Breaking New Ground in Trauma Treatment: Tetris as a Therapeutic Tool
Recent research reveals that playing Tetris can significantly alleviate symptoms of post-traumatic stress disorder (PTSD) by occupying the brain, thereby blocking intrusive memories associated with trauma. The study, published in The Lancet Psychiatry, introduces a treatment method known as the Imagery Competing Task Intervention (ICTI), developed at Uppsala University in Sweden in collaboration with P1vital and trialed at the University of Cambridge and the University of Oxford.
Understanding Intrusive Memories and PTSD
Intrusive memories, often manifesting as vivid flashbacks, are a common symptom of PTSD, arising from psychological trauma such as unexpected deaths or violent experiences. These memories can intrude unexpectedly, disrupting daily life and affecting mental and physical health. Professor Emily Holmes, a leading psychologist at Uppsala University, underscores the power of even a fleeting intrusive memory, which can hijack an individual’s attention and evoke unwanted emotions.
Study Methodology and Findings
To investigate the effectiveness of ICTI, the research team focused on healthcare workers who had faced traumatic events during the COVID-19 pandemic. Participants were divided into three groups: one utilized the ICTI intervention, the second engaged with classical music, and the third received standard treatment.
The results were compelling. Those receiving ICTI reported a substantial reduction in intrusive memories—from an average of 14 per week to just one within four weeks. Remarkably, six months after the intervention, 70% of participants in the ICTI group experienced no intrusive memories.
Holmes notes that this intervention capitalizes on mental imagery rather than verbal processing, aiming to be practical and gentle to accommodate the busy lives of individuals.
How the ICTI Treatment Works
Central to the ICTI method is the popular video game Tetris. The treatment begins with participants briefly recalling their traumatic memory without delving into specifics. Following this, they learn to employ mental rotation—a cognitive skill that utilizes the imagination. Participants then engage in Tetris, carefully manipulating shapes to fit them into a grid in sessions lasting approximately 20 minutes.
The cognitive engagement required by Tetris occupies the brain’s visuospatial areas, effectively competing with and diminishing the emotional intensity and frequency of traumatic flashbacks.
Comprehensive Benefits Beyond Intrusive Memories
While the primary aim of the ICTI intervention is to reduce intrusive memories, the researchers discovered broader benefits in overall PTSD symptoms. Participants experienced improvements in anxiety, depression, and overall functioning by the fourth week, regardless of their baseline PTSD severity. This suggests that reducing intrusive memories can have a positive ripple effect across multiple dimensions of mental health.
Conclusion
The introduction of Tetris as a therapeutic tool highlights an innovative approach to trauma treatment, offering hope for individuals grappling with the lingering effects of PTSD. As mental health professionals continue to seek effective interventions, the promising results from this study may pave the way for more accessible and engaging treatments for those affected by traumatic experiences.
In a world still grappling with the aftermath of collective trauma, such research underscores the potential for creative solutions in powerful healing. The findings remind us that sometimes, an engaging game might just be the key to recovery.
