Israeli researchers claim to have developed a pill to prevent Post Traumatic Stress Disorder.

It won’t help with existing cases.  It works by using the hormone cortisol, which scientists believe prevents the “fixing” of traumatic memories in your mind.

Essentially the pill erases traumatic memories, by preventing them from being stored in your mind.  The pill must be taken within 24 hours of a traumatic event.

Studies were done using injections, and were successful.  Israeli researchers think its main use will be on soldiers.
