A long-term study suggests that certain types of brain training may be linked to better cognitive health later in life.
Researchers followed nearly 3,000 adults aged 65 and older for 20 years. Participants who completed up to 23 hours of a cognitive āspeed trainingā program ā focused on improving visual processing and reaction time ā were found to have a 25% lower risk of developing dementia compared with those who did not receive the training.
Other types of exercises, such as memory or reasoning training, did not show the same results.
Experts note that dementia is influenced by many factors, and no single activity prevents it. Still, the findings add to a growing conversation about how small, consistent habits may support long-term brain health.
