Ten Brain and Brain Health Myths

These myths are copied directly from the SharpBrains website because these are common myths that need to be corrected.  This is an extremely good website with much information on brain and brain health sharpbrains.com

Top 10 brain and brain health myths, debunked:

Myth 1. Genes deter­mine the fate of our brains.
Fact: Life­long brain plas­tic­ity means that our lifestyles and behaviors play a significant role in how our brains (and therefore our minds) evolve physically and functionally as we get older.

Myth 2. We are what we eat.
Fact: We are what we do, think, and feel, much more than what we eat. (Even if, yes, nutrition plays a role)

Myth 3. Med­ica­tion is the main hope for brain health and enhance­ment.
Fact: Non-invasive inter­ven­tions such as aerobic exercise and meditation can have com­pa­ra­ble and more durable benefits, and free of side effects.

Myth 4. There’s nothing we can do to beat Alzheimer’s disease and cognitive decline.
Fact: While nothing has been proven to prevent the pathology of Alzheimer’s disease, there is abundant research showing we can delay the onset of symptoms for years.

Myth 5. There is only one “it” in “Use it or Lose it”.
Fact: The brain presents many neural circuits supporting a variety of important cognitive, emotional, and executive functions. Not just one. (Which is one of the reasons we should stop thinking about magic pills and silver bullets)

Myth 6. Intervention XYZ can help reverse your brain age 10, 20, or 30 years.
Fact: The concept of “brain age” is a fic­tion. Some brain functions tend to improve, and some to decline, as we get older. Nothing can be said to “reverse brain age” in a general sense.

Myth 7. There is a scientific consensus that brain training doesn’t work.
Fact: A group of scientists did issue such a statement, which was promptly contradicted by a larger group of scientists. Consensus…that is certainly not. Brain training, when it meets certain conditions, has been shown to transfer into real-world outcomes.

Myth 8. Brain training is primarily about videogames.
Fact: Evidence-based brain training includes some forms of med­i­ta­tion, cog­ni­tive ther­apy, cog­ni­tive training, and bio/neurofeedback. Interactive media such as videogames can make those interventions more engaging and scalable, but it is important to distinguish the means from the end, as obviously not all videogames are the same.

Myth 9. Heart health equals brain health.
Fact: While heart health contributes significantly to brain health, and vice versa, the heart and the brain are separate organs, with their respective functions and relevant interventions. What we need is to pay much more systematic attention to brain health, so it can advance as much as cardiovascular health already has.

Myth 10. As long as my brain is working fine, why should I even pay attention to it?
Fact: For the same reasons you add gas to your car, and change the oil regularly– so that it works well, and for a long period of time.

The only response Healthymemory would quibble with concerns Myth 4.
Myth 4. There’s nothing we can do to beat Alzheimer’s disease and cognitive decline.
Fact: While nothing has been proven to prevent the pathology of Alzheimer’s disease, there is abundant research showing we can delay the onset of symptoms for years.
Although it is true that nothing has been proven that the pathology of Alzheimer’s Disease can be prevented, proof is a very high standard.  And it would be very difficult if not impossible to present an iron clad proof.  Nevertheless, Alzheimer’s is by no means inevitable and there have been many people whose brains were wracked with the amyloid plaque and neurofibril tangles that constitute the definitive diagnosis who never exhibited any of the cognitive or behavioral symptoms.  It is said that these people had built up a cognitive reserve.  So the advice of the healthy memory blog is to strive to build this cognitive reserve.  Moreover, it is quite possible that although the physical indicators of Alzheimer’s cannot be prevented, the neuroplasticity off the brain might preclude any cognitive or behavioral symptoms.  It is these symptoms that are of primarily importance.  Neuroplasticity is likely the result of maintaining a healthy and active mind along with physical health and mindfulness.

There is also a myth that there are drugs that slow Alzheimer’s.  This myth was debunked by Thomas E. Finucane, a professor of Medicine at Johns Hopkins University School of Medicine in a note in the April 30, 2016 Washington Post titled “Drugs don’t (yet) slow Alzheimer’s.”  To quote from this note, “The Food and Drug Administration required package insert for cholinesterase inhibitors comes to a different conclusion: “There is no evidence that donepezil (Aricept) alters the course of the underlying dementing process.”

The National Institutes of Health conference on Minimal Cognitive Impairment came to the same conclusion.

Belief that drugs can slow the progression of dementia is carefully cultivated by Big Pharma, but scientists do not believe that currently available drugs have any effect on the underlying brain disease.”

If you read the healthy memory blog post “The Myth of Alzheimer’s” you will find that Peter J. Whitehouse, M.D., Ph.D. does not believe that either a medical cure or a medical vaccination will be developed.  Dr. Whitehouse worked for many years  to find such a drug.  Moreover, research in this field is quite lucrative.  Nevertheless, Dr. Whitehouse believes that this is a dead end.  His currently research involves working with people who have Alzheimers’s.  Given neuroplasticity and some remarkable treatments for some severely debilitating conditions.  See the healthy memory blog post, “The Latest Discoveries in Neuroplasticity.”  For more details see the books by Dr. Norman Doidge, “The Brain’s Way of Healing:  Remarkable Discoveries and Recoveries from the Frontiers of Neuroplasticity.  This is the sequel to his earlier book, The Brain That Changes Itself.  In the view of Healthymemory, this approach is more likely to yield results that looking for the silver bullet.  Of course, the best means of maintaining a healthy memory  is to have a growth mindset and meditation.
