A Book Review: Knowledge, Ginkgo, Software & Brain Fitness

Varied, novel and challenging: the recipe for good mental exercise!

Does the new book “The Sharpbrains guide to Brain Fitness” meet these criteria?


A common happening in China today:


As the cock crowed, the grandfather left the house on his half mile walk to the little park by the river for his morning Tai Chi with a group of seniors. He was in fact the leader of the group and it fell upon him, a young looking 83 year old to go through the sequence of Tai Chi moves that had been passed down by his grandfather and others before him. His wife sometimes accompanied him but today she had to baby sit the grand-children as their parents were on an early shift. When they finished they sat around for some social chat and drank green tea from their thermal flasks. He walked home refreshed from the morning’s exercise and social gossips. As he neared home he could hear his grand-daughter practicing the piano. What lovely Mozart! He stepped into the house to find his grandson busy at a Nintendo game.

“Why aren’t you practicing your violin? If you just play computer games, your brain will turn into water.”

His grandson shut down the Nintendo, “Grandma, you should try it some time. It will be good for your brain.”

“I am too old for it. My brain is all water anyway, according to grandpa!” She just remembered that she had to take her Ginkgo capsules.

The grandson played some scales on the violin and then the Vivaldi A minor. From memory, as that was how he was trained.

At breakfast, the young children listened to Grandpa reciting ancient classical Chinese poems - a long standing family tradition.

Soon the grand-children left for school.

Grandma now cracked some walnuts while grandpa got ready to go to the market to see what fresh fish he could buy that day. The walnut was to go with their home reared free range chicken. They grew their own vegetables too.

Later that day they would be having a good game of Majong with a retired couple.


These people could well have read “The Sharpbrains guide to Brain Fitness” by Alvaro Fernandez and Dr. Elkhonon Goldberg.

SharpBrains

Much of what they did would help to maintain their brain fitness.

The grandfather’s comment on computer game and grandma’s consumption of Ginkgo were “give-aways” that they had not read the new book after all. Ginkgo biloba with its romantic botanical history is no longer the Dementia buster it promised to be. (Those who know of the village in Japan where there are loads of Ginkgo trees could have told you that. The village has the highest Alzheimer rates in Japan.)


I was reminded of Woody Allen’s film, Radio Days, where the young Allen (who else) was brought before the Rabbi by his mother for his advice because Allen was hooked onto the radio. The Rabbi’s skepticism was perhaps not that dissimilar to ours nowadays about computer games and brain exercises. Indeed the young boy should be concentrating on his upcoming Bar Mitzvah and the Torah memorizing.


When I was training in London in the 70s, I spent some time at Queen Square. Those in the know will recognize it as the place for neurology this side of the Atlantic. It was drilled into us then that sadly we were given a number of brain cells when we were born and it was all downhill from then on or something to that effect. It was well known that neurologists were great diagnosticians but for most neurological conditions, not much could be done. How depressing indeed. Even as recently as four weeks ago, I heard a young doctor told his father that there was nothing he could do with his brain cells. One is given so many at birth and no more can be expected. Lord Brain (1895-1966) would have been so proud.


Yet it was also London that shook the world with new discoveries about the brain, and the study was on the most unlikely group of people: Taxi drivers. Their “KNOWLEDGE” was the basis of our knowledge on brain plasticity today. The “KNOWLEDGE” is a term officially used to describe the test the Taxi Drivers had to take to get the licence to drive Taxis in London. Streets in London have evolved over time and are not on any grid system at all. Early postmortem examinations led some pathologists to note the small size of the Taxi drivers’ frontal lobes. Yet actual weight measurement showed that size was all relative. It was the enlarged hippocampal region that created that impression. Later work using modern scanning techniques confirmed the early impressions.


If two to four years of “KNOWLEDGE” acquisition can change the size of the brain in a grown adult, what else could we do?


The rest, as they say, is history.


I have been a regular visitor to the SharpBrain blog and have enjoyed the musings and scientific material presented on the site. When Mr. Fernandez offered the newly published book: The SharpBrains Guide To Brain Fitness for review, I jumped at the chance.


Yes, London Taxi driver is mentioned in the book, and so I thought that is a good sign.


The book also covers the changes to the brains of musicians and medical students. It tells us that just three months of memory work can have noticeable effect on the brain of medical students, and music memory work has similar impact on musicians. I was pleased to learn that Bilingualism helps too. From infancy, I and my siblings were brought up with speaking two Chinese dialects at home.


Will medical schools that have abandoned traditional teachings please bring back Anatomy-the old way?


Did the 300,000 or so that took up piano this year in China know a thing or two about brain plasticity? Currently 30 million children are reported to be learning the piano in China.


The skeptics would see the primary purpose of “The Sharpbrains guide to Brain Fitness” as the promotion of some computer training software. There is no obvious conflict of interest I could detect and the book is a convenient place to look at various software under one roof so to speak. The interviews are interesting but nearly all interviewees have some vested interest in some software. As a child psychiatrist, I find the ones on ADHD showed great promise but I doubt if we are ever going to see the end of the stimulants’ hold on the condition in the West. It is interesting to note that Stimulants never took off in China, a country with a fifth of the world’s population. Computer games, on the other hand, have really taken off there.


The book is easy to read, and has a clear structure, although I found it difficult to look for specific references. Later I discovered that these are to be found on their website.


Bridge and Sudoku were mentioned in passing, along with other favourites like crosswords. There is no mention of Majong although in the East it is all the rage, nor the memory work required in some religions. Their gods might know a thing or two about the brain.

In conclusion, “The Sharpbrains guide to Brain Fitness” is indeed varied, novel and challenging. You might think you can get most of the information on the Web for free (in fact only 30-40%), but the book does conveniently give you all you need to know (for now and perhaps six more months), all in one place.

Thank you very much. I tried to keep a range of subjects from sea to land, from Shakespeare to Operas and from Child Psychiatry to Old Age.
