Earlier this month I gave a talk in an achingly cool studio space in Wapping; a short distance east along the Thames from Tower Bridge. This future-proofing healthcare event seemed to be a great success and I even got meet a hero of mine. I’m happy to report that not only is Henry Marsh a well-regarded neurosurgeon and fantastic author (whose book Do No Harm I reviewed here back in 2015), but he is also a brilliant speaker!

My brief was to open the event with a quick overview of what the brain is, how its building blocks are arranged to accomplish all the marvelous things our brains can do and then offer a handful of tips and tricks that everyone can use to get their brains firing on all cylinders. When I give these talks there is always hard science behind whatever I share with the audience. It occurred to me that flashing up the relevant references on screen is probably not sufficient if people wanted to go back to the original science papers at a later date. In this month’s blog I thought I’d provide a few links to research articles summarising some of the research that motivates me to recommend three brain hacks to help people keep their grey and white matter in tip-top condition.

SLEEP

Many people consider it a nuisance to spend 1/3 of life unconscious. In our increasingly busy lives, spare time tends to get squeezed mercilessly and the time we spend sound asleep in bed usually suffers as a result. This is a travesty because it is when we are asleep that the brain does all its running repairs and maintenance work. It is when temporary memories reverberating around the brains neural highways are re-visited, the superfluous ones deleted and more important ones consolidated into long term memory by the laying down of proteins. According to a brilliant study published in the journal Science the metabolic waste materials that build up in the brain over the course of the day are also removed at a much faster rate when we are asleep compared to when we are awake.

If these metabolic waste materials are allowed to accumulate in brain tissue it can have a negative impact on brain function and can potentially build up to levels that are neurotoxic, hence prolonged sleep deprivation being deadly for all animals. So a huge part of the reason it’s vitally important that we all try to get at least 7 and ideally 8 hours of sleep each night is to give the brain an opportunity to banish as much of these potentially toxic materials from the brain as possible. While the 2013 study was in mice, a paper published this month in the Proceedings of the National Academy of Science also demonstrated that sleep deprivation has a similar impact on the clearance of toxic substances from the human brain too.

I’ll not go into further detail here as next month’s blog will be a review of Matt Walker’s book Why We Sleep, but I’ll conclude with one more sleep-related tip. It is perfectly normal to feel drowsy in the mid-afternoon. Acting on the urge to have a 15-20 min nap is not just restorative, enabling you to continue your daily activities with greater efficiency but, perhaps even more importantly, it also vastly improves memory retention and creative problem solving. Personally, I take a nap most days. In fact, I’m feeling the urge right now, so I’ll complete this blog once I’ve taken 40 winks (1 nap-wink = 30s ;-)…

… that’s better! (I genuinely did). Not only do I practice what I preach but I regularly urge businesses to encourage their staff to take an afternoon nap every single time I speak at a business conference. On many levels it is flagrant false economy to allow the myth  that napping is tantamount to laziness to be perpetuated. It simply couldn’t be further from the truth.

HYDRATION

Every single morning we wake up dehydrated. That’s because we have to keep breathing 24/7 to stay alive. This is the only way we can keep our oxygen levels topped up (to maximise the release of energy from glucose to keep our vital biological processes ticking over) and to eliminate the carbon dioxide that is a key waste material of this process, which would otherwise increase the acidity of the blood with potentially catastrophic consequences. To keep these gases moving in and out of the bloodstream, the inner surface of the lungs must be kept moist, which means that every time you exhale you are blowing away a little bit of water vapour.

Assuming we stay asleep for 7-8 hours, we will always wake up a little bit dehydrated, which knocks all sorts of biological mechanisms out of kilter. From the brain’s perspective the most important impact of this dehydration is that it has a negative impact on neural transmission – the capacity for each of your 86 billion neurons to efficiently send electrical messages along their wire-like axons and thereby influence other brain cells. People usually wake up a little bit grumpy because the first thing to go awry when people are dehydrated is mood. The cognitive impairment associated with dehydration also explains why you’re likely to find yourself prone to getting mixed up in the process of executing straightforward tasks. Accidentally putting coffee in the saucepan with the porridge instead of the cafetiere where it belongs is a personal favourite, as is the struggle to find everything needed for the day ahead in the daily rush to get out the door on time.

Do yourself a favour: make drinking a glass of water (laying in wait on your bedside table) the first thing you do after switching off the alarm to help you minimise the amount of time you spend lacking a sense of humour and unable to perform the simplest of tasks effectively each morning due to a dehydrated brain. Having started the day well, monitor your mood and when you feel irritable, before you try and blame others for being so annoying, think to yourself – when was the last time I drank water? (NB not coffee, fizzy drinks or juice, but just plain, old-fashioned, H₂O).

COFFEE

There is pretty good evidence to suggest that people who drink a moderate amount of coffee each day have a lower risk of Alzheimer’s disease and also (in men at least) Parkinson’s disease. We still don’t know what exactly it is about the magic bean that confers these neuroprotective effects – the most popular hypothesis is that the benefits arise as a result of all the antioxidants contained in the coffee bean helping to soak up all the free radicals that would otherwise interfere with our DNA.

Despite these benefits, there are drawbacks to a voracious appetite for coffee. One broadly overlooked peril of the coffee habit is that caffeine has a very long half-life. It takes 6 whole hours to reduce the concentration of caffeine in the bloodstream by half (NB this takes much longer if you’re pregnant or on the contraceptive pill, but less time if you’re a smoker). This means that if you have the equivalent of 4 cups of coffee’s worth of caffeine in your bloodstream at midday, then it will take until 6pm before this has been reduced to 2 cups-worth and 6 hours after that – at midnight – this will finally have been halved again: down to 1 cup of coffee’s-worth of caffeine. Clearly anyone who is in the habit of drinking coffee throughout the afternoon is going to have so much stimulant swimming around their system come night time that it will inevitably interfere with their sleep. We’ve already covered the reason’s why this is bad news for brain health.

The upshot is this: to avail yourself of the neuroprotective benefits of coffee, without suffering negative impacts on sleep in terms of onset, duration and/or quality, then get all your coffee drinking out of the way in the morning and if you absolutely must take caffeine onboard in the afternoon, then at the very least try to switch to green tea instead (15% of the caffeine in a cup of coffee). The next time a waiter or waitress offers you an after-dinner coffee, feel free to inform them that they are effectively tempting all their customers to play roulette with the health of their brain.

NEXT UP

I’m giving another talk at the end of this month – at 1pm on Sat 28^th April – at the Leeds International Festival on the topic of how technology impacts our brains. If this is of interest, then tickets are available here – it’s free!

In addition to these monthly brain blogs, I regularly tweet about brain-related research that hits the lay press (@drjacklewis), I do a fortnightly podcast about the more unusual scientific breakthroughs (Geek Chic’s Weird Science) and in July 2018 my new book Science of Sin will hit the shelves in the UK (11th Sept in the USA).

As we move around in the world we develop a sense of how to get from A to B. This relies heavily on the hippocampus, a brain structure nestled deep within each of the temporal lobes, responsible for many functions vital to cognition such as memory and navigation. This is the brain structure famed for becoming physically larger as a result of all the practice driving around London that the drivers of London’s famous Black Cabs have to accrue before they can pass “The Knowledge.” Whilst their memory for the 25,000 roads and 20,000 major landmarks that enable them to instantly reel off the route they’d take to get from one place to another is extraordinary, for the 33% of those born in 2015 will live long enough to develop dementia at some point in their lives this situation is reversed. Difficulties with navigation, even familiar routes between places visited many times before, is one of the problems in daily life that can herald the approach of full-blown dementia. Understanding the normal trajectory of changes in navigational ability over the lifetime of a health brain is a vital first step. With or without dementia our abilities to memories complex routes becomes slowly but surely compromised by the normal processes of age-related cognitive decline. We need to know what is normal for each age group before we could be in a position to use a steeper than normal decline in navigational ability as an early warning signal, ideally before any memory deficits have had a chance to rear their ugly heads. As our understanding of the metabolic processes that lead to various forms of dementia improve, this early warning could prove to be a vital mechanism in triggering prophylactic treatments early enough to slow down disease progression.

Hugo Spiers, a memory researcher and neuroscientist at University College London, launched a smartphone game in 2016 called Sea Hero Quest, which aims to do just this. Over 2.5 million people have played this surprisingly fun, engaging and challenging game so far, generating the equivalent of an astonishing 9,400 years worth of lab data. The game involves memorising a map of waterways around which a series of numbered buoys have been distributed. Once you’ve planned the journey you’re going to make and tucked it away in your working memory, the map is then taken  away and your job is then to steer your little fishing boat (increasingly customisable as you progress through the game) by tapping the left or right side of the touch screen. The terrain varies from idyllic sandy paradises to rainy, foggy, bumpy rides across perpetually undulating swell. Thanks to the funding from Deutsche Telekom and Glitchers – the tech-gurus who actually created the game – the graphics are beautifully rendered, the gameplay is smooth and unlike most games designed to answer important scientific questions, every aspect of the user experience is highly polished. As was the delivery of the first results announced at SfN 2016 and summarised below by the man himself…

 

 

Personally I was surprised by how hard some of the levels were. I play a lot of brain training games (e.g. PEAK Review, BRAIN AGE 2 Review ), just to keep myself up to date on the latest offerings, and am now accustomed to finding myself able to get maximal scores on most categories of games pretty quickly through daily play. Not Sea Hero Quest. Once I got past the easier earlier levels, I often found myself getting lost in the mist, or going round and round in circles having forgotten how to get from buoy 3 to buoy 4. As a consequence, not only did I help scientists like Hugo Spiers and colleagues from the University of East Anglia and Alzheimers Research UK to generate data (anonymously, you only have to give your age) but I also got an insight into what the future might have in store for me should I become one of the unfortunate 1 in 3 that get clobbered by dementia in my post-retirement years. As you progress from level to level you periodically get to chase down one of a large variety of sea monsters. Having dodged innumerable obstacles along the way the monster in question eventually leaps out of the water at you and your task, is to resist the temptation to hit the button on your camera to take a photo of the rare and exotic sea beast in question, until the very last second when the captured image is at its most aesthetically pleasing.

Overall, I found playing this game great fun, very challenging at times and doubly satisfying knowing that it would, in some small but meaningful way, help science to get some much needed answers about how the human brain keeps track of where it is and where it’s going in health, so we can better understand when this system breaks down in disease.

I would just like to take a moment to applaud @HugoSpiers and collaborators for finding a way to genuinely enable people to #gameforgood. Hats off to you all… your Cannes Lion was thoroughly well deserved!

In addition to these monthly blogs you can get daily brain tweets about other amazing developments in the world of neuroscience by following me on Twitter (@DrJackLewis). And for a fortnightly appraisal of the latest quirkly stories from the wonderful world of science on general there’s always the totally free Geek Chic Weird Science podcast available from iTunes, Podbay, Libsyn and many others.

It’s that time of year again!

Every day I trawl the internet for fascinating, illuminating pearls of brain wisdom to leak out of neuroscience laboratories across the planet.

So each year I look back on a year’s worth of brain tweets to see what’s been trending recently.

This year the topic I appear to have been tweeting about the most, with over 50 separate articles shared on this topic via the social networking site Twitter, is brain technology.

In second spot are the tweets drawing attention to the science podcast I’ve been doing with RadioX’s Lliana Bird for the past 18 months. Incidentally we’re currently turning this into a book. We’re literally writing it right now. She’s sat right opposite me as I type. We’re 50,000 words down and have just 30,000 to go. It’ll be in all good book shops and online repositories in time for Christmas 2016. We’re tremendously excited.

In third place with just over 40 citations is the topic Youth Brains – which is what I label any cool science that is of relevance to baby brains, infant brains, teenage brains and brain development in general.

Anyway, I could go on – but a glance at the following histogram should tell you everything you need to know about the topics contained in this digest of my tweets from Feb 2015 to Jan 2016. Enjoy…

What Does Caffeine Do To Your Brain?

 As a neuroscientist who spends much of his working life giving brain talks at events all around the country (at schools, conferences and science festivals) I’ve noticed that one theme catches public imagination over and over again: How does caffeine work? What does it do to my brain? How long does it stay in my system? Is it really that bad for me? This is one reason why it became one of the key topics in the “Smart” Drugs chapter of my book: Sort Your Brain Out. In this blog I’ll cover some of the most regularly asked questions.

 

How long caffeine takes to leave your system?

It depends what other drugs you’re on. If you’re on the contraceptive pill it can take up to twice as long for your liver to remove caffeine from your system. So people “on the pill” can find themselves particularly sensitive to its effects because consecutive doses stack up and are not cleared out as swiftly as in everyone else. But if you’re a smoker it is the other way around. Caffeine is removed from your system at double the speed of a non-smoker.
If you’re neither a smoker nor on the contraceptive pill the concentration of caffeine in your bloodstream is halved every 5-6 hours, but it really does depend on the individual as this “half-life” varies greatly from person-to-person.

 

Is it beneficial to have caffeine before a meeting / presentation / to improve concentration?

Caffeine blocks the receptors of an inhibitory neurotransmitter called adenosine, which under normal circumstances reduces overall activity across the brain. By blocking these receptors and removing the dampening influence on brain activity, caffeine increases activity across brain pathways involved in alertness, focusing attention and initiating body movements. This why people dosed up on caffeine can get quite jittery.
Whether or not caffeine is beneficial for you in a meeting / presentation or to improve concentration whilst working depends on how much you’ve already had. There’s a sweet spot where you will feel more alert and switched on at moderate levels, but beyond that you can become so wound up that it has effects that are deleterious to performance (see description of caffeinism below).
However the increase in feelings of alertness and ability to focus attention only gets regular coffee drinkers up to levels enjoyed by non-caffeine drinkers everyday. This is because once you’re a caffeine addict the brain tends to increase the numbers of adenosine receptors to compensate for the fact that there’s loads of caffeine swimming around in your brain on a daily basis. This means that your average coffee drinker has more inhibitory receptors in their brain dampening activity levels to a greater degree – so they will feel more sluggish whenever they don’t have caffeine in their system.

 

Is caffeine good or bad for you in the long run?

There seem to be some long-term benefits to drinking caffeine even if the short-term benefits don’t amount to a whole hill of (coffee) beans. It has been observed that regular drinkers of moderate amounts of caffeine (3 cups / day) have a lower incidence of Parkinson’s, Alzheimer’s, liver and heart diseases. This may be due to the increased numbers of inhibitory receptors triggered by ever-present levels of caffeine dampening activity levels in body and brain. The decreased activity levels across the brain caused by the larger numbers of inhibitory receptors in the caffeine drinkers’ brains may relieve the pressure on dopamine neurons that are compromised in Parkinson’s disease and the acetyl choline neurons that get clogged up with various proteins in Alzheimer’s disease. In other words caffeine seems to slow down the process of cell death so that symptoms of these diseases kick in several years later than in your average non-caffeine drinker. At the moment this mechanism is purely speculative. The jury’s still out on the precise mechanism that might account for these observations, but the evidence supporting the concept of moderate amounts of caffeine having a neuroprotective influence on the brain is steadily increasing.

 

 

Is it important to control and monitor your caffeine intake?

A dose of 10g is deadly – 100 cups and a human may well find themselves popping their clogs as a typical cup of brewed coffee contains 100mg of caffeine. (NB you may notice that in the above video from the lovely people at ASAPscience they say 1 cup of coffee has 150mg – presumably they brew it stronger over in Canada 🙂 For the non-coffee drinkers out there here are some average caffeine contents of some other popular drinks. There are 80mg in a can of Red Bull, 75mg in a cup of instant coffee, 50mg in a cup of tea, 30mg in a can of Coca Cola.

Very high but not deadly doses can lead to a quite severe psychiatric condition known as caffeinism: “which is characterised by restlessness, agitation, excitement, rambling thought and speech, and insomnia.” (Winston et al, 2005). It is important to control and monitor caffeine intake because too much can interfere with appetite, make people anxious or depressed, not to mention the fact that anything that interferes with sleep will have a deleterious effect on the brain. Everyone’s sensitivity to caffeine is slightly different, but if you have trouble sleeping then you’d be well advised to avoid caffeine at least 5-6 hours before bedtime – for your brain’s sake.

3 cups of coffee per day is considered a “moderate dose” for most people. Get these in early enough to avoid any potential for them to interfere with sleep and you should get the apparent long-term brain benefits without the negative consequences associated with excessive consumption (DISCLAIMER: this should not be interpreted as medical advice – it is just the science-based opinion of the author who has a Ph.D. in neurobiology i.e. not a medical degree!).

 

I don’t like tea or coffee, are there any other sources of caffeine?

Caffeine is also found in kola nut (one of the original ingredients of coca cola) and guarana – a wonder berry from the Brazilian rainforest; it’s also found in low quantities in chocolate. Caffeine is also included as a stimulant in many cold and flu remedies – so beware what you reach for when you wake up in the middle of the night with a bunged up nose!

By the way: if you study the picture on the left very carefully you’ll find a face amongst the coffee beans – can you find it?

Keep looking… he’s definitely there and you’ll kick yourself for doubting me when you find him!!

As we progress through life we  inevitably find ourselves becoming increasingly forgetful. It is not as if bouts of forgetfulness never occurred when we were younger. It’s just that it begins to happen more and more frequently – to the point where it becomes much more noticeable; even troublesome . From our mid-twenties onwards we lose more neurons (brain wires) and synapses (connections between the brain wires) than we build. The long term end point of this perfectly natural, gradual process of brain aging is dementia. By which I mean if we all lived to the impossibly grand old age of 200, every single one of us would have developed dementia of one description or another along the way. In reality very few of us will even make it to the grand old age of 100, let alone 200. Of those that do, not everyone will have become plunged into the amnesic fog of dementia. So what is the difference between individuals that do and don’t develop dementia well into their senior years? Is it blind luck? Or is there something we can do to lengthen our dementia-free status?

Contrast the lifestyles of people in their seventies who do and do not suffer from Alzheimer’s disease and clues about how to keep your brain ticking over nicely, well into old age, jump right out at you. Those who do not suffer with this dreaded disease tend to have been more committed to a regular exercise regime throughout their later years; hitting it as hard as their inevitable physical infirmities would allow (TOP TIP: Tai Chi is an excellent example of a low impact physical exercise which improves strength and flexibility at any age. It requires no equipment and can be practiced wherever you happen to be). They tend to have been more engaged in a wider array of social activities. They tend to have been careful with their diet in the long term, favouring a healthy Meditteranean-style diet (see below for more) over a typical modern Western diet (often high in saturated fats and sugars). They also tend to have been more proactively involved with their local community and more  motivated to seek regular mental stimulation. People are now being advised to adopt a variety of brain-healthy habits if they wish to reduce the likelihood of developing cognitive deficits that the progression of Alzheimer’s disease can, but does not always, induce.

Alzheimer’s disease is the most common of the many different types of dementia, affecting 10% of those over 65 and almost 50% of people over the age of 85 (Evans et al, 1989). Dementia describes a syndrome that involves progressive cognitive decline occurring at an accelerated pace compared to the very gradual loss of mental faculties associated with normal aging. Dementia can involve the deterioration of reasoning, judgement, thinking, mood control, language, understanding and, most famously of all, memory. Colloquially-speaking, Alzheimer’s disease is an almighty metabolic cock-up: a brain protein (beta-amyloid) is not constructed properly due to a misprint in the genetic recipe, causing it to form tiny sticky clumps (plaques) that develop between brain cells, preventing them from communicating with each other properly and eventually killing them off entirely. To make matters worse neurofibrillary tangles accumulate within brain cells, which also ultimately leads to cell death.

Depending upon which brain structures these plaques form in, different mental functions can be disturbed. For instance, a brain structure that typically gets more than its fair share of amyloid plaques and neurofibrillary tangles in Alzheimer’s is the hippocampus. As I’ve described in a previous brainpost this brain structure is critical for the formation of memories and so when its function is compromised by the plaques and tangles of Alzheimer’s, people can become extremely forgetful.

To date, scientific research has yet to come up with a treatment to stop the formation of these amyloid plaques and neurofibrillary tangles, but there is evidence that drug treatments designed to boost the cholinergic neurotransmitter system can make symptoms less severe. Furthermore and extensive body of studies has gradually accumulated over the past 20 years to indicate that some people are able to tolerate the disruption caused by these plaques better than others (e.g. Katzman et al, 1988). The Katzman study described individuals who had shown no cognitive impairment whatsoever in life, yet post-mortem examination of their brains revealed that telltale signs of Alzheimer’s disease (the plaques and tangles) which had progressed to a considerable degree. This disparity begs the question: if two people’s brains are affected by the same degree of plaque damage, why does one continue to enjoy normal mental faculties, whilst the other suffers severe impairments to their memory, thinking and mood? The concept of “cognitive reserve” was introduced to describe brains which seemed to be able to compensate for the damage done by Alzheimer’s, presumably by using other brain networks not affected by the metabolic damage to take over certain cognitive tasks.

A separate study, this time involving 593 individuals in New York over the age of 60 and on an “at risk of dementia” register, concluded that “increased educational and occupational attainment may reduce the risk” of developing Alzheimer’s disease. A more recent study conducted in the UK concluded that cognitive reserve is almost entirely mediated by childhood cognitive ability and educational attainment, whilst whether people had successful careers or not had very little influence. So does this mean that the only way to “plaque-proof” yourself is to study hard at school and stay in education for as long as possible? Well, yes and no. Yes – in the sense that this certainly seems to protect you from the ravages of amyloid plaque buildup. No – because there ARE things you can do to build up your cognitive reserve in later life, they just have nothing to do with what you do for a living and how good you are at it.

DIET

Diet may well influence the rate at which Alzheimer’s disease progresses, probably due to the negative influence of a modern Western diet on the brain’s blood vessels. In a recent article, prominent Alzheimer’s researcher Dr Scarmeas describes a study providing evidence that a traditional Meditteranean diet – characterised by lots of fish, unsaturated fats, vegetables, fruit and cereals – seems to protect against the development of Alzheimer’s disease. In a different study which used a mouse model of the disease it was suggested that coffee may help to slow the progress of Alzheimer’s disease by preventing build up of amyloid plaques.

LANGUAGES

A recent NYT article describes research into bilingual people who seem to develop the symptoms of Alzheimer’s on average 5 or 6 years later than those who speak only one language. This suggests that the cognitive demands of regularly switching between two or more languages may delay the onset of Alzheimer’s. Although this has yet to be proven, it is thought that speaking two languages may increase cognitive reserve by improving the function of prefrontal brain areas involved in executive control. Executive control involves mental functions like holding relevant information in working memory whilst ignoring irrelevant distractions, as well as other faculties relating to problem solving, planning and decision making.

FUTURE TREATMENTS

In the not-so-distant future it may be possible to replace brain cells damaged by the abberent metabolic processes of Alzheimer’s with fresh ones created from a person’s own skin cells. Other recent research has suggested that the amyloid plaques might cause memory problems by attaching to certain important neurotransmitters, and that drugs preventing this from happening may help to ease the symptoms of memory loss associated with Alzheimer’s disease. In light of the importance of early intervention to catch the disease before it causes too much damage new scanning techniques have already been developed to spot the disease before it induces any clinical deficits.

A variety of lifestyle changes can build up cognitive reserve, helping to keep dementia at bay and improving quality of life to boot!

In addition to these fortnightly brainposts you can also get DrJack’s daily #braintweet by following him on twitter.

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%.
