Tetris may improve conditions for people with post-traumatic stress disorder. In a study of 40 healthy volunteers who were exposed to stressful images and ads for drunk driving, those who played tetris for 10.5 minutes immediately after seeing the images had fewer flashbacks than those who saw the images but didn't play the game.
Oxford scientist Dr. Emily Holmes believes the game may disrupt the memories that are retained of the sights and sounds witnessed at the time, and which are later re-experienced through involuntary, distressing flashbacks of that moment.
More material is added to the growing body of evidence pointing to health benefits of game intervention to impact a wide variety of cognitive conditions.
