TWENTYNINE PALMS, Calif. (AP) - A military experiment in California is meant to try to predict who's most at risk for post-traumatic stress disorder.
Earlier this year, a quarterly publication from a national PTSD center found that studies to date had looked at only "a narrow band of the potential risk and resilience predictors."
Select Marine and Army units are undergoing a battery of physical and mental tests before deployment including genetic testing, brain imaging and stress exams. They are followed in war zones and upon return.
Similar research is ongoing at the University of Texas at Austin.
Scientists have collected detailed health data from 178 soldiers from Fort Hood who recently came back from Iraq. The post was the scene of a Nov. 5 massacre blamed on an Army psychiatrist. The gunfire killed 13 people and left 29 wounded.
