The program uses video-game type graphics to depict war-zone attacks and explosions in Iraq.
"Virtual reality simulation is used as something called exposure therapy," says Lewine. "So, the idea is that as individuals come through the program, they get virtual reality, they get behavioral assessments, they get psychiatric assessments and all that information is then pooled to guide individuals to the treatment that we think is most effective."
The V.A. program was developed by the University of Southern California's Institute for Creative Technologies and is also being researched by the U.S. military at the Naval Medical Center in San Diego, California.
