Coronavirus Disease 2019-Associated Neurological Manifestations in Children: A Large Single-Center Experience With Rare Cases

Abstract

BackgroundWe aimed to analyze pediatric patients with coronavirus disease 2019 (COVID-19) with a diverse spectrum of neurological manifestations in a single center since neurological involvement in children is still poorly understood. MethodsWe performed a retrospective study on 912 children aged between zero and 18 years who had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test result and symptoms of COVID-19 from March 2020 to March 2021 in a single center. ResultsAmong 912 patients, 37.5% (n = 342) had neurological symptoms and 62.5% (n = 570) had no neurological symptoms. The mean age of patients with neurological symptoms was significantly higher (14.2 ± 3.7 vs 9.9 ± 5.7; P < 0.001). Three hundred and twenty-two patients had nonspecific symptoms (ageusia, anosmia, parosmia, headache, vertigo, myalgia), whereas 20 patients had specific involvement (seizures/febrile infection-related epilepsy syndrome, cranial nerve palsy, Guillain-Barré syndrome and variants, acute disseminated encephalomyelitis, central nervous system vasculitis). The mean age of the patients with nonspecific neurological symptoms was significantly higher (14.6 ± 3.1 vs 7.7 ± 5.7; P < 0.001). ConclusionThis study presents a large number of patients with a diverse spectrum of neurological manifestations. The rare neurological manifestations reported in our study will contribute to better understanding the neurological involvement of SARS-CoV-2 in children. The study also points out the differences of SARS-CoV-2-related neurological manifestations between patients at different ages. Physicians should be alert about recognizing the early neurological manifestations of the SARS-CoV-2 in children.
