Virtual Reality Treatment for PTSD

In the video about the treatment for PTSD, or Post Traumatic Stress Disorder, they discussed and showed how they are using virtual reality simulations to help soldiers with PTSD to get better. They said that PTSD is from the person reliving the traumatic situations, but having the memory cut off right at the climax, so they do not know if they are going to survive through the event. But with the virtual reality simulation they are forced to relive the whole memory, and it can't get cut off, so they know that they are going to come out of the event completely fine. I think that this is a great way to help people suffering from PTSD, and from the clip it seems like it is highly likely to work on a majority of people suffering from PTSD.
