Scientists at the University of Texas at Dallas studied how brain health changes over time. They followed almost 4,000 people, ages 19 to 94, for three years.
Each participant spent just five to fifteen minutes a day on simple mental exercises. The researchers used a special test called the BrainHealth Index (BHI) to see how people’s brains were doing.
The BHI looks at three things: how clear thoughts are, how steady emotions feel, and how connected a person feels to others and their purpose.
Results showed that brains can keep getting better, even in the 80s. People who started with low scores improved the most, but even those who began with high scores got a boost.
What mattered most was how often participants did the exercises. Age, gender, or education did not decide who improved.
The study group was mostly white, female, and college‑educated, so the researchers want to include more diverse participants in the future.
One researcher explained, “Every brain is unique, like a fingerprint, and it can grow. This work shows that brain health is something we can actively shape, not just accept as it is.”
Beyond the daily tasks, about 400 volunteers also had brain scans. These images help scientists link the BHI scores to real changes in the brain.
The project continues to collect data, hoping to learn more about how everyday habits can keep our minds sharp throughout life.
