Tetris Gameplay Shown to Significantly Reduce Trauma Memories and PTSD Symptoms
A new study reveals that playing Tetris may dramatically reduce intrusive memories associated with trauma and alleviate symptoms of post-traumatic stress disorder (PTSD). The research, published this week in The Lancet Psychiatry, suggests a simple, accessible digital intervention could transform how PTSD is prevented and treated worldwide.
The study, funded by Wellcome, involved a randomized controlled trial of 99 healthcare workers who experienced trauma whereas working during the Covid-19 pandemic. Researchers found that the Tetris-based intervention significantly reduced intrusive memories within a month, with many participants remaining symptom-free after six months. This finding is particularly significant given the global prevalence of trauma, which affects seven out of 10 people at least once in their lifetime, according to the World Health Organization.
Severe trauma can lead to PTSD, a condition characterized by sudden, unwanted intrusive memories and distressing emotions. Existing therapies for PTSD are often resource-intensive, requiring multiple sessions with specialists and remaining largely inaccessible to many. This research highlights the potential for a scalable, low-intensity, and easily accessible digital treatment option.
The intervention, known as Imagery Competing Task Intervention (ICTI), was developed at the University of Uppsala in Sweden, in collaboration with P1vital, the University of Cambridge, and the University of Oxford. It works by activating the brain’s visual and spatial areas, effectively disrupting the consolidation of traumatic memories. “Even a single intrusive memory, fleeting as it may be, of a past trauma can have a powerful impact on daily life, capturing attention and exposing the person to unwanted and overwhelming emotions,” explained Emily Holmes, professor of psychology at the University of Uppsala, and the study’s coordinator.
Researchers note that psychological trauma – exposure to severe injury, death, or sexual violence – can cause persistent, vivid, and unwanted memories, often experienced as flashbacks. The study, also reported by Digi24 and the Financial Times, offers a promising new avenue for addressing the widespread impact of trauma on mental and physical health. The findings could lead to more widespread adoption of digital therapies for PTSD and related conditions.
A similar study, highlighted by Google News, suggests that the 20-minute sessions rotating Tetris blocks led to symptom disappearance in over two-thirds of users.
