Noninvasive Brainwave Technology Reduces PTSD Symptoms

Wake Forest Baptist Medical Center in North Carolina Finds Relief for Veteran PTSD Sufferers


Orange County, CA - January 3rd 2018 -  The U.S Department of Veteran Affairs approximates 31 percent of Vietnam Veterans, 10 percent Gulf War veterans, and 11 percent of Afghanistan war veterans experience PTSD. Symptoms can include irritability, insomnia, and re-experiencing traumatic events amongst many others. Thankfully, due to a research study conducted at Wake Forest Baptist Medical Center in North Carolina, patients suffering from PTSD may find relief.

The neurotechnology implemented by the research team is known as High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM).  A noninvasive, closed-loop, acoustic stimulation approach in which computer software algorithms translate specific brain frequencies into audible tones in real time. Charles H. Tegeler, M.D., the study’s principal investigator and professor of neurology at Wake Forest School of Medicine simplified the process by stating, “In essence, this gives the brain a chance to listen to itself through an acoustic mirror.”

Resonance between brain frequencies and the acoustic stimulation allows the brain to self-adjust towards improved balance and reduced hyperarousal with no conscious or cognitive activity required. The objective is to reset the brain’s stress response patterns that have been rewired by repetitive physical and nonphysical traumatic events.

The study involved 18 service members or recent veterans, who experienced symptoms over one to 25 years. Over the course of 12 days they received an average of 19 HIRREM sessions however, the study proved flawed and requires further inspection. The number of participating veterans was not a sufficient sample, and the lack of a control group left no option for comparative analysis. Additionally, it was an open-label project, meaning that both researchers and participants knew what treatment was being administered.

Data from the involved patients was collected from six sessions, before and after, as well as three follow-up interviews given online in the 6 months post treatment. Additional patterns recorded included heart rate and blood pressure observations. Of these findings, Tegeler said, “We observed reductions in post-traumatic symptoms, including insomnia, depressive mood and anxiety that were durable through six months after the use of HIRREM, but additional research is needed to confirm these initial findings. This study is also the first to report improvement in heart rate variability and baroreflex sensitivity – physiological responses to stress – after the use of an intervention for service members or veterans with ongoing symptoms of post-traumatic stress.”
