Is mental training used to counter the intellectual decline associated with aging? – Journalism. with


During the last few years, the idea that the brain is like a muscle has become popular: if it is not trained, it atrophies. As a consequence, brain exercise through problem solving, puzzles, sudoku, etc. It has been disclosed as a method not only to minimize the intellectual decline that occurs with age but also to decrease the risk of suffering from senile dementia or Alzheimer's disease.

The reality, however, is that the scientific evidence in the field of neuroscience that supports the above statements is very weak. As Steven Novella, a neurologist and professor at Yale University School of Medicine, explains: "What more than two decades of research shows is that by performing a specific mental activity you become more skilled at that activity, and that's it. If you make a sudoku, you become better at solving sudoku, you do not get smarter. "

These neuroscience discoveries, however, have not been an obstacle to the booming industry of "brain training" in the form of books, video games, music, courses … In fact, a sectoral report predicts that the business of cognitive assessment and O Brain training moves more than eight billion dollars in the world until 2022. As almost always happens, marketing is ahead of science when it is not directly trampled.
