Letters from Maine

Nature or nurture in primary care?


 

Does the name Bruce Lipton sound familiar to you? Until a few years ago the only bell that it rang with me was that I had a high school classmate named Bruce Lipton. I recall that his father owned the local grocery store and he was one of the most prolific pranksters in a class with a long history of prank playing. If the name dredges up any associations for you it may because you have heard of a PhD biologist who has written and lectured extensively on epigenetics. You may have even read his most widely published book, “The Biology of Belief.” It turns out the Epigenetics Guy and my high school prankster classmate are one and the same.

Dr. William G. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years.

Dr. William G. Wilkoff

After decades of separation – he is in California and I’m here in Maine – we have reconnected via Zoom mini reunions that our class has organized to combat the isolation that has descended on us with the pandemic. While I haven’t read his books, I have watched and listened to some of his podcasts and lectures. The devilish twinkle in his eye in the 1950s and 1960s has provided the scaffolding on which he has built a charismatic and persuasive presentation style.

Bruce was no dummy in school but his early career as a cell biologist doing research in stem-cell function was a surprise to all of us. But then high school reunions are often full of surprises and should serve as good reminders of the danger of profiling and pigeon-holing adolescents.

Professor Lipton’s take on epigenetics boils down to the notion that our genome should merely be considered a blueprint and not the final determinant of who we are and what illnesses befall us. His research and observations suggest to him that there are an uncountable number extragenomic factors, including environmental conditions and our belief systems, that can influence how that blueprint is read and the resulting expression of the genes we have inherited.

At face value, Bruce’s basic premise falls very close to some of the conclusions I have toyed with in an attempt to explain what I have observed doing primary care pediatrics. For example, I have trouble blaming the meteoric rise of the ADHD phenomenon on a genetic mutation. I suspect there are likely to be extragenomic forces coming into play, such as sleep deprivation and changing child-rearing practices. In my Oct. 9, 2020, Letters from Maine column I referred to a Swedish twins study that suggested children from a family with a strong history of depression were more likely to develop depression when raised in an adopted family that experienced domestic turmoil. His philosophy also fits with my sense that I have more control over my own health outcomes than many other people.

However, Professor Lipton and I part company (just philosophically that is) when he slips into hyperbole and applies what he terms as the New Biology too broadly. He may be correct that the revolutionary changes which came in the wake of Watson and Crick’s double helix discovery have resulted in a view of pathophysiology that is overly focused on what we are learning about our genome. On the other hand it is refreshing to hear someone with his charismatic and persuasive skills question the status quo.

If you haven’t listened to what he has to say I urge you to browse the Internet and sample some of his talks. I am sure you will find what he has to say stimulating. I doubt you will buy his whole package but I suspect you may find some bits you can agree with.

It still boils down to the old nature versus nurture argument. He’s all in for nurture. I’m still more comfortable straddling the fence.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.
