O que é Síndrome de miastenia?

A Miastenia é uma doença neuromuscular caracterizada pela súbita interrupção da comunicação natural entre nervos e músculos, causando fraqueza muscular e dificultando – ou até impedindo – que a pessoa execute movimentos de forma voluntária.

Quais os tipos de miastenia?

Há duas formas de miastenia: a autoimune, ou adquirida, e a congênita. Na autoimune, a resposta imunológica se volta contra os componentes da placa motora responsável pela transmissão do estímulo nervoso que faz o músculo contrair. Na congênita, os anticorpos produzidos pela mãe passam pela placenta e atingem o feto.
