Post-traumatic stress disorder (PTSD) is an anxiety disorder that affects people who have experienced traumatic events, such as war or rape, and it can cause symptoms such as flashbacks that could affect their ability to function. Research suggests that certain video games help with PTSD symptoms. In one study, participants who played Tetris, a video game that requires visual-spatial skills to stack shapes, within six hours after exposure to a movie that included disturbing images reported fewer flashbacks than people who did not play the game. Researchers believe that engaging the brain with visual-spatial activities in the short-term aftermath of traumatic events might prevent the brain from fully creating mental images of the event, thus reducing the frequency of flashbacks.
