Concussion in Football

Football players are more likely to sustain a concussion than kids who play other sports.

Football is a contact sport that requires players to collide with each other. "When you think about athletes that play football, it's a very physical sport," says Margot Putukian, MD, director of athletic medicine services at Princeton University. "They're going out to battle. There are a lot of analogies to wartime combat."

Effects of Concussion

Your brain is cushioned by a layer of fluid inside your skull. A sharp hit can cause your brain to bump the inside of your skull, causing an injury called a concussion. A concussion is more than just a simple bruise to the brain. This type of injury can make your brain stretch and swell. And when brain cells get damaged, chemical changes occur resulting in memory loss, difficulty thinking, mood swings, and changes in personality.

Signs and Symptoms of Concussion

Tell a coach or your parents immediately if you experience:

Any loss of consciousness is considered a strong warning sign of concussion. Football players with concussions also might:

  • Appear dazed or stunned
  • Speak slowly or slur speech
  • Forget what they're supposed to do
  • Become confused about their position on the field
  • Stagger or move clumsily
  • Answer questions slowly
  • Have trouble remembering what happened before getting hit
  • Display changes in mood, behavior or personality
  • Have one pupil larger than the other

Other serious symptoms of concussion include:

It's important to understand that symptoms do not always appear right after the hit. You might feel fine at first, but hours later have a headache, nausea, or blurred vision.

Any player showing these symptoms should be pulled out of the game immediately and be checked by a doctor as soon as possible. These symptoms can last for days or weeks, and rest is the only cure. If you do have a concussion, you should not return to play or practice until a doctor says it's safe.

That's because the brain of a person with a concussion is more vulnerable to further injury. And a player with a concussion who receives another blow to the head might suffer what's called "second-impact syndrome." A second impact can cause serious brain damage or even death.

The brain injuries caused by multiple concussions also might add up over time. Some studies have shown that people who experience more than one concussion during their lifetime have a harder time learning or solving problems. And the risk of lasting damage increases for people who receive more than one concussion.
