Neurofeedback no transtorno de estresse pós traumático!
Wednesday, 19 de January de 2022
O Neurofeedback ou Biofeedback de EEG surgiu na década de 60 como um método que usa o condicionamento operante para reciclar padrões de ondas cerebrais. Desde então, muitas pesquisas se aprimoraram sobre sua eficácia e aplicabilidade em diversas patologias, como por exemplo no tratamento de epilepsia, Transtorno Obsessivo-Compulsivo (TOC), ansiedade, alcoolismo, Transtorno do déficit de atenção hiperatividade (TDAH), transtorno de estresse pós-traumático, entre outros.
O Transtorno do estresse pós traumático (TEPT) têm início após um evento extremamente traumático e consiste em uma série de reações disfuncionais intensas e desagradáveis sempre que o trauma é lembrado, ou seja, a pessoa revive o episódio como se estivesse ocorrendo naquele momento, desencadeando as mesmas sensações de dor e sofrimento que o agente estressor provocou no passado. Essa recordação desencadeia alterações neurofisiológicas e cognitivas. Sendo assim, esse transtorno pode impactar negativamente os processos biofisiológicos, particularmente aqueles relacionados ao cérebro.

Essa recordação desencadeia alterações neurofisiológicas e cognitivas. Sendo assim, esse transtorno pode impactar negativamente os processos biofisiológicos, particularmente aqueles relacionados ao cérebro.
Uma forma inovadora e eficaz que veem demonstrando resultados significativos no TEPT é o Neurofeedback. Este tratamento utiliza neuromodulação autorregulatória com o objetivo de melhorar o funcionamento cerebral. Ele modula a atividade do cérebro por meio do monitoramento e feedback em tempo real dos sinais de EEG ou fMRI, ou seja, utiliza sensores que captam sinais elétricos dos neurônios, sendo decodificados e processados por um software especifico que é acompanhado pelo paciente em tempo real por meio de um computador. A partir de então, a pessoa vai aprendendo e sendo treinada a melhorar a atividade cerebral.
Diversos estudos encontraram resultados bem-sucedidos de neurofeedback no tratamento de TEPT, principalmente em pacientes que não responderam a outros tratamento. Pois, a atividade cerebral relacionada ao TEPT induzida repetidamente durante a sessão de feedback pode alterar sua frequência de aparência espontânea após a sessão, além disso, é indolor, não invasivo e sem muitas contraindicações. Falando nisso, na nossa plataforma dispomos de vários tipos de EEG que podem captar a atividade cerebral!!!
