Your brain shapes how you navigate life. Brain health means keeping your brain working its best as you age. Maintaining a healthy brain protects how well you think, learn and remember — and may also help lower your risk of dementia.
Taking care of your brain is important at every age, not just in the later stages of adulthood or when concerns about memory arise. That means the actions you take today, along with how you manage your overall health, matter.
Learning more about what influences brain health can help you find practical ways to support yours with habits that fit into your life.
There’s more than one way to keep your brain healthy. How you eat, move, sleep, challenge your mind and monitor your health all play a role in building a brain-healthy lifestyle and may help lower the risk of cognitive decline and possibly dementia. Research shows that the best recipe for brain health is a combination of all these habits working together.

Fuel your brain with nutrient-rich foods and a balanced diet, then find small ways to make healthier eating part of your daily routine.

Regular physical activity helps improve brain function. Find enjoyable ways to move more, build consistency and track your progress.

Keep your mind active and curious by learning new skills, exploring unfamiliar hobbies or choosing activities that make your brain work differently.

Quality sleep on a regular basis supports your brain health. Learn your sleep patterns and practice good sleep hygiene to experience better sleep.

What's good for your heart is good for your brain. Know your numbers and build healthy habits that support your overall health and brain health.

Protecting your head from injury is important for brain health at any age. Always wear a helmet and seatbelt when appropriate and learn how to help prevent falls.

Better brain health starts with better science. As a global leader in brain health research, the Alzheimer's Association is advancing what we know about risk reduction for cognitive decline and dementia and the lifestyle factors that protect brain health.
At the heart of that work is the Alzheimer's Association U.S. POINTER Study, a landmark clinical trial showing that combining healthy lifestyle behaviors can help protect our brains. (re)think your brain brings insights like these into everyday life, turning the latest science into practical, achievable steps. It's all part of helping people understand that brain health is something they should think about earlier, act on every day and support through healthy habits that fit the way they actually live.
See how this landmark Association-led study demonstrates the cognitive benefits of combining multiple healthy lifestyle behaviors.
The Alzheimer's Disease Facts and Figures 2026 Special Report examines how Americans understand, prioritize and act on the desire to sustain brain health across the lifespan.
