Speed-focused brain training linked to 25% dementia risk drop, study finds
A 20-year study of 2,800 healthy older adults found that speed-based brain training (Double Decision by BrainHQ) with booster sessions reduced dementia risk by about 25% compared with no training, while memory and reasoning training did not. The authors suggest a mechanism in procedural learning, but caution that results may not generalize to everyone and depend on ongoing training and boosters, among other factors in brain health strategies.
