Playing brain-train games like Sudoku regularly can have a positive impact on your cognitive skills and activate different parts of your brain. Here’s what exactly happens in your brain:

Brain training boosts the prefrontal cortex

The prefrontal cortex is the front part of the brain and plays a crucial role in various cognitive processes and behaviors. It is known for its involvement in executive functions, which include skills needed to plan, organize, and perform complex tasks. When playing Sudoku, the prefrontal cortex becomes active for several reasons:

Problem-solving 

Sudoku is essentially a puzzle that has to be solved by applying logical rules and strategies. You have to think about which numbers can be placed where and which numbers are already excluded based on the rules of the game. This requires using your problem-solving skills, which are partly managed by the prefrontal cortex.

Decision-making 

While solving a Sudoku puzzle, you have to constantly make decisions about which numbers to fill in based on the information available. These decisions affect the progress of the puzzle, and your prefrontal cortex helps you make these decisions by evaluating possible options and choosing the best one.

Planning

When solving a Sudoku puzzle, it is often useful to have a plan, especially when the puzzle becomes more complex. You need to think about what steps to take to solve the puzzle and what strategies to apply. This process of planning and thinking of strategies also activates the prefrontal cortex.

Sudoku and similar puzzle games challenge the prefrontal cortex because they appeal to executive functions such as problem-solving, decision-making, and planning. By playing these games regularly, you can improve the activity and efficiency of the prefrontal cortex, which can lead to improvements in cognitive skills and general thinking ability.

Brain training boosts your memory 

Our memory is an essential part of our cognitive functions and plays a crucial role in everyday mental tasks. It is your brain’s ability to temporarily hold and manipulate information. Playing Sudoku challenges your memory in several ways:

Temporarily holding information 

To solve a Sudoku puzzle, you need to remember the numbers that have already been placed. This information is essential to avoid re-placing the same numbers in incorrect positions. It requires you to store in your memory which numbers have already been used and where they are in the grid.

Manipulating information 

Besides memorizing numbers, you also need to keep in mind the possibilities for future moves. You need to think about which numbers could potentially be placed in certain positions and which numbers have already been ruled out based on the rules of the game. This manipulation of information in your mind is an important aspect of working memory.

Multi-tasking 

Solving a Sudoku puzzle often requires you to think several steps ahead and consider different parts of the grid at the same time. This means you have to constantly retain and manipulate information as you gather new information and make decisions.

By playing Sudoku regularly, you train yourself to use your memory more effectively. You learn to hold and manipulate information quickly, which applies not only to the game itself but also to other aspects of your daily life. An improved memory can be useful in tasks such as remembering shopping lists, following instructions, and solving complex problems. It can also help improve concentration and cognitive flexibility, which is beneficial for all kinds of mental activities.

Brain training gives a boost to your pattern recognition 

Sudoku, as well as all other similar puzzle games, helps improve your ability to recognize and apply patterns.

Pattern recognition 

Sudoku is based on clear rules and patterns. For example, each row, column, and sub-grid must contain all the numbers from 1 to 9 without repetition. By playing Sudoku regularly, you gradually become familiar with these rules and begin to recognize patterns in the grid. For example, you learn that if a particular number already appears in a row, it cannot appear in the same row at a different position. This ability to notice regularities and repeating patterns in the puzzle stimulates the brain to actively engage in pattern recognition.

Applying logic 

To solve a Sudoku puzzle, you need to use logical reasoning to identify and fill in missing numbers. This means not only recognizing existing patterns but also creating and applying new patterns to solve the puzzle step by step. The ability to apply logical reasoning to complex problems is an important part of cognitive skills, and Sudoku exercises this aspect excellently.

Cognitive flexibility

As you gain more experience with Sudoku, you will find that you can apply different strategies to solve the puzzle. This requires cognitive flexibility, which means being able to change approaches and try new strategies if one doesn’t work. Developing this flexibility can improve your overall problem-solving skills.

Puzzle games are thus excellent exercises for pattern recognition and applying logic. They challenge you to notice regularities and repetitive structures in the puzzle, strengthening your cognitive skills. These skills are not only applicable to solving puzzles but can also be useful in other situations where you need to recognize patterns, apply logical reasoning, and think flexibly.

Brain training is especially important in aging

It is known that the function of the prefrontal cortex generally declines as people age. This can accelerate if they do not engage in specific “brain training” activities. This decline in prefrontal cortex function is part of the normal aging process and can have several causes. 

Natural reduction of neurons

As we age, some neurons in the prefrontal cortex may die off, and this can lead to a loss of connections between neurons. This can reduce the efficiency of the prefrontal cortex.

Changes in neurotransmitters

Aging can lead to changes in the levels of neurotransmitters, the chemical messengers in the brain. This can affect communication between neurons in the prefrontal cortex.

Reduction in plasticity 

Plasticity refers to the brain’s ability to adapt and form new connections. As we age, the brain’s plasticity usually decreases, which can result in a reduced ability to learn and remember new information.

Changes in blood supply and metabolism 

The prefrontal cortex requires good blood supply and optimal metabolism to function properly. Aging can cause changes in blood supply and metabolism, which can affect the prefrontal cortex.

Although the function of the prefrontal cortex may naturally decline as we age, lifestyle choices such as regular exercise, a healthy diet, and mental activities such as brain training games can help maintain and possibly even improve cognitive function. Much research has been done showing that certain forms of cognitive training and mental stimulation can help the prefrontal cortex stay active and slow cognitive decline. Here, results may vary from person to person.

Q&A

Question: How does playing Sudoku benefit cognitive function?

Answer: Playing Sudoku engages the prefrontal cortex, which is responsible for problem-solving, decision-making, and planning. It also enhances memory and pattern recognition, improving overall cognitive skills.

Question: Can Sudoku help improve memory?

Answer: Yes, Sudoku challenges your working memory by requiring you to remember numbers placed in the puzzle. This exercise can lead to improved memory not only in the game but also in daily life tasks.

Question: What cognitive skills does Sudoku enhance?

Answer: Sudoku enhances a range of cognitive skills, including problem-solving, logical reasoning, pattern recognition, and cognitive flexibility. It engages the brain in various ways to improve overall cognitive function.

Question: Is Sudoku effective in preventing age-related cognitive decline?

Answer: While Sudoku and similar brain-training activities can help maintain cognitive function in aging individuals, they may not completely prevent age-related decline. However, they can slow down the process and keep the brain active.

Question: Are there other activities besides Sudoku that can boost cognitive function?

Answer: Yes, activities such as crossword puzzles, chess, physical exercise, and learning new skills or languages can also enhance cognitive function and contribute to brain health. Variety in mental and physical activities is beneficial.

They say that wisdom comes with age. But there’s also a downside: cognitive decline. Many elderly people find themselves struggling more with memory and learning new things. However, this decline can be slowed down and in many cases even halted.

The Active Study is the largest study ever conducted on cognitive skill training and its positive impact. The results were still evident 10 years after the research, even though the test group had only done an exercise 15 to 20 times. It’s like going to the gym a few weeks ago and still reaping the benefits 10 years later.

Brain training helps reduce signs of mental aging.

The Active Study, formally known as ‘Advanced Cognitive Training for Independent and Vital Elderly‘, examined 2,832 individuals aged between 65 and 94 years from six major American cities.

Utilizing a range of brain training techniques, including playful games and game-like elements, they were able to measure differences before and after the exercises. In many instances, there was an immediate and significant improvement in cognitive functions.

Participants were randomly assigned to one of four groups:

• A group that received training in memory strategies.
• A group that received training in reasoning skills.
• A group that received training in the speed of information processing.
• A control group that received no training.

The training sessions, infused with game elements, were structured and consisted of 10 sessions spread over several weeks. As a result, after the training, participants in the first three groups demonstrated improvements in the skills they were trained in, compared to the control group. For example, the group trained in reasoning skills outperformed in tasks that demanded reasoning. In some instances, these enhancements lasted for years after the training.

Daily brain training in a game format.

Today, there are countless ways to train your brain. You can solve a puzzle from the newspaper, learn new words, or play a brain training game. We believe that training should be fun, and that’s why we advocate for the latter.

Given our passion for games and (mental) health, it’s no surprise that we are brain game developers ourselves. After all, if there’s something best done daily, make sure it’s enjoyable and offers varied exercises. A game is the perfect fit for this, as every challenge within a game brings something new.

But it becomes even more enjoyable when you play the game digitally. Take our SudokuX app, for instance. When you compare it to a Sudoku booklet, there are significant differences. In an app, you don’t need to scratch off or erase numbers, you can get hints, receive automatic updates with new boards, and so much more. Additionally, you usually have your smartphone with you, so if your grandson calls while you’re playing, you can simply pause the game and answer.

Importance of Consistency in Brain Exercises:

The findings of the ACTIVE study suggest that our brains are much more flexible and adaptable than previously thought, even in later life. This phenomenon, known as neuroplasticity, has significant implications for elderly care and education.

While the results of the research demonstrate a lasting effect, as with physical exercises, consistency is the key to cognitive training. Playing brain games sporadically does not offer the same benefits as playing regularly.

In addition, variety in activities is important. Brain games with different levels and boards play a crucial role in this regard and the digital era has opened up new possibilities for brain training. Apps like SudokuX, mentioned above, can provide personalized games that adjust their difficulty level to the user’s skills. This kind of dynamic adaptation can make a more effective impact on cognitive abilities because it consistently challenges the brain.

A Healthy Mind, A Healthy Life

Preserving a sharp mind is invaluable for a fulfilling and active life, regardless of age. Cognitive health plays a central role in the ability to enjoy daily activities and stay connected with loved ones.

Regularly playing brain games is an investment in oneself that not only enhances the quality of life but also promotes independence and vitality in later years.

For some seniors, making the transition to a Sudoku app can be daunting, especially if they’re accustomed to solving puzzles from newspapers or puzzle books. Family or other loved ones can play a crucial role in this process. Most brain game apps, like SudokuX, are available for free download, and with a few instructions, even a novice can enjoy playing these types of games.

Conclusion:

The battle against cognitive decline in aging is a challenge, but recent research and technological advancements provide us with powerful tools. Through regular, targeted training, ideally, in a way that is both enjoyable and challenging, we can hope to reduce the signs of mental aging and maintain a higher quality of life as we grow older. Combining scientific insights with the capabilities of modern technology promises an exciting future for anyone aiming to keep their brains healthy and active.

Older adults who stay physically and mentally active have higher levels of brain proteins that improve connections between neurons. These play an important role in our memory. This protective effect applies to everyone. Even in people who showed signs of dementia.

A study published in Neurology in juli 2020, shows that people who participate in multiple healthy mental and physical behaviors reduce their risk for Alzheimer’s disease, the…most common form of dementia, reduce significantly. This study lasted 6 years and five healthy lifestyles were followed. From healthy eating to regular mental exercises. People who followed at least 4 out of five healthy lifestyles were about 60% less likely to develop Alzheimer’s disease.

Below are 16 ways you too can contribute to staying mentally healthy.

1. Be socially active

Maintaining friendships and social contact with people around you has a positive influence on maintaining your cognitive function. Research from 2019 showed that people with more frequent social contact were less likely to experience cognitive decline and dementia.

Some social activities that can help stimulate the brain include:

• Exchanging experiences
• Having discussions
• Play games together

2. Do aerobics

When you think of aerobics, you think of slim twentysomethings in fascinating shape, but you are never too old to do certain types of aerobics. Regular aerobic exercise increases blood flow to your brain and also increases the size of your hippocampus. This is the part of your brain involved in verbal memory and learning. A 2017 study published in The Journals of Gerontology, found a clear link between little exercise and the risk of dementia.

The researchers also did MRI scans of about 2,000 people aged 60 or older and found that the more active they were, the larger their hippocampus was. What was particularly special about the study was that the effects were greatest in people over 75. Definitive proof that it is never too late to exercise regularly.

3. Do strength training

Strength training does not mean that you have to deadlift 7 days a week. There are strength training exercises for every body type that contribute to better physical and therefore mental health. In 2020, a study published in the journal Neuro Image found that six months of strength training can help prevent hippocampal shrinkage in older adults.

A study has also been published in the Archives of Internal Medicine. This study lasted 12 months and was done with women aged 65 to 75 years. This showed that weightlifting has a very positive effect on memory and other cognitive functions. According to the researchers, this is because you are very focused on performing very specific movements. This has a positive effect on the neural circuits in your brain.

4. Practice Tai chi

Tai chi has a positive effect on the ability to reason, plan, problem-solve, and remember in older adults. In 2018, researchers conducted a 12-week study of older adults who practiced Tai chi. This research was published in the journal Frontiers in Aging Neuroscience. 

There was clearly more activity in the prefrontal cortex, the part of the brain where thinking at a higher level takes place. Even adults with mild cognitive impairment due to dementia saw an improvement in their cognitive ability.

One explanation for this is that any form of cardiovascular exercise improves cognition because it improves oxygen supply to the brain. Tai chi also reduces stress, which can help people concentrate better.

5. Play a game of cards

Everyone has played a game of cards and this often simple game appears to lead to a greater brain volume. Researchers discovered that regularly playing a card game has a very positive influence on memory and thinking skills.

Frequently played card games are:

• Solitaire
• Bridge
• Gin rummy
• Poker
• Chasing hearts

6. Learn new words

The English language has approximately 170,000 words, but the average person only knows and uses between 20,000 and 40,000 words. You can benefit from this to stay mentally fit, as different brain areas are active if you actively expand your vocabulary.

A fun way to expand your vocabulary is to look up words online or in a newspaper that you don’t know exactly what they mean. Look up the meaning of the word, write it down on a note, and try to remember the meaning the next day.

7. Use all your senses

When you sit in a restaurant, do you see all the items on the table, notice how the food smells, hear what music is playing, actually taste what you are eating, and feel the feel of your wine glass?

A research report from 2015 shows that consciously using all your senses helps to train your brain.

8. Try new routines

The brain becomes ‘lazy’ if you do the same thing every day and need a challenge to stay fit. Simply adjusting your route to the supermarket and perhaps even the type of transportation you use will give your brain the challenge it needs. Even simple changes such as taking the stairs instead of the elevator every now and then can contribute to a better mental state.

9. Remember ‘everything’ about a conversation partner.

When you talk to someone, try to remember as much about that person as possible. Then it is not only about what someone says but also whether the person wears glasses, what color socks the person is wearing, and how the person looks.

When you try to remember what you remember the next day, you train many parts of your brain. This not only concerns your memory but also your visual and audio skills.

10. Play a game of checkers

Checkers is easier than chess for most people. Research from 2015 shows that these types of cognitively stimulating games have a very positive influence on your brain volume and general cognitive health. It even appears that it has a positive influence on the brain in people who have an increased risk of Alzheimer’s.

11. Do your shopping without taking a list with you

Everyone goes shopping, but try making a list of at least 20 items and then leave the list at home. This basic way of training your memory helps you remember lists of words better and stimulates your overall mental fitness.

12. Start making music

You don’t have to become Mozart or Pavarotti to combat brain aging by making music. Singing or playing a musical instrument places great demands on your brain, keeping it flexible. Consider, for example, the prefrontal cortex, which is associated with higher-level cognitive functions, including planning, decision-making, and emotional expression.  

13. Do mental arithmetic more often

Everyone can do it, but because of digital tools, we do it less and less. Mental arithmetic, according to research published in Advances in Experimental Medicine and Biology in 2021, has an enormously positive effect on people’s mental health. Mental arithmetic mainly stimulates the parietal lobe of the brain, which plays an important role in processing numbers, performing mathematical calculations, and understanding spatial relationships. It also involves retrieving facts and thereby training your memory.

14. Learn a foreign language

In a meta-analysis published in October 2020 in Psychonomic Bulletin & Review, learning a foreign language was associated with a lower risk of dementia.

It did not matter which language was learned and how long it took to master the language.

15. Draw a map of an area

If you visit a new location, try to draw a map of the area afterward. Researchers examined London taxi drivers who were required to memorize the city map. Compared to people who had other professions, their Hippocampus was many times larger. The research conducted by scientists Eleanor Maguire and Katherine Woollett at University College London found that these drivers were better at navigation and had better spatial memory.

16. Play puzzles

All puzzles contribute to reducing the risk of age-related cognitive decline and even the risk of neurodegenerative diseases such as Alzheimer’s disease. A game like Sudoku also contributes to cognitive skills, such as logical thinking, problem-solving, reasoning, memory, and attention. Practicing these skills regularly keeps the mind active and alert.

Conclusion:

As we journey through life, the importance of maintaining cognitive health becomes increasingly evident. The steps we take today to keep our brains fit can have a profound impact on our future well-being. By embracing these 16 simple ways to improve cognitive health, we not only sharpen our minds but also enhance our quality of life. So, let’s take that extra game of cards, learn a new word, or even dance to your favorite tune. With each small effort, we empower ourselves to age gracefully, keeping our minds as vibrant as ever.
