Have you already read The Sharp­Brains Guide to Brain Fit­ness?

Let’s see…

1. Pick the only part of your body that does not con­tain fat:

a. Arm
b. Thigh
c. Brain
d. None

Answer: d) Fats are also present in the brain: in neu­rons’ mem­branes to keep them flex­i­ble. These fats are the omega 3 and omega 6 fatty acids mol­e­cules. (Page 32 of the book)

2. Pick the only food prod­uct that doesn’t con­tain Omega-3 fatty acids

a. Tuna
b. Wal­nut
c. Kiwi
d. Jelly Beans

Answer: d) Fatty acids can be found in cold-water fish (such as mack­erel, her­ring, salmon, and tuna), kiwi, and wal­nuts. (Page 33)

3. Pick the only food prod­uct that doesn’t con­tain antioxidants

a. Olive oil
b. Milk
c. Nuts
d. Berries

Answer: b) Antiox­i­dants can be found in veg­etable oils, nuts, green leafy veg­eta­bles (e.g., spinach), cit­rus fruit, and berries. (Page 33)

4. Chronic Stress cannot:

a. Pre­vent you from being cre­ative
b. Kill brain cells
c. Pre­vent you from sleep­ing
d. Kill liver cells

Answer: d) Pro­longed expo­sure to adrenal steroid hor­mones like cor­ti­sol, which is released into the blood stream when we are stressed, can lead to cell death and block the for­ma­tion of new neu­rons. (Page 35)

5. What type of phys­i­cal exer­cise is the best for your brain health?

a. Weight lift­ing
b. Aer­o­bic exer­cises
c. Flex­i­bil­ity exer­cises Read the rest of this entry »

Think about this: How can any­one take care of his or her brain when every week brings a new bar­rage of arti­cles and stud­ies which seem to con­tra­dict each other?

Do sup­ple­ments improve mem­ory? Do you need both phys­i­cal and men­tal exer­cise or is one of them enough? Which brain train­ing approach, if any, is worth one’s time and money?

We tried to address these ques­tions, and many oth­ers, in our recent book, The Sharp­Brains Guide to Brain Fit­ness (182 pages, $24.95), that we pre­sented at Games for Health Con­fer­ence last week. The book is the result of over two years of exten­sive research includ­ing more than a hun­dred inter­views with sci­en­tists, pro­fes­sion­als and con­sumers, and a deep review of the sci­en­tific lit­er­a­ture, led by neu­ropsy­chol­o­gist Elkhonon Gold­berg and myself with the help of cog­ni­tive sci­en­tist Pas­cale Mich­e­lon. As we wrote in the Intro­duc­tion, what we wanted to do first of all was to debunks these 10 myths on brain health and brain training:

Myth 1. Genes deter­mine the fate of our brains.
Facts: Life­long neu­ro­plas­tic­ity allows our lifestyles and actions to play a mean­ing­ful role in how our brains phys­i­cally evolve, espe­cially given longer life expectancy.

Myth 2. Aging means auto­matic decline.
Facts: There is noth­ing inher­ently fixed in the pre­cise tra­jec­tory of how brain func­tions evolve as we age.

Myth 3. Med­ica­tion is the main hope for cog­ni­tive enhance­ment.
Facts: Non-invasive inter­ven­tions can have com­pa­ra­ble and more durable effects, side effect-free.

Myth 4. We will soon have a Magic Pill or Gen­eral Solu­tion to solve all our cog­ni­tive chal­lenges.
Facts: A multi-pronged approach is rec­om­mended, cen­tered around nutri­tion, stress man­age­ment, and both phys­i­cal and men­tal exercise.

Myth 5. There is only one “Use It or Lose it”.
Facts: The brain is com­posed of a num­ber of spe­cial­ized units. Our life and pro­duc­tiv­ity depend on a vari­ety of brain func­tions, not just one.

Myth 6. All brain activ­i­ties or exer­cises are equal.
Facts: Var­ied and tar­geted exer­cises are the nec­es­sary ingre­di­ents in brain train­ing so that a wide range of brain func­tions can be stimulated.

Myth 7. There is only one way to train your brain.
Facts: Brain func­tions can be impacted in a num­ber of ways: through med­i­ta­tion, cog­ni­tive ther­apy, cog­ni­tive training.

Myth 8. We all have some­thing called “Brain Age”.
Facts: Brain age is a fic­tion. No two indi­vid­u­als have the same brain or expres­sion of brain functions.

Myth 9. That “brain age”‚ can be reversed by 10, 20, 30 years.
Facts: Brain train­ing can improve spe­cific brain func­tions, but, with research avail­able today, can­not be said to roll back one “brain age”‚ by a num­ber of years.

Myth 10. All human brains need the same brain train­ing.
Facts: As in phys­i­cal fit­ness, users must ask them­selves: What func­tions do I need to improve on? In what time­frame? What is my budget?

Do you have other myths in mind you would like  us to address?

We have started to receive great feed­back from the health­care com­mu­nity, such as this email from a neu­ro­sur­geon in Texas:

“I really like the book, it is com­pre­hen­sive with­out being too tech­ni­cal. I have rec­om­mended it to sev­eral patients. There are some other books that I expected would be greeted with enthu­si­asm, but were too com­plex for most of my patients. I think this book is right in the sweet spot”.

A short, sweet, enter­tain­ing read of a com­plex topic, with timely (writ­ten in 1/09) reviews of 21 top tech­nol­ogy prod­ucts, as well as informed and expert pre­dic­tions of where this bur­geon­ing brain-fitness field is headed. More impor­tantly, after you read it, you’ll have a good, detailed sense of where you, per­son­ally, can act to improve your own couch-potato brain — and how to keep it fit and flex­i­ble your whole life. The Sharp­Brains Guide To Brain Fit­ness reminds of us all why books (and not just googling a topic) can be well worth your time and money. Two Stetho­scopes Up — check it out. life.”

The book:  The Sharp­Brains Guide to Brain Fit­ness (avail­able via Amazon.com Here, review copies avail­able upon request).

Descrip­tion: While most of us have heard the phrase “use it or lose it,” very few under­stand what it means, or how to prop­erly ‚“use it”‚¬ in order to main­tain brain func­tion and fit­ness. The Sharp­Brains Guide to Brain Fit­ness is an invalu­able guide that helps read­ers nav­i­gate grow­ing brain research and iden­tify the lifestyle fac­tors and prod­ucts that con­tribute to brain health and fit­ness. By gath­er­ing insights from eigh­teen of the world’s top sci­en­tists and offer­ing tools and detailed descrip­tions of over twenty prod­ucts, this book is an essen­tial guide to the field of brain fit­ness, neu­ro­plas­tic­ity and cog­ni­tive health. An acces­si­ble and thought-provoking read, The Sharp­Brains Guide to Brain Fit­ness edu­cates life­long learn­ers and pro­fes­sion­als in health­care, edu­ca­tion, busi­ness, etc., on emerg­ing trends and fore­casts of what the future will hold.

The grow­ing field of cog­ni­tive train­ing (one of the tools for brain fit­ness) can appear very con­fus­ing as the media keeps report­ing con­tra­dic­tory claims. These claims are often based on press releases, with­out a deeper eval­u­a­tion of the sci­en­tific evidence.

Let’s take a cou­ple of recent exam­ples, in suc­ces­sive days:

“It doesn’t work!” type of head­line:
Reuters (Feb. 10, 2009)  For­mal brain exer­cise won’t help healthy seniors: research“
Healthy older peo­ple shouldn’t bother spend­ing money on com­puter games and web­sites promis­ing to ward off men­tal decline, the author of a review of sci­en­tific evi­dence for the ben­e­fits of these “brain exer­cise” pro­grams says.

It works! type of head­line:
Sci­enceDaily (Feb. 11, 2009)  “Com­puter Exer­cises Improve Mem­ory And Atten­tion, Study Sug­gests“
Accord­ing to the researchers, par­tic­i­pants who used the Brain Fit­ness Pro­gram also scored as well as those ten years younger, on aver­age, on mem­ory and atten­tion tests for which they did not train.

So, does struc­tured brain exer­cise / cog­ni­tive train­ing work or not?

The prob­lem may in fact reside in ask­ing this very ques­tion in the first place, as Alvaro pointed out a while ago in his arti­cle Alzheimer’s Dis­ease: too seri­ous to play with head­lines.

We need a more nuanced set of questions.

Why? Because:
1. Cog­ni­tion is made of sev­eral dif­fer­ent abil­i­ties (work­ing mem­ory, atten­tion, exec­u­tive func­tions such as decision-making, etc)
2. Avail­able train­ing pro­grams do not all train the same abil­i­ties
3. Users of train­ing pro­grams do not all have the same needs or goals
4. We need to dif­fer­en­ti­ate between enhanc­ing cog­ni­tive func­tions and delay­ing the onset of cog­ni­tive deficits such as Alzheimer’s.
