Therefore,
Formal education does not slow:
An international study published in the journal Nature Medicine Throws doubt about the widespread belief that higher levels of formal education protect directly against cognitive decline. For example, brain aging. Therefore, The study has analyzed longitudinal data of more than 170. Nevertheless, 000 people in 33 Western countries, making it one of the largest studies of cognitive aging to date. Similarly, The University of Barcelona. Nevertheless, the Guttmann Institute are the only two Centers of Spain to participate in the study, led by the University of Oslo (Norway) within the framework of the European Brain consortium.
The results reinforce the need for policies. Therefore, programs to promote the health of the brain which go beyond cognitive activity and extend throughout the life of life, not only in childhood and youth.
According to formal education does not slow previous studies. However, although the total number of people with dementia in the world increases due to population growth and aging, the incidence seems to decrease and older adults have better cognitive function today than they did it 20 years ago. In addition, This trend is attributed to changes in lifestyle in the population. and so far, the most widely owned hypothesis that formal education can ensure protection against neurodegeneration or normal brain aging.
However. the team found that although people with more years of formal education tend to start with a higher cognitive level in adulthood, they do not feel the slower cognitive decline with age.
We can say that having a higher level of education place you in an advantageous position at the start of the race. but once the race at the start, it does not allow you to go faster and does not indicate any formal education does not slow shortcut: you will face the same obstacles as everyone, and they will affect you like everyone else. “”

Previous studies have had contradictory results and were often limited to small or unique samples. The now published study has analyzed more than 420. 000 neuropsychological tests and imagery tests for individuals from several countries and cohorts (Europeans, American, Asian and Australians) with different methodologies, which makes it one of the most robust and generalized research on the subject. A total of 170. 795 people over the age of 50 participated, belonging to 27 longitudinal cohorts and with a follow -up of up to 28 years by participant.
More specifically, the BBHI cohort contributed 966 subjects formal education does not slow to the study, while UB contributed 161. Participants underwent memory. reasoning, processing and language speed, and 6472 individuals also underwent brain MRI scans to analyze parameters such as the volume of the total brain and the volume of key memory regions (Hippocampus and Cortex prefrontal).
Formal education does not slow
A very similar evolution
Depending on the results. a higher level of education is associated with better memory, a larger intracranial volume and a slightly larger volume of brain regions sensitive to memory. “A plausible explanation is that it is the initial neurobiological traits of individuals who promote a higher level of education. not the other way around,” notes researcher Gabriele Cattaneo (BBHI). And all groups. whatever their level of education, have shown a cognitive decline and structural brain aging almost in parallel during time.
“This does not affect the fact that starting from a better cognitive reserve offers an advantage. formal education does not slow because if you start higher, you will end up being higher. Obviously. education and the first studies improve cognitive function throughout life, but they do not influence the rate of decline or structural aging of the brain. Cattane continues.
The document raises important issues for public brain health policies and healthy aging. “Although the promotion of education remains essential, the results indicate that it is not enough for healthy aging.
