlying neurological diagnoses, are more likely to develop neurological complications of SARS CoV-2, and that sociodemographic factors, such as country of residence associate with varying rates of neurological manifestations. Future studies should focus on long-term outcomes in these children.
