UT Dallas Study Finds Brain Health Improves Into 90s in 3,966 Adults

Summary
A 3-year study of 3,966 adults aged 19 to 94 found measurable gains in brain health across all age groups, including people in their 80s and 90s.
Using the BrainHealth Index, researchers tracked changes in clarity, emotional balance and connectedness after participants spent just 5 to 15 minutes a day on training activities.
The biggest gains came from participants who started with the lowest scores, while engagement—not age, gender or education—was the strongest predictor of improvement.
The findings, published in Scientific Reports, challenge the idea of inevitable cognitive decline, though researchers said the mostly white, female and college-educated sample limits generalization.
The BrainHealth Project is continuing follow-up work, including more than 1,200 brain scans from about 400 Dallas-area participants to probe the neural basis of those changes.

BrainHealth Index Study Reveals Cognitive Improvement Possible at Any Age
Overview
A groundbreaking three-year study by the Center for BrainHealth at UT Dallas, published in May 2026, has challenged the belief that cognitive decline is inevitable with age. The research shows that brain health can improve at any stage of adulthood, even for people in their 80s and 90s. Notably, those who started with the lowest BrainHealth Index scores experienced the greatest improvements, highlighting the brain’s capacity for positive change. This study emphasizes neuroplasticity, suggesting that maintaining and enhancing brain function is about fostering growth and resilience, and that everyone can actively shape their cognitive future.
