For those that suffer from it, Post-Traumatic Stress Disorder can be one of the singularly most debilitating things imaginable. Brought about by surviving traumatic events (hence the title), some of the earliest research into the phenomenon is what gave us the diagnosis of "shell-shock" within soldiers, dating all the way back to as early as the First World War.
As we've studied the disorder more and more over the last few years, we've learned that it can affect a number of victims, from people who've suffered sexual assault, traffic collisions, and other threats on their lives. The results are often mentally crippling, and can cause people who suffer from PTSD to constantly experience a sudden onrush of a "fight-or-flight" feeling when no danger is actually present.
It's estimated that nearly 9% of U.S. citizens develop PTSD at some point, and that number's only expected to climb. However, researchers think they might have actually found a treatment for it, and strangely enough, the solution is to listen to your brain. Literally.
