Resumo

A amígdala cerebral é crucial para o processamento emocional, comportamental e de sinais sensitivos e motores viscerais. Para exercer essas funções, a amígdala se conecta reciprocamente com regiões corticais e subcorticais. Alguns estudos mostraram que a acupuntura modula a atividade da amígdala e seus circuitos. No entanto, não há revisão de literatura sintetizando e evidenciando o atual estado de pesquisa sobre o assunto. Assim, o objetivo deste artigo é apresentar e discutir as mais recentes evidências sobre o efeito da acupuntura na conectividade funcional em estado de repouso (rsFC)  da amígdala no contexto da pesquisa clínica. A revisão narrativa da pesquisa clínica foi focada em ensaios clínicos (controlados e randomizados) projetados para analisar o efeito da acupuntura na modulação da rsFC da amígdala em condições clínicas. A busca foi realizada nas bases de dados Pubmed, ScienceDirect e Scielo até março de 2022. Os estudos encontrados foram sobre pacientes com transtorno depressivo maior, dispepsia funcional e síndrome pré-menstrual, os quais demonstraram que a acupuntura diminui significativamente os sintomas. Além disso, este efeito terapêutico foi correlacionado com a modulação da rsFC da amígdala com uma gama de regiões cerebrais. De acordo com os dados revisados, pode-se concluir que os mecanismos de ação cerebral da acupuntura estão relacionados, ao menos em parte para as condições clínicas analisadas, ao seu efeito modulador sobre a rede cerebral da amígdala. No entanto, os estudos sobre esse tema são raros, e mais estudos devem ser feitos para esclarecer o envolvimento da amígdala no efeito da acupuntura.
