N2 - As of June 2022, children represent 18.9% of total cumulated cases of COVID-19 in the United States. While most children have mild symptoms, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect the central and peripheral nervous system function. The most common neurological symptoms in children with COVID-19 are headache, fatigue, anosmia, dysgeusia, and myalgia. In hospitalized children, the most common symptoms are headache, encephalopathy, and seizures. Neurological symptoms are associated with a more severe disease course, and up to a third of hospitalized children with COVID-19 require intensive care intervention. A rare and feared complication is multisystem inflammatory syndrome (MIS-C), a serious condition that involves severe inflammation of different organs, including the brain. Treatment for MIS-C has not been validated and primarily consists of supportive care and immune modulation. Some children with a history of COVID-19 develop persistent symptoms, also known as long COVID. However, recent evidence suggests that long COVID symptoms appear as frequently as in children without a history of COVID-19. Similarly, birth during the pandemic, but not in utero exposure to maternal SARS-CoV-2, is associated with differences in neurodevelopmental milestones. Almost 3 years into the pandemic, the evidence in children is limited. Large-scale studies with adequate pre- and post-pandemic control groups are needed to establish the associations between COVID-19 and short and long-term neurological complications.
