New research involving Oxford researchers has shown that a simple digital intervention that includes gameplay can dramatically reduce intrusive memories of trauma in a month, even to the point of being symptom-free after six months. This treatment was also very effective at reducing the symptoms of post-traumatic stress disorder (PTSD) more generally. The findings have been published this week in The Lancet Psychiatry.
