Two previous CADTH Rapid Response reviews reported on neurofeedback and biofeedback for mood and anxiety disorders. The review published in 2012 reported that evidence from mostly preliminary analyses suggested that neurofeedback and biofeedback may have potential for the treatment of post-traumatic stress disorder (PTSD), generalized anxiety disorder (GAD), or depression. The review published in 2014, assessed evidence identified since the publication of the review of 2012 and reported that limited evidence suggested that biofeedback may decrease the symptoms of PTSD or depression. Both the reviews reported that no relevant evidence based guidelines on neurofeedback or biofeedback were identified. The purpose of this review is to evaluate the more recent evidence regarding the clinical effectiveness of neurofeedback or biofeedback compared with other modalities for the treatment of mood and anxiety disorders (PTSD, GAD, or depression) in adults. Additionally, this review aims to review recent evidence-based guidelines regarding the use of neurofeedback or biofeedback for the treatment of mood and anxiety disorders (PTSD, GAD, or depression) in adults.
