Tetris as Therapy Shows Promise in Reducing Trauma Memories

A UK-Sweden trial with around 40 NHS staff exposed to trauma found that playing a slow version of Tetris while briefly recalling a traumatic memory—an imagery competing task intervention (ICTI)—weakens the vividness of intrusive memories by occupying visuospatial brain areas. Within four weeks, those receiving ICTI had about 10 times fewer flashbacks; at six months, 70% reported no intrusive memories, and PTSD symptoms improved. Led by Emily Holmes, the study is described as a real breakthrough and could be tested in larger groups.
