A recent study undertaken by Oxford University has found that playing classic video games like “Tetris” can help to reduce post-traumatic stress disorder (PTSD) flashbacks.
The study, published in the journal PLoS ONE, claims that playing Tetris for a few hours after a traumatic event can prevent flashbacks.
The study tested 60 volunteers, who were made to watch a movie containing scenes of injury and death.
In the first experiment, volunteers were made to watch the movie for 30 minutes and then given a break for 10 minutes. Of the volunteers, 20 played Tetris, 20 played Pub Quiz Machine 2008 and the final 20 did nothing.
Those who played Tetris suffered from fewer flashbacks than others. While those who played Pub Quiz suffered from the worst flashbacks, Fox News reports.
The second experiment extended the time spent watching the movie from 30 minutes to 4 hours.
After watching the film, Tetris players were still found to experience fewer flashbacks than any other group.
According to the research, playing Tetris interferes with visual memories and reduces flashbacks significantly.
David Kwock, general manager for Blue Planet Software, the company which owns Tetris, said that they will be excited if someone uses this theory for clinical application.
