How to practice Most commercial “brain games”
If you use brain games, favor tools with some independent evidence of benefit beyond in-game scores, not just marketing claims. Programs like BrainHQ are better studied than most and show improvements in specific skills (e.g., processing speed), though benefits are modest and task-specific. Use brain games as a supplement, not a core strategy, and pair them with higher-value activities like learning new skills, physical exercise, or social engagement.
The evidence behind Most commercial “brain games”
Mechanism: practice improves the specific trained task; far transfer to everyday cognition is limited. Evidence quality: meta-analyses show reliable near-transfer, minimal or no far-transfer; no convincing data for dementia prevention or durable executive gains. Who & when: benefits are mostly on the leaderboard, not in life; older adults may see small task-specific gains. Nuance: marketing overreach is common; opportunity cost versus richer learning or exercise is high.
