Abstract

Resumen

Esta revisión pretende comprobar si el entrenamiento de Neurofeedback (NFB) es eficaz para la mejora sintomática del Trastorno de Estrés Postraumático (TEPT) en población adulta.  Se realiza una búsqueda de estudios en las bases de datos PubMed y Science Direct.  Los cinco estudios encontrados se centran en la regulación de la amplitud alfa con el entrenamiento de Neurofeedback a través del electroencefalograma (EEG) e imagen por resonancia magnética funcional (fMRI).  En ellos se obtiene un aumento de amplitud alfa (“reboteâ€) tras el entrenamiento, asociado con la mejora sintomática, una mayor relajación y una conexión significativa entre amígdala y prefrontal.  En base a la literatura, los resultados no reportan la eficacia y evidencia suficiente, pero se considera que la neuromodulación obtenida con NFB y asociada a la mejora sintomática, puede potenciar un progreso para el tratamiento tanto del TEPT como de otras patologías.

Palabras clave: Trastorno de Estrés Postraumático (TEPT); Neurofeedback (NFB); alfa; amígdala; córtex prefrontal; regulación emocional; revisión sistemática.

 

Abstract

The given review tryes to verify if the trainning on Neurofeedback (NFB) provides a symptomatic improvement on the Posttraumatic Stress Disorder (PTSD) in an adult population.  A search of studies is made in PubMed and Science Direct databases.  The five studies found focus on the regulation of alpha amplitude with the training of Neurofeedback through electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI).  An increase in alpha amplitude ("rebound") is obtained after training, associated with symptomatic improvement, greater relaxation, and a significant connection between amygdala and prefrontal cortex.  According to the literature, there´s not enough efficiency or evidence on the results, but it´s considered that the neuromodulation obtained through NFB and its associated symptomatic improvement, can enhance a progress for PTSD and other pathologies treatments.

Keywords: Posttraumatic Stress Disorder (PTSD); Neurofeedback (NFB); alpha; amygdale; prefrontal cortex; emotional regulation; systematic review.

 

Resumo

Esta revisão visa verificar se o treinamento de Neurofeedback (NFB) é efetivo para a melhora sintomática do transtorno de estresse pós-traumático (TEPT) na população adulta.  Uma pesquisa de estudos é realizada nos bancos de dados PubMed e Science Direct.  Os cinco estudos encontraram foco na regulação da amplitude alfa com o treinamento Neurofeedback através do eletroencefalograma (EEG) e ressonância magnética funcional (fMRI).  Neles, um aumento da amplitude alfa ("bounce") é obtido após o treinamento, associado à melhora sintomática, maior relaxamento e uma conexão significativa entre amígdala e pré-frontal.  Com base na literatura, os resultados não relatam a eficácia e evidências suficientes, mas considera-se que a neuromodulação obtida com a NFB e associado à melhora sintomática pode potencializar o progresso no tratamento de TEPT e outras patologias.

Palavras-chave: Transtorno de estresse pós-traumático (TEPT); Neurofeedback (NFB); alfa; amígdala; córtex pré-frontal; regulação emocional; revisão sistemática.
