Older adults who did speed-of-processing training had 25% lower dementia risk after 20 years, per a NIH-funded study.
A 20-year follow-up of a NIH-funded study found that older adults who completed speed-of-processing training—especially with booster sessions—had a 25% lower risk of dementia, with 40% diagnosed compared to 49% in the control group.
The training, involving adaptive computer exercises like the game Double Decision, focused on improving visual processing and attention.
Only this intervention showed a significant, lasting reduction in dementia risk, including Alzheimer’s and other types, over two decades.
Researchers suggest the benefit may stem from implicit learning, which engages different brain pathways than memory or reasoning training.
The findings, based on Medicare data from nearly 2,000 participants, offer strong evidence that brief, consistent cognitive training could delay dementia onset and reduce long-term healthcare burdens.
