A non-invasive brainwave mirroring technology has been developed in United States to reduce the symptoms of post-traumatic stress in military personnel.
According to a study published in the journal of America’s Military Medical Research, a team of scientists used a high-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM) — a non-invasive method, in which computer software algorithms translate specific brain frequencies into audible tones in real time.
Post-Traumatic Stress Disorder (PTSD) signifies the failure to recover after experiencing or witnessing a terrifying event.
After six months of using the technology, it resulted in depletion of post-traumatic symptoms, including insomnia, depressive mood and anxiety. The technology works through resonance between brain frequencies and the acoustic stimulation, where the brain is supported to make self-adjustments towards improved balance and reduced hyperarousal.
It requires no conscious or cognitive activity. The net effect is to support the brain to reset stress response patterns that have been rewired by repetitive traumatic events, physical or non-physical, the researchers said.
On this, lead investigator Charles H. Tegeler, Professor, Wake Forest Baptist Medical Centre in North Carolina stated, “Ongoing symptoms of post-traumatic stress, whether clinically diagnosed or not, are a pervasive problem in the military.”
“Medications are often used to help control specific symptoms, but can produce side effects. Other treatments may not be well tolerated, and few show a benefit for the associated sleep disturbance. Additional non-invasive, non-drug therapies are needed,” Tegeler added.
This provides a chance for the brain to listen to itself through an acoustic mirror, he said.
