Trained as a research psychologist, Bourke joined an upstate New York team to provide much-needed and under-supplied mental-health support in the aftermath of 9/11. That experience gave him the opportunity to apply a drug-free protocol he had been using in a clinical setting – a predecessor of his Reconsolidation of Traumatic Memories (RTM) to help veterans with post-traumatic stress disorder. What emerged from the experience 18 years ago, he told The American Legion Traumatic Brain Injury/PTSD Committee Aug. 23 in Indianapolis, was “a real breakthrough for the treatment of PTSD. This is a little unbelievable because it works so well. The fact that it works over 90 percent of the time is really unbelievable.”
