How and how much does solving table and sudoku make your brain younger?

Study guide

According to new research, solving the puzzle helps strengthen the mind and brain health and prevents the weakening of cognitive skills. Research recently published in the World Journal of Aging Psychology shows that the more people over the age of 50 play games such as sudoku and crossword puzzles, the better their brain function. In this article, we research the effect of solving table and sudoku on health.

In a study of 19,100 participants, people who are accustomed to solving puzzles were presented with a variety of tests and asked to solve the tests. These tests were presented online to participants and they were asked to announce the results and changes. According to the findings, the more people are able to solve puzzles such as sudoku, the better they can handle all kinds of tests. According to the study, the brain function of people who are accustomed to solving puzzles is equivalent to the brain function of people who are at least 10 years younger than them. On the other hand, in short-term memory tests, the brain function of the mystics was equivalent to the brain function of people 8 years younger than them.

According to Dr. Ann Corbett, lead researcher and professor at Exeter Medical University, there is a clear improvement in the speed and accuracy of the work of participants who are interested in solving the puzzle. In some cases, this progress is significant.

Although we can not claim that solving such puzzles reduces the risk of dementia, this study confirms the results of previous research on the positive effect of solving puzzles and riddles on better brain function for longer years.

Researchers want to continue their research with the same participants over time. They also want to examine the relationship between the difficulty of puzzles and the amount of time it takes to solve the puzzle.

Evaluate research results

Dr. Jerri D. Edwards, a professor at the University of South Florida who studies mental games and cognitive abilities, believes that because the research method was correlational rather than random, mental games do not lead to cognitive function. They get better. According to him, “it is possible that people with better cognitive abilities will be more interested in these games.”

“Of course, people with weaker cognitive abilities also play these games, but when faced with cognitive weakness, they probably stop playing because of frustration,” he said.

According to Edwards, based on extensive randomized clinical trials, computer cognitive exercises aimed at speeding up processing over time have a better effect on preventing cognitive decline at older ages.

As Edwards puts it, ‚ÄúSome abilities, such as speaking skills, are enhanced with age. Therefore, as the brain ages naturally, our performance in word-based games improves. In other words, some cognitive skills weaken with age, including mental agility, simultaneous attention to several things, inattention to distraction, and shift of attention from one case to another. “So it’s very important to challenge the brain with such tasks over time.”

Edwards acknowledges the role of games in stimulating cognitive ability, but is unaware of the evidence from randomized controlled trials that they have an effect on improving cognitive function or reducing the likelihood of dementia and cognitive abilities.

According to Dr. Jessica Langbaum, an Alzheimer’s researcher and director of the Alzheimer’s Prevention Foundation, there is evidence that performing cognitive-stimulating activities, such as solving puzzles, reinforces skills such as thinking, paying attention, and reasoning. he does. What we do not know is whether this effect is a direct result of these activities. It is also not clear to us whether doing such activities delays the onset of cognitive impairments, including dementia or Alzheimer’s dementia.

He believes that the results of this study are remarkable, but it should not be forgotten that the data were provided by the participants themselves and therefore may not be completely reliable.

The effect of table solving on brain balance

According to Dr. Gayatri Devi, a neurologist specializing in memory disorders, the key to a brain in a normal state or decline (including Alzheimer’s decline) is that the function of the human brain is due to a balance between pathology and power. Cognitive is the brain. In other words, when the pathology of the brain is complex (such as a person with severe and progressive dementia), cognitive ability, no matter how high, cannot slow the progression of the disease.

Fortunately, most types of dementia, as well as Alzheimer’s, progress slowly. So we have the opportunity to delay the onset of symptoms or prevent them altogether by boosting brain power and cognitive ability!

Solving the table and other mental activities is one way to strengthen the brain and increase its strength, just as physical exercise does this. As Dr. Dewey puts it, “The bottom line is that over time, as we age, we continue to work on the brain and challenge it.” You do not have to be a fan of table or sudoku; You can learn a new language or start learning a new skill.

“No matter what you do, when your problem is challenging enough, all parts of the brain get involved in finding a solution,” says Dewey. As a result, brain networks and cognitive ability are strengthened.


According to a recent study, people over the age of 50 who are more involved in activities such as table solving and sudoku have better brain function. However, experts point out that because this research was conducted in a correlated rather than random manner, it cannot be said with certainty that mental activity contributes to better brain function.

However, experts believe that challenging the brain with activities such as puzzle solving or other methods such as language learning contributes to mental and cognitive agility. So do not neglect mental activities; Aside from the thrill of solving a puzzle or the joy of learning a new language, these activities help our brains become more refreshed and our minds more agile.
