Memory tends to change with age, but significant memory loss and cognitive decline are not inevitable parts of ageing. Research consistently shows that lifestyle factors you control now can significantly support your cognitive health in your sixties, seventies, and beyond. Here are ten evidence-based strategies that may help protect memory and support brain health as you age.
1. Stay Physically Active
Physical exercise is one of the strongest tools available for supporting memory and cognitive function. Regular aerobic activity is associated with increased blood flow to the brain, supports the growth of new brain cells, and strengthens connections between existing ones. Even moderate activity like brisk walking for 30 minutes most days may benefit your brain. Strength training adds further benefits for cognitive health.
2. Maintain a Healthy Diet
What you eat affects your brain. The Mediterranean diet, which emphasises fish, vegetables, whole grains, olive oil, and nuts, has strong research support for protecting memory and is associated with reduced dementia risk. Omega-3 fatty acids found in fish and walnuts support brain health, and antioxidants in berries and leafy greens may help protect brain cells from damage.
3. Engage Your Mind
Mental activity keeps your brain engaged and helps maintain cognitive reserve, your brain's ability to improvise and find alternative ways to get a job done. Activities that challenge your mind include learning something new, puzzles, reading, writing, learning a language, or taking a class. The key is continuous mental engagement, not just doing the same familiar tasks.
4. Get Quality Sleep
Memory consolidation, the process by which new information is stored and strengthened in your brain, happens primarily during sleep. Poor sleep disrupts this process and is associated with cognitive decline. Prioritising sleep is essential for memory protection.
5. Manage Stress
Chronic stress is associated with damage to the hippocampus, the brain region central to memory formation. Practising stress-reduction techniques like mindfulness meditation, deep breathing, tai chi, or yoga may help protect against stress-related cognitive decline.
6. Maintain Social Connections
Social engagement is surprisingly protective for cognitive health. People with strong social connections tend to have slower rates of memory decline. Regularly spending time with friends and family, joining clubs or groups, or volunteering all provide cognitive stimulation and emotional wellbeing.
7. Control Blood Pressure and Cholesterol
High blood pressure and elevated cholesterol are associated with increased dementia risk through damage to small blood vessels in the brain. Working with your GP to maintain healthy levels of these risk factors helps protect brain health. Take blood pressure and cholesterol-lowering medications as prescribed.
8. Manage Blood Sugar
Diabetes and poor blood sugar control are associated with increased dementia risk. If you have diabetes or prediabetes, work with your healthcare team to manage blood sugar well. Even if you do not have diabetes, a healthy diet and regular activity help maintain healthy blood sugar, which supports brain health.
9. Challenge Yourself
Learning something completely new, such as a musical instrument, a language, or a new skill, challenges your brain in ways that may help maintain and build cognitive function. The challenge is what matters; the activity should be somewhat difficult and require focused attention.
10. Avoid Smoking and Limit Alcohol
Smoking damages blood vessels throughout the body, including in the brain, and is associated with significantly increased dementia risk. If you smoke, quitting is one of the most beneficial things you can do for your brain. Whilst moderate alcohol consumption may have some neutral or protective effects, excessive drinking is associated with brain damage. Limit alcohol to no more than one standard drink a day for women or two for men.
Memory Changes That Are Normal
It is important to distinguish between normal age-related memory changes and signs of cognitive decline. Normal changes include occasionally forgetting names or appointments, misplacing glasses, or needing to concentrate harder to learn new information. These are experienced by virtually everyone and are not signs of disease.
When to Seek Help
Seek evaluation if you or someone close to you notices memory loss that interferes with daily functioning, trouble handling familiar tasks, getting lost in familiar places, or repeatedly asking the same questions. These may signal cognitive decline that warrants professional assessment.
A Practical Step You Can Take This Week
Pick the one strategy from this list you have not been doing consistently, and turn it into a small daily habit, perhaps a 30-minute walk, a phone call with an old friend, or a 10-minute language app session. Cognitive reserve is built one ordinary day at a time.
