One more time, I'm going to write about concussions.
For the past couple of years, concussions have dominated the
popular and medical news media. Several
high profile cases have focused a lot of attention on an arena that really
deserves a lot of attention.
Not that many years ago, if you could remember what you had
for lunch (after a blow to the head, or after you got your "bell
rung"), you went right back in the game.
The present state of awareness really started with a study
that came out in 1994 that revealed evidence of significant brain trauma in NFL
players that did not have a history of concussions.
Since then, lot of research and study has been done on the
long term ramifications of concussions.
And the results are scary. What we do know is that concussions are not
to be taken lightly. We know that there
are long term effects even to relatively minor head trauma.
That when you "got your bell rung," actual damage
was done, damage that could surface many years down the road.
And lest you think it is just a football thing, let me
assure you that it is not. Any active individual can get a concussion. (Heck, even an inactive individual can trip
and fall in the bathroom and get a concussion.)
So, when is it a concussion and when is it just a bump on
the head?
Without getting all medical about it (and because there
really isn't a single definition of a concussion), a concussion is a blow to
the head that disrupts the function of the brain.
It may manifest itself as a headache, dizziness, nausea,
blurred vision, or memory loss. It can be slight, maybe where a blow to the
head leaves you with a mild headache, to severe, in which you lose
consciousness. Either way, we take it
seriously.
In sports, we start our evaluation immediately. Decisions about how to deal with an
unconscious athlete are simple--immobilize them, protect them, and get them
transported to the nearest hospital in an ambulance.
It's all those lesser injuries that take up most of our
attention.
We start by administering a standardized set of questions
useful in determining cognitive function.
Simple questions, really, but useful in deciding if the brain function
has been impaired in any way.
We perform
balance testing , which can provide very important early information.
If symptoms go away quickly, we will just monitor their
progress but the game that day at that time is over.
Lingering symptoms used to mean staying up till quite late,
watching for cognitive deterioration. If
there are several hours between injury and bedtime and the symptoms are not
getting worse, sleep is generally OK.
Once they have no symptoms and have been cleared by their
physician, we administer an ImPACT test, a computerized test of how the brain
is functioning. Along the way, we
strongly (in no uncertain terms) insist that the athlete be honest about
symptoms. We don't want them hiding
things from us.
If they have medical clearance and a negative ImPACT test,
it still isn't over. Our athletes then
have to go through a series of exercises and activities that can take up to two
weeks to complete and that's only if they have no recurrence of their symptoms.
This is one arena where we just don't take any chances.
