Concussion: Prevention or Treatment?

Everyone already heard “Prevention is better than cure”. But when we are talking about concussion, things get more complicated.
First of all: What is concussion?
Concussion is a type of traumatic brain injury caused by a direct impact on the head. The impact initiates a series of chemical events inside the brain that leads the neurons (brain cells) to a “energy crisis”. First, the impact causes physical injury in the neurons, affecting the control of what comes in and what comes out of the cell. Then, with uncontrolled flux of chemicals, the cell goes down in an energy crisis. This energy crisis can lead to later impairment in cognitive functions as memory and learning. So, whenever you hit your head, you need to rest until your body restore the normal functioning of your neurons.
Researches have shown how repeated concussions are more harmful than a single concussion.

Due to that, much is said about playing Football, Hockey, and other sports that may lead to concussions. It is clear that these kind of sports can be violent and a lot of times harmful, but ending them will not end with concussions. People can have concussions in ANY situation: taking shower, walking in the snow, going down stairs, running, etc.
It is also important to highlight that sports are part of culture. Football is a great piece of American culture, and ending it to prevent concussions would not be effective and would be unfavorable to the whole culture.
So, in this case, would not be better to put efforts and to focus in the treatment of concussion, rather than the prevention?
