Estimates say that 8 percent of the population will experience post-traumatic stress disorder sometime in their lives. The disorder arises after someone has a traumatic experience, like assault, an accident, or the horrors of war. The smallest trigger can often make them feel like they're reliving the trauma all over again.
Certain kinds of therapy can help ease a person's emotional reaction to the memory, but what if sufferers could delete the traumatic memories entirely? That's a potential promise of a new development from a team at University of California Riverside, who claim to have successfully erased memories of fear in mice.
