One of the greatest forms of wealth in life is the ability to remember the moments we share with the people we love. Memories shape our identity, preserve our relationships, and give meaning to our experiences.
Memories and Brain Health
Today, approximately 60 million people worldwide are living with Alzheimer’s disease and other forms of dementia. This number is expected to exceed 110 million by 2050.
Alzheimer’s is not simply a consequence of ageing. Scientific research increasingly shows that lifestyle plays a critical role in brain health.
The encouraging news is that there are evidence-based strategies that can support cognitive function and potentially reduce the risk of neurodegeneration.
Below are six scientifically supported approaches to help protect your brain:
1. Preserve Your Muscle Mass
Resistance training—especially exercises targeting large muscle groups such as the legs—does more than build strength.
Muscle tissue is metabolically active. As muscle mass increases:
- Insulin sensitivity improves
- Blood circulation increases
- Production of Brain-Derived Neurotrophic Factor rises
BDNF supports the formation of new neural connections and strengthens existing ones.
Research also shows that muscle loss (sarcopenia) is associated with cognitive decline.
Maintaining muscle mass is not about appearance—it is an investment in brain resilience.
2. Step Outside Your Comfort Zone
Small changes in daily routines stimulate neuroplasticity.
For example, brushing your teeth with your non-dominant hand challenges the brain in new ways. These activities enhance communication between the two hemispheres and promote new neural pathways.
Neuroplasticity—the brain’s ability to reorganise itself—is essential for maintaining cognitive flexibility as we age.
3. Write by Hand and Read Regularly
Handwriting activates multiple brain regions simultaneously, including motor, language, and memory centres.
Regular reading increases “cognitive reserve”—the brain’s ability to compensate for age-related changes.
Individuals with higher cognitive reserve often show delayed onset of dementia symptoms.
In a digital world, returning to pen and paper can be a powerful cognitive tool.
4. Seek Novel Experiences
Travelling and exploring new environments activate the hippocampus, the brain region responsible for memory formation.
Novel experiences:
- Increase dopamine release
- Strengthen synaptic connections
- Promote neural adaptability
Exploring new places and cultures is not just leisure—it is neurological enrichment.
5. Prioritise High-Quality Sleep
During sleep, the brain activates the Glymphatic System, which removes metabolic waste, including beta-amyloid and tau proteins.
Insufficient sleep:
- Disrupts this process
- Increases inflammation
- Elevates cortisol levels
Chronic sleep deprivation is strongly linked to increased Alzheimer’s risk.
Protecting sleep is one of the most powerful ways to support brain health.
6. Train Coordination
Simple coordination exercises—such as throwing a tennis ball between hands for 5–10 minutes daily—stimulate both sides of the brain.
Benefits include:
- Improved reflexes
- Better balance
- Faster processing speed
- Stronger inter-hemispheric communication
These exercises are especially beneficial as we age and can easily be done at home.
Additional Risk Factors to Be Aware Of
Several lifestyle-related factors are linked to increased Alzheimer’s risk:
- Chronic inflammation
- Insulin resistance
- Physical inactivity
- Highly processed diets
- Social isolation
- Chronic stress
- Cardiovascular disease
Metabolic health and brain health are deeply interconnected.
Final Thought
Alzheimer’s is not an inevitable destiny. A metabolically strong body supports a resilient brain.
The greatest wealth we possess is not material—it is the memories that allow us to recognise, connect with, and cherish the people we love.
