Post-COVID acute disseminated meningoencephalitis in a 2-year-old child

Among all published studies, it has been noted that in COVID-19, in addition to respiratory system dysfunction, one-third of patients (30–35%) exhibit signs of nervous system (NS) involvement. Descriptions of various neurological diseases complicating the course of coronavirus infection (COVID-19) or representing its unique clinical manifestation are available. One of the neurological complications of COVID-19 is meningoencephalitis. This article examines the clinical presentation, diagnosis, and treatment of acute disseminated meningoencephalitis (ADME) that developed in a child following COVID-19. Special attention is given to the pathogenesis of the disease, which is associated with the body's immune response to the SARS-CoV-2 virus, leading to inflammatory processes in the central nervous system. Data from instrumental and laboratory diagnostics, as well as treatment are presented. The importance of early detection and comprehensive treatment to prevent severe neurological complications and improve prognosis in young patients is emphasized.
