Another Rant and Another Essay, and the Cunning Fennec Fox

 And a good day to you all, Patient Reader . . .



        The weeks past had some interesting developments:






1)     There are just some things in life for which some people, Buddhist or not, can ever forgive another.  I keep saying, and believing, that none of us is only the worst thing we have ever done, or have been accused of doing.  How sad for those hypocrites who spout their liberal understandings; their compassion over suffering and desire; yet get wind of something, true or untrue, never bother to sort out the facts, never desire for themselves an explanation, and just run pell-mell through the world exacerbating situations.  Joke ‘em if they can’t take a fuck.



2)     I was honored, in a bittersweet sort of way, by a classmate who tried to “play matchmaker” (her words) with yours truly and some mystery woman.



“She’s smart and beautiful . . .” (and you know too well, Patient Reader, that I feel beauty is not important . . .  to me, all smart women are beautiful) this classmate tells me.  “I told her all about you and she was all, ‘Oh my God’.”



“I’m really not in a position to try a new relationship,” I tell this girl . . .  we’ll call her Shmauren.  “I am just too busy with school to try anything new.”  The bittersweet?  Bitter was that it was not for one of Shmauren's contemporaries.  That I am no longer considered (nor have I been for quite some time now, I reluctantly admit) desirable by the "Young and Beautiful People."  It was to be for her mom, this set-up.  
 Sweet?  That it was to be for her mom.  Contradictory?  Nope.  What an honor for a guy who is found so appealing that someone would try to set them up on a date with his or her mother.  I mean, flattering, right?  The compliment . . .  The trust!  And-



3)     The PAC NW can get brutally cold.  It’s only the end of November and we’ve dropped into the low 20’s, fa chrissakes.  How will it be when winter officially gets here?  When January gets here?  When Hell finally fucking freezes over?



  
     So really, that’s all the ranting I have to do for now, Kind and Oh-So-Patient Readers.  Just pretty ticked at the unforgiving nature of stupid fucking people.  Even a cynic, jaded and crusty as I, can understand second chances.



            But just for your Sweet Patience, my lovely share-ees, I have another completed paper for you all to peruse at your leisure.  As always, your comments, neg or pos, are welcome.  Bring them on, as they say.



            Without further adieu, I would like to introduce you to “Football Kills.”



            Shall we begin?  Splendid!




Football Kills
By

The Ever-Forgivable Cunning Fennec Fox



            Or, more accurately perhaps: Chronic Traumatic Encephalopathy kills. 

Chronic Traumatic Encephalopathy, or CTE, presents clinically with memory disturbances, changes in behavior and personality, and problems with speech and gait.  Dysarthria, dysphagia, and oculomotor changes are also seen.

Parkinsonian symptoms present in all known cases.  These include rest(ing) tremors, bradykinesia, and exaggerated startle reflex.   Sub-clinical changes include intrinsic plasticity, wherein there are changes in the electrical properties within the individual neurons themselves.  

The areas of the brain that govern memory and speech are primarily in the temporal lobes.  Behavior and personality control centers are found in the pre-frontal cortex.  Gross motor movement is governed by the motor strips found in the parietal lobes in both hemispheres of the brain, whereas fine motor skills and gait are controlled by the cerebellum.  The aforementioned dysarthria, dysphagia, and oculomotor changes are indicators of cranial nerve root or brainstem damage.

As is evident by the laundry-list of symptoms, whatever is happening to CTE patients is affecting the global brain, meaning both hemispheres are involved.

CTE is caused when a brain, over time, accumulates abnormal tau. Tau is a protein necessary in the formation and maintenance of neurons.  Abnormal tau is a major component in neurofibrillary tangles.  Essentially, excessive tau causes neurons to snarl like old fishing line or Christmas lights.

The CTE brain accumulates tau because neurons damaged via repeated trauma demand this neuronal gorilla-glue in greater amounts than those within the healthy brain.  But the damage is too extensive, and the protein throws up its hands in exasperation.  When the damage still goes unrepaired, more tau shows up, and the cycle continues.
       When accumulated thusly, tau damages the very neurons they are designed to repair and make whole.  They choke off nutrients and actually cause macroscopic regions of brain tissue to die off.  The damage to a CTE-afflicted brain can be seen with the unaided eye. 
Similar encephalic changes are seen in prize-fighters; a condition known as dementia pugilistica.  But those are boxers, are they not?

I am writing about Professional Football Players.  These guys are not only as tough as boxers, but they wear protective gear.  Gear that boxers would fight over, were they not so busy fighting over purses and belts.  Football players wear all manner of pads.  They tape up their ankles and wrists to limit lateral, oblique, and anterior/posterior joint slippage; they wear knee braces and back braces and they have cages called facemasks riveted to their helmets.  And let’s not forget they wear helmets in the first place.  How does a brain get injured when it’s wrapped inside a skull that’s wrapped inside a helmet?

Well, the brain is a fragile organ.  First of all, the formidable skull’s thickness can be measured in millimeters.  That’s thousandths of a meter.  Skull bone is tough, but relatively thin.

Beneath the cranium are the meninges, the three layers of tissue that surround the brain and spinal cord in a protective sheath, each layer with its own job to do.  The second and third layers of meninges are separated by cerebrospinal fluid, a sort of liquid shock absorber that doubles as a nutrient bath.  Blood vessels responsible for internal respiration are also located here, within the subarachnoid space.  Directly beneath the third layer, is the surface of the neo-cortex, the outermost layer of the brain proper.

Helmets are designed to cushion a lot of the force of the blow.  But they can’t stop it all.  A professional lineman can sustain a thousand blows to the head each season he plays, with the blows reaching forces up to 20 g’s.  That is the equivalent of driving a car 35 miles per hour into a wall, one thousand times a year.  No helmet made is that good. 
  Consider also that when the skull stops from its movement through space, the inertia of the brain itself is overcome, and it begins its own release of kinetic energy, and moves in the direction of least resistance (that is, until it meets resistance) then sloshes back into place. The brain gets injured whether it meets a bullet, a windshield, or the inside of the cranium.

CTE was first identified and described in 2002, when Dr. Bennet Omalu, a trained neuropathologist, autopsied a professional football player by the name of Mike Weber.  Weber played for the Pittsburgh Steelers from 1974 to 1990.  He was fifty years old when he ended up on Omalu’s slab.

Upon gross examination of the cadaver, Omalu was surprised that Weber was only fifty years old, as he appeared to be in his seventies.  Omalu suspected that Weber’s brain would show signs of the advanced deterioration seen in late-stage Alzheimer’s Disease, but upon macroscopic examination the brain appeared normal. 

He then fixed slides of brain slices and discovered that there was an unusually high build-up of tau evident globally, with most accumulation in the gyri and sulci of the cerebral cortex.  This was the neuropathological “smoking gun.”

Repetitive closed head trauma has been described in contact sports across the board (including, but not limited to): boxing, wrestling, lacrosse, skiing, rugby, and soccer, as well as football.

Though the chronic neuroencephalopathies associated with repetitive brain injury are best known in boxing (in the form of dementia pugilistica), verified CTE has been identified in professional football players, professional wrestlers, and soccer players, as well as those suffering from seizure disorders, head bangers*, and domestic abuse victims.  People beating their loved-ones into brain damage.  
Post-Concussive Syndrome has also been identified in those participating in hockey, rugby, martial arts, horse riding and parachuting.

So I am torn between my love of sports and my passion for neurophysiology.  The dichotomy is plain to see when I ride my motorcycle to the hospital after being called in to determine brain death in a patient.  The neurosurgeon on call proffered a Donor Card once, and I pulled my own out of my wallet.

I think of all the hits I put on other players while playing ball, and all the ones they put on me.  I think of the kicks to the head I sustained in martial arts, and the snowmobiling accident that damaged my knee and almost broke my nose as my face shattered the windscreen. 

I think that all contact sports will continue to experience head trauma; it has also been determined that sub-concussive injuries lead to the same encephalic damage that precipitates CTE.  But neither big hits nor the injuries they cause will ever be eliminated from football.

Just the hits sustained by kids in Pop Warner Leagues are enough to bring about the precursors of the disease.  How many subclinical injuries have been sustained by the child before he or she even enters high school?

If just ten-percent of mothers refused to let their kids play football, the NFL would collapse. This is why the NFL has been fighting Dr. Omalu et al with all their might.  Only recently have they reluctantly began to acknowledge even the mere existence of CTE.  To the NFL’s credit, they, without any admission of responsibility, donated $50 million to Boston University, where the research on CTE began in earnest.

Sports are integral to Man, to Homo Sapiens Sapiens.  Evidence of sports has been found in cultures thousands of years gone.  The Sumerians raced horses.  The Assyrians, Hittites and Egyptians had chariot races; we all know about the Greeks and their Olympics.  The Romans, of course, had the Gladiatorial “games.”

As a species we compete, perhaps a throwback to the times when physical prowess attracted a mate.  We are a species prone to violence as default; our hypothalami demand action in stress situations.  We started wars for land, and we evolved to wars of attrition.  We will always cheer the hard hits, yelling “Get him!  Knock him OUT!”  and we will never sate this oddly attractive thirst.

Knowing what I know about neurophysiology, I would be hard-pressed to permit a child of my own to play football.  “Want to be an athlete? Be a danseur/ballerina.  They’re the true athletes,” I would tell him or her.  “And they have much fewer head injuries . . .”

* The use of the term, "head bangers" may not be exactly what you think it is.  Headbanger is a term used in medicine for those who repeatedly bash their crania against the wall or  floor or other sturdy object.  This usually presents in those who are mentally ill or neurologically challenged, as if those afflictions aren't cruel enough.
