Special Forces soldiers have neurological differences that make them more resilient to post-traumatic stress disorder than the average soldier, say researchers.
A study of soldiers based at Fort Bragg, North Carolina, found that Green Berets were much less likely to suffer symptoms of PTSD after a week of gruelling exercises that simulated being captured and interrogated by the enemy.
The elite soldiers produced more of a molecule called neuropeptide Y in their blood than regular soldiers. This molecule is generated by the body to help calm the brain in times of extreme stress, says Matt Friedmann, director of the US National Center for PTSD in Connecticut, which carried out the research.
"The Special Forces types had a greater capacity for mobilising neuropeptide Y than ordinary soldiers, and they were also able to sustain it for longer periods," he told a session on PTSD at the American Association for the Advancement of Science's annual conference in Denver, Colorado. Furthermore, neuropeptide Y in Special Forces personnel returned to normal levels within 24 hours, whereas it dipped below normal in the others.
