Wow:
After just one month, researchers found a stark reduction in intrusive memories, commonly known as flashbacks, for those using the Tetris-based treatment – ten times fewer than either control group. It remained highly effective after six months, with 70% of participants who received it reporting no intrusive memories at all, even alleviating other PTSD symptoms.
That's a crazy positive result. Hopefully there is more research into this treatment. My wife still has PTSD and other early childhood trauma related issues that are being treated with NMDR, which is definitely effective, but it sounds like this could potentially accentuate that treatment for a more positive outcome.
