Neuroplasticity Lasts a Lifetime: Brain Health Improves Across Adulthood, Study Finds

A three-year UT Dallas study of 3,966 adults aged 19–94 found brain health can improve at any age with just 5–15 minutes of daily brain-training, as measured by the BrainHealth Index across clarity, emotional balance, and connectedness; the biggest gains came from those starting with the lowest scores, and engagement level was the strongest predictor of improvement, challenging the idea that cognition inevitably declines with age. The study notes representativeness limits in its sample and ongoing imaging research continues to explore underlying brain mechanisms.
