Aging is part of the life process, and we have to face it and accept it.
As we all know, maintaining a healthy life>
After all, in the face of knowledge, we often play the role of the weak.
Endless learning can always expand cognitive reserves, keep people thinking clearly and sharply, and prevent Alzheimer's disease.
Moreover, the general opinion also believes that the higher the level of education, the slower the brain aging.
However, is this really the case? Just now, in a new study published in the Proceedings of the National Academy of Sciences (PNAS), an international research team led by the University of Oslo in Norway found through brain scans of more than 2,000 people that education level can delay aging of the brain and There is no protection.
Over time, people with higher education levels lose brain tissue as quickly as others.
In short, in the face of shrinking brain tissue, almost everyone is equal.
However, the higher the level of education, the better the brain can be protected from the risk factors of dementia.
We know that the higher the level of education, although it does not mean the stronger the ability, it is indeed related to many results that are conducive to personal development.
Over the years, many studies have shown that education may slow down the decline in memory and thinking ability due to age.
However, those conclusions lack strong evidence provided by large longitudinal studies.
In this new study, the researchers investigated whether the level of education is related to an objective sign of brain aging, that is, brain tissue shrinkage.
To this end, they used data from two independent databases, LifeBrain and the UK Biobank, from 2024 participants aged 29 to 91.
During the 11-year follow-up period, all participants received at least two MRI brain scans.
The researchers used scans across the cortex and hippocampus to compare the rate of shrinkage of specific parts of the brain in people with and without higher education before the age of 30.
Longitudinal analysis of LifeBrain (1844 scans) showed that there is no obvious relationship between the level of education and the change in the apex volume of the entire cortex.
Similarly, when limiting the analysis to areas where the older the age, the greater the volume loss, it was not found that the higher the education level is related to the smaller the volume loss.
Moreover, the researchers found a reduction in hippocampal volume that was significantly associated with age.
Most importantly, the rate of change of hippocampal volume is not affected by the level of education.
Longitudinal analysis of the British Biobank (2578 scans) showed that with age, the posterior joint cortex and the areas of the lateral and medial frontal and temporal cortex showed more changes, but the level of education did not affect these cortex The rate of change of the region.
Therefore, a longitudinal analysis of two independent databases shows that there is no obvious link between education level and delaying brain atrophy.
However, Claire Sexto, head of the science project at the Alzheimer’s Association who was not involved in the study, said that the study provided important information.
It did not underestimate the other benefits of education to the brain, nor did it question the previous level of higher education.
Research linked to reduced risk of dementia.
Sexto explained that one theory is that education does not prevent aging-related brain changes, but helps people better adapt to these changes.
There is also a view that well-educated people may have more "cognitive reserves", which means that even if the brain tissue itself is aging, they can maintain more intelligence.
Sexton said that in addition to cognitive reserve theory, education may also have other indirect benefits.
It protects people from dementia risk factors to a certain extent.
For example, the effects of cardiovascular disease, high blood pressure and diabetes are also associated with a higher risk of dementia.
A well-educated person may have a higher income, a healthier diet, more exercise opportunities and better cardiovascular health.
The researchers said that the results of this study do provide different insights into the idea that education can delay brain aging, but it conveys a broader message.
Currently, the Alzheimer's Association is funding an experiment to better understand which specific measures can help delay or prevent Alzheimer's disease.
The study tested whether a range of life>
These measures include physical exercise, better control of high blood pressure and diabetes, and mental stimulation activities.
Sexton pointed out that people should take these measures as soon as possible.
It is never too late to develop a healthy life>
