Researchers found that playing an interactive computerized game can delay dementia by about 25% in people over 65. The game tested the ability to recognize images in fast sequences, requiring divided attention and implicit learning. This type of training was more effective than memory or problem-solving tasks.
The study, which involved over 2,800 volunteers, showed that a dual-attention speed brain game contributed to a 25% reduction in dementia diagnoses compared to those who received no training. However, the benefit only lasted for those who had the original and booster sessions. The exact mechanism behind this effect is still unknown.
Experts believe that the game’s ability to activate neurons across the brain, increasing connectivity and plasticity, may be responsible. Additionally, speed training may preserve acetylcholine, a neurotransmitter linked to improved brain health.
While cognitive training can be beneficial, experts emphasize that it is just one part of maintaining overall brain health. A healthy diet, regular exercise, stress reduction, and quality sleep are also essential for preventing dementia.
