Autoimmune encephalitis (AE) is defined as neurological syndromes of subacute installation of compromise of consciousness, alteration of working memory and psychiatric disorders associated with abnormal movements and epileptic seizures and that are produced by the action of anti-neuronal antibodies. They bind to neurotransmitter receptors or membrane proteins. Antibody to NMDAR is the origin of the majority of cases of AD in children and young adults, followed by anti-LGI1 antibody for presentation in adults. The AE has increased in the last decade, with a large number of new agents described that produce mostly neurological syndromes that involve the central nervous system, with predominance of psychiatric signaling, except in children and the predominant abnormal movements, epileptic seizures and compromise of conscience. They are frequently associated with tumors in adults but in children this association is more infrecuent. All AEs respond to immunomodulatory therapy although in different measures depending on the type of antibody involved. In general, the evolution to improvement is slow and can be completed in months or even in one year or more. In this review, the main EA clinical pictures related to specific antibodies are highlighted, also mentioning recently discovered immunophenotypes.
