Number Memory and ADHD

ADHD typically reduces effective digit span by 1-2 digits due to attention lapses during encoding. Training that emphasizes consistent encoding strategies and minimizes distractions yields significant gains.

Working memory is trainable — even with ADHD.

Why Adhd care about Number Memory

ADHD typically reduces effective digit span by 1-2 digits due to attention lapses during encoding. Training that emphasizes consistent encoding strategies and minimizes distractions yields significant gains.

Performance Drivers

Adhd typically need to emphasize:

  • Encoding consistency
  • Reducing internal distraction during memorization

Benchmarks & Interpretation

Compare your number memory scores against cohort averages to spot strengths or risks. Track both best-case and consistency metrics to ensure progress translates into competition.

Lifestyle Levers

Off-game habits move the needle. Start with these levers:

  • Medication timing relative to training
  • Exercise before training sessions
  • Minimizing environmental distractions

Training Playbook

Run focused BrainGames blocks 3-4 times per week. Pair drills with immediate application—scrims, study, or high-stakes work—to lock in gains.

  • Verbalization during encoding
  • Very short drill bursts (3-5 attempts, then break)

Integration & Review

Review metrics weekly with teammates or coaches. Tag lifestyle variables (sleep, travel, caffeine) so you can correlate them with performance swings.

Questions about this benchmark

Should I train on or off medication?+

Train both ways. Medicated sessions build peak performance; unmedicated sessions build raw strategies. Track your scores separately to understand your range.
