What's Happening?
A recent study published in the journal Alzheimer's & Dementia: Translational Research & Clinical Interventions has revealed that playing a specific free online speed-training video game could potentially lower the risk of dementia by 25%. The study tracked
nearly 3,000 participants aged 65 and older over a 20-year period. Participants were divided into four groups: one group did nothing, another engaged in memory training, a third group focused on reason training, and the last group played the speed-training video game. The game involved finding objects on a screen quickly and making decisions about them. Those who participated in the speed-training sessions, which included up to 10 sessions over five weeks and additional booster sessions over three years, showed a significant reduction in dementia diagnoses compared to those who did not receive any cognitive training.
Why It's Important?
The findings of this study are significant as they suggest a non-invasive, accessible method to potentially reduce the risk of dementia, a condition that affects millions of people worldwide. The study highlights the importance of cognitive activity in maintaining brain health, particularly as people age. The speed-training game appears to enhance processing speed, which may be protective against certain types of dementia, such as subcortical dementias. This research could influence public health strategies by promoting cognitive training as a preventive measure against dementia, potentially reducing healthcare costs and improving quality of life for older adults.
What's Next?
While the study's results are promising, experts emphasize the need for further research to confirm these findings across a broader population. Neurologists like Clifford Segil, DO, suggest that more extensive studies are necessary to determine the reproducibility of these results. Additionally, while the game shows potential, it is not yet recommended as a definitive preventive measure against dementia. Future research may explore the integration of such cognitive training games into regular health practices for older adults, alongside other activities like reading, learning new skills, and physical exercise, which are also known to support brain health.
