Alzheimer's & Dementia: Translational Research & Clinical Interventions, 2026

ACTIVE Trial — 20-Year Follow-Up

Speed-of-processing training with booster sessions showed a 25% reduction in dementia risk over ~20 years in older adults.

Scientific Reports (Nature), 2020

Commercial Cognitive Games Meta-Analysis

Commercial cognitive games improve processing speed (SMD 0.50) and attention (SMD 0.43) in older adults across multiple studies.

Scientific Reports (Nature), 2021

Large-Scale Cognitive Training Study (12,000 users)

12,000 users aged 60-80+ improved cognitive performance and processing speed across 100 training sessions, regardless of age.
