"A study published in Alzheimer's & Dementia involving nearly 3,000 participants aged 65+ found that those who played the free speed-training game 'Double Decision' (available on BrainHQ) with booster sessions had a 25% lower risk of dementia over 20 years. The game, which improves processing speed, was the only one among three brain-training types to show a significant effect. Experts note the need for broader brain-health strategies."
