Summary

This study tested whether a single session of playing Tetris after briefly recalling a traumatic childbirth memory could reduce the number of intrusive memories and PTSD symptoms in new mothers. 120 women who had given birth at least six weeks ago and reported frequent intrusive memories were randomly assigned to receive the intervention immediately or after a waiting period. The approach aims to disrupt the memory reconsolidation process using a simple visuospatial task.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
behavioral intervention: brief childbirth memory recall followed by Tetris gameplay
What this could lead to
If it works, this could offer a simple, low-cost way to reduce distressing intrusive memories after childbirth, improving maternal mental health.
What could go wrong
This is a small, early-stage trial (120 participants) with a behavioral intervention, not a drug. The effect may be modest or not last long, and results may not apply to all women.
