In recent years, the claim that the brain is like a muscle is popular: if not studied, these are atrophies. As a result, solving problems, puzzles, sudoku and so on. Implementation of the brain through. This has been announced as a way to minimize the risk of suffering from senile dementia or Alzheimer's disease, not to minimize the age-related intellectual decline.
However, scientific proof of neuroscience supporting the above-mentioned statements is very weak. Neevropatologist and Teacher at Yale University Medical School Steven Novella explains: "Two decades of research suggests that you are more capable of acting in a particular mind, and if you make a sudoku, you will be better off sudoku solution and will not be easier. "
However, these neurological findings have not been a barrier to the "brain education" industry in the form of books, video games, music, courses … In fact, a cognitive assessment of a sector report, by 2022, brain education is more than $ 8 billion in the world. And, as always, marketing is just ahead of science, if it does not shake directly.
Recently published in a medical journal English Medicine JournaIt also adds another mandate to suspect brain training. Researchers from the University of Aberdeen and the National University of Ireland have watched 498 volunteers for 15 years. All the participants shared a number of details: they were born in 1936 and live independently in the north-east of Scotland and have previously been involved in a mental health survey in that country in 1947. linking the age-related level of mental activity and evaluating the volunteer mental activity and their performance over time.
The results of the research show that people with more mental functions throughout the lifetime have superior cognitive ability. In spite of everything, it is impossible to know the cause and the way of learning. The clever think that they are more intelligent (logical) or vice versa, they are clever because they are mentally active. However, the main purpose of the research problem is that it does not relate to a lowering of cognitive impairment in later life compared to a lower incidence of mental activity.
In other words, as the age decreases, cognitive abilities, as well as active active and passive volunteers, have suffered the same intellectual decline (especially memory problems and processing speeds). However, those who have been active throughout their lifetime have had a superior cognitive ability that allows them to gain more time with better cognitive functions. The authors of the study explain: "These results show that the individual individual decline in problem solving is not protected, but the decline is higher than the initial starting point, and the disability is significant."
It recalls previously documented chess players. When suffering from Alzheimer's disease, the effects of life are generally less than normal. They have clinical skills superior to their mental activity to protect them from dementia or to far away Alzheimer's best symptoms. A chess player who was crippled with a soft cognitive disorder in the last years of his life was excited. When he died, doctors discovered that in splitting, the very fact that Alzheimer's had developed in his brain was actually shown.
Of course, the limitations of such studies are always taken into account. Of course, the strongest research is the 15-year follow-up of 500 people. Nonetheless, this is an observer's research (no intervention by volunteers on the habits of volunteers) that hinders us from describing the causes and effects. Instead, we can only create correlation and general outcomes. However, the moral aspect of the story is clear: If you are clever and have had a rich life in learning and different mental activities, you will probably start with a higher cognitive function that will not slow down your mental retardation, but you will start with a more privileged situation. and symptoms will take longer to show. Now, mental training through certain activities at a certain age is not a magic solution to compensate for all previous mental laziness.
