Poor sportsmanship

I try to avoid revisiting a subject I have pontificated on in the recent past, but when I encounter a situation in which scientists are behaving unscientifically it is hard to remain silent. In 2002, a Pittsburgh neuropathologist named Bennet Omalu performed an autopsy on Mike Webster, a former National Football League (NFL) lineman who had died in his 50s. Webster had been exhibiting bizarre behaviors and was developing dementia. What Dr. Omalu found in Webster’s brain was a collection of changes that have become known as chronic traumatic encephalopathy (CTE).

In the decade following the publication of Dr. Omalu’s findings in the journal Neurosurgery in 2005, there has been some unsavory back and forths between the NFL’s Mild Traumatic Brain Injury Committee and Dr. Omalu that I learned about in the Wall Street Journal (“The Doctor the NFL Tried to Silence,” by Jeanne Marie Laskas, Nov 24, 2015). The doctor’s side of the story has been published in a book, “Concussion” (New York: Penguin Random House, 2015). “Concussion,” the movie based on the book, was slated for release in December.

The tangle of he said – our experts don’t agree has involved the University of Michigan and Boston University, and the smell of conflict of interest hangs over the NFL’s choice of experts and its decisions to publish or not publish the results of various studies. It now appears that Dr. Omalu’s discovery was the tip of an iceberg of undetermined size. As happens far too often, assumptions and attributions have been made in haste based on scanty evidence from small studies that have surely failed to control for all of the possible contributors.

Considering the results of the autopsies on a few NFL players, it is probably reasonable to suspect that there is something in the culture surrounding professional football that makes some of the players vulnerable to central nervous system damage. And blows to the head are likely to be one of those factors. However, leaping to the conclusion that parents shouldn’t allow their young children to play football is another story. But that is just what Dr. Omalu has done in an op-ed piece that has appeared in the New York Times (“Don’t Let Kids Play Football,” Dec 7, 2015).

Relying heavily on the analogy with cumulative effects of cigarette smoking, Dr. Omalu continues to fan the flame that he ignited with his initial autopsy finding. The timing of the piece is interesting in light of the movie’s release date of Dec. 25. While his discovery of CTE in a professional player is important, Dr. Omalu’s case for prohibiting children from playing football is rife with half-truths and unwarranted conclusions.

For example, he states that in his 30 years as a neuropathologist he has yet to see a “neuron that naturally creates a new neuron to regenerate itself.” True, but he fails to report that there is new evidence that the long-held dictum that neurons can’t heal themselves may be wrong.

Dr. Omalu observes that “if a child who plays football is subjected to advanced radiological and neurocognitive studies during the season and several months after there can be evidence of brain damage at the cellular level even if there were no documented concussions or reported symptoms.” It took some time, but I eventually found the study to which I assume he is referring, by Dr. Christopher T. Whitlow of Wake Forest University, Winston-Salem, N.C., presented at the Radiological Society of North America meeting in December of 2014. Its lead author is careful to state that conclusions should not be drawn from this small preliminary study and observes, “it is unclear whether or not these effects will be associated with any long-term consequences.” However, Dr. Omalu asserts that “If that child continues to play over many seasons, these cellular injuries accumulate to cause irreversible brain damage.” He states this as fact without any supporting evidence.

Fortunately, the American Academy of Pediatrics has presented a more balanced perspective on allowing children to participate in football in light of what we are learning about the health of professional players (“Tackling in Youth Football” [Pediatrics. 2015;136(5)e1419-31]). Dr. William P. Meehan III and Dr. Gregory L. Landry, speaking for the Council on Sports Medicine and Fitness, point out that serious head and neck injury in young football players is very unlikely, and that by teaching proper tackling technique, these injuries can be further decreased.

The real solution to the problem that Dr. Omalu first brought to light in 2002 lies with zero tolerance for the practice of tackling headfirst at all levels of football. Although the NFL has made some feeble attempts to discipline its teams, there is still more that should be done. Every professional and college football game is being video recorded, often from multiple angles. Retrospective analysis of these images should be used to discipline players whose injury-threatening tactics have not been detected by the officials during the game. Multiple game suspensions meted out promptly, and without possibility of appeal, would go a long way to return football to being the safer sport it was when leather helmets discouraged players from using their heads as lethal weapons.

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.”
