Dual n-back training boosts verbal memory in ADHD adults

New study finds dual n-back training improves verbal memory in ADHD adults, linked to IQ performance.

Why it matters

  • Dual n-back training improves verbal working memory in people with ADHD.
  • This could help enhance cognitive functions closely linked to IQ test performance.

By the numbers

  • 106 participants: 33 non-medicated ADHD, 42 medicated ADHD, and 45 controls.
  • Training lasted at least 18 daily sessions within one month.
  • Adaptive training showed a 204.6% improvement in controls, with a Cohen’s d effect size of 1.85.

The big picture

  • Adaptive dual n-back training significantly improves verbal working memory.
  • Transfer benefits to visuospatial domains are limited.
  • Training protocols should be tailored to maximize cognitive outcomes.

What they're saying

  • Short-term memory improvements are evident, but long-term transfer to everyday tasks is less certain.
  • Similar findings were reported in a 2017 study by Hopkins.

Caveats

  • Transfer benefits may not generalize to adolescents, older adults, or individuals with complex clinical profiles.
  • Study conducted on young adults with ADHD without psychiatric comorbidities.

What’s next

  • Further research could explore long-term transfer effects and applicability to other age groups and clinical profiles.
