Why is cognitive training important for seniors?
After the age of 50, the brain's processing speed naturally declines by approximately 20% per decade. This decline is not entirely inevitable — longitudinal studies by the National Institute on Aging have shown that regular cognitive exercise, combined with physical activity and social interaction, can maintain and even improve cognitive function well past 80.
The best-known study on this topic, ACTIVE — Advanced Cognitive Training for Independent and Vital Elderly — followed 2,832 seniors for two decades. The result published by the Journal of the American Geriatrics Society shows that processing speed training (similar to our "Useful Field of View" game) reduced the incidence of diagnosed dementia by 29%. Moreover, each booster session added further benefit.
The Lancet Commission 2024 on dementia prevention identified 14 modifiable risk factors. Cognitive training is part of the recommended strategy, alongside regular physical exercise, weight management, blood pressure control, avoiding social isolation and protecting hearing.
