Interactive brain training game may help lower risk of Alzheimer’s and dementia, study finds

A specialized brain training game that challenges attention and reaction speed may help reduce the risk of Alzheimer’s disease and other forms of dementia, according to new long-term research.

The study followed more than 2,800 older adults who were part of the Advanced Cognitive Training for Independent and Vital Elderly, or ACTIVE, trial. Participants tested different types of cognitive training, including memory exercises, reasoning tasks, and a computerized game designed to improve divided attention and processing speed.

Researchers found that only the fast-paced attention and speed training was linked to a reduced risk of dementia over time. Participants who completed the initial training and additional booster sessions experienced about a 25 percent reduction in dementia diagnoses compared with those who received no training.

The interactive game requires users to identify visual targets quickly while also tracking details in their peripheral vision. As performance improves, the game becomes more challenging, continuously pushing the brain to adapt.

Scientists believe this type of training may strengthen connections across the brain, build cognitive reserve, and improve the brain’s ability to function despite age-related changes or disease. However, experts say more research is needed to confirm exactly how the training influences long-term brain health.

Researchers also stress that brain training alone is not a complete solution. Maintaining cognitive health typically involves a combination of healthy habits, including regular exercise, balanced nutrition, quality sleep, stress management, and social engagement.

The findings suggest that targeted cognitive training may play a helpful role as part of a broader strategy to support brain health as people age.
