The BMC Medicine study, led by Professor Emily Holmes, enrolled over 70 participants recently exposed to trauma.
Researchers used a randomized controlled trial to compare the effects of a single session of a specific game intervention against a control group.
Participants tracked their flashbacks in the following week.
The results were astonishing: those who played the game reported a 93% reduction in flashbacks compared to controls.
This impressive outcome not only highlights the game’s therapeutic potential but also marks a major step forward for trauma interventions.

2. Tetris: The Surprising Intervention

Researchers selected Tetris as the intervention because its visual-spatial gameplay uniquely engages the brain.
When played shortly after recalling a traumatic memory, the game’s demands appear to disrupt how those memories are stored.
This process, known as memory reconsolidation, may be interrupted by the intense focus and pattern recognition Tetris requires.
As a result, the formation of vivid, distressing flashbacks is greatly reduced, offering a simple yet powerful tool for managing trauma’s lingering effects.
