A psychiatrist at the University of Oxford require some healthy gaming operators, "Tetris", a video game where players are rows of colored boxes, immediately after that contains a movie, the elements of the traumatic events and images is required.

The results showed that after seeing the movie, flashbacks participants who played video games with less experience in the next week that they do not play video games.

Existing treatment is used after a diagnosis of PTSD.

"This is just the first step shows, this could be a preventive approach to PTSD," says study leader Emily Holmes. "This is a scientific experiment, how the mind works, from here we can try to understand the bigger picture. There are too many things to do this experiment possible treatment."

According to investigators, the process of recognition of colors and shapes moving in a game of Tetris to directly experience an event, a competition between the forces of the game image and psychological traumas that are present in the brain.

"We want to reduce hindsight, in the form of a series of images of the trauma, if present in the memory of people with PTSD go," said Holmes. "Tetris is a way to compete with the source of sensory information in the brain to work. Tetris with the operation of sensory memory that the facts presented to the trauma, thereby reducing the number of setbacks."

Tetris also disrupt the process of the reference to the visual experience. The game has the memory of the circumstances of the incident.

"We know it takes 6 hours to affect the memories in the minds of some people," said the researchers from Oxford deep Catherine Rose.

"We have shown that in healthy participants play tetris, flashback type memory without reducing the ability to perceive the incident."

The researchers want to alleviate their findings in a way that the symptoms of PTSD to happen before they develop.
