Can brain training smartphone apps and computer games really help you stay sharp?

The Harvard Health article evaluates the effectiveness of brain-training apps and computer games in enhancing cognitive function. It notes that while these programs are marketed to improve memory and mental sharpness, scientific evidence supporting their efficacy is limited. Some studies indicate potential benefits, such as improved processing speed and working memory, but these findings are often undermined by methodological flaws. Moreover, the Federal Trade Commission has penalized companies for unsubstantiated claims. The article suggests that traditional activities like reading, playing cards, or engaging in new hobbies may be more effective in maintaining cognitive health. Given the current evidence, incorporating diverse, mentally stimulating activities into daily life is recommended over relying solely on brain-training apps.
