Many of us will experience some kind of trauma during our lifetime. Sometimes, we escape with no long-term effects. But for millions of people, those experiences linger, causing symptoms like flashbacks, nightmares, and negative thoughts that interfere with everyday life.
This phenomenon, called post-traumatic stress disorder, or PTSD, isn’t a personal failing; rather, it’s a treatable malfunction of certain biological mechanisms that allow us to cope with dangerous experiences.
PTSD has been called “the hidden wound” because it comes without outward physical signs. But even if it’s an invisible disorder, it doesn’t have to be a silent one.
