Brain Health Can Improve at Any Age, Large-Scale Study Finds
A three-year study of 3,966 adults aged 19–94 found brain health can improve with brief daily brain-training exercises, challenging the notion that cognitive decline is inevitable with age. Using the BrainHealth Index, researchers tracked gains in clarity, emotional balance, and connectedness; engagement was the strongest predictor of improvement, with the largest gains among those starting with lower scores. The study notes diversity limitations and includes ongoing brain imaging to explore neural mechanisms, underscoring that cognitive health can be cultivated at any age.
