"Is what I'm noticing normal, or is it the start of something?"

It's a question many of us ask after forgetting a name, losing our train of thought, or watching a loved one struggle with memory. Just as quickly, we push it aside, because it feels easier than facing what the answer might mean.

Cognitive changes are common, and we're often reassured that forgetfulness is simply part of getting older. But understanding the difference between normal ageing and early cognitive decline can change how you think about your long-term brain health.

Common does not mean inevitable.

One helpful way to understand this is through psychiatrist Dr Daniel Amen's concept of Brain Reserve. He describes it as the extra brain function you have "in the bank", a buffer that helps you stay mentally resilient as life, stress, and ageing place increasing demands on the brain.

The greater your reserve, the more capacity your brain has to handle challenges like chronic stress, poor sleep, inflammation, metabolic strain, illness, toxin exposure, injury, and the gradual wear that comes with time.

When reserve is low, the same pressures feel heavier. Focus slips more easily, mood dips faster, anxiety increases, thinking slows, and memory becomes less reliable.

The encouraging part is that Brain Reserve is not fixed. Regardless of age, genetics, or personal history, it can be supported and strengthened.

Here are five practical ways to build Brain Reserve and protect your memory and mental wellbeing.

1. Improve Blood Flow to Your Brain

Healthy blood flow is essential for brain function. It delivers oxygen and nutrients, supports energy production, and helps clear metabolic waste that builds up during normal activity. Research consistently shows that reduced cerebral blood flow is linked to cognitive decline and a higher risk of dementia. In brain-imaging studies, lower circulation is also often associated with symptoms like brain fog, low motivation, and mood instability.

The good news is that circulation is one of the most responsive aspects of brain health. Small, consistent lifestyle habits can make a meaningful difference over time.

Practical ways to support healthy brain blood flow:

· Move your body daily. Even brisk walking supports circulation and oxygen delivery to the brain.
· Build cardiorespiratory fitness. Activities that gently raise your heart rate help strengthen vascular health.
· Stay well hydrated. Adequate fluid intake helps maintain healthy blood volume and circulation.
· Include nitrate-rich foods. Dark leafy greens like spinach, rocket, and beetroot support nitric oxide production, which helps blood vessels relax and widen.

2. Reduce Inflammation: The Slow Burn

Chronic, low-grade inflammation is often described as a "slow burn" in the body. Over time, it can affect brain function, energy levels, and overall resilience. One area researchers are exploring is how cellular energy pathways influence inflammation and healthy ageing.

One of the most studied NAD+ precursors is NMN (nicotinamide mononucleotide), a compound the body naturally uses to produce NAD+, a molecule involved in cellular repair and energy metabolism. Rather than acting like a stimulant, NMN supports processes your body already relies on to maintain balance at a cellular level.

Some people report steadier energy, improved focus, and greater day-to-day resilience when supporting NAD+ pathways. Not to force energy into the system, but to provide the building blocks that help cells function more efficiently.

As with any supplement, it's important to view NMN as one piece of a broader foundation that includes sleep, nutrition, stress management, and regular movement, all of which play a significant role in regulating inflammation over time.

3. Move, Connect, and Add Novelty

Studies on "SuperAgers", older adults with unusually strong memory, often point to one shared factor: meaningful social connection. Social isolation, on the other hand, is now recognised as a modifiable risk factor for cognitive decline.

A simple way to build Brain Reserve is to combine movement, connection, and novelty. Think dancing, hiking with friends, group classes, learning a new sport, or volunteering. These experiences challenge coordination, attention, emotion, and memory at the same time, giving your brain a richer and more protective workout.

4. Support Brain Energy – Think Metabolism

Dr Chris Palmer, author of Brain Energy, puts it plainly, "Mental disorders are metabolic disorders of the brain." In practice, your mood, focus and resilience are shaped by how well brain cells produce and manage energy. Metabolic health matters for longevity too. Large studies show that insulin resistance and type 2 diabetes are associated with a higher risk of dementia, including Alzheimer's disease.

Ways to support healthy brain energy:

· Know your markers: HbA1c, fasting insulin (or HOMA-IR), and triglyceride:HDL ratio.
· Flatten glucose spikes with protein-first meals, high fibre, fewer refined carbs.
· Train mitochondria with aerobic exercise and strength training each week.

5. Get Your Brain Assessed, Before it Forces You to

Most people only think deeply about their brain after something goes wrong. By then, the picture is often more complex and the path back can take longer. Assessment changes that. It allows you to act earlier and more preventatively by giving you a clear baseline, flagging risks you may not have considered, and translating symptoms into an evidence-informed, personalised pathway to better brain health and performance.

At NeuroVita, the NeuroVitals Assessment is designed as that first "brain check". It maps cognitive decline risk and the key brain systems that influence focus, mood, memory and stress, then turns the findings into a practical plan you can actually follow.

The Takeaway

Cognitive decline is common, but it isn't inevitable. More than protecting our brain from decline, we want to build capacity. Brain Reserve is that capacity: more healthy tissue, stronger function, and more flexibility under pressure. When you build it, life's stressors have a smaller impact on you. Over time, you give your brain a bigger buffer, and a better chance of protecting your memory and mental health as you grow older.
