Brain health can grow at any age with online training, new study finds

A three-year online BrainHealth Project study of 3,966 adults aged 19–94 found that adults of all ages can measurably improve brain health using accessible online training and coaching. The BrainHealth Index showed gains across cognitive clarity, social connectedness, and emotional balance, with higher engagement yielding larger improvements. Importantly, those starting with lower brain health scores improved the most, and there was no observed ceiling to growth, challenging the idea that cognitive vitality is limited to seniors. Limitations include lack of a control group and a highly educated sample; researchers plan to add objective health metrics and a more diverse population in future work.
