Cutting Down Concussions (And Junk Science)
There has been a lot of discussion around CTE and how it may impact the future of football and other contact sports - some gadflys predict it will be football's ultimate demise or render the sport unrecognizable - but the studies are not yet sufficiently comprehensive to draw many conclusions beyond a general agreement that concussion is a euphemism for brain injury and that limiting repetitive brain injury is a good thing unless you think Leon Spinks was a latter-day Oscar Wilde.
I wrote this a year ago, and I think it still holds up - particularly my prediction that various self-anointed safety lobbies will be misusing and abusing the scientific method enough to give Karl Popper the post-mortal shits and Charles Darwin the dirt nap red-ass when discussing this issue.
One of the major problems with the current informal "studies" is that the research has primarily been on athletes who exhibited aberrant behavior before their deaths. Just as with steroids in the 1980s, it's now assumed by media and fans that any athlete standing naked in the road firing his Glock at traffic helicopters, who then turns it upon himself, is suffering from CTE as a direct result of their participation in a violent sport. And confirmed when the post-mortem reveals brain trauma.
Unfortunately, they forget to mention that almost all of us have brain scarring and lesions - from sports, from falling from a high chair when you were 3, from head butting your bros in Lake Havasu.
It's the scientific equivalent of shooting an arrow at a target, drawing a circle around it, and yelling bullseye.
For starters, we need brains from healthy former athletes who don't exhibit aberrance to provide control groups. Lots of them. Peer review might also be nice. And a half dozen other little niceties that make up meaningful inquiry.
As that process unfolds and we get epidemiologist's and neuroscientist's involved in framing the discussion rather than pop science, the question, then, is how best to minimize brain injury without turning the game into two-hand touch?
I don't share the assumption of safety as an absolute and inarguable priority that trumps all other considerations - part of the value of a contact sport is precisely the idea that you're in some form of peril. That written, if technology and some sensible rules can prevent brain injury, it's a very good thing.
Which brings us to Virginia Tech. They may not be saving football so much as reframing the argument. Va Tech just released the first comprehensive study on helmet safety and how helmet choice may provide as much as 30% reduction in concussion rates.
Now all that has changed. Researchers at Virginia Tech have produced the first brand-by-brand, model-by-model ranking for the likely concussion resistance of helmets. A star-rating system modeled on crash safety rankings for automobiles, the rankings clearly identify the best and worst helmets.
And consider this little snippet:
Now the chilling part: the VSR4 -- Virginia Tech's second-lowest-rated helmet -- was the most common helmet in the NFL last season. The VSR4 is widely worn in college and high school, too. Immediately after the Virginia Tech findings were released, Riddell advised football teams to stop using the VSR4, long the company's best seller.
and this:
Watch the sidelines of NFL and NCAA games -- players are popping off helmets as easily as if they were baseball caps. Many football players don't know that a snug helmet reduces concussion risk, and coaches and equipment managers don't seem to be telling them.
The solution to much of this may not be all that dramatic after all. It may simply require a little technology, a little education, some real studies, and the dissemination of good practices.
Not so good for headlines, but good for players and fans.

What ? I find nothing in this article to direct anger towards. This thread is not as exciting as the discussion on nuclear armageddon.

I know. I had terrible timing for this one.
How about this: the Longhorn Network prevents concussions.

hate to disagree with you, but there is a control group of normal brains. In average brains (including those who fell off high chairs and head butted their frat bros), CTE affects something like 5 in 1000. Yet CTE “dark spots” have been found in 95% of former NFL brains.
Bill Simmons interviewed Chris Nowinski march 8th, and it was some pretty interesting stuff. Give it a listen next time you’re sitting in traffic.

And advised them to buy new helmets?
In other news, my barber just advised me that I should get my hair cut much more often… staring immediately. He didn’t have any particular helmet recommendation, though.

My understanding is that you pretty much have to be dead to be diagnosed with CTE. Therefore, it’s pretty difficult to find a healthy former athlete who’s also dead to use as a control group.

echo base -
The brains they have are almost exclusively of NFL players who exhibited irregular behaviors and Nowinski’s sample sizes are miniscule. It’s called selection bias. It is not a broad cross section of athlete brains. In short, we need Roger Staubach and Drew Brees’ brain just as much we need Andre Waters and Dave Duerson.
And if CTE is present in more or less all NFL brains, then we need to understand why a minority exhibits pathology while so many do not. Predisposing genetic factors etc. That doesn’t even consider college and high school populations.
The relevance of the 5 in 1000 for the general population is that even this small occurrence means a huge raw number of people in a population of 300 million. If that pathology was so cleanly linked to aberrant behavior, I suspect CTE-head would be a part of our lexicon as much as crackhead or tweaker.
The idea that CTE = explanation for all crazy ex NFLer incidents (as it’s currently being used in the media) has no scientific basis.
In short, you can’t wave around a numerator without a denominator.

Correct. CTE can only be revealed by post-mortem brain examination.
Uh, we’re all going to die roach. It’s simply a matter of getting “healthy” ex-players to volunteer to give up their brains for study. I’m positive epidemiologists have already started soliciting them.

Replace the “Hawaii Fullback” with me and the “porous drywall” with steel and it basically looked like this.
Full disclosure: I have had three concussions.

Don’t they have to dye the brain cells to see CTE? Not sure how that could happen while you’re alive, unless a squid f*cks you in the earhole.
Eh, I’ll Google it.

The answer is a big fat maybe. The NYT has an article from Dec 2010 about using magnetic resonance spectroscopy to possibly identify CTE in the living. MRS is like an MRI but it returns chemical composition rather than a physical image. The scientists in the article go to great pains to explain that the evidence they have is too statistically small to say anything, but that initial scans of five athletes with CTE symptoms all showed the same abnormal chemical markers. Google didn’t really bring up a lot about it otherwise.

Another interesting tidbit from the article: if CTE is in fact widespread amongst NFL players and they come up with a way to diagnose it in the living, the NFL could be screwed. Any NFL player who’s played a game in California is covered by its very generous workers comp laws. You can do the math from there.

Right now CTE can only be definitively diagnosed to a publish-in-journal scientific standard by direct tissue examination.

I think the problem is that all the armor that players wear is just too good. Before we had hard plastic shoulder pads and helmets players couldn’t spear each other. Now its a pretty stupid thing to do, but you can still put your head on a ball and walk away.

Wouldn’t you need non-athletes to use as the control group?
My whole problem with the way CTE is covered is that there’s a popular belief just concussions and sudden violent impacts which cause it – the NFL exploits this by fining James Harrison etc and pretending like it’s doing something about the problem.
The C in CTE is for “chronic” – the current thinking (whether or not it’s junk science) is that it’s a result of the cumulative effects of numerous impacts rather than a big hit or two (not that a big hit isn’t damaging as well).

Bob – there may be some truth to your humor. A minority of people may be predisposed to develop CTE based on an abnormal cellular response to repeated neuron or blood vessel microtrauma – kind of like inflammation run amok over time where the inflammatory response, and not the inciting trauma itself, is the main contributor to the progression of CTE. In the brain, secondary cell death is a term used to describe the toxic overactivation of neuronal glutamate receptors after head trauma, seizures, or ischemic events. In theory, if you mitigate or stop the overactivation of glutamate receptors and associated pathways to eventual cell death, you could preserve a lot more otherwise healthy brain following an insult.
It could be that current headgear is adequate for most while no type of headgear will adequately prevent symptomatic CTE in those predisposed.

Another question relates to brain ‘reserve’. To what extent is everyone experiencing microtrauma in football with the same or similar process that can lead to CTE, and to what extent do some have ‘more to lose’ before any symptoms might appear?
It could be that someone like Scipio, for example, could lose a lot of brain from chronic head trauma without CTE manifesting while the same amount of loss in another would be symptomatic. Or perhaps in a less dramatic way, while Scipio may not appear outright encephalopathic, his persona might become indistinguishable from nordberg.

Clearly, we’re all going to die, I’m merely pointing out that since the healthy players will likely live much longer than the ones with CTE, it’s going to take a while before they have a decent sample size of players that played at the same time, with the same equipment etc.

As he said, the point isn’t that it has been conclusively proven that football is so dangerous that it should immediately be banned it everywhere. It’s that clearly further study is needed. Controls, peer review, epidemiologists and neurologists all, to be sure. But while the government approved and semi-taxpayer funded cartel of asshole billionaires that already has the most absurdly favorable labor rules one could ever imagine for an athletic league spends its time drooling and rubbing its hands together at the thought of wresting away another billion dollars from its employees, it might also decide to actually acknowledge the potential scope of the problem and devote some resources toward investigating it and mitigating it. And the moronocracy that is sports journalism might also try to put some pressure on the billionaire assholes to take some responsibility for the consequences of their business. Instead, we all spend on time on meaningless sideshows like tut-tutting James Harrison for saying nasty things about blessed Roger Goddell, and whether or not Bart Scott is right that doing away with two-a-days would during the NFL into a collection of weak pussies. Malcolm Gladwell, while a sensationalist, is really not the enemy here.
