Author's Note: After getting a concussion earlier this
year, the science behind the injury interested me. I wanted to know what made
the injury so much more dangerous, and why the injury was handled
differently.
Every athlete hears about the danger of concussions, and the
consequences of not telling somebody if you are suffering symptoms like a
headache or blurred vision, but what is there really at stake. What is really
going to happen to if they continue to stay active throughout a concussion? Why
do they have to sit out, even when the symptoms are gone? Why is a concussion
treated differently from any other injury. What is a concussion is the question that will probably make you think before ever playing through a concussion.
The first thing to understand is what a concussion is. In
Latin, concussion literally means to shake violently, which is what happens
when someone experiences extreme forces to the head; the brain shakes
violently. As the brain whips around in the head, it comes in contact with the
skull, and the damage from these impacts are often the worst of the injury. As
the brain comes in contact with the skull, brain cells are damaged and this is
what typically causes the loss of memory and loss of consciousness for seconds
or even minutes in some cases. Even though the injury seems dangerous, a concussion
is put in the mild traumatic brain injury category because a concussion itself
is less severe than many other injuries that occur to the brain from blunt
force contact. The common symptoms of a concussion are very similar to that of
a typical headache: sensitivity to light and sound, fatigue, and difficulty
sleeping, so every sports related headache is treated as a concussion until
they know that it is just a headache. Caution is taken especially in sports
like football, but why is this? Why do we treat big hits differently in
different sports?
Concussions are most associated with boxing and football, as
the high majority of sports related concussions occur on the field or in the
ring, but there are many other sports where head related injuries occur. Most statistics show that about 15-20% of
high school basketball players suffer from concussions, and a scary 36% of girl
soccer players sustain at least one concussion, but sports still only account
for less than half of concussions in teens. Concussions happen everywhere, but
a concussion that is cared for properly typically is not a major problem. What
becomes a problem is when a concussion is not cared for, there is not enough
time removed from activity, or a second concussion occurs before the first concussion
has fully healed. A second concussion before the brain is healed leads to what
is called Second Impact Syndrome, and in most cases, death. The true danger of
concussions isn’t in a first blow to the head, it is in the incorrect care of
the injury, and the second impact could happen even in everyday life.
Second impact syndrome has taken 20 lives in the past 10
years, and has altered the life of others. The rare condition occurs only in
kids and young adults under the age of 22 whose brain is still developing. Swelling
of the brain is the most severe of the symptoms to come from second impact
syndrome. To relieve pressure from the brain, skull removal is normal to
survive the horrible condition, and traumatic brain damage is almost a given
for survivors. Why is the question
though? Why does a second impact do so much more damage than the first? The
answer lies in the in the anatomy of a concussion and the body.
When a concussion occurs, potassium is released out of the
neurons as calcium seeps into the neurons, causing a chemical imbalance. Potassium
is in the body to help control muscle contractions, and lack of potassium has
been proven to cause an irregular heart beat. When the brain is allowed to
fully recover after a concussion, potassium and calcium slowly balance out.
When a second impact occurs to the head before the brain is fully healed, the
lack of potassium allows the brain to swell well beyond safe levels. As the
swelling brain comes in contact with the skull, pressure builds, and there is a
chance of dying from lack of oxygen to the brain or by losing important brain
cells. The danger first of a concussion is minimal, but a second concussion is
as dangerous as anything.
This is why you have to sit out of when you get a
concussion. This is why you can’t treat a concussion like any other injury.
This is why you have to be sure with a concussion. For those people who thought
that all the worry over a concussion and the constant papers and speeches were
all a little much, they are probably right. The nonstop seminars and constant
talk in professional sports are probably a little extreme, but the
understanding of a concussion can save someone’s life. This is why every athlete
is bombarded with the danger of concussions, because there is always somebody out there who can
learn something more about concussions, and you never know which piece of
information will help someone make the right decision. With the understanding
of a concussion comes a realization that should ease everybody’s minds. A wrong decision is the true danger of a
concussion, not the injury itself.
