Exposure to trauma can affect brain function in healthy people several years after event
Exposure to trauma may create enough changes in the brain to sensitize people to overreact to an innocuous facial gesture years later, even in people who donít have a stress-related disorder, says new research. It appears that proximity to high-intensity traumas can have long lasting effects on the brain and behavior of healthy people without causing a current clinical disorder.
