Fisiopatología

La fisiopatología de la encefalomielitis diseminada aguda no está clara; sin embargo, se proponen 2 teorías principales:

  • Teoría del mimetismo molecular: desencadenante ambiental → respuesta mediada por células o anticuerpos → reacción cruzada con autoantígenos de mielina (proteína básica de mielina, proteína de oligodendrocitos de mielina, proteína de proteolípidos) → autoanticuerpos contra la mielina → desmielinización
