The coronavirus disease 2019 (COVID-19) pandemic has affected mortality and morbidity across all ages, including children. It is now known that neurological manifestations of COVID-19, ranging from headaches to stroke, may involve the central and/or peripheral nervous system at any age. Neurologic involvement is also noted in the multisystem inflammatory syndrome in children, a pediatric condition that occurs weeks after infection with the causative virus of COVID-19, severe acute respiratory syndrome coronavirus 2. ⋯ Emerging data suggest a cohort of patients with COVID-19 will have longitudinal illness affecting their cognitive, physical, and emotional health, but little is known about the long-term impact on affected children and their families. Pediatric collaboratives have begun to provide important initial information on neuroimaging manifestations and the incidence of ischemic stroke in children with COVID 19. The Global Consortium Study of Neurologic Dysfunction in COVID-19-Pediatrics, a multinational collaborative, is working to improve understanding of the epidemiology, mechanisms of neurological manifestations, and the long-term implications of COVID-19 in children and their families.

Coma trajectories are characterized by quick awakening or protracted awakening. Outcome is bookended by restored functionality or permanent cognitively and physically debilitated states. Given the stakes, prognostication cannot be easily questioned as a judgment call, and a scientific underpinning is elemental. ⋯ Most patients who awaken quickly do well and can resume their pretrauma injury lives. In worse off, slow-to-awaken patients, outcomes are a mixed bag of limited innate resilience, depleted cognitive and physical reserves, and adjusted quality of life. Bias and noise are factors not easily measured in outcome prediction, but their influence on recovery trajectories raises some troubling issues.

To enhance knowledge about religious objections to brain death/death by neurologic criteria (BD/DNC), we surveyed hospital chaplains about their experience with and beliefs about BD/DNC. ⋯ Hospital chaplains, who work at the intersection between religion and medicine, commonly encounter religious objections to BD/DNC. To prepare them for these situations, they should receive additional education about BD/DNC and management of religious objections to BD/DNC.

Blend sign on initial computed tomography (CT) is associated with poor outcome in patients with intracerebral hemorrhage (ICH). However, the mechanisms underlying the blend sign formation are poorly understood. The present study aimed to explore the possible mechanism of the CT blend sign in patients with ICH. ⋯ The CT blend sign observed in humans might be composed of two parts of blood with different ages. The hypodense area might be blood with older age and the hyperdense area might be new bleeding.

Acute brain injury (ABI) is a frequent complication of pediatric extracorporeal membrane oxygenation (ECMO) that could be detected by continuous neuromonitoring. Cerebral near-infrared spectroscopy (NIRS) allows monitoring of cerebral oxygenation. ⋯ Cerebral desaturation attested by NIRS was associated with a poor short-term outcome in children of all ages undergoing ECMO, and rScO2 > 80% seemed to be protective. NIRS monitoring might be included within multimodal neuromonitoring to assess the risk of the brain injury related to pediatric ECMO.
