THE WAR WITHIN A ‘LIFETIME SENTENCE’ PHOTO OR ILLUSTRATION CREDIT TK Mark Nystedt HUFFINGTON 07.01-08.12 brain, according to Rigg, the TBI director at Fort Gordon. Many of the symptoms of post-traumatic stress — nervousness, insomnia, anxiety in crowds, jumping at a sudden loud noise — are primitive, involuntary instincts necessary to survival in a combat zone. “I don’t use the term ‘posttraumatic stress disorder’ because I don’t consider it a disorder,” Rigg says. “I mean, you’re in a situation where people are trying to kill you!” When the instinctive, unthinking part of the brain, the amygdala, senses danger, it reacts instantly with a flood of stress hormones that raise blood pressure and heart rate, dilate the eyes to sharpen sight, and squirt adrenalin into the bloodstream — the hyper-arousal that prepares the body for “fight or flight.” That’s appropriate in combat. But back home, the brain may misinterpret danger signals: all strangers are not the enemy; trash along the Interstate probably doesn’t contain an IED; an explosion may be harmless fireworks, a bad dream may be just that.
