Speed Training Halves Dementia Risk: Study
11 Mar
Summary
- Speed training boosted dementia risk reduction by 25%.
- Booster sessions were critical for sustained benefits.
- Memory and reasoning training showed no dementia protection.
A significant study published in February 2026, tracking 2,000 older adults over two decades, has identified a promising intervention for reducing dementia risk. The research focused on three types of cognitive training: memory, reasoning, and speed. Participants engaged in 10 sessions over six weeks, with a subset receiving additional booster sessions at 11 and 35 months.
Twenty years after the initial training, findings indicated that individuals who completed speed training and received booster sessions showed a remarkable 25% lower risk of being diagnosed with dementia. The neurologist overseeing the study emphasized that the booster sessions were crucial; those who only completed the initial speed training without follow-ups saw no benefit.
Memory and reasoning training, even with boosters, did not demonstrate any significant protection against dementia. This suggests that the adaptive challenge provided by speed training, combined with sustained engagement through booster sessions over a long period, is key to its efficacy. The principle mirrors physical exercise, where increased resistance is necessary for continued progress and adaptation.
