Researchers from Tel Aviv University have successfully used brain-scanning technology to predict which soldiers are more at risk of stress than others. The researchers studied a group of 50 army medics recording brain activity before they started active duty. They also measured the participants' stress symptoms when they were first drafted and a year-and-a-half later when they started active service. Using this information they were able to develop predictive brain measurements for whether or not a soldier would develop PTSD (post-traumatic stress disorder). Activity in an area of the brain called the amygdala was found to be closely linked to whether or not soldiers developed PTSD.
