Espectro clínico de la Encefalitis Autoinmune no NMDAR en pediatría

Abstract

This work presents a narrative review of the main findings in the medical literature on the clinical manifestations of pediatric autoimmune encephalitis (PAE) not mediated by anti-N-methyl-Daspartate acid receptor (NMDAR) antibodies. Prominent PAEs are associated with specific antibodies, such as the voltage-gated potassium channel complex, glutamic acid decarboxylase, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor, and alpha-amino -3-hydroxy-5. -methyl-4isoxazolepropionic acid receptor. -gamma-aminobutyric. Diagnosis of this pathology is a challenge in pediatrics due to the complexity of psychiatric and neurological manifestations generated by involvement of cortex, limbic system, brainstem, basal ganglia and cerebellum. In turn, understanding its symptoms allows identifying the overlap in clinical presentations between the different types of PAE and the differential diagnosis with other inflammatory diseases of the brain, infections, metabolic diseases and psychiatric disorders. Biomedical knowledge and clinical suspicion of non-NMDAR PAE establishes a growing field of research in neuropsychiatry and favors the diagnosis and treatment of underdiagnosed encephalitides.
