Neuroimagem, transtorno bipolar, circuitos neuronaisResumo
Nas últimas décadas, pesquisas de neuroimagem no transtorno bipolar (TB) têm demonstrado anormalidades nos circuitos neuronais supostamente envolvidos no processamento e na regulação da emoção, bem como no processamento de recompensas. Entretanto, os resultados relativos a diversas estruturas do sistema nervoso central são escassos e difíceis de serem comparados, devido à grande heterogeneidade do TB e às diferentes metodologias empregadas para a coleta das imagens. Esta revisão teve como objetivo sintetizar os principais achados em neuroimagem estrutural e funcional no TB, descrevendo as estruturas corticais e subcorticais do encéfalo mais relevantes e que embasam a provável fisiopatologia desse transtorno.
