This large-scale study examined the effectiveness of commercial brain training programs, analyzing data from over 60,000 participants. Results showed that long-term brain training (over a year) led to small improvements in working memory and verbal ability but had negligible effects on reasoning skills or real-world functions like attention and employment. Other cognitive activities, such as puzzles and games, demonstrated stronger benefits. The study highlights that while brain training can improve specific skills, its broader claims are overstated.
Instead of relying solely on brain training, diversify cognitive activities to include puzzles, board games, or strategic video games, which have demonstrated stronger and broader cognitive benefits. Use brain training selectively for targeted improvements, keeping in mind its limitations as revealed by the study.
