Palabras clave:

TDAH, ressonância magnética estrutural, ressonância magnética funcional, rede cerebral padrão, conectividade funcional intrínseca, conectividade funcional em estado de repouso

Resumen

Essa revisão descreve primeiramente o funcionamento das metodologias de ressonância magnética: morfometria baseada em voxels, morfometria baseada em superfície, imagem por tensor de difusão, ressonância magnética funcional com aplicação de tarefas neuropsicológicas e sem tarefas, historicamente conhecida como ressonância funcional em estado de repouso. Em seguida, traz os principais achados da aplicação dessas técnicas no estudo do TDAH.
