This post was trigged by a coincidence; I got a mail from Venkat about this blog while I was reading ‘The Wisdom Paradox’ by Elkhonon Goldberg; the coincidence is that the blog and book are on a similar theme – Dementia or the atrophy of the brain. It is a known fact that our brain atrophies as we age and eventually most of us will lose some and an unfortunate few will lose most of our cognitive abilities. This topic is of great interest to me since I have recently crossed the milestone 4 decades of existence and every now and then I worry about the possibility of me spending the last years of my existence wearing a bib and trying to recollect what I did a minute ago!The book; The Wisdom Paradox is a paradox in the sense that it gives you hope and at the same time it reconfirms your fears about aging too. The bad news first -after the initial stages of development and maturity (till your thirties) our brain starts to degenerate, starting with the newly evolved neocortex that make us who we are, humans (neocortex controls the working memory, speech and language) and the right hemisphere deteriorates more than the left. So you will have issues with new learning, analytical ability and creativity. Your ability to learn new languages will be affected too (there goes my goal of learning French this year).
The good news is that what you lose in creativity and novelty you gain in wisdom. Wisdom is an acquired response to recognized patterns. So during the early stages of our life we assimilate new information and develop neural patterns. As we age, the brain begins to atrophy, losing about 2% of its size per decade, but we reach insightful conclusions intuitively based on the lifelong collection of the neural patterns. This, you see, is the strength of leadership. The experience accrued over a lifetime being used in decision making, esp in abstract situations – like running a nation or an organization.
The point to reflect is that this wisdom can’t dawn overnight when we become old, we need to collect various experiences in our early stages of life and build the neural patterns that would help in achieving this wisdom, even when as we lose our analytical and learning abilities. So, spend your early years hunting for knowledge (like reading this blog :)) that can be turned into wisdom later.
The Blog; I believe that the overall, degeneration (cells dying as we age) would be of little consequence – so it does not matter that, ‘You had more brain cells the day you were born than you’ll ever have again’. You definitely had less brains when you were born than you’ll ever have. Also, it is very complex, elephants have double the neurons as humans, and if you are talking about the brain to body ratio, then birds have a better ratio… I am sure you will agree that we have better cognitive capabilities compared to elephants and birds (of course, can’t say that for everyone I work with). So, it is difficult to say why you will lose your mind -whenever that happens; but you can be sure that it is just not because of reduced cells. It is worthwhile to note that research has not established the reason or medication for, say, Alzheimer more than 100 years since Dr. Alzheimer described it first. So I find this article to be assuming too many things and making it simplistic. It is possible that dementia is more of genetic in nature and probably has no cure or prevention. And your cognitive skills at the ninth decade would probably be thanks to the strong genes provided by your parents (and generations before them).
I agree that the brain needs constant stimulation (not the one provided by TV) that allows the neurons to form new connections. We should constantly try to learn new skills, improve your social interactions and broaden our knowledge (browsing the net does not count) and ponder about them (hence, having a mid-life crisis is probably a good thing for your brain).
Yes, every time I search for that wretched remote or the car keys; I am worried that very soon I may forget my own name, I am still not sure how to avoid it completely – let me try Sudoku or Rubik’s Cube or learn to draw and paint.
