One of the most damaging assumptions about cognitive aging is that improvement stops at a certain age. A three-year longitudinal study of nearly 4,000 adults, published in Scientific Reports and covered by ScienceDaily on June 13, 2026, provides some of the most robust evidence yet that this assumption is wrong.
Researchers at the UT Dallas Center for BrainHealth tracked 3,966 adults aged 19 to 94 over three years and found that consistent engagement in targeted brain-health practices produced measurable cognitive improvements across every age group studied — with no upper ceiling of improvement detected and the greatest gains in those who started with the lowest scores.
