Modificação de memórias desadaptativas durante o sono e a vigília: uma visão interdisciplinar

reativação, memória emocional, sono, transtornos de ansiedadeResumo
As memórias consolidadas podem passar por um período de labilidade diante da apresentação de lembretes (chaves vinculadas ao aprendizado inicial), seguidos por um processo de reestabilização conhecido como reconsolidação. Por outro lado, o sono tem um papel ativo na formação e modificação de memórias, bem como na redução do tom emocional das experiências. Durante isso, as novas memórias são reativadas, reforçadas e integradas às redes de memória pré-existentes. No contexto terapêutico, velhas lembranças podem ser evocadas de acordo com a necessidade do sujeito, o que pode estar desencadeando constantes desestabilizações reestabilizações, talvez sem ter consciência disso. Nesta revisão bibliográfica, discutimos os avanços neurocientíficos relacionados à reativação e modificação de memórias durante a vigília e o sono, bem como os últimos desenvolvimentos em terapias psicoterapêuticas para transtornos de ansiedade, com o objetivo de pensar em uma prática mais interdisciplinar.
