An Important Book for All to Read

And that book is Nurturing the Older Brain and Mind by Pamela M. Greenwood and Raja Parasuraman of George Mason University.  The book is an extensive review of the literature on the older brain and mind in general, and on Alzheimer’s and dementia, in particular.  Although younger people might think this book is only for us BabyBoomers that would be WRONG WRONG WRONG!  First of all, the magnitude of the problem must be considered.  As people age the probability of suffering  Alzheimer’s increases and with aging populations it will soon reach epidemic proportions.  Hopes for drug cures or preventative vaccines are slim (see the healthy memory blog posts, “The Myth of Alzheimer’s” and “Sigmund Freud and Alzheimer’s Disease”).   Moreover actions you take now can reduce the likelihood of suffering from Alzheimer’s or dementia.  If you have parents, there are things they can do to reduce the likelihood of suffering from Alzheimer’s or dementia.  And if you have children, there are things that both you and your children can do to reduce the likelihood of Alzheimer’s and dementia.  These “activities” or “things” are described in Nurturing the Older Brain and Mind.

Greenwood and Parasuraman note that although the brain might age, cognitive aging is neither universal nor inevitable.  Most individuals do not show a decline in cognitive functioning in old age, even though the probability of suffering such a cognitive decline increases as we age.  Moreover it has been noted in many healthymemory blog posts that there are many individuals who do not suffer cognitive decline in spite of the tell-tale amyloid plaque and neurofibril tangles of Alzheimer’s.  The only explanation of this fact has been that these people have developed a cognitive reserve.  Greenwood and Parasuraman present a neurocognitive framework to describe how this might be done.

Nurtuiing the Older Brain and Mind is a  scholarly work of the highest order reviewing an extensive research literature on the topic including both human and non-human species.  Nevertheless, I believe that it is written on a level where it should be accessible to the general reader.  Even if it takes a bit of a reach for the general reader, it is a reach well worth taking.  Although the healthymemory blog will draw heavily on this work, there is no way I can even hope of doing it justice.

The only criticism I have of this work is that it does not address mindfulness, although I do understand why it was not addressed.  Part of the reason can be found in the immediately preceding blog post on random controlled trials or random clinical trials (RCTs).  The researchers do not regard the research on mindfulness as being significantly “rigorous.”  I remember when I was a graduate student there was a debate on whether we humans can control our autonomic nervous systems with out minds (heart rate, for example).  Now there were people in the east who were highly trained meditators who were able to do this.  Nevertheless, most psychologists would not accept this conclusion unless they could train someone to do it in a psychological laboratory.  They regarded these meditators as using some sort of “trick.”  Well the same thing has been said of mnemonic techniques, but these mnemonic techniques not only enhance memory, but also reveal important insights into how memory works.  Similarly mindfulness research will provide practical insights into how we can control our minds and our bodies.  These skills will be central not only to preserving cognitive functioning, but also to enhancing cognitive functioning.   I predict that mindfulness will play an increasingly strong role in nurturing the older brain and mind.
