A
hundred years ago, battlefield soldiers who exhibited neurological symptoms like
insomnia, tremors and hypersensitivity to noise without showing visible wounds
were often charged with cowardice. Eventually (and reluctantly) the term “shell
shock” was coined to describe the injuries that caused disrupted lives decades
after the end of the First World War.
As
we progressed through a century’s worth of wars, we referred to the condition
as battle fatigue and then Post-Traumatic Stress Disorder (PTSD). We’re still
somewhat ambivalent about the diagnosis, and treatment is also a bit of a crapshoot,
depending upon both enlightened clinicians and funding of resources.
(During
World War II, the Royal Air Force actually distinguished “medical casualties”
from those classified as Lacking Moral Fibre (LMF). It was a diagnosis intended
to prevent shirkers of combat missions turning their experience to profit as
private pilots.)
We’re
much more adept at sending men and women off to fight than we are at caring for
them after they return. If they return.
So I
was very heartened by this report out of NPR this week about a
medical researcher and combat veteran who answered the unspoken call for help
from a comrade, switched specialties and hung on for a decade to hunt down
the physiological factors that constitute what we now call Traumatic Brain
Injuries (TBIs). We are in the midst of a bumper crop of TBIs, thanks to the
use of improvised explosive devices (IEDs) in Iraq and Afghanistan, so Kit
Parker and his team are meeting a critical need.
There
are several parts to this story that are worth highlighting.
We’re
a hundred years on from the Western Front, with incredible advances in both
life-ending and life-saving technologies, and we’re still teetering at the edge of the Dark Ages in terms of how we
characterize the human costs of warfare. As one of the on-the-ground investigative
leaders put it, “If you don’t have blood coming out of your head, if you don’t
have a penetrating injury, you’re fine, everything’s OK, have a nice day.”
I love
the way that Parker, a Harvard biophysicist specializing in the cellular workings
of the heart as a muscle, essentially sat still and listened to what was not
being said when his National Guard comrade Chris Moroski called him. He heard
what his friend didn’t have the words to ask for, and he took action to ensure
that Moroski got proper diagnosis and care for his TBI.
Then
he took extraordinary action to ensure that others
with TBI would also get proper diagnoses and care. Because he changed his
research focus from the heart to the brain to understand how blast waves
produced by IEDs physically disrupt brain tissue and function. Until he started
his inquiry, no one had investigated this.
There
have been some exceptional people working on unravelling this mystery, and I
love how they’ve been unremitting in their pursuit of nailing down the cause of
these injuries, and laying out preventive and therapeutic measures to protect
soldiers. Many of them are combat veterans, but they all have that scientific
curiosity that drives them to pursue “ground truth”. I applaud their tenacity
and devotion; may their funding never wither away.
I am
not at all surprised by the fact that there’s no corresponding research into
drug therapies because pharmaceutical companies can’t see profits in the
prospect of repairing broken brains, so they don’t see any merit to investing
in it—even though TBIs are sustained in a lot of non-combat situations like
auto accidents. They haven’t found a way to rake in millions from Alzheimer’s;
they’re not going to piss away bench scientists on TBI when they can tweak the
formula of Viagra or Lipitor, file new patents and spend that money on
advertising direct to the consumer.
(If
anyone should be labeled as LMF, it’s Big Pharma.)
So
Parker’s team continues to work on gathering the data that will eventually lead
to something that might entice some drug company to produce a treatment. NPR’s
going to continue reporting on this, and I’m looking forward to following the
story. This is why we need basic and applied science, and this is why we need to know about it.
