We live in an era where average life expectancy is constantly increasing. Modern longevity science, however, stopped asking how long we will live a long time ago. Today's key question is: In what condition will we live the second half of our lives? Longevity without a functional brain, sharp focus, and a strong memory lacks meaning.
While wrinkles on the skin are instantly visible in the mirror, brain aging happens silently and gradually. Yet, we hold the power to fundamentally slow down this process. The key to a biologically youthful mind is a phenomenon called cognitive reserve – a mental "shock absorber" that each of us can build.
What is cognitive reserve and why do you need it?
Imagine two people aged 75. According to CT scans, both have a certain amount of age-related wear and tear in their brains. The first forgets names, struggles with spatial orientation, and loses their train of thought mid-sentence. The second drives a car with ease, learns a foreign language, and keeps their younger colleagues on their toes.
How is this possible? The second person has a robust cognitive reserve.
Cognitive reserve is the brain's ability to improvise and find alternative ways to solve a task when some common neural pathways are worn out by aging. It is like having a dense network of detours in your brain. When the main road gets blocked, a brain with a high reserve immediately finds a side route, and you won't notice any disruption at all.
Science Speaks: What Have Global Studies Revealed?
The myth that brain cells only die off after thirty has long been debunked by science. The human brain can create new connections and even new neurons (i.e., neuroplasticity and neurogenesis) at any age. However, it requires the right stimuli.
- 1. Study from the University of Cambridge: The Power of Novelty
Scientists from the University of Cambridge have long demonstrated that the brain ages significantly slower when exposed to an adaptive load. If you do things you already know how to do (for example, solving the same type of crossword puzzles over and over), the brain runs on autopilot and does not develop. However, the moment you challenge it with a task that dynamically adapts to its capabilities and forces it to overcome mild resistance, new neural synapses begin to form.
💡 TIP FOR YOUR LONGEVITY:
Don't put off taking care of your brain until old age. Just like with financial savings, the rule of compound interest applies to cognitive reserve – the sooner you start systematically investing in your mind, the longer it will stay in top condition.
Mentem as a gym for cognitive longevity
We have built the new generation of Mentem precisely on these scientific foundations. It is not just a set of random computer games. It is a comprehensive training system, where an adaptive algorithm constantly responds to your current performance and sensitively shifts the difficulty of tasks.
Each 15-minute exercise on Mentem forces your brain to step out of its comfort zone, measures your reaction time, error rate and accuracy. Thanks to the new Mentem Index, you no longer have to guess how you are doing – you can see accurate data on the state of your cognitive freshness over time.
Regular brain training is the first and essential step on the path to longevity. But the mind doesn’t live in isolation from the body. In part two, we’ll look at the “holy trinity of longevity” – how to combine brain training with exercise and diet, and why your gut is key to how sharp you’ll be in your 80s.¨
