⚖️ Mental Age vs Real Age
Understand what your mental age truly reveals
📖 Two ages, two different measurements
We all have a chronological age: the number of years since we were born. But have you ever met a 70-year-old more lively than a 40-year-old? This is where mental age comes in.
| Criteria | Chronological Age | Mental Age |
|---|---|---|
| Definition | Time elapsed since birth | Cognitive performance level |
| Measurement | Simple calculation (years) | Standardized cognitive tests |
| Evolution | Always increases (+1 year/year) | Can increase, stagnate or decrease |
| Influenced by | Nothing (objective) | Lifestyle, training, health |
| Modifiable | No | Yes, in both directions |
💡 In summary: Your chronological age tells you how long you have lived. Your mental age tells you how your brain functions compared to typical performances at different ages.

▶️ Take the test🔬 How is mental age measured?
Mental age is calculated by comparing your cognitive performance to those of reference groups of different ages. The tests assess several abilities:
- Short-term memory - Retain information temporarily
- Processing speed - Speed of reaction and thinking
- Working memory - Mentally manipulate information
- Executive functions - Plan, inhibit, adapt
- Attention - Focus and filter distractions
These abilities evolve predictably with age. For example, processing speed peaks around 20-25 years and then gradually declines. If a 50-year-old scores comparably to an average 35-year-old, their "mental age" is 35 years.
The norms used are derived from studies involving thousands of participants of all ages. These data help establish typical performance curves for each age group.
📊 Interpret different scenarios
Mental age lower than actual age
What it means: Your brain functions like that of a younger person. Your lifestyle habits (exercise, cognitive stimulation, diet, sleep) likely have a protective effect. Keep it up!
Mental age close to actual age
What it means: Your brain is aging normally and harmoniously. This is the most common result and there is no cause for concern. Maintain your good habits.
Mental age slightly higher (+5-10 years)
What it means: Some cognitive functions might benefit from training. It can also reflect fatigue, stress, or a lack of cognitive stimulation. It is reversible with the right habits.
Mental age considerably higher (+15 years or more)
What it means: A significant gap deserves attention. It may be due to modifiable factors (stress, sleep, sedentary lifestyle) or sometimes early signs requiring medical advice. Consult if this gap persists.
A one-time score may not necessarily reflect your actual state. Fatigue, stress, distractions can skew results. Retake the test under good conditions before drawing conclusions.
🎯 Factors influencing the gap
Factors that "rejuvenate" the brain
Regular exercise
Sport increases cerebral blood flow
Cognitive stimulation
Games, learning, reading
Good sleep
The brain regenerates at night
Healthy diet
Omega-3, antioxidants, vitamins
Active social life
Interactions stimulate the brain
Stress management
Meditation, relaxation
Factors that "age" the brain
Sedentary lifestyle
Lack of exercise reduces blood flow
Chronic stress
Cortisol damages the hippocampus
Poor diet
Sugars, saturated fats, ultra-processed foods
Lack of sleep
Prevents consolidation and "cleansing"
Tobacco and alcohol
Toxic to neurons
Intellectual passivity
The brain needs challenges
⚠️ Limitations and precautions
Mental age is a useful concept but has its limitations:
What mental age does NOT measure
- Overall intelligence - Mental age measures certain cognitive abilities, not "intelligence" as a whole
- Wisdom and experience - These qualities often increase with age
- Specialized skills - A 60-year-old expert surpasses a 25-year-old novice in their domain
- Creativity - Hard to measure and does not necessarily decline
Interpretation precautions
- An online test is not a medical diagnosis
- Results vary based on conditions (fatigue, stress, environment)
- Some people are simply less comfortable with timed tests
- Mental age does not predict the future - it is changeable
💡 Tip: Use mental age as a motivating indicator, not as a definitive label. It's a starting point to care for your brain, not a verdict.
