Tetris After Trauma Can Reduce Risk, Severity of Flashbacks

Tetris is a computer puzzle game that requires players to move tiles around on a screen. The study suggests this use of visual and spatial memory may interrupt the formation of traumatic memories. This may reduce their emotional impact, thereby reducing the risk and severity of intrusive flashbacks after a traumatic event.

Tetris to Reduce Flashbacks

The study followed 71 people admitted to a United Kingdom emergency room after a car accident. Half received the usual care. The other half received an alternative intervention within six hours of the accident. They discussed the traumatic event and then practiced playing Tetris. Researchers gave participants a version of the game to play on their own after leaving the emergency room.

Participants logged their traumatic memories relating to the accident for a week. Those who played Tetris and talked about their trauma after their accident had 62% fewer flashbacks following the accident. The frequency of flashbacks and intrusive memories also declined more quickly in the intervention group than in those who received standard care.

The study’s authors hypothesize that the visuospatial demands of the game may interfere with the brain’s ability to encode the traumatic memory. This interruption can reduce both the frequency and severity of intrusive trauma-related memories.

Tetris as a Preventative Treatment for PTSD?

Though the role of Tetris in preventing PTSD might seem surprising, previous studies support the link. A 2012 study presented at the British Psychology Society Annual Conference reached similar conclusions. For that study, researchers showed participants a frightening movie, then asked some participants to play Tetris. Compared to participants who did not play the game, those who played Tetris reported fewer intrusive memories of the movie in the week after viewing it.

    I will try this, I was badly traumatized by my therapist who sexually exploited me, and caused a great deal of emotional harm.
    He gave me worse PTSD, and now I have two to three panic attacks daily. And the nightmares are scary.
