• Brain Teasers = Brain Training by Dr Jack Lewis

    Dr Jack Lewis is keen to get people motivated to get the best out of their brains, so has compiled a quick overview of brain training options:

    Brain teasers are good for you. Brain teasers include word games, number puzzles, spot the difference, Where’s Wally-type games, attention directing or splitting challenges, general knowledges quizes and so on. Brain training simply involves perfoming various different brain teasers on a regular basis. Your brain constantly adapts to serve you better. The more often you perform a certain mental function the more the brain will do to make changes so that the next time you do it, you can perform it slightly faster, with a greater degree of success and more efficiently.

    How do we know that practice increases the connections between different brain areas? Two brain imaging studies have demonstrated that when people practice a skill very hard for prolongued periods of time despite the fact that the changes happen at the ultramicroscopic level of the synapses where two brain cells meet the net effect of billions of these changes occuring over many months is that the grey matter gets larger in the part of the brain responsible for that function. The part of the brain that controls hand movements is significantly larger in professional string and keyboard musicians than non-musicians because of all the training they have done over the years to manipulate their instruments with split second precision. Another brain region, the hippocampus, creates and recalls memories particularly for geographical locations and is significantly larger in the brains of London Cabbies – who navigate around their city based on a sound KNOWLEDGE of every landmark, road and bridge – than in the brains of bus drivers – who simply drive the same route over and over again.

    The synapses connecting various different groups of brain cells together that are responsible for perfoming a certain task, say a crossword for instance, are strengthened each time to try to solve the puzzle in order that they can function slightly more efficiently next time round. If you do the crossword every day, then the net effect of many slight overnight adjustments to the brain areas involved in searching your memory for suitable words that have a certain meaning, a certain number of letters and specific letters in at certain positions within the word, become noticably better after just a few days. The same goes for number puzzles. Or games that involve prolonged concentration. Or the ability to recall trivia when it becomes relevant to conversation.

    We all know that practice makes perfect and the strengthening of connections between the relevant brain areas to enable more efficient communication between them is the reason why. Of course getting good at doing crosswords is not particularly useful in its own right, but the point is that once you become good at recalling suitable words for the sake of the crossword, you will also find it easier and quicker to bring the appropriate word to mind during conversation or when creating written documents – and that can be extremely useful.

    There are numerous websites that have compiled a large variety of different puzzles (http://www.brainbashers.com/puzzles.asp) and various others where you can try out electronic versions of classic physical puzzles like the Tower of Hanoi (http://www.mazeworks.com/hanoi/index.htm). However these all pale into comparison next to custom-designed brain training games such as those available at Lumosity (www.lumosity.com), which have not only the advantage of a much more aesthetically-pleasing look and feel of games that are genuinely fun and engaging to play, but also as you have to log in to play (they offer a free 30 day trial) you can keep track of how your performances improve over time.

    Nintendo DS were the first console manufacturer to produce and market games with the aim of improving brain function which all started with the release of Dr Kawashima’s Brain Training in 2005. This predominantly involes some quite predictable tasks like the Sudoku number puzzles, simple rapid-fire arithmetic, but also some unexpected treats like the Stroop Test (naming the colour of the font ignoring the meaning of the word which can be tricky when the word RED is written in blue font!) which take advantage of some pretty nifty voice processing software. I must admit I found myself thinking “can I really speak to this machine?”

    The effect of the advertising campaign that accompanied the release of this game was quite profound as it not only encouraged everyday consumers to purchase Nintendo’s products, but more importantly sent out the message that the brain is something that you can do something pro-active to improve; a concept that has been long-accepted to be the case in children but the mantra “you can’t teach an old dog new tricks” meant that this was rarely considered to be applicable in adults. Such a message is particularly enticing for people entering into old age, for whom the prospect of holding onto their marbles for as long as possible is extremely desirable and thus motivating. In this regard the key thing to remember is that, as far as the brain is concerned, it’s a simple matter of use it or lose it. Exercising brain areas involved in problem-solving by tackling word games, logical reasoning problems, memory challenges and number puzzles keeps such mental faculties in tip-top condition. If you don’t continue to use these mental abilities then they will fall into disrepair because the brain receives no indication that connections between appropriate areas should be maintained and reinforced. The upshot: it is never too late to improve your mental fitness. By emulating the lifestyles of individuals enjoying a healthy brain in their 80s and 90s, who have regular social interaction, cards games, read extensively, stay physically active and challenge themselves daily with various puzzles and quizes, the odds of being afflicted by Alzheimer’s disease are reduced by 25%.
