Ever heard of CTE? How about chronic traumatic encephalopathy (that’s a mouthful!) or punch drunk? Well if you haven’t heard of it listen (or read) up. Chronic traumatic encephalopathy is caused by repeated brain trauma, think of boxers or football players. Remember Dave Duerson, Junior Seau and Adrian Robinson? Well all of these professional football players committed suicide, and all were diagnosed with CTE after their death.

So...what is CTE?

CTE is caused by repeated brain trauma. When we get hit in the head or our bodies absorb a heavy blow our brains slosh around inside of our skulls and hit the “walls”. This causes a concussion, which is a bruise on the brain. For a time the injury to the brain changes how your brain works, causing headaches, memory problems, trouble concentrating, and problems with balance/coordination. If you’ve had a particularly bad concussion, after a while you may feel fine but your brain may still be recovering. In addition everyone takes a different amount of time to heal. It’s not like a broken arm where you can pretty much insure that after 4-6 weeks it will be healed. And since a concussion is not visible to anyone just looking at you, a coach, for example may pressure you to come back to the game before your brain is healed.

Imagine the amount of pressure a professional football player is under to return to the games, even if their concussion isn’t healed. Interestingly enough, football helmets don’t prevent all concussions, but they certainly are an improvement on the leather skull caps players used to wear. One concussions effects are not permanent, but repeated concussions over time, you guessed it... cause permanent and degenerative brain damage.

This is why so many athletes in competitive contact sports, especially professional athletes, have issues with their brain as they age (dementia). CTE is somewhat similar to Alzheimer's and dementia in the way that it progresses over time, and the way it changes the person with it. But unlike either Alzheimer's and dementia, CTE doesn’t wait until old age to start, there is no way to definitively diagnose CTE while the victim is alive, and there are no treatments for it.

When the brain is functioning normally the neurons pass along signals through the axon to other cells. When a person gets a concussion the neurons are not able to send messages over the axons for a little. With repeated concussions the axons actually start to unravel and the Tau protein that held them together breaks off and starts to collect in certain areas. After the axon has broken apart it cannot be repaired and the neuron, unable to communicate, dies. As CTE progresses more Tau collects which means that neurons are dying. So essentially the Tau breakup strangles the brain and decreases function. Which is why the person with the disease experiences personality changes much like a Alzheimer's or dementia patient. There are many symptoms of CTE, including depression and suicidal behavior. Which is why so many victims of CTE kill themselves. As the disease progresses a person may exhibit many different symptoms.


Since CTE is not very well understood at this time, early prevention is the recommended course of treatment. If a person never receives the concussions that cause CTE, CTE will logically never develop. As I said earlier, the protection equipment we have doesn’t 100% stop concussions, and many contact sports don’t have anything that even attempts to protect the brain (rugby, wrestling, soccer). And many people ignore their concussions and “fight through the pain”, although this may give you temporary notoriety, it is doing far more damage. Take care of your brain, there are plenty of diseases out there that happen naturally, you don’t need to tempt fate by causing a preventable disease to yourself.

5 Things To Do That Are Better Than Writing A Paper

Don't waste your time trying to write that paper when there are so many more interesting things you could be doing.

Writing a paper is never fun and is rarely rewarding. The writer's block, the page requirement, be specific, but don’t summarize, make sure you fixed any grammatical errors, did you even use spellcheck? and analyze, analyze, analyze.

Papers can be a major pain. They take up so much time and effort that by the end of the process you hate yourself and you hate the professor for making life so difficult. Questions of your existence start roaming in your mind. Am I even cut out for college if I can’t write a single paper? Am I even capable of taking care of myself if I lack the energy to open my laptop and start typing?

10 Reasons Why Sisters Are The Best

Who could be a better friend than your own sister?

sisters
Taylor Hooper

I can barely remember back when I was the only child. Most would say it’s because it is extremely difficult to remember things as a toddler but I would say it's because I was bored until my sister came along. My mother always says how important the "sister bond" is and with every year that passes I realize how right she is. Instead of writing a novel about all of the wonderful things there are about having a sister I decided to list a few of them instead.

It is the time of our lives that we are beginning to enter the adult world and most of us, if not all of us, have no idea what we are doing. It's like starting a video game, but skipping the tutorial. We're all just running around aimlessly hoping we accidentally do something right that moves us along the right path. Now that graduation has just happened, or is right around the corner for some of us, it's time to start thinking about how we are going to take care of ourselves once we are on our own.
