What new non-drug approaches to treating PTSD are on the horizon?
My husband purchased a virtual reality headset a couple of years ago to enhance his workout routine. I thought whatever supports his efforts to maintain his health and increase his chances of a longer life, go for it! Two years later, he continues to use it, so I’m grateful it was not just another impulse purchase that sits on a shelf somewhere. His continued use of it reflects virtual reality’s potential staying power. What does any of this have to do with PTSD treatment?
One of the first-line evidence-based treatments for PTSD is prolonged exposure therapy. Prolonged exposure is a trauma-focused psychotherapy that supports people as they confront memories, feelings, and situations that they avoid since their trauma. The premise of this approach is to gradually teach them that their trauma-related memories and cues are no long dangerous in the present and don’t need to be avoided. One approach to prolonged exposure is imaginal exposure where the person revisits the traumatic memory in their imagination and recounts the event. This imaginal exposure causes the person a great deal of distress, promoting emotional engagement with the trauma memory. It is then followed by cognitive processing of the experience of revisiting their trauma. Although effective, might there be another approach that might reduce the level of distress by speeding up the psychophysiological habituation process through this approach?
That is the exact question that the VA attempted to answer in a recent research study. They wondered if they added repeated, bifrontal direct neurofeedback (AKA transcranial direct stimulation) to therapeutic exposure using virtual reality, would it reduce the symptoms of PTSD perhaps faster. The VA already recognized the significant potential of noninvasive brain stimulation as a novel treatment to reduce PTSD symptoms, specifically in the particularly difficult population of military veterans. They had conducted a prior pilot study that showed promising findings which prompted them to move forward with the gold standard of research, a double-blind randomized clinical trial. This RCT replicated the key findings of the pilot study, including significant improvements in self-reported PTSD symptoms, reductions in autonomic arousal, and improvements in their social functioning. They concluded that combining repeated direct neurofeedback with virtual reality is a promising strategy and highlights the innovative potential for these combined technologies.
