Your brain can keep improving into your 90s, study finds
News
– The University of Texas at Dallas
– A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.
A new three-year study from researchers at The University of Texas at Dallas’ Center for BrainHealth (CBH) suggests that getting older does not automatically mean losing mental sharpness. Instead, the findings indicate that brain health and cognitive abilities can continue to improve throughout life.
Details
The research, published in Scientific Reports, a Nature journal, draws on data from The BrainHealth Project (BHP), an initiative launched by CBH in 2020 to better understand how people can strengthen and optimize brain health across the lifespan.
Researchers tracked 3,966 adults ranging in age from 19 to 94. This group represented roughly one-fifth of all BrainHealth Project participants. Over the course of three years, participants completed brief training activities that required only five to 15 minutes per day.
BrainHealth Index Tracks Changes Over Time
Analysis
To evaluate changes in brain health and performance, the team used the BrainHealth Index (BHI), a patent-pending assessment developed by CBH researchers and first introduced in a 2021 pilot study.
The BHI is designed to detect both improvements and declines in brain health. It measures three primary areas: clarity, emotional balance, and connectedness to people and purpose.
“The BrainHealth Index brings together about 20 metrics, including validated gold-standard measures like the Pittsburgh Sleep Quality Index and the Oxford Happiness Questionnaire, as well as tasks designed at the Center for BrainHealth to focus on more complex thinking skills,” said Lori Cook MS’02, PhD’09, CBH director of clinical research and corresponding author of the Scientific Reports study. “This battery of assessments produces insights into individual brain health and change over time.
