Practice can
- Help you get better at what you practice.
- Give your day a routine you enjoy.
Practice cannot
- Promise to protect your memory or thinking.
- Tell you whether your memory is healthy.
What practice does
You get better at what you practice. Studies of brain-training programs find that people improve on the tasks they practiced, with less evidence for similar tasks and little for different tasks or everyday life (Simons and others, 2016).
For healthy older adults, a review of computer-based training found small benefits right after training, from low-quality evidence (Cochrane review, 2020). The World Health Organization says cognitive training may be offered to older adults, though the evidence is still low certainty (WHO, 2026).
Practice can also be a routine you enjoy: a few minutes at your own pace that keep your mind busy and challenged.
What it cannot promise
No practice, here or anywhere else, has been shown to prevent dementia or to reverse a decline in memory or thinking.
Your results describe these activities, not your overall brain health. QuickenBrain is not a medical test and does not diagnose anything.
What research links to brain health
These findings are about everyday habits, not about QuickenBrain, and they are not medical advice.
- Moving. For adults with normal memory and thinking, the World Health Organization gives physical activity a strong recommendation, and cognitive training only a conditional one (WHO, 2026).
- Hearing care. Hearing loss is one of 14 risk factors for dementia that people may be able to change (Lancet Commission, 2024). In one large trial, memory and thinking changed about as much over three years with hearing care as without it, though it might help people at higher risk (ACHIEVE, 2023).
- Blood pressure and not smoking. High blood pressure and smoking are on the same list of 14.
- Time with people. Social isolation is on the list too.
- Learning new things. The World Health Organization says everyday activities that keep the mind busy, such as reading, may be encouraged, though the evidence is very low certainty (WHO, 2026).
When to talk to a doctor
This is not a medical test. If you or someone close to you is worried about memory or thinking, talk to a doctor.
