Traumatized? Playing Tetris may reduce flashbacks

The rapid-fire visual puzzles that make Tetris so engrossing may also make the video game a promising treatment for post-traumatic stress, a new study suggests.

Recurring, intrusive thoughts of a traumatic event (or events) are one of the hallmark symptoms of post-traumatic stress disorder (PTSD), a type of anxiety disorder. According to the study, which appears in the journal PLoS ONE, playing Tetris soon after a traumatic experience appears to protect against these flashbacks, by distracting the brain from the event and short-circuiting how upsetting memories and images are stored.

Not just any video game will do. Notably, the study found that games that rely on trivia or language skills don't appear to have the same therapeutic effect as stacking Tetris blocks, probably because they activate different areas of the brain.

"Verbal tasks may not be as effective because they will not affect the same neural networks," says Dr. Alexander Obolsky, M.D., a professor of psychiatry at Northwestern University, in Evanston, Illinois, who specializes in the treatment of PTSD. "It's a different part of the brain that processes that information." (Obolsky was not involved in the new research.)

To explore the effect of Tetris on post-traumatic stress, researchers in the UK used a well-known lab model of trauma: They showed a series of upsetting film clips (fatal car accidents, graphic surgery) to 60 people, then asked the participants to record how often they experienced flashbacks from the film.

The volunteers, who had no history of mental health problems, were divided into three groups. Shortly after watching the film, one group played Tetris, another played a word-based quiz computer game, and the third simply sat quietly.

In the first 10 minutes, the participants who played Tetris had just four flashbacks, on average. By comparison, the quiz-game players had about six flashbacks, and the participants who did nothing had 12 flashbacks.

More importantly, the protective effect of Tetris seemed to be lasting. Over the following week, members of the Tetris group continued to experience fewer flashbacks compared with the quiz-game and control groups. (The researchers asked the participants to record their flashbacks in a diary.) The group who played the quiz game actually experienced more flashbacks over the week than the group who did nothing.

"A visuospatial task such as Tetris may offer a 'cognitive vaccine' against the development of PTSD flashbacks after exposure to traumatic events," the researchers concluded. The study was led by Emily Holmes, a senior research fellow in psychiatry at Oxford University.

While the results of the experiment suggest a way to head off PTSD, much more research is needed before experts can start recommending Tetris or similar visual tasks for trauma victims in the real world.

"If this indeed keeps working in various situations in further studies, then perhaps at one point we can try it with people who have actual PTSD," Obolsky says. But, he adds, "there are years before this may or may not have something to do with what I do in my office with my patients."

Effective therapies that can be administered within hours of a traumatic event are desperately needed, Holmes and her colleagues write. In fact, they note, some existing forms of early intervention counseling can even make PTSD symptoms worse.

    All part and parcel of repetitive stimuli producing seratonin-led chemicals in the brain. Also happens when the posterior parietal cortex is disrupted during religious ceremonies and orgasm.

    Explains a lot of repetitive ceremony within group behaviour and designed to bring participants comfort, thereby making them stay in the group.

    I have a severe personality disorder and Social Anxiety Disorder-not to be confused with pain old Social Phobia. Both are paralyzing and all consuming. I really don't think about anything else when I'm playing and I find it exciting to "crush" the lines. I think for me it increases the seratonin; it picks me up. I love seeing how far I can get before it's too fast; it's how I relax and disrupt my thought patterns during the day.

    I had extreme back pain during the end of one of my pregnancies. (I have old injuries.) Each evening, I sat in the recliner and played my kids' handheld tetris. It distracted from my discomfort, something I could not get from just relaxing, reading or watching television. Tetris doesn't help the carpel tunnel though...

    I'll attest to the miraculous properties of Tetris – I am classic white-knuckle flyer - if I could fly under general anesthesia, I would I've tried Alcohol, even dangerous combos of pills and alcohol to no avail – effects are brief. The body, when mind is (irrationally) convinced a 35.000 foot plummet and fiery group death is imminent, resists sedation mightily. Only Tetris has worked. Something about the escalating suspense as speed is ratcheted up. Powerful medicine, no hangover. And a clear mind should worst imaginings materialize. Hail Tetris!

      PTSD and Phobia's are both of the mind, and as real to the person experiencing them as the real thing.
      A person who has a severve phobia, does not need to experience the real thing, as it is the simple
      thought of it that causes the distress.

      You statement could easily equate to those who tell PTSD suffers to get over It you lived through it, so stop whining.

    I don't think the writeup suggests that playing the game ought to comprise the entirety of therapy, only that it may help as part of overall treatment plan. One doesn't have to be a neuroscientist or psychiatrist to understand why – It's fairly commonsensical that when a feedback loop (flashback0 is interrupted - by whatever means - the lull (besides being a relief in itself) may act to somehow dilute strength of impulse in future.

      I think it does suggest it. Added by the fact the study used an extremely mild irritant such as watching videos, further dilutes the study. People who suffer from PTSD are extremely unique, the uniqueness including specifically what sets off bad days and very bad episodes. A certain smell...a picture of something, etc. etc..

      I think its a poor study and quite frankly offensive to people who suffer from severe PTSD that they can pick up Tetris and feel better.

    How can you equate seeing some photos or a video of a "graphic" scene with actually having your life or someone else's threatened? The ethics alone will prohibit such a study. So saying this will help those with PTSD is assuming a lot and giving false hope to those trapped in a living hell who have PTSD. The study has far too many holes in it (a diary of self reporting?) (no actual life threats to self or others) (etc..) to even be publishable...much less reported on a global news network.

    I actually suffer from PTSD and I think that the rapid eye movement that takes place while playing a game of Tetris is the reason why it alleviates some of the anxiety symptoms. EMDR is used to treat patients with PTSD and the rapid eye movements that are associated with this treatment are what brings both sides of the brain together. Tetris may serve as a "distraction" which in my opinion is what this article is trying to suggest, but I don't think the distraction is what truly helps PTSD sufferers.

    I don't think that it's the "distracting game" that helps. It's the movement of the eyes back and forth that engages both sides of the brain and helps to properly "file" the memory in the brain. It's basically a form of EMDR. I have PTSD from childhood sexual abuse and have had mixed results from EMDR, but I have fellow survivors that it has worked wonders for.

    I have ADHD (non medicated) and played tetris for hours when i had to write and organize term papers for college. I found that after an hour or 2 of serious tetris playing, that my ability to organize information and words became stronger. I was 37 when i went to college, was told at community college when I started that I wouldn't make it. I learned tetris from my daughter, left CC with a 3.7 GPA and graduated from a stringent 4 yr writing college with a gpa of 3.57. Does tetris work, ABSOLUTELY!

She attended a downtown NYC elementary school at the time whose upper floors were in view of the Towers. I guess she was instinctively self medicating. This article was very interesting. Thank you!

    Before computer games were everywhere, I went through an assault. Took me a long time to get beyond it and learn how to use it - you went throught THAT, you can do anything. I forced it to become a strength. Too muleheaded to give ujp, I guess.

    Long before I reached that stage, I would have loved having even a silly computer game as a distraction. If It had even slightly helped me not have those nightmares and thoughts every minute, I would have welcomed it.

    how MANY millions (probably billions) of dollars have been wasted in NOT finding answers for PTSD sufferers that truly work by Duke? Look what they did to the Vietnam Vets, the blacks, the entire state of NC.
    And why is EMDR patented for HOW MANY YEARS!!! Tetris doesn't stop flashbacks and it doesn't lessen the occurance of them.
